122-680: The Royal Bahraini Air Force ( Arabic : سلاح الجو الملكي البحريني , abbreviated as RBAF , formerly known as Bahrain Amiri Air Force ) is the aerial warfare branch of the Bahrain Defence Force (BDF). Originally formed as the BDF Air Wing in 1976, it became an independent service branch in 1987. The RBAF was involved in combat operations during the Gulf War and the Saudi-led intervention in
244-561: A SARH (semi-active radar homing) variant (AIM-9C) and an IR (AIM-9D) in 1963. The AIM-9C's semi-active radar was exclusively tied to the F-8 Crusader 's radar and fire control system (FCS). A total of around 1,000 AIM-9C missiles were launched from 1965 to 1967, but their usage in Vietnam war proved unsuccessful, downing no enemies. A filter modification program for reworked units (to allow high altitude capability up to 18,288m (60,000 feet) This
366-531: A solid rocket motor for propulsion, similar to most conventional missiles, a continuous-rod fragmentation warhead , and an infrared seeker . The seeker tracks a difference in temperatures detected and uses proportional guidance to achieve impact. Older variants such as the AIM-9B with uncooled seeker heads could only track the high temperatures of engine exhaust , making them strictly rear aspect. Later variants, however, featured liquid nitrogen coolant bottles in
488-562: A collection of related dialects that constitute the precursor of Arabic, first emerged during the Iron Age . Previously, the earliest attestation of Old Arabic was thought to be a single 1st century CE inscription in Sabaic script at Qaryat al-Faw , in southern present-day Saudi Arabia. However, this inscription does not participate in several of the key innovations of the Arabic language group, such as
610-693: A contract to support Sidewinder operations through to 2055. Air Force spokeswoman Stephanie Powell said that its relatively low cost, versatility, and reliability mean it is "very possible that the Sidewinder will remain in Air Force inventories through the late 21st century". The AIM-9 was a product of the US Naval Weapons Center at China Lake in the Mojave Desert . It features a lightweight, compact design with cruciform canards and tail fins. It uses
732-435: A corpus of poetic texts, in addition to Qur'an usage and Bedouin informants whom he considered to be reliable speakers of the ʿarabiyya . Arabic spread with the spread of Islam . Following the early Muslim conquests , Arabic gained vocabulary from Middle Persian and Turkish . In the early Abbasid period , many Classical Greek terms entered Arabic through translations carried out at Baghdad's House of Wisdom . By
854-1077: A dialect of Arabic and written in the Latin alphabet . The Balkan languages, including Albanian, Greek , Serbo-Croatian, and Bulgarian , have also acquired many words of Arabic origin, mainly through direct contact with Ottoman Turkish . Arabic has influenced languages across the globe throughout its history, especially languages where Islam is the predominant religion and in countries that were conquered by Muslims. The most markedly influenced languages are Persian , Turkish , Hindustani ( Hindi and Urdu ), Kashmiri , Kurdish , Bosnian , Kazakh , Bengali , Malay ( Indonesian and Malaysian ), Maldivian , Pashto , Punjabi , Albanian , Armenian , Azerbaijani , Sicilian, Spanish, Greek, Bulgarian, Tagalog , Sindhi , Odia , Hebrew and African languages such as Hausa , Amharic , Tigrinya , Somali , Tamazight , and Swahili . Conversely, Arabic has borrowed some words (mostly nouns) from other languages, including its sister-language Aramaic, Persian, Greek, and Latin and to
976-519: A heat-homing rocket. The name Sidewinder was selected in 1950 and is the common name of Crotalus cerastes , a rattlesnake , which uses infrared sensory organs to hunt warm-blooded prey. It did not receive official funding until 1951 when the effort was mature enough to show to Admiral William "Deak" Parsons , the Deputy Chief of the Bureau of Ordnance (BuOrd). It subsequently received designation as
1098-483: A lesser extent and more recently from Turkish, English, French, and Italian. Arabic is spoken by as many as 380 million speakers, both native and non-native, in the Arab world, making it the fifth most spoken language in the world, and the fourth most used language on the internet in terms of users. It also serves as the liturgical language of more than 2 billion Muslims . In 2011, Bloomberg Businessweek ranked Arabic
1220-623: A letter of offer and acceptance for nine UH-60M Black Hawk helicopters to be purchased as part of the Foreign Military Sales program through the United States Army. These are designated for use in a variety of roles, including combat search and rescue. They were the international launch customer for the UH-60M variant of the venerable S-70 helicopter family. Deliveries commenced on 1 December 2009 A single Sikorsky S-92 VVIP helicopter
1342-677: A millennium before the modern period . Early lexicographers ( لُغَوِيُّون lughawiyyūn ) sought to explain words in the Quran that were unfamiliar or had a particular contextual meaning, and to identify words of non-Arabic origin that appear in the Quran. They gathered shawāhid ( شَوَاهِد 'instances of attested usage') from poetry and the speech of the Arabs—particularly the Bedouin ʾaʿrāb [ ar ] ( أَعْراب ) who were perceived to speak

#17328512321301464-685: A new nose dome and superior optical filtering. Conversions were done to European AIM-9B to upgrade them to the FGW.2 standard. The official designation is the AIM-9B FGW.2 but it is known as the AIM-9F in US nomenclature. The AIM-9G was very similar to the AIM-9D in most aspects, and did not differ externally. The AIM-9G was an AIM-9D that used an improved AIM-9D seeker head with SEAM (Sidewinder Extended Acquisition Mode), this allowed
1586-744: A pilot academy based around the Hawk Trainer , similar to the NFTC in Canada . Subsequently, orders were placed for Slingsby T67 Firefly and BAE Hawk trainers. The first trainers were delivered in October 2006. After Bahrain became a monarchy on 14 February 2002, the BAAF was renamed the Royal Bahraini Air Force. Upgrade of the helicopter force has included new utility transports, and on 19 June 2007, Bahrain signed
1708-617: A program in 1952. Originally called the Sidewinder 1 , the first live firing was on 3 September 1952. The missile intercepted a drone for the first time on 11 September 1953. The missile carried out 51 guided flights in 1954, and in 1955 production was authorized. In 1954, the US Air Force carried out trials with the original AIM-9A and the improved AIM-9B at the Holloman Air Development Center. The first operational use of
1830-481: A radio proximity fuze could be used. These improvements were all added into AIM-9D and went into service with the USN. Around 1,000 AIM-9D units were produced from 1965 to 1969. The primary problem of the AIM-9D was breakup during launch. The AIM-9D was eventually developed into AIM-9G. ATM-9D (USN) : AIM-9D used for captive flight target acquisition training. GDU-1/B : AIM-9D used for firing practice. The AIM-9E "Echo"
1952-576: A result, many European languages have borrowed words from it. Arabic influence, mainly in vocabulary, is seen in European languages (mainly Spanish and to a lesser extent Portuguese , Catalan , and Sicilian ) owing to the proximity of Europe and the long-lasting Arabic cultural and linguistic presence, mainly in Southern Iberia, during the Al-Andalus era. Maltese is a Semitic language developed from
2074-462: A script derived from ASA attest to a language known as Hasaitic . On the northwestern frontier of Arabia, various languages known to scholars as Thamudic B , Thamudic D, Safaitic , and Hismaic are attested. The last two share important isoglosses with later forms of Arabic, leading scholars to theorize that Safaitic and Hismaic are early forms of Arabic and that they should be considered Old Arabic . Linguists generally believe that "Old Arabic",
2196-465: A single language, despite mutual incomprehensibility among differing spoken versions. From a linguistic standpoint, it is often said that the various spoken varieties of Arabic differ among each other collectively about as much as the Romance languages . This is an apt comparison in a number of ways. The period of divergence from a single spoken form is similar—perhaps 1500 years for Arabic, 2000 years for
2318-420: A spinning disk with lines painted on it, alternately known as a "reticle" or "chopper". The reticle spun at a fixed speed, causing the output of the photocell to be interrupted in a pattern, and the precise timing of the resulting signal indicated the bearing of the target. Although Hamburg and similar devices like Madrid were essentially complete, the work of mating them to a missile had not been carried out by
2440-503: A type of Arabic. Cypriot Arabic is recognized as a minority language in Cyprus. The sociolinguistic situation of Arabic in modern times provides a prime example of the linguistic phenomenon of diglossia , which is the normal use of two separate varieties of the same language, usually in different social situations. Tawleed is the process of giving a new shade of meaning to an old classical word. For example, al-hatif lexicographically means
2562-499: A variety of regional vernacular Arabic dialects , which are not necessarily mutually intelligible. Classical Arabic is the language found in the Quran , used from the period of Pre-Islamic Arabia to that of the Abbasid Caliphate . Classical Arabic is prescriptive, according to the syntactic and grammatical norms laid down by classical grammarians (such as Sibawayh ) and the vocabulary defined in classical dictionaries (such as

#17328512321302684-846: A wide variety of missile projects were underway, from huge systems like the Bell Bomi rocket-powered bomber to small systems like air-to-air missiles. By the early 1950s, both the US Air Force and Royal Air Force had started major IR seeker missile projects. The development of the Sidewinder missile began in 1946 at the Naval Ordnance Test Station (NOTS), Inyokern, California, now the Naval Air Weapons Station China Lake , as an in-house research project conceived by William B. McLean . McLean initially called his effort "Local Fuze Project 602" using laboratory funding, volunteer help and fuze funding to develop what they called

In the wake of the industrial revolution and European hegemony and colonialism , pioneering Arabic presses, such as the Amiri Press established by Muhammad Ali (1819), dramatically changed the diffusion and consumption of Arabic literature and publications. Rifa'a al-Tahtawi proposed the establishment of Madrasat al-Alsun in 1836 and led a translation campaign that highlighted
2928-727: Is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world . The ISO assigns language codes to 32 varieties of Arabic , including its standard form of Literary Arabic, known as Modern Standard Arabic , which is derived from Classical Arabic . This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as al-ʿarabiyyatu l-fuṣḥā ( اَلعَرَبِيَّةُ ٱلْفُصْحَىٰ "the eloquent Arabic") or simply al-fuṣḥā ( اَلْفُصْحَىٰ ). Arabic
3050-585: Is a minimum level of comprehension between all Arabic dialects, this level can increase or decrease based on geographic proximity: for example, Levantine and Gulf speakers understand each other much better than they do speakers from the Maghreb. The issue of diglossia between spoken and written language is a complicating factor: A single written form, differing sharply from any of the spoken varieties learned natively, unites several sometimes divergent spoken forms. For political reasons, Arabs mostly assert that they all speak
3172-535: Is a short-range air-to-air missile . Entering service with the United States Navy in 1956 and the Air Force in 1964, the AIM-9 is one of the oldest, cheapest, and most successful air-to-air missiles. Its latest variants remain standard equipment in most Western-aligned air forces. The Soviet K-13 (AA-2 "Atoll"), a reverse-engineered copy of the AIM-9B, was also widely adopted. Low-level development started in
3294-542: Is a sister language rather than their direct ancestor. Arabia had a wide variety of Semitic languages in antiquity. The term "Arab" was initially used to describe those living in the Arabian Peninsula , as perceived by geographers from ancient Greece . In the southwest, various Central Semitic languages both belonging to and outside the Ancient South Arabian family (e.g. Southern Thamudic) were spoken. It
3416-469: Is a very limited weapon, but it had no serious competitors and counters when it was introduced, causing it to be adopted by the USAF and NATO as a standard weapon, with around 80,000 units being produced from 1958 to 1962. The viewing angle of the AIM-9B's sensor was a minuscule 4 degrees, so at launch, the pilot had to accurately aim the aircraft's sight over or above the target (to account for drag). The speed of
3538-469: Is believed that the ancestors of the Modern South Arabian languages (non-Central Semitic languages) were spoken in southern Arabia at this time. To the north, in the oases of northern Hejaz , Dadanitic and Taymanitic held some prestige as inscriptional languages. In Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested. In eastern Arabia, inscriptions in
3660-408: Is credited with establishing the rules of Arabic prosody . Al-Jahiz (776–868) proposed to Al-Akhfash al-Akbar an overhaul of the grammar of Arabic, but it would not come to pass for two centuries. The standardization of Arabic reached completion around the end of the 8th century. The first comprehensive description of the ʿarabiyya "Arabic", Sībawayhi's al - Kitāb , is based first of all upon
3782-468: Is credited with standardizing Arabic grammar , or an-naḥw ( النَّحو "the way" ), and pioneering a system of diacritics to differentiate consonants ( نقط الإعجام nuqaṭu‿l-i'jām "pointing for non-Arabs") and indicate vocalization ( التشكيل at-tashkīl ). Al-Khalil ibn Ahmad al-Farahidi (718–786) compiled the first Arabic dictionary, Kitāb al-'Ayn ( كتاب العين "The Book of the Letter ع "), and

3904-564: Is more accurate and somewhat more resistant to countermeasures. The new rocket motor burns longer and the redesigned body makes the R-13M more maneuverable. K-13M1/R-13M1 : Improved R-13M with new forward fins introduced in 1976. The lackluster performance of the AIM-9B caused the Navy to look for successor. And in 1963 the AAM-N-7 Sidewinder IC was designed, It was developed in two variations:
4026-566: Is not present in the spoken varieties, but deletes Classical words that sound obsolete in MSA. In addition, MSA has borrowed or coined many terms for concepts that did not exist in Quranic times, and MSA continues to evolve. Some words have been borrowed from other languages—notice that transliteration mainly indicates spelling and not real pronunciation (e.g., فِلْم film 'film' or ديمقراطية dīmuqrāṭiyyah 'democracy'). The current preference
4148-836: Is official in Mali and recognized as a minority language in Morocco, while the Senegalese government adopted the Latin script to write it. Maltese is official in (predominantly Catholic ) Malta and written with the Latin script . Linguists agree that it is a variety of spoken Arabic, descended from Siculo-Arabic , though it has experienced extensive changes as a result of sustained and intensive contact with Italo-Romance varieties, and more recently also with English. Due to "a mix of social, cultural, historical, political, and indeed linguistic factors", many Maltese people today consider their language Semitic but not
4270-559: Is the third most widespread official language after English and French, one of six official languages of the United Nations , and the liturgical language of Islam . Arabic is widely taught in schools and universities around the world and is used to varying degrees in workplaces, governments and the media. During the Middle Ages , Arabic was a major vehicle of culture and learning, especially in science, mathematics and philosophy. As
4392-584: Is the variety used in most current, printed Arabic publications, spoken by some of the Arabic media across North Africa and the Middle East, and understood by most educated Arabic speakers. "Literary Arabic" and "Standard Arabic" ( فُصْحَى fuṣḥá ) are less strictly defined terms that may refer to Modern Standard Arabic or Classical Arabic. Some of the differences between Classical Arabic (CA) and Modern Standard Arabic (MSA) are as follows: MSA uses much Classical vocabulary (e.g., dhahaba 'to go') that
4514-413: Is to avoid direct borrowings, preferring to either use loan translations (e.g., فرع farʻ 'branch', also used for the branch of a company or organization; جناح janāḥ 'wing', is also used for the wing of an airplane, building, air force, etc.), or to coin new words using forms within existing roots ( استماتة istimātah ' apoptosis ', using the root موت m/w/t 'death' put into
4636-516: Is used to denote concepts that have arisen in the industrial and post-industrial era , especially in modern times. Due to its grounding in Classical Arabic, Modern Standard Arabic is removed over a millennium from everyday speech, which is construed as a multitude of dialects of this language. These dialects and Modern Standard Arabic are described by some scholars as not mutually comprehensible. The former are usually acquired in families, while
4758-445: The Lisān al-ʻArab ). Modern Standard Arabic (MSA) largely follows the grammatical standards of Classical Arabic and uses much of the same vocabulary. However, it has discarded some grammatical constructions and vocabulary that no longer have any counterpart in the spoken varieties and has adopted certain new constructions and vocabulary from the spoken varieties. Much of the new vocabulary

The Sidewinder is the most widely used air-to-air missile in the West, with more than 110,000 missiles produced for the U.S. and 27 other nations, of which perhaps one percent have been used in combat. It has been built under license by Sweden and other nations. The AIM-9 has an estimated 270 aircraft kills. In 2010, Boeing won

After Bahraini air crews became familiar with the F-5, they underwent training to prepare to use the F-16 Fighting Falcon . The first Bahraini F-16s, the F-16C/D variants, were acquired in 1990. This made Bahrain the first Gulf country to use
5246-561: The Xth form , or جامعة jāmiʻah 'university', based on جمع jamaʻa 'to gather, unite'; جمهورية jumhūriyyah 'republic', based on جمهور jumhūr 'multitude'). An earlier tendency was to redefine an older word although this has fallen into disuse (e.g., هاتف hātif 'telephone' < 'invisible caller (in Sufism)'; جريدة jarīdah 'newspaper' < 'palm-leaf stalk'). Colloquial or dialectal Arabic refers to
5368-427: The conical scan was very slow, additionally, the uncooled missile had a low sensitivity and was liable to extraneous heat. The AIM-9B was recommended for use on non-threatening targets (like bombers), only from behind (so it can lock on the thermal radiation from the target engines) and only with the sun behind or to the side of the launching aircraft (as the missile would lock onto it due to its thermal radiation). It
5490-494: The northern Hejaz . These features are evidence of common descent from a hypothetical ancestor , Proto-Arabic . The following features of Proto-Arabic can be reconstructed with confidence: On the other hand, several Arabic varieties are closer to other Semitic languages and maintain features not found in Classical Arabic, indicating that these varieties cannot have developed from Classical Arabic. Thus, Arabic vernaculars do not descend from Classical Arabic: Classical Arabic
5612-419: The "learned" tradition (Classical Arabic). This variety and both its classicizing and "lay" iterations have been termed Middle Arabic in the past, but they are thought to continue an Old Higazi register. It is clear that the orthography of the Quran was not developed for the standardized form of Classical Arabic; rather, it shows the attempt on the part of writers to record an archaic form of Old Higazi. In
5734-770: The "purest," most eloquent form of Arabic—initiating a process of jamʿu‿l-luɣah ( جمع اللغة 'compiling the language') which took place over the 8th and early 9th centuries. Kitāb al-'Ayn ( c. 8th century ), attributed to Al-Khalil ibn Ahmad al-Farahidi , is considered the first lexicon to include all Arabic roots ; it sought to exhaust all possible root permutations —later called taqālīb ( تقاليب ) — calling those that are actually used mustaʿmal ( مستعمَل ) and those that are not used muhmal ( مُهمَل ). Lisān al-ʿArab (1290) by Ibn Manzur gives 9,273 roots, while Tāj al-ʿArūs (1774) by Murtada az-Zabidi gives 11,978 roots. AIM-9 Sidewinder The AIM-9 Sidewinder ("AIM" for "Air Interception Missile")

The Nahda was a cultural and especially literary renaissance of the 19th century in which writers sought "to fuse Arabic and European forms of expression." According to James L. Gelvin , " Nahda writers attempted to simplify the Arabic language and script so that it might be accessible to
5978-562: The 4th to the 6th centuries, the Nabataean script evolved into the Arabic script recognizable from the early Islamic era. There are inscriptions in an undotted, 17-letter Arabic script dating to the 6th century CE, found at four locations in Syria ( Zabad , Jebel Usays , Harran , Umm el-Jimal ). The oldest surviving papyrus in Arabic dates to 643 CE, and it uses dots to produce the modern 28-letter Arabic alphabet. The language of that papyrus and of
6100-812: The 8th century, knowledge of Classical Arabic had become an essential prerequisite for rising into the higher classes throughout the Islamic world, both for Muslims and non-Muslims. For example, Maimonides , the Andalusi Jewish philosopher, authored works in Judeo-Arabic —Arabic written in Hebrew script . Ibn Jinni of Mosul , a pioneer in phonology , wrote prolifically in the 10th century on Arabic morphology and phonology in works such as Kitāb Al-Munṣif , Kitāb Al-Muḥtasab , and Kitāb Al-Khaṣāʾiṣ [ ar ] . Ibn Mada' of Cordoba (1116–1196) realized
6222-551: The AIM-9. Originally a tail-chasing system, early models saw extensive use during the Vietnam War , but had a low success rate (8% hit rate with the AIM-9E variant). This led to all-aspect capability in the L (Lima) version, which proved an effective weapon during the 1982 Falklands War and Operation Mole Cricket 19 in Lebanon. Its adaptability has kept it in service over newer designs like

The canard design was changed to a squared tip double delta planform, this helped improve canard behaviour at higher angles of attack (AOA). Over 5,000 AIM-9B's were rebuilt into AIM-9E's. The AIM-9E appeared in Vietnam after the conclusion of the Operation Rolling Thunder in 1968, with the U.S. Air Force (USAF), becoming one of their main missile armaments. Up until Operation Linebacker in 1972 intense air-to-air activity in Vietnam

The Bahrain Defence Force, which itself was formed in 1968, just before the country became independent from United Kingdom in 1971, first organized an air wing in May 1976 at Riffa Air Base , which received its first aircraft, four Bo 105 helicopters, in February 1977. This occurred after Bahrain sent the air wing's future members to receive training from allied countries in 1974. The small force grew gradually, receiving 12 Augusta Bell Twin Huey helicopters in 1978, and in

Before this, the country considered several American and European advanced fighter aircraft, including the F-15 Eagle , F-16 Fighting Falcon, F/A-18 Hornet , Mirage 2000 , and Tornado . Bahraini pilots were trained on F-16 operations at MacDill Air Force Base in Florida in 1989, and the first F-16 formally was handed over to the BAAF in March of that year. The first four F-16s were sent to Bahrain, flown by Bahraini pilots, in May 1990. Around this time
6832-486: The Gulf state hoped the first planes will be delivered in 2021. The sale of F-16 Vipers and related equipment to Bahrain was first approved by the U.S. State Department in 2016 during the Obama administration but it was delayed over human rights concerns. President Donald Trump dropped the human rights conditions last year. The State Department then approved the sale of 19 aircraft worth $ 2.78 billion, and another $ 1.1 billion to upgrade Bahrain's existing fleet of 20 F-16s to

A second batch of ten F-16s commenced delivery in 2000 under the Peace Crown II program. The new aircraft represented a further increase in the air force's combat capabilities, as they were equipped to carry the AMRAAM missile, first used by the USAF in 1992.

Arabic has been taught worldwide in many elementary and secondary schools, especially Muslim schools. Universities around
7198-431: The Navy opted for a different approach after Walt Freitag, a USN engineer proposed a full change to solid-state in one missile. The "H" variant had major changes over the AIM-9D/G, which had multiple issues with reliability. One of the issues was the intolerance of the vacuum tubes to repeated 20ft/sec sink rate landings by US Navy aircraft on carrier decks. The "H" was the first Sidewinder to be fully solid state, replacing
7320-474: The Qur'an is referred to by linguists as "Quranic Arabic", as distinct from its codification soon thereafter into " Classical Arabic ". In late pre-Islamic times, a transdialectal and transcommunal variety of Arabic emerged in the Hejaz , which continued living its parallel life after literary Arabic had been institutionally standardized in the 2nd and 3rd century of the Hijra , most strongly in Judeo-Christian texts, keeping alive ancient features eliminated from

Also, while it is comprehensible to people from the Maghreb , a linguistically innovative variety such as Moroccan Arabic is essentially incomprehensible to Arabs from the Mashriq , much as French is incomprehensible to Spanish or Italian speakers but relatively easily learned by them. This suggests that the spoken varieties may linguistically be considered separate languages. With

8174-404: The aircraft, rendering it inoperable. The continuous rod warhead features rods welded together to form a cylindrical outer shell, with explosive filler inside. Upon detonation, the rods are scattered in a toroidal shape, ensuring that at least some portion of the shrapnel hits enemy aircraft. Newer models of the AIM-9 sought to increase the range that the seeker head's gimbal can turn, allowing
8296-446: The amount of energy devoted to actuating control surfaces, the AIM-9 does not use active roll stabilization. Instead, it uses rollerons , small metal discs protruding out of the aft end of the tips of the tail fins which spin as the missile flies through the air, providing gyroscopic stabilization. The AIM-9 uses a passive infrared proximity fuze to detonate its warhead near an enemy aircraft, scattering shrapnel that aims to damage
8418-419: The construction of Isa Air Base was complete, which is where the Bahraini F-16s have been based. Both the F-16 and the F-5 were operated by Bahrain in the Gulf War , during which the BAAF carried out air strikes against Iraq . The new Bahraini F-16s were flown by the 1st Tactical Fighter Squadron in Operation Desert Storm, operating alongside coalition forces, which included 200 American aircraft based out of
8540-509: The conversion of Semitic mimation to nunation in the singular. It is best reassessed as a separate language on the Central Semitic dialect continuum. It was also thought that Old Arabic coexisted alongside—and then gradually displaced— epigraphic Ancient North Arabian (ANA), which was theorized to have been the regional tongue for many centuries. ANA, despite its name, was considered a very distinct language, and mutually unintelligible, from "Arabic". Scholars named its variant dialects after
8662-648: The delivery of 3 Bell 505 helicopters to the Royal Bahrain Air Force. Bell delivered the aircraft during an inspection and acceptance event in February 2023 at Bell's Mirabel facility In March 2023, Bahrain has requested the purchase of 24 surplus Bell AH-1W Super Cobra attack helicopters from the US, via a Foreign Military Sales deal worth an estimated US$ 350 million. Arabic language Arabic (endonym: اَلْعَرَبِيَّةُ , romanized : al-ʿarabiyyah , pronounced [al ʕaraˈbijːa] , or عَرَبِيّ , ʿarabīy , pronounced [ˈʕarabiː] or [ʕaraˈbij] )
8784-609: The designation AIM-9E-2 As the Sidewinder was being acquired by NATO forces, licensed production was given to West Germany and they would produce around 15,000 units. Like the Americans, the West Germans sought to improve the AIM-9B design due to its limitations. The only visible exterior difference is a greenish sensor window, but many tech improvements were added beneath the shell. Unnoticed improvements include solid state electronics (instead of vacuum tubes), carbon dioxide seeker cooling,
8906-517: The early AIM-9A & B was that a non-propulsive attachment (NPA) for their MK 15 motor was provided, assuming an assembled missile would be less dangerous to ground crew and material if the rocket motor was ignited. This same NPA was used in the AIM-9B Sidewinder as well. The AIM-9B is very similar to the AIM-9A, but the "B" has a more sophisticated rear and more aerodynamical front fins. The AIM-9B
9028-635: The emergence of Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include: There are several features which Classical Arabic, the modern Arabic varieties, as well as the Safaitic and Hismaic inscriptions share which are unattested in any other Central Semitic language variety, including the Dadanitic and Taymanitic languages of
9150-728: The eve of the conquests: Northern and Central (Al-Jallad 2009). The modern dialects emerged from a new contact situation produced following the conquests. Instead of the emergence of a single or multiple koines, the dialects contain several sedimentary layers of borrowed and areal features, which they absorbed at different points in their linguistic histories. According to Veersteegh and Bickerton, colloquial Arabic dialects arose from pidginized Arabic formed from contact between Arabs and conquered peoples. Pidginization and subsequent creolization among Arabs and arabized peoples could explain relative morphological and phonological simplicity of vernacular Arabic compared to Classical and MSA. In around
9272-593: The fact that they participate in the innovations common to all forms of Arabic. The earliest attestation of continuous Arabic text in an ancestor of the modern Arabic script are three lines of poetry by a man named Garm(')allāhe found in En Avdat, Israel , and dated to around 125 CE. This is followed by the Namara inscription , an epitaph of the Lakhmid king Imru' al-Qays bar 'Amro, dating to 328 CE, found at Namaraa, Syria. From
9394-501: The fourth most useful language for business, after English, Mandarin Chinese , and French. Arabic is written with the Arabic alphabet , an abjad script that is written from right to left . Arabic is usually classified as a Central Semitic language . Linguists still differ as to the best classification of Semitic language sub-groups. The Semitic languages changed between Proto-Semitic and
9516-579: The inclusion of new words into their published standard dictionaries. They also publish old and historical Arabic manuscripts. In 1997, a bureau of Arabization standardization was added to the Educational, Cultural, and Scientific Organization of the Arab League . These academies and organizations have worked toward the Arabization of the sciences, creating terms in Arabic to describe new concepts, toward
9638-469: The internal wiring harnesses. These improvements facilitated a better 100 Hz reticle rate, and a 16.5 deg/sec tracking rate. The most significant design change was the addition of cooling for the PbS detector, adding Peltier (thermoelectric) cooling, giving the advantage of unlimited cooling when positioned on the launch rail, but is only active when electrical power is present. The AIM-9E gives greater range over
9760-608: The language. Software and books with tapes are an important part of Arabic learning, as many of Arabic learners may live in places where there are no academic or Arabic language school classes available. Radio series of Arabic language classes are also provided from some radio stations. A number of websites on the Internet provide online classes for all levels as a means of distance education; most teach Modern Standard Arabic, but some teach regional varieties from numerous countries. The tradition of Arabic lexicography extended for about
9882-400: The last sighting. So if the target remained at 5 degrees left between two rotations of the mirror, the electronics would not output any signal to the control system. Consider a missile fired at right angles to its target; if the missile is flying at the same speed as the target, it should "lead" it by 45 degrees, flying to an impact point far in front of where the target was when it was fired. If
10004-522: The late 1940s, emerging in the early 1950s as a guidance system for the modular Zuni rocket . This modularity allowed for the introduction of newer seekers and rocket motors, including the AIM-9C variant, which used semi-active radar homing and served as the basis of the AGM-122 Sidearm anti-radar missile . Due to the Sidewinder's infrared guidance system, the brevity code " Fox two " is used when firing
10126-599: The late 6th century AD, a relatively uniform intertribal "poetic koine" distinct from the spoken vernaculars developed based on the Bedouin dialects of Najd , probably in connection with the court of al-Ḥīra . During the first Islamic century, the majority of Arabic poets and Arabic-writing persons spoke Arabic as their mother tongue. Their texts, although mainly preserved in far later manuscripts, contain traces of non-standardized Classical Arabic elements in morphology and syntax. Abu al-Aswad al-Du'ali ( c. 603 –689)
10248-420: The latter is taught in formal education settings. However, there have been studies reporting some degree of comprehension of stories told in the standard variety among preschool-aged children. The relation between Modern Standard Arabic and these dialects is sometimes compared to that of Classical Latin and Vulgar Latin vernaculars (which became Romance languages ) in medieval and early modern Europe. MSA
10370-589: The launcher, which the USAF did not use) ATM-9G (USN) : AIM-9G used for captive flight target acquisition training. Within December 1965, two designers McLean and LaBerge (who were employed by Philco-Ford) came together to create ways to improve the AIM-9G's reliability. One submission was to advance all the remaining missile electronic components from vacuum to solid-state gradually. The US Air Force adhered to this steady replacement of their AIM-9s to solid-state, however
10492-476: The launchers, allowing the missile to track any part of the aircraft heated by air resistance due to high speed flight, giving modern Sidewinders all-aspect capabilities. The nose canards provide maneuverability for the AIM-9, with the AIM-9X using thrust vectoring to augment this. The hot gases generated were used to actuate the nose canards in older models, while newer variants use thermal batteries . To minimize
10614-516: The little-used US Navy AIM-9C Sidewinder. This took longer to develop, and did not enter service until 1966. K-13M/R-13M (Object 380) (AA-2D Atoll) : The R-13M is a much improved version of the R-3S and has capabilities similar to the AIM-9G Sidewinder. The R-13M is still a tail engagement missile only but is far more capable than the R-3S due to its new seeker and rocket motor. The new cooled seeker
10736-883: The many national or regional varieties which constitute the everyday spoken language. Colloquial Arabic has many regional variants; geographically distant varieties usually differ enough to be mutually unintelligible , and some linguists consider them distinct languages. However, research indicates a high degree of mutual intelligibility between closely related Arabic variants for native speakers listening to words, sentences, and texts; and between more distantly related dialects in interactional situations. The varieties are typically unwritten. They are often used in informal spoken media, such as soap operas and talk shows , as well as occasionally in certain forms of written media such as poetry and printed advertising. Hassaniya Arabic , Maltese , and Cypriot Arabic are only varieties of modern Arabic to have acquired official recognition. Hassaniya
10858-637: The mid-1980s the air wing became the new Bahrain Amiri Air Force (BAAF). In the early years the Bahraini Air Force participated in training with other countries and helped recover U.S. Navy sailors after the USS Stark incident during the Iran-Iraq War . Because of regional conflicts like the Iran-Iraq War and the Gulf War , during the 1980s and 1990s Bahrain expanded its military with the assistance of
10980-422: The missile automatically got pre-launch instructions. The conical scanning speed was also increased greatly. The seeker head was now able to seek in a 25˚ circular scan. This allowed the AIM-9G to have an improved chance of acquiring the target than earlier models. This, along with other upgraded solid-state modules, culminated in the AIM-9G. The improvement was substantial enough that an order of 5,000 AIM-9D seekers
11102-506: The missile is traveling four times the speed of the target, it should follow an angle about 11 degrees in front. In either case, the missile should keep that angle all the way to interception, which means that the angle that the target makes against the detector is constant. It was this constant angle that the Sidewinder attempted to maintain. This " proportional pursuit " system is straightforward to implement and offers high-performance lead calculation almost for free and can respond to changes in
11224-454: The missile to track aircraft at greater angles from its direct line of sight, or boresight. Models such as the AIM-9L, AIM-9M, and AIM-9X feature high off-boresight capabilities, meaning they are able to track targets at high seeker gimbal angles, or highly distant from its boresight. The Sidewinder is not guided by the actual position recorded by the detector, but by the change in position since
11346-543: The missile was by Grumman F9F-8 Cougars and FJ-3 Furies of the United States Navy in the middle of 1956. Nearly 100,000 of the first generation (AIM-9B/C/D/E) of the Sidewinder were produced with Raytheon and General Electric as major subcontractors. Philco-Ford produced the guidance and control sections of the early missiles. The NATO version of the first-generation missile was built under license in Germany by Bodenseewerk Gerätetechnik ; 9,200 examples were built. AIM-9A
11468-678: The near term, while longer-term plans call for a more capable aircraft to be acquired to add to or replace the F-16 fleet. Bahrain is considering buying the Eurofighter Typhoon , the JAS 39 Gripen , the Dassault Rafale , or the F-35 Lightning II . The British government is in early talks with Bahrain over a potential order for the Eurofighter Typhoon fighter. In September 2016 it was announced that
11590-768: The need for a lexical injection in Arabic, to suit concepts of the industrial and post-industrial age (such as sayyārah سَيَّارَة 'automobile' or bākhirah باخِرة 'steamship'). In response, a number of Arabic academies modeled after the Académie française were established with the aim of developing standardized additions to the Arabic lexicon to suit these transformations, first in Damascus (1919), then in Cairo (1932), Baghdad (1948), Rabat (1960), Amman (1977), Khartum [ ar ] (1993), and Tunis (1993). They review language development, monitor new words and approve
11712-424: The one whose sound is heard but whose person remains unseen. Now the term al-hatif is used for a telephone. Therefore, the process of tawleed can express the needs of modern civilization in a manner that would appear to be originally Arabic. In the case of Arabic, educated Arabs of any nationality can be assumed to speak both their school-taught Standard Arabic as well as their native dialects, which depending on
11834-505: The operation. Bahrain's forces remained in Saudi Arabia in assistance of the coalition through 2015. An RBAF F-16 was lost when it crashed after a technical problem in December 2015. The Bahraini Air Force ended its participation in the operation in Yemen in February 2016. In 2018, Lockheed Martin was awarded a $ 1.1 billion contract to produce 16 F-16 Viper Block 70 fighter aircraft for Bahrain,
11956-458: The original vacuum tubes. The AIM-9H also included a new lead sulphide detector, using nitrogen cooling. The new guidance package was built using semiconductors. When the engineers redesigned these electronics, they essentially kept the AIM-9G's optical system, but the tracking rate increased further, from the original 12˚ to 20˚ degrees per second, this complementing the more powerful 120 lb.ft actuators that had been installed. They also replaced
12078-449: The other 7 were MiG-21s. This was due to the missile design and USN fighter pilot training at TOPGUN . The United States Air Force attempted to attain AIM-9Gs from the USN, due to bad experience with their AIM-9 Sidewinders models (B, E, and J), but they were incompatible with US Air Force's Sidewinder launchers due to the different cooling mechanisms. (the USN used a nitrogen gas container on
12200-549: The overhaul of Arabic grammar first proposed by Al-Jahiz 200 years prior. The Maghrebi lexicographer Ibn Manzur compiled Lisān al-ʿArab ( لسان العرب , "Tongue of Arabs"), a major reference dictionary of Arabic, in 1290. Charles Ferguson 's koine theory claims that the modern Arabic dialects collectively descend from a single military koine that sprang up during the Islamic conquests; this view has been challenged in recent times. Ahmad al-Jallad proposes that there were at least two considerably distinct types of Arabic on
12322-410: The region may be mutually unintelligible. Some of these dialects can be considered to constitute separate languages which may have "sub-dialects" of their own. When educated Arabs of different dialects engage in conversation (for example, a Moroccan speaking with a Lebanese), many speakers code-switch back and forth between the dialectal and standard varieties of the language, sometimes even within
12444-582: The sale of 20 upgrade kits to upgrade Bahrain's existing F-16 fleet to the F-16V Viper variant, the most advanced variant of the F-16, featuring the AN/APG-83 active electronically scanned array radar, a new mission computer developed by Raytheon , modern cockpit displays and other electronics upgrades. In October 2017, Bahraini officials announced that Bahrain had signed a deal worth $ 3.8 billion with Lockheed Martin for upgraded F-16s, as well as upgrade kits for
12566-654: The sale of up to 19 further F-16s had been submitted to the US Congress for approval, however the White House later advised that it would not complete the approval unless it showed progress on human rights issues arising from the Bahraini protests of 2011 . In September 2017, the United States Defense Security Cooperation Agency approved the sale of up to 22 F-16 Block 70 /72 aircraft, as well as
12688-458: The same sentence. The issue of whether Arabic is one language or many languages is politically charged, in the same way it is for the varieties of Chinese , Hindi and Urdu , Serbian and Croatian , Scots and English, etc. In contrast to speakers of Hindi and Urdu who claim they cannot understand each other even when they can, speakers of the varieties of Arabic will claim they can all understand each other even when they cannot. While there
12810-573: The short-range AIM-9M Sidewinder missile and internal cannon through the Gulf War. After the war, the country began to acquire more advanced weapons, including the AIM-7M Sparrow radar-guided air-to-air missile and LANTIRN navigation and targeting pod for air-to-ground weapons that would also be acquired such as the GBU-10/12 laser guided bombs and AGM-65D/G Maverick air-to-ground missiles. In 1994
12932-413: The slewing of the optics through a search pattern to acquire the enemy (most likely using a rosette scan ), it also allowed the slaving of the optics to a radar or helmet sight. This was connected to the onboard computer of the aircraft, which gave the capability of capturing the target using the data coming from the airborne radar. This meant that the target could be locked without being in the sights, and
13054-458: The sole example of Medieval linguist Abu Hayyan al-Gharnati – who, while a scholar of the Arabic language, was not ethnically Arab – Medieval scholars of the Arabic language made no efforts at studying comparative linguistics, considering all other languages inferior. In modern times, the educated upper classes in the Arab world have taken a nearly opposite view. Yasir Suleiman wrote in 2011 that "studying and knowing English or French in most of
13176-556: The standardization of these new terms throughout the Arabic-speaking world, and toward the development of Arabic as a world language . This gave rise to what Western scholars call Modern Standard Arabic. From the 1950s, Arabization became a postcolonial nationalist policy in countries such as Tunisia, Algeria, Morocco, and Sudan. Arabic usually refers to Standard Arabic, which Western linguists divide into Classical Arabic and Modern Standard Arabic. It could also refer to any of
13298-472: The target's flight path, which is much more efficient and makes the missile "lead" the target. During World War II , various researchers in Germany designed infrared guidance systems of various complexity. The most mature development of these, codenamed Hamburg , was intended for use by the Blohm & Voss BV 143 glide bomb in an anti-ship role. Hamburg used a single IR photocell as its detector along with
13420-609: The thermal battery with a turbo-alternator. The AIM-9H also included a continuous-rod bundle warhead, improving its destructive capability. The AIM-9H was the last and most manoeuvrable of the rear-aspect USN Sidewinders, with USN moving to the all-aspect AIM-9L. The AIM-9H was actually used at the very end of the Vietnam war, with it being introduced into the US navy service in 1972 and being used in Operation Linebacker . A total of around 7,700 AIM-9H units would be manufactured from 1972-1974 by Philco-Ford and Raytheon. The AIM-9H
13542-454: The time the war ended. In the immediate post-war era, Allied military intelligence teams collected this information, along with many of the engineers working on these projects. Several lengthy reports on the various systems were produced and disseminated among the Western aircraft firms, while a number of the engineers joined these companies to work on various missile projects. By the late 1940s
13664-501: The towns where the inscriptions were discovered (Dadanitic, Taymanitic, Hismaic, Safaitic). However, most arguments for a single ANA language or language family were based on the shape of the definite article, a prefixed h-. It has been argued that the h- is an archaism and not a shared innovation, and thus unsuitable for language classification, rendering the hypothesis of an ANA language family untenable. Safaitic and Hismaic, previously considered ANA, should be considered Old Arabic due to
13786-451: The world have classes that teach Arabic as part of their foreign languages , Middle Eastern studies , and religious studies courses. Arabic language schools exist to assist students to learn Arabic outside the academic world. There are many Arabic language schools in the Arab world and other Muslim countries. Because the Quran is written in Arabic and all Islamic terms are in Arabic, millions of Muslims (both Arab and non-Arab) study
13908-550: Was a pre-production of the Sidewinder, first fired successfully in September 1953. Missile production began in 1955, and the first models entered the Navy's fleet service in 1956. Generally, it was a prototype production run, with 240 pieces being produced, and mainly intended for training pilots in air combat techniques. The AIM-9A was initially called the AAM-N-7 before the tri-service designation change in 1962. An interesting fact about
14030-453: Was added for the fuze, being the first in the world. This enhanced the missile's head sensitivity. Maneuverability was also improved with a faster tracking rate, as well as a new actuator system. The Sidewinder's range was improved as well, with the new Hercules MK 36 solid-fuel rocket motor allowing the missile to fly up to 18km. Finally, a new Mk 48 continuous-rod warhead was fitted to the missile for increased damage; this also meant infrared or
14152-432: Was famously the first Sidewinder variant to be fired in anger as on 24 September 1958, it achieved the world's first successful kill with a air-to-air missiles, when Taiwanese F-86Fs shot down Communist Chinese MiG-15s using AIM-9Bs supplied and fitted by the U.S. Navy (USN). RB24 : A Swedish AIM-9B Sidewinder. K-13/R-3 (AA-2) : The K-13/R-3 was a reversed engineered AIM-9B Sidewinder, A engagement on 28 September 1958 in
14274-550: Was not present. There were 71 AIM-9E launch attempts from January to October 1972, however, only 6 missiles managed to down an aircraft, with 1 other hitting an aircraft, but not causing complete destruction. Reasons for the poor success rate was listed as "poor air crew training, launches out of the envelope, the tactical situation, marginal tone, tone discrimination, the missile going ballistic, and other malfunctions". AIM-9E : Standard production model. AIM-9E-2 : Some "E" models are equipped with reduced-smoke rocket motors and have
14396-642: Was purchased by the Air Force in 2007 and placed in service with the Bahrain Royal Flight. Bahrain would again engage in combat operations as part of the Saudi Arabia-led Operation Decisive Storm , operating from bases in Saudi Arabia against Houthi rebel forces in Yemen during March and April 2015. Initially, fifteen F-16 aircraft were deployed as the RBAF contribution to combat forces in
14518-515: Was stopped at 1,850 units, with the rest being ordered to AIM-9G seeker specifications instead. Around 2120 AIM-9G were built by Raytheon from 1970 to 1972. The AIM-9G would be used with its predecessor, the AIM-9D, during the Vietnam War, as the US Navy's choice of IR missile. A 46% hit rate with the AIM-9G during Operation Linebackers I and II in 1972 was achieved, of which 14 aircraft were MiG-17s and
14640-491: Was the first version developed solely by the U.S. Air Force (USAF). The AIM-9E allows the expansion of the weapons acquisition envelope, especially at low-altitude, increasing its Probability of Kill (P[k]). It achieved this using a new low-drag conical nose head, being a distinguishing feature of USAF Sidewinders. A magnesium fluoride seeker dome was introduced, along with a more compact optical assembly, an improved guidance control system, new electronics, and significant changes to
14762-441: Was the first version to enter widespread production, in spite of a very long seeker settling time around 22 seconds, as opposed to 11 seconds for the original version. PL-2 : Chinese produced R-3S. A-91 : Romanian produced R-3S. K-13R/R-3R (Object 320) (AA-2B/C Atoll) : While the R-3S was being introduced in 1961, work started on a semi-active radar homing (SARH) version for high-altitude use, with 8 km range, similar to
14884-428: Was the only planned modification. Recognizing the limitations of the initial AIM-9B, the US Navy (USN) worked to improve the missile's performance. They changed the missile nose to an aerodynamical ogival nose. The seeker was improved with a wider field of view beyond 25 degrees and a reduced instantaneous field of view of 2.5 degrees, to reduce foreign thermal interference (from flares). A better nitrogen cooling system
