55-403: The Novator KS-172 was a Russian air-to-air missile project designed as an " AWACS killer" at ranges up to 400 km. The missile had various names during its history, including K-100 , Izdeliye 172 ('project 172'), AAM-L ( RVV-L ), KS–172 , KS-1 , 172S-1 and R-172 . The airframe appears to have been derived from the 9K37 Buk surface-to-air missile (SAM) but development stalled in

110-651: A 360 degree coverage, the radar antenna of the Chinese AWACS does not rotate. Instead, three PAR antenna modules are placed in a triangular configuration inside the round radome to provide a 360 degree coverage. The installation of equipment at the Il-76 began in late 2002 aircraft by Xian aircraft industries (Xian Aircraft Industry Co.). The first flight of an airplane KJ-2000 made in November 2003. All four machines will be equipped with this type. The last to be introduced into service

165-482: A Russian-made Ilyushin-76 cargo plane [also incorrectly reported as a Beriev A-50 Mainstay] with advanced Elta electronic, computer, radar and communications systems. Beijing was expected to acquire several Phalcon AEW systems, and reportedly could buy at least three more [and possibly up to eight] of these systems, the prototype of which was planned for testing beginning in 2000. In July 2000, the US pressured Israel to back out of

220-503: A different installation was used to direct Bristol Beaufighters toward Heinkel He 111s , which were air-launching V-1 flying bombs . In February 1944, the US Navy ordered the development of a radar system that could be carried aloft in an aircraft under Project Cadillac. A prototype system was built and flown in August on a modified TBM Avenger torpedo bomber . Tests were successful, with

275-474: A major advance in capability, being the first AEW to use a pulse-Doppler radar , which allowed it to track targets normally lost in ground clutter. Previously, low-flying aircraft could only be readily tracked over water. The AWACS features a three-dimensional radar that measures azimuth, range, and elevation simultaneously; the unit installed upon the E-767 has superior surveillance capability over water compared to

330-487: A major asset in an AEW aircraft. Following a crash, the US Navy opted to discontinue lighter than air operations in 1962. In 1958, the Soviet Tupolev Design Bureau was ordered to design an AEW aircraft. After determining that the projected radar instrumentation would not fit in a Tupolev Tu-95 or a Tupolev Tu-116 , the decision was made to use the more capacious Tupolev Tu-114 instead. This solved

385-592: A maximum range of over 850 km at 9,000 metres (30,000 ft) altitude. The Swedish Air Force uses the S 100D Argus ASC890 as its AEW platform. The S 100D Argus is based on the Saab 340 with an Ericsson Erieye PS-890 radar. Saab also offers the Bombardier Global 6000 -based GlobalEye . In early 2006, the Pakistan Air Force ordered six Erieye AEW equipped Saab 2000s from Sweden. In December 2006,

440-603: A modified version being shown at the 2007 Moscow Air Show designated as the K-100-1. This name first appeared in a Sukhoi document in 2006, and sources such as Jane's now refer to the missile as the K-100. Nowadays the missile is not in commission whether in Russia nor in India. Supposedly the development was stopped and the project closed by 2010. The mockup shown in 1993 had a strong resemblance to

495-476: A pseudorandom set of frequencies and also have very short scanning rates, which makes them difficult to detect and jam. Up to 1000 targets can be tracked simultaneously to a range of 243 mi (450 km), while at the same time, multitudes of air-to-air interceptions or air-to-surface (including maritime) attacks can be guided simultaneously. The radar equipment of the Israeli AEW&;C consists of each L-band radar on

550-522: A range of up to 400 km (220 nmi), and there have been persistent rumours – if little hard evidence – of an air-to-air missile with a range of 200 km (110 nmi) based on Zvezda's Kh-31 anti-radar/anti-shipping missile or its Chinese derivative, the YJ-91 . NPO Novator started work in 1991 on a very long-range air-to-air missile with the Russian project designation Izdeliye 172 . Initially called

605-444: A significant effect on fighting capability, and they are usually heavily defended by fighter escorts. A long-range air-to-air missile offers the prospect of bringing down the target without having to fight a way through the fighter screen. Given the potential importance of "blinding" Western AWACS, Russia has devoted considerable resources to this area. The R-37 (missile) (AA-13 'Arrow') is an evolution of their R-33 (AA-9 'Amos') with

660-645: A substantial AEW capability, initially with American Douglas AD-4W Skyraiders , designated Skyraider AEW.1, which in turn were replaced by the Fairey Gannet AEW.3 , using the same AN/APS-20 radar. With the retirement of conventional aircraft carriers, the Gannet was withdrawn and the Royal Air Force (RAF) installed the radars from the Gannets on Avro Shackleton MR.2 airframes, redesignated Shackleton AEW.2. To replace

715-512: Is an airborne radar early warning system designed to detect aircraft , ships , vehicles , missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack aircraft . AEW&C units are also used to carry out aerial surveillance over ground and maritime targets , and frequently perform battle management command and control (BMC2). When used at altitude,

770-511: Is an important event for the Russian aviation industry and the Commonwealth of Independent States . Although it started mainly as an entertainment event, the show soon became a marketplace where Russian aerospace companies could negotiate export contracts and Russian air carriers could make foreign contacts. The 2023 MAKS event was scheduled for July 25-30, 2023, but has been postponed to 2024, allegedly because of security concerns. In June 2024,

825-636: Is by inertial navigation until the missile is close enough to the target to use active radar for terminal homing. The K-100 has an enlarged (350 mm (14 in)) derivative of the Agat 9B-1103M seeker used in the R-27 (air-to-air missile) (AA-10 'Alamo'). It has a lock-on range of 40 km (22 nmi), described by an Agat designer as "one fifth or less of the overall range". [REDACTED] [REDACTED] Airborne Early Warning and Control An airborne early warning and control ( AEW&C ) system

880-525: Is considered to be both more capable and less expensive to operate than the older Boeing 707-based Phalcon fleet. In 2017, India announced plans to purchase six airborne early warning and control (AEW&C) ("AWACS") aircraft that can also perform aerial refuelling, with the first two AEW&C aircraft awaiting approval by Cabinet in 2020. However, in September 2021, it was decided to use six Airbus A321s acquired from Air India instead. On 3 June 1957,

935-483: Is currently in service with Israel, Italy, and Singapore. Instead of using a rotodome, a moving radar was found on some AEW&C aircraft, and the EL/W-2085 used an active electronically scanned array (AESA) – an active phased array radar. This radar consists of an array of transmit/receive (T/R) modules that allow a beam to be electronically steered, making a physically rotating rotodome unnecessary. AESA radars operate on

990-610: Is the home of the Gromov Flight Research Institute . After the dissolution of the Soviet Union , many aviation companies eventually moved to Zhukovsky, using the Gromov Flight Research Institute's airfield for MosAeroShow-92 held on 11–16 August 1992. A second show was held in 1993, now renamed MAKS. Since then the air show has been held biannually. It lasts for six days, three of which are open to

1045-741: The Indian Air Force (IAF) and Defence Research and Development Organisation (DRDO) began a study of requirements for developing an Airborne Early Warning and Control (AWAC) system. In 2015, DRDO delivered 3 AWACs, called Netra , to the IAF with an advanced Indian AESA radar system fitted on the Brazilian Embraer EMB-145 air frame. Netra gives a 240-degree coverage of airspace. The Emb-145 also has air-to-air refuelling capability for longer surveillance time. The IAF also operates three Israeli EL/W-2090 systems, mounted on Ilyushin Il-76 airframes,

1100-637: The Italian Navy is operated from the aircraft carriers Cavour and Giuseppe Garibaldi . During the 2010s, the Royal Navy opted to replace its Sea Kings with a modular "Crowsnest" system that can be fitted to any of their Merlin HM2 fleet. The Crowsnest system was partially based upon the Sea King ASaC7's equipment; an unsuccessful bid by Lockheed Martin had proposed using a new multi-functional sensor for either

1155-518: The Pakistan Navy requested three excess P-3 Orion aircraft to be equipped with Hawkeye 2000 AEW systems. China and Pakistan also signed a memorandum of understanding (MoU) for the joint development of AEW&C systems. The Hellenic Air Force , Brazilian Air Force and Mexican Air Force use the Embraer R-99 with an Ericsson Erieye PS-890 radar, as on the S 100D. Israel has developed

1210-675: The Thorn-EMI ARI 5980/3 Searchwater LAST radar attached to the fuselage on a swivel arm and protected by an inflatable dome. The improved Sea King ASaC7 featured the Searchwater 2000AEW radar, which was capable of simultaneously tracking up to 400 targets, instead of an earlier limit of 250 targets. The Spanish Navy fields the SH-3 Sea King in the same role, operated from the LPH Juan Carlos I . The AgustaWestland EH-101A AEW of

1265-479: The Turkish Air Force are deploying Boeing 737 AEW&C aircraft. The Boeing 737 AEW&C has a fixed, active electronically scanned array radar antenna instead of a mechanically-rotating one, and is capable of simultaneous air and sea search, fighter control and area search, with a maximum range of over 600 km (look-up mode). In addition, the radar antenna array is also doubled as an ELINT array, with

1320-562: The United States Navy , the Northrop Grumman E-2 Hawkeye AEW&;C aircraft is assigned to its supercarriers to protect them and augment their onboard command information centers (CICs). The designation "airborne early warning" (AEW) was used for earlier similar aircraft used in the less-demanding radar picket role, such as the Fairey Gannet AEW.3 and Lockheed EC-121 Warning Star , and continues to be used by

1375-508: The $ 1 billion agreement to sell China four Phalcon phased-array radar systems. Following the cancelled A-50I/Phalcon deal, China turned to indigenous solutions. The Phalcon radar and other electronic systems were taken off from the unfinished Il-76, and the airframe was handed to China via Russia in 2002. The Chinese AWACS has a unique phased array radar (PAR) carried in a round radome. Unlike the US AWACS aircraft, which rotate their rotodomes to give

1430-602: The 1930s, the British developed a radar set that could be carried on an aircraft for what they termed "Air Controlled Interception". The intention was to cover the North West approaches where German long range Focke-Wulf Fw 200 Condor aircraft were threatening shipping. A Vickers Wellington bomber (serial R1629) was fitted with a rotating antenna array. It was tested for use against aerial targets and then for possible use against German E boats . Another radar equipped Wellington with

1485-714: The AAM-L (RVV-L), it made its first public appearance at the International Defence Exhibition in Abu Dhabi in early 1993, followed by the Moscow Air Show later that year. It was described as having a range of 400 km (220 nmi); the mockup on display had a strong resemblance to the 9K37M1 Buk-M (SA-11 'Gadfly'). Apparently some flight-testing was done on a Su-27, but it appears that the Russians withdrew funding for

1540-721: The AEW role. The "Mainstay" is based on the Ilyushin Il-76 airframe, with a large non-rotating disk radome on the rear fuselage. These replaced the 12 Tupolev Tu-126 that filled the role previously. The A-50 and A-50U will eventually be replaced by the Beriev A-100 , which features an AESA array in the radome and is based on the updated Il-476. In May 1997, Russia and Israel agreed to jointly fulfill an order from China to develop and deliver an early warning system. China reportedly ordered one Phalcon for $ 250 million, which entailed retrofitting

1595-498: The AN/APY-1 system on the earlier E-3 models. The E-2 Hawkeye was a specially designed AEW aircraft. Upon its entry to service in 1965, it was initially plagued by technical issues, causing a (later reversed) cancellation. Procurement resumed after efforts to improve reliability, such as replacement of the original rotary drum computer used for processing radar information by a Litton L-304 digital computer. In addition to purchases by

1650-712: The AW101 or another aircraft. The Russian-built Kamov Ka-31 is deployed by the Indian Navy on the aircraft carriers INS  Vikramaditya and INS  Vikrant and also on Talwar -class frigates . The Russian Navy has two Ka-31R variants, at least one of which was deployed on their aircraft carrier Admiral Kuznetsov in 2016. It is fitted with E-801M Oko (Eye) airborne electronic warfare radar that can track 20 targets simultaneously, detecting aircraft up to 150 km (90 mi) away, and surface warships up to 200 km (120 mi) distant.

1705-688: The Buk airframe, but since the Indians became involved there have been some changes. An Indian magazine gave the specifications of the KS–172 in April 2004 as a core 6.01 m long and 40 cm in diameter with a wingspan of 61 cm, with a booster of 1.4 m, and 748 kg total weight. It had a solid fuel tandem rocket booster capable of speeds up to 4,000 km/h (2,500 mph), 12g manoeuvring, and an adaptive HE fragmentation warhead. Development would concentrate on

1760-505: The Chinese Air Force until the end of 2007. China is also developing a carrier-based AEW&C, Xian KJ-600 via Y-7 derived Xian JZY-01 testbed. The EL/W-2085 is an airborne early warning and control (AEW&C) multi-band radar system developed by Israel Aerospace Industries (IAI) and its subsidiary Elta Systems of Israel. Its primary objective is to provide intelligence to maintain air superiority and conduct surveillance. The system

1815-550: The Engineering Show by TsAGI in 1990. The objective of the MAKS air show is to demonstrate leading technologies and to open up the Russian aerospace industry to the international market. A large portion of the show is dedicated to holding scientific conferences and symposia, under the auspices of Russia's Central Aerohydrodynamic Institute. The air show is held in the city of Zhukovsky , at Zhukovsky International Airport , which

1870-555: The IAI/Elta EL/M-2075 Phalcon system, which uses an AESA ( active electronically scanned array ) in lieu of a rotodome antenna. The system was the first such system to enter service. The original Phalcon was mounted on a Boeing 707 and developed for the Israeli Defense Force and for export. Israel uses IAI EL/W-2085 airborne early warning and control multi-band radar system on Gulfstream G550 ; this platform

1925-823: The RAF for its Sentry AEW1 , while AEW&C (airborne early warning and control) emphasizes the command and control capabilities that may not be present on smaller or simpler radar picket aircraft. AWACS (Airborne Warning and Control System) is the name of the specific system installed in the E-3 and Japanese Boeing E-767 AEW&C airframes, but is often used as a general synonym for AEW&C. Modern AEW&C systems can detect aircraft from up to 400 km (220 nmi) away, well out of range of most surface-to-air missiles. One AEW&C aircraft flying at 9,000 m (30,000 ft) can cover an area of 312,000 km (120,000 sq mi). Three such aircraft in overlapping orbits can cover

1980-542: The S-bands. Historically, UHF radars had resolution and detection issues that made them ineffective for accurate targeting and fire control; Northrop Grumman and Lockheed claim that the APY-9 has solved these shortcomings in the APY-9 using advanced electronic scanning and high digital computing power via space/time adaptive processing. The Russian Aerospace Forces are currently using approximately 3-5 Beriev A-50 and A-50U "Shmel" in

2035-685: The Shackleton AEW.2, an AEW variant of the Hawker Siddeley Nimrod , known as the Nimrod AEW3 , was ordered in 1974. After a protracted and problematic development, this was cancelled in 1986, and seven E-3Ds, designated Sentry AEW.1 in RAF service, were purchased instead. Many countries have developed their own AEW&C systems, although the Boeing E-3 Sentry , E-7A and Northrop Grumman E-2 Hawkeye and Gulfstream/IAI EL/W-2085 are

2090-526: The US Navy, the E-2 Hawkeye has been sold to the armed forces of Egypt , France , Israel , Japan , Singapore and Taiwan . The latest E-2 version is the E-2D Advanced Hawkeye , which features the new AN/APY-9 radar. The APY-9 radar has been speculated to be capable of detecting fighter-sized stealth aircraft, which are typically optimized against high frequencies like Ka, Ku, X, C and parts of

2145-432: The consequence of lessons learnt by the Royal Navy during the 1982 Falklands War when the lack of AEW coverage for the task force was a major tactical handicap, and rendered them vulnerable to low-level attack. The Sea King was determined to be both more practical and responsive than the proposed alternative of relying on the RAF's land-based Shackleton AEW.2 fleet. The first examples were a pair of Sea King HAS2s that had

2200-573: The first of 2 HR2S-1W, a derivative of the Sikorsky CH-37 Mojave , was delivered to the US Navy, it used the AN/APS-32 but proved unreliable due to vibration. The British Sea King ASaC7 naval helicopter was operated from both the Invincible -class aircraft carriers and later the helicopter carrier HMS  Ocean . The creation of Sea King ASaC7, and earlier AEW.2 and AEW.5 models, came as

2255-708: The first of which first arrived on 25 May 2009. The DRDO proposed a more advanced AWACS with a longer range and with a 360-degree coverage akin to the Phalcon system, based on the Airbus A330 airframe, but given the costs involved there is also the possibility of converting used A320 airliners as well. IAF has plans to develop 6 more Netra AEW&CS based on Embraer EMB-145 platform and another 6 based on Airbus A321 platform. These systems are expected to have an enhanced performance including range and azimuth The Royal Australian Air Force , Republic of Korea Air Force and

2310-792: The government of the Russian Federation announced that it would be further postponed to 2025. In July 2024, the show's organisers announced that an online version would be held instead. The air show's history traces back to 1911, when one was held in Mikhailovskiy Square in Saint Petersburg . The Soviet Union held annual air shows on the Tushino Airfield in Moscow 22 years later. Its history in Zhukovskiy, however, began much later with

2365-480: The left and right sides of the fuselage and each S-band antenna in the nose and tail. The phased array allows aircraft positions on operator screens to be updated every 2–4 seconds rather than every 10 seconds, as is the case on the rotodome AWACS. ELTA was the first company to introduce an Active Electronically Scanned Array Airborne (AESA) Early Warning Aircraft and implement advanced mission aircraft using efficient, high-performance business jet platforms. In 2003,

2420-732: The mid-1990s for lack of funds. It appears to have restarted in 2004 after a deal with India, who wants to produce the missile in India for their Su-30MKI fighters. Development has ceased and the project is closed. Modern air forces have become dependent on airborne radars typically carried by converted airliners and transport aircraft such as the E-3 Sentry and A-50 'Mainstay' . They also depend on similar aircraft for inflight refuelling (e.g. Vickers VC10 ), maritime patrol (e.g. CP-140 Aurora ), reconnaissance and electronic warfare (e.g. Tu-16 'Badger' E & J) and C4ISTAR (e.g. VC-25 "Air Force One" ). The loss of just one of these aircraft can have

2475-405: The model shown at the 2007 MAKS airshow under the name K-100 was closer to the original 1993 mockup in the photo above, with different-shaped fins that were further up the fuselage, and an even larger booster with TVC vents. At the same show it was shown under the wing of a Su-35BM, implying that at least two could be carried by Flanker-class aircraft rather than just one on the centreline. Guidance

2530-534: The most common systems worldwide. Boeing produces a specific system with a " rotodome " rotating radome that incorporates Westinghouse (now Northrop Grumman ) radar. It is mounted on either the E-3 Sentry aircraft ( Boeing 707 ) or more recently the Boeing E-767 ( Boeing 767 ), the latter only being used by the Japan Air Self-Defense Force . When AWACS first entered service it represented

2585-629: The problems with cooling and operator space that existed with the narrower Tu-95 and Tu-116 fuselage. To meet range requirements, production examples were fitted with an air-to-air refueling probe. The resulting system, the Tupolev Tu-126 , entered service in 1965 with the Soviet Air Forces and remained in service until replaced by the Beriev A-50 in 1984. During the Cold war, United Kingdom deployed

2640-454: The project and to be "negotiating a partnership" to develop the "R-172". In May 2005 the Indians were said to have finalised "an arrangement to fund final development and licence produce the weapon" in a joint venture similar to that which produced the successful BrahMos cruise missile. Since then the missile has had a higher profile, appearing at the 2005 Moscow Air Show on a Su-30 as the K-172, and

2695-429: The project soon afterwards. The missile resurfaced as the KS–172 in 1999, as part of a new export-led strategy whereby foreign investment in a 300 km (160 nmi)-range export model would ultimately fund a version for the Russian airforce. Again it appears that there were no takers. In late 2003, the missile was offered again on the export market as the 172S-1. In March 2004, India was reported to have invested in

2750-540: The radar system on AEW&C aircraft allows the operators to detect, track and prioritize targets and identify friendly aircraft from hostile ones in real-time and from much farther away than ground-based radars. Like ground-based radars, AEW&C systems can be detected and targeted by opposing forces, but due to aircraft mobility and extended sensor range, they are much less vulnerable to counter-attacks than ground systems. AEW&C aircraft are used for both defensive and offensive air operations, and serve air forces in

2805-553: The same radar. The Lockheed WV and EC-121 Warning Star , which first flew in 1949, served widely with US Air Force and US Navy. It provided the main AEW coverage for US forces during the Vietnam war. It remained operational until replaced with the E-3 AWACS. Developed roughly in parallel, N-class blimps were also used as AEW aircraft, filling gaps in radar coverage for the continental US, their tremendous endurance of over 200 hours being

2860-410: The same role as what the combat information center is to naval warships , in addition to being a highly mobile and powerful radar platform. So useful and advantageous is it to have such aircraft operating at a high altitude, that some navies also operate AEW&C aircraft for their warships at sea, either coastal- or carrier-based and on both fixed-wing and rotary-wing platforms. In the case of

2915-431: The seeker head, autopilot, resistance to jamming and a steering system with 3D thrust vector control (TVC). In May 2005 it was reported that there were two versions, with and without a rocket booster, with ranges of 400 km and 300 km respectively. At the MAKS (air show) in August 2005, a range of 300 km was quoted for a streamlined missile with a small booster and fins on both booster and fuselage. However

2970-497: The system being able to detect low flying formations at a range greater than 100 miles (160 km). US Navy then ordered production of the TBM-3W, the first production AEW aircraft to enter service. TBM-3Ws fitted with the AN/APS-20 radar entered service in March 1945, with 27 eventually constructed. It was also recognised that a larger land-based aircraft would be attractive, thus, under the Cadillac II program, multiple Boeing B-17G Flying Fortress bombers were also outfitted with

3025-517: The whole of Central Europe . AEW&C system indicates close and far proximity range on threats and targets, help extend the range of their sensors, and make offensive aircraft harder to track by avoiding the need for them to keep their own radar active, which the enemy can detect. Systems also communicate with friendly aircraft, vectoring fighters towards hostile aircraft or any unidentified flying object. After having developed Chain Home —the first ground-based early-warning radar detection system—in
