9625-532: The captain asked for a status of the original target identifier TN4474, the Aegis system had recycled that identifier to a different target which was descending, indicating possible attack posture. An article by David Pogue in Scientific American rated it as one of the five "worst digital user-interface debacles of all time." Poland – in Europe  (green & dark grey) – in

9750-659: The conversion of a pagan ruler of the Polans to Christianity, under the auspices of the Roman Catholic Church in 966. The Kingdom of Poland emerged in 1025, and in 1569 cemented its long-standing association with Lithuania , thus forming the Polish–Lithuanian Commonwealth . At the time, the Commonwealth was one of the great powers of Europe, with an elective monarchy and a uniquely liberal political system, which adopted Europe's first modern constitution in 1791. With

9875-403: The decades up until World War I , a new political tradition was established in the country. Many exiled Polish activists, such as Ignacy Jan Paderewski , who would later become prime minister, returned home. A significant number of them then went on to take key positions in the newly formed political and governmental structures. Tragedy struck in 1922 when Gabriel Narutowicz , inaugural holder of

10000-552: The demand for craft labour spurred a migration of German and Flemish settlers into Poland, which was encouraged by the Polish dukes. In 1264, the Statute of Kalisz introduced unprecedented autonomy for the Polish Jews , who came to Poland fleeing persecution elsewhere in Europe. In 1320, Władysław I the Short became the first king of a reunified Poland since Przemysł II in 1296, and

10125-538: The doctrine of the so-called Polish Brethren , who separated from their Calvinist denomination and became the co-founders of global Unitarianism .

Construction is to begin in the following year of FY2024. At 20,000 tons each, both vessels will be

10375-686: The earliest evidence of European cheesemaking (5500 BC) was discovered in Polish Kuyavia , and the Bronocice pot is incised with the earliest known depiction of what may be a wheeled vehicle (3400 BC). The period spanning the Bronze Age and the Early Iron Age (1300 BC–500 BC) was marked by an increase in population density, establishment of palisaded settlements ( gords ) and the expansion of Lusatian culture . A significant archaeological find from

10500-530: The elections organised by the occupying Soviet authorities were falsified and were used to provide a veneer of legitimacy for Soviet hegemony over Polish affairs. The Soviet Union instituted a new communist government in Poland, analogous to much of the rest of the Eastern Bloc . As elsewhere in Communist Europe , the Soviet influence over Poland was met with armed resistance from the outset which continued into

10625-497: The first King of Poland in c.  1025 , when Bolesław received permission for his coronation from Pope John XIX . Bolesław also expanded the realm considerably by seizing parts of German Lusatia , Czech Moravia , Upper Hungary , and southwestern regions of the Kievan Rus' . The transition from paganism in Poland was not instantaneous and resulted in the pagan reaction of the 1030s . In 1031, Mieszko II Lambert lost

10750-449: The first 28 ships (DDGs 51–78) of the U.S. Navy's Arleigh Burke -class destroyers. This capability is also incorporated in USS  John Finn  (DDG-113) and following new construction, as well as Aegis Ashore. MMSP modifies transmitters of the SPY-1D radar to enable dual-beam operation for reduced frame times and better reaction time, and provides stability for all waveforms , allowing

10875-625: The first elected king, approbated the Henrician Articles which obliged future monarchs to respect the rights of nobles. When he left Poland to become King of France , his successor, Stephen Báthory , led a successful campaign in the Livonian War , granting Poland more lands across the eastern shores of the Baltic Sea. State affairs were then headed by Jan Zamoyski , the Crown Chancellor . Stephen's successor, Sigismund III , defeated

In 1364, Casimir inaugurated

11125-516: The gas turbine powered Spruance class . When the CSGN was cancelled, the Navy proposed a modified Virginia -class design (CGN 42) with a new superstructure designed for the Aegis Combat System and with a displacement of 12,100 tons. As compared to the CSGN, this design was not as survivable and had reduced command and control facilities for an embarked flag officer. Ultimately this design was also cancelled during

11250-635: The genocidal Generalplan Ost . Poland made the fourth-largest troop contribution in Europe, and its troops served both the Polish Government in Exile in the west and Soviet leadership in the east . Polish troops played an important role in the Normandy , Italian , North African Campaigns and Netherlands and are particularly remembered for the Battle of Britain and Battle of Monte Cassino . Polish intelligence operatives proved extremely valuable to

11375-592: The horizon, and sometimes beyond this due to anomalous propagation — instrumented range has been measured at 450 kilometres (280 mi). Typical detection range against fighter-sized targets is approximately 425 kilometres (264 mi), in a 150° broadside sector, both sides of the aircraft. Outside these sectors, performance is reduced in forward and aft directions. Other system features include: Adaptive waveform generation (including digital, phase-coded pulse compression); Signal processing and target tracking; track while scan (TWS); low side lobe values (throughout

11500-473: The island of Ōshima , which lies 30 miles (48 km) west of the main island of Hokkaido . Two additional ICBMs were subsequently launched on 20 February 2023, with both landing in the Sea of Japan off the east coast of the Korean Peninsula . On 19 December 2023, United States, Japan, and South Korea announced the activation of a real-time North Korea missile warning system as well as jointly established

11625-514: The largest surface combatant warships operated by the JMSDF, and according to Popular Mechanics , they will "arguably [be] the largest deployable surface warships in the world.".

11750-405: The late 1960s, the U.S. Navy recognized that reaction time, firepower, and operational availability in all environments did not match the anti-ship missile threat. The new threat of Soviet anti-ship missiles exposed a weakness in contemporary naval radar. The requirements of both tracking and targeting these missiles was limited by the number of radars on each ship, which was typically 2–4. In 1958

11875-542: The navy started the Typhon Combat System , a prophetic program culminating in the futuristic but unreliable AN/SPG-59 phased array radar, which was never made viable and was cancelled in 1963 to be replaced by the Advanced Surface Missile System (ASMS). As a result, the U.S. Navy decided to develop a program to defend ships from anti-ship missile threats. An Advanced Surface Missile System (ASMS)

12000-426: The new Prime Minister leading a coalition made up of Civic Coalition , Third Way , and The Left . Law and Justice became the leading opposition party.

Poland regained its independence at the end of World War I in 1918 with the creation of the Second Polish Republic , which emerged victorious in various conflicts of the interbellum period. In September 1939, the invasion of Poland by Germany and the Soviet Union marked

12500-484: The period known as Golden Liberty , when the state was ruled by the seemingly free and equal Polish nobles . The 16th century saw Protestant Reformation movements making deep inroads into Polish Christianity, which resulted in the establishment of policies promoting religious tolerance, unique in Europe at that time. This tolerance allowed the country to avoid the religious turmoil and wars of religion that beset Europe. In Poland, Nontrinitarian Christianity became

12625-563: The population to private manorial farmstead known as folwarks . In 1493, John I Albert sanctioned the creation of a bicameral parliament composed of a lower house, the Sejm , and an upper house, the Senate . The Nihil novi act adopted by the Polish General Sejm in 1505, transferred most of the legislative power from the monarch to the parliament, an event which marked the beginning of

12750-473: The presence of Roman Legions sent to protect the amber trade . The Polish tribes emerged following the second wave of the Migration Period around the 6th century AD; they were Slavic and may have included assimilated remnants of peoples that earlier dwelled in the area. Beginning in the early 10th century, the Polans would come to dominate other Lechitic tribes in the region, initially forming

12875-621: The presidency, was assassinated at the Zachęta Gallery in Warsaw by a painter and right-wing nationalist Eligiusz Niewiadomski . In 1926, the May Coup , led by the hero of the Polish independence campaign Marshal Józef Piłsudski , turned rule of the Second Polish Republic over to the nonpartisan Sanacja ( Healing ) movement to prevent radical political organisations on both the left and

13000-515: The protohistory of Poland is a fortified settlement at Biskupin , attributed to the Lusatian culture of the Late Bronze Age (mid-8th century BC). Throughout antiquity (400 BC–500 AD), many distinct ancient populations inhabited the territory of present-day Poland, notably Celtic , Scythian , Germanic , Sarmatian , Baltic and Slavic tribes. Furthermore, archaeological findings confirmed

13125-601: The radar system to detect, track, and support engagements of a broader range of threats. MMSP improves performance in littoral , ducted clutter , electronic attack (EA), and chaff environments and provides greater commonality in computer programs and equipment. As of April 2022, the U.S. and Japan are the only countries to purchase or deploy the Aegis BMD on their military ships. Flight III of Arleigh Burke -class destroyers starting with USS  Jack H. Lucas are equipped with AN/SPY-6 AESA radar from Raytheon , which

13250-494: The right from destabilizing the country. By the late 1930s, due to increased threats posed by political extremism inside the country, the Polish government became increasingly heavy-handed, banning a number of radical organisations, including communist and ultra-nationalist political parties, which threatened the stability of the country. World War II began with the Nazi German invasion of Poland on 1 September 1939, followed by

13375-529: The strike version, thus incorporating anti-submarine warfare (ASW) systems and Tomahawk Land Attack Cruise Missiles (TLAM). Shipboard torpedo and naval gunnery systems are also integrated. AWS, the heart of Aegis, comprises the AN/SPY-1 Radar, MK 99 Fire Control System, Weapon Control System (WCS), the Command and Decision Suite, and Standard Missile family of weapons; these include the basic RIM-66 Standard ,

13500-619: The summer of 1944 it initiated Operation Tempest , of which the Warsaw Uprising that began on 1 August 1944 is the best-known operation. Nazi German forces under orders from Adolf Hitler set up six German extermination camps in occupied Poland, including Treblinka , Majdanek and Auschwitz . The Germans transported millions of Jews from across occupied Europe to be murdered in those camps. Altogether, 3 million Polish Jews – approximately 90% of Poland's pre-war Jewry – and between 1.8 and 2.8 million ethnic Poles were killed during

13625-472: The system's angular coverage); low- and medium- pulse repetition frequency operating modes; frequency agility ; Air-to-air and sea surveillance modes; and target radar cross-section display. The radar operates as a medium- to high-PRF pulse-Doppler, solid-state radar, in E/F-band (3 GHz), incorporating 192 two-way transmit/receive modules that combine to produce a pencil beam, steered as required within

13750-468: The system's recorded target data contributed to the investigation of the incident. The discrepancies between the Aegis data report and what the ship's personnel reported to the commanding officer are as follows: Other analyses found that ineffective user interface design caused poor integration with the crisis management human processes it was intended to facilitate. The Aegis System software shuffles target tracking numbers as it gathers additional data. When

13875-603: The time. In the Baltic Sea region, the struggle of Poland and Lithuania with the Teutonic Knights continued and culminated at the Battle of Grunwald in 1410, where a combined Polish-Lithuanian army inflicted a decisive victory against them. In 1466, after the Thirteen Years' War , king Casimir IV Jagiellon gave royal consent to the Peace of Thorn , which created the future Duchy of Prussia under Polish suzerainty and forced

14000-612: The title of king and fled amidst the violence. The unrest led to the transfer of the capital to Kraków in 1038 by Casimir I the Restorer . In 1076, Bolesław II re-instituted the office of king, but was banished in 1079 for murdering his opponent, Bishop Stanislaus . In 1138, the country fragmented into five principalities when Bolesław III Wrymouth divided his lands among his sons. These were Lesser Poland , Greater Poland, Silesia , Masovia and Sandomierz , with intermittent hold over Pomerania . In 1226, Konrad I of Masovia invited

14125-536: The unemployment rate increased. Poland became a member of the Visegrád Group in 1991, and joined NATO in 1999. Poles then voted to join the European Union in a referendum in June 2003, with Poland becoming a full member on 1 May 2004, following the consequent enlargement of the organisation . Poland has joined the Schengen Area in 2007, as a result of which, the country's borders with other member states of

14250-528: The vast Commonwealth began declining from internal disorder and constant warfare. In 1648, the Polish hegemony over Ukraine sparked the Khmelnytsky Uprising , followed by the decimating Swedish Deluge during the Second Northern War , and Prussia's independence in 1657. In 1683, John III Sobieski re-established military prowess when he halted the advance of an Ottoman Army into Europe at

Poniatowski was the head figure of the Enlightenment , encouraged the development of industries, and embraced republican neoclassicism . For his contributions to the arts and sciences he was awarded

14750-508: Was extensively funded by his sponsor and former lover, Empress Catherine II of Russia . The new king maneuvered between his desire to implement necessary modernising reforms, and the necessity to remain at peace with surrounding states. His ideals led to the formation of the 1768 Bar Confederation , a rebellion directed against the Poniatowski and all external influence, which ineptly aimed to preserve Poland's sovereignty and privileges held by

14875-582: Was formally designated to perform type-command administrative oversight for the four BMD-capable destroyers based at Rota, Spain. The Japanese Maritime Self Defense Force (JMSDF) currently operates four Kongō , two Atago , and two Maya -class guided-missile destroyers as part of its "Aegis Afloat" program ( See table below ). Additionally, on 31 August 2022, The Japan Ministry of Defense announced that JMSDF will operate two " Aegis system equipped ships " (イージス・システム搭載艦 in Japanese) ( pictured to replace

15000-437: Was installed in a test ship, USS  Norton Sound , in 1973. During this time frame, the Navy envisioned installing the Aegis Combat System on both a nuclear-powered " strike cruiser " (or CSGN) and a conventionally-powered destroyer (originally designated DDG 47). The CSGN was to be a new, 17,200 ton cruiser design based on the earlier California and Virginia -class cruisers. The Aegis destroyer design would be based on

15125-596: Was promulgated and an engineering development program was initiated in 1964 to meet the requirements. ASMS was renamed "Aegis" in December 1969 after the aegis , the shield of the Greek god Zeus . The name was suggested by Captain L. J. Stecher, a former Tartar Weapon System manager, after an internal U.S. Navy contest to name the ASMS program was initiated. Captain Stecher also submitted

15250-481: Was re-elected in the 2020 presidential election . As of November 2023 , the Russian invasion of Ukraine had led to 17 million Ukrainian refugees crossing the border to Poland. As of November 2023 , 0.9 million of those had stayed in Poland. In October 2023, the ruling Law and Justice (PiS) party won the largest share of the vote in the election , but lost its majority in parliament. In December 2023, Donald Tusk became

15375-667: Was the buckler (shield) of Zeus, worn by Athena. The Aegis Combat System (ACS) implements advanced command and control (command and decision, or C&D, in Aegis parlance). It is composed of the Aegis Weapon System (AWS), the fast-reaction component of the Aegis Anti-Aircraft Warfare (AAW) capability, along with the Phalanx Close In Weapon System (CIWS) , and the Mark 41 Vertical Launch System . Mk 41 VLS

15500-447: Was to become Poland approximately 500,000 years ago, though the ensuing hostile climate prevented early humans from founding more permanent encampments. The arrival of Homo sapiens and anatomically modern humans coincided with the climatic discontinuity at the end of the Last Glacial Period ( Northern Polish glaciation 10,000 BC), when Poland became habitable. Neolithic excavations indicated broad-ranging development in that era;

15625-511: Was under the protection of the Apostolic See . The country's early origins were described by Gallus Anonymus in Gesta principum Polonorum , the oldest Polish chronicle. An important national event of the period was the martyrdom of Saint Adalbert , who was killed by Prussian pagans in 997 and whose remains were reputedly bought back for their weight in gold by Mieszko's successor, Bolesław I
