The prevailing wind is from the southwest and bears frequent spells of mild and wet weather from the Atlantic Ocean, although the eastern parts are mostly sheltered from this wind. Since the majority of the rain falls over the western regions,
795-587: A welfare state was established, and a comprehensive, publicly funded healthcare system, the National Health Service , was created. The rise of nationalism in the colonies coincided with Britain's much-diminished economic position, so that a policy of decolonisation was unavoidable. Independence was granted to India and Pakistan in 1947. Over the next three decades, most colonies of the British Empire gained their independence, and many became members of

Powered wing-folding
1749-403: A dedicated M2 version was developed called the ".50 Browning AN/M2" or the "12.7 mm AN/M2". The "AN" stands for "Army/Navy", since the gun was developed jointly for use by both services. The AN/M2 designation was also used for other aircraft guns and therefore it is important to write the caliber before the designation. The 12.7 mm AN/M2 had a cyclic rate of 600–800 rounds per minute, with

Current ammunition types include M33 Ball (706.7 grain) for personnel and light material targets, M17 tracer, M8 API (622.5 grain), M20 API-T (619 grain), and M962 SLAP-T. The latter ammunition along with
2226-614: A heavily sandbagged tripod, the M2HB proved very useful in either a defensive role or to interdict or block road intersections from use by German infantry and motorized forces. Hearing the sound of an M2 could often cause enemy infantry to take cover. There are numerous instances of the M2 Browning being used against enemy personnel, particularly infantry assaults or for interdiction or elimination of enemy artillery observers or snipers at distances too great for ordinary infantry weapons. The M2HB

The TT.2 was a large, but clean-looking twin-engined, mid-wing cantilever monoplane design with a distinctively elongated glazed nose in its target tug configuration. The all-metal monocoque fuselage was built in four sections ending at a cantilever tailplane with single fin and rudder. Rudder and tailplanes were fabric covered. The wing design featured a swept leading edge and taper on outboard sections, and wing folds outboard of
3657-448: A new slotted flash suppressor that reduces muzzle flash by 95 percent, fixed headspace and timing, a modified bolt, and a manual trigger block safety. When a standard M2 had a barrel change, the headspace and timing had to be manually set. Improper adjustment could damage the weapon and cause serious injury to the user. Fixed headspace and timing reduces risk, and the carrying handle allows the barrel to be switched in seconds. In June 2011,

It worked closely with
11607-472: The Name of Great Britain". The term "United Kingdom" has occasionally been used as a description for the former Kingdom of Great Britain , although its official name from 1707 to 1800 was simply "Great Britain". The Acts of Union 1800 formed the United Kingdom of Great Britain and Ireland . Following the partition of Ireland and the independence of the Irish Free State in 1922, which left Northern Ireland as
11766-670: The Niger Delta, N.E Nigeria, the Jos Plateau, and in Mali. The M2 machine gun has also been used as a long-range sniper rifle when equipped with a high-powered telescopic sight . Soldiers during the Korean War used scoped M2s in the role of a sniper rifle, but the practice was most notably used by US Marine Corps sniper Carlos Hathcock during the Vietnam War. Using an Unertl telescopic sight and
11925-605: The Normans conquered England . With the end of the Wars of the Roses the English state stabilised and began to grow in power, resulting by the 16th century in the annexation of Wales , the domination of Scotland , and the establishment of the British Empire . Over the course of the 17th century, the role of the British monarchy was reduced, particularly as a result of the English Civil War . In 1707,
12084-481: The Royal Navy no longer had the platforms from which the Sturgeon was intended to operate and the requirement for the Sturgeon S.1 was cancelled. The production order for 30 aircraft was reduced to 23 and changed to a variant reworked under Q.1/46 to accommodate a largely shore-based target tug role as the S.39 (later re-indexed as the S.A.2) Sturgeon TT.2. The third prototype, RK794 , was completed to TT.2 standard with
12243-426: The S.38 Sturgeon began with the 1943 S.6/43 requirement for a high-performance torpedo bomber with a bomb bay that could accommodate six 500-pound (230 kg) bombs or any of the current standard aerial torpedoes , operating from Audacious and Centaur -class aircraft carriers . A maximum all-up-weight of 24,000 lb (11,000 kg) was specified. Short Brothers were not invited to respond to S.6/43, but
12402-529: The SB.1 piloted by Shorts' Chief Test Pilot, Tom Brooke-Smith , took off from RAF Aldergrove on 30 July 1951. The SB.1 was towed behind to a 10,000 ft altitude with the flight completed successfully. On the second flight of the day, the tow rope was extended and Brooke-Smith experienced the problems inherent in flying a light aircraft in the turbulence caused by the towing aircraft. Brooke-Smith had to cast off at low altitude and while attempting to side-slip out of
12561-701: The Scottish electorate voting by 55.3 to 44.7% to remain part of the United Kingdom. In 2016, 51.9 per cent of voters in the United Kingdom voted to leave the European Union . The UK left the EU in 2020. On 1 May 2021, the EU–UK Trade and Cooperation Agreement came into force. The COVID-19 pandemic had a severe impact on the UK's economy , caused major disruptions to education and had far-reaching impacts on society and politics in 2020 and 2021. The United Kingdom
12720-548: The Second World War damaged Britain's economic power and a global wave of decolonisation led to the independence of most British colonies. The United Kingdom is a constitutional monarchy and parliamentary democracy . The UK has three distinct jurisdictions: England and Wales , Scotland , and Northern Ireland . Since 1999, Scotland, Wales and Northern Ireland have their own governments and parliaments which control various devolved matters. A developed country ,
12879-479: The TT.2 naval target tug spent most of its life with No. 728 Squadron at Hal Far, Malta . The type was also operated by No. 771 Squadron at RNAS Ford in 1950–1954. Their primary role as a target tug included towing targets for ground-to-air firing practice, photographic marking of ground-to-air firing, target towing for air-to-air practice by night and day, "throw-off" target practice and radar calibration. All existing Sturgeon TT.2s were planned to be modified to
13038-492: The UK has the world's sixth-largest economy by nominal gross domestic product (GDP). It is a nuclear state , and is ranked fifth globally in military expenditure . The UK has been a permanent member of the UN Security Council since its first session in 1946. It is a member of the Commonwealth of Nations , Council of Europe , G7 , OECD , NATO , Five Eyes , AUKUS and CPTPP . British influence can be observed in
13197-484: The UK in 2023 is estimated to be 3.25 million hectares, which represents 13% of the total land area in the UK. Most of the United Kingdom has a temperate climate, with generally cool temperatures and plentiful rainfall all year round. The temperature varies with the seasons seldom dropping below 0 °C (32 °F ) or rising above 30 °C (86 °F). Some parts, away from the coast, of upland England, Wales, Northern Ireland and most of Scotland, experience
13356-908: The UK into lowland and upland areas. Lowland areas include Cornwall , the New Forest , the South Downs and the Norfolk Broads . Upland areas include the Lake District , the Pennines , the Yorkshire Dales , Exmoor , and Dartmoor . The main rivers and estuaries are the Thames , Severn , and the Humber . England's highest mountain is Scafell Pike , at 978 metres (3,209 ft) in the Lake District; its largest island
13515-402: The United Kingdom and that elsewhere "British government" is used at least as frequently as "United Kingdom government". The UK Permanent Committee on Geographical Names recognises "United Kingdom", "UK" and "U.K." as shortened and abbreviated geopolitical terms for the United Kingdom of Great Britain and Northern Ireland in its toponymic guidelines; it does not list "Britain" but notes that "it
13674-411: The United Kingdom is 1339.7 hours, which is just under 30% of the maximum possible. The hours of sunshine vary from 1200 to about 1580 hours per year, and since 1996 the UK has been and still is receiving above the 1981 to 2010 average hours of sunshine. Climate change has a serious impact on the country. A third of food price rise in 2023 is attributed to climate change. As of 2022, the United Kingdom
13833-436: The United Kingdom use several different terms to describe their national identity and may identify themselves as being British , English , Scottish , Welsh , Northern Irish , or Irish ; or as having a combination of different national identities. Settlement by Cro-Magnons of what was to become the United Kingdom occurred in waves beginning by about 30,000 years ago. The island has been continuously inhabited only since
13992-663: The United Kingdom. The 1928 Equal Franchise Act gave women electoral equality with men in national elections. Strikes in the mid-1920s culminated in the General Strike of 1926 . Britain had still not recovered from the effects of the First World War when the Great Depression (1929–1932) led to considerable unemployment and hardship in the old industrial areas, as well as political and social unrest with rising membership in communist and socialist parties. A coalition government
14151-626: The United States to establish the IMF , World Bank and NATO . The war left the UK severely weakened and financially dependent on the Marshall Plan , but it was spared the total war that devastated eastern Europe. In the immediate post-war years, the Labour government under Clement Attlee initiated a radical programme of reforms, which significantly impacted British society in the following decades . Major industries and public utilities were nationalised ,
14310-437: The ability to be fired from an electrically operated remote-mount solenoid trigger when installed as a fixed gun. Cooled by the aircraft's slip-stream, the air-cooled 12.7 mm AN/M2 was fitted with a substantially lighter 36-inch (91 cm) length barrel, reducing the weight of the complete unit to 61 pounds (28 kg), which also had the effect of increasing the rate of fire. The full official designation for this weapon
14469-559: The acquisition and settlement of overseas colonies , particularly in North America and the Caribbean. Though previous attempts at uniting the two kingdoms within Great Britain in 1606, 1667, and 1689 had proved unsuccessful, the attempt initiated in 1705 led to the Treaty of Union of 1706 being agreed and ratified by both parliaments. On 1 May 1707, the Kingdom of Great Britain was formed,
14628-601: The action fully. The adapter is very distinctive, attaching to the muzzle with three rods extending back to the base. The BFA can often be seen on M2s during peacetime operations. The M2 .50 Browning machine gun has been used for various roles: At the outbreak of the Second World War, the United States had versions of the M2 in service as fixed aircraft guns, anti-aircraft defensive guns (on aircraft, ships, or boats), infantry (tripod-mounted) guns, and as dual purpose anti-aircraft and anti-vehicular weapons on vehicles. The .50 AN/M2 light-barrel aircraft Browning used in planes had
14787-507: The aircraft (AN/M2) version of the gun, while beam/waist-mounted and turret-mounted Brownings were used later in the war in such aircraft as the Short Sunderland and Lancaster bomber . After World War II, the .50 Browning continued to see action in Korea and other theaters, in aircraft, tripod (ground), ground AA (hip-ring), and vehicle mounts. One of its most notable actions in a ground role
14946-719: The ammunition fed only from the left side. Service trials raised doubts about whether the guns would be suitable for aircraft or for anti-aircraft use. A heavy barrel M1921 was considered for ground vehicles. John M. Browning died in 1926. Between 1927 and 1932, S.H. Green studied the design problems of the M1921 and the needs of the armed services. The result was a single receiver design that could be turned into seven types of .50 caliber machine guns by using different jackets, barrels, and other components. The new receiver allowed right or left side feed. In 1933, Colt manufactured several prototype Browning machine guns (including what would be known as
15105-464: The ammunition. This ammunition was type classified in 1993. When firing blanks, a large blank-firing adapter (BFA) of a special type must be used to allow the recoil-operated action to cycle. This functions on the principle of a recoil booster , to increase the recoil force acting on the short recoil action. This is the exact antithesis of a muzzle brake . Without this adaptor, the reduced-charge blank cartridge would develop too little recoil to cycle
15264-529: The bolt release can be unlocked into the up position resulting in single-shot firing (the gunner must press the bolt latch release to send the bolt forward). Unlike virtually all other modern machine guns, it has no safety (although a sliding safety switch has recently been fielded to USMC armorers for installation on their weapons and is standard-issue for the U.S. Army for all M2s). Troops in the field have been known to add an improvised safety measure against accidental firing by slipping an expended shell casing under
15423-407: The bolt release in the center. The spade handles are gripped and the butterfly trigger is depressed with one or both thumbs. Recently, new rear buffer assemblies have used squeeze triggers mounted to the handgrips, doing away with the butterfly triggers. When the bolt release is locked down by the bolt latch release lock on the buffer tube sleeve, the gun functions in fully automatic mode. Conversely,
15582-408: The bore within a few thousand rounds, necessitating replacement. In addition to full automatic, the M2HB can be selected to fire single shots, fire slowly at less than 40 rounds per minute, or fire rapidly for more than 40 rounds per minute. Slow and rapid firing modes use 5–7 round bursts with different lengths of pause between bursts. The M2 has an effective range of 1,830 metres (2,000 yd) and
15741-472: The butterfly trigger. The upgraded M2A1 has a manual trigger block safety. Because the M2 was designed to operate in many configurations, it can be adapted to feed from the left or right side of the weapon by exchanging the belt-holding pawls, and the front and rear cartridge stops (three-piece set to include link stripper), then reversing the bolt switch. The operator must also convert the top-cover belt feed slide assembly from left to right-hand feed as well as
15900-410: The cartridge in the chamber. The round can be too tight in the chamber and the gun would not fire, or be too loose in the chamber, resulting in a stoppage or ruptured cartridge. The other dimension that could not be held closely enough was when the firing pin would fall. The solution to these problems was adjustable timing and headspace ("Timing" is the adjustment of the gun so that firing takes place when
16059-528: The conflict. The larger rounds were needed to pierce the armor that was being introduced to the battlefield, both on the ground and in the air. Germany introduced the Junkers J.I aircraft, whose armor could render ineffective aircraft machine guns that used conventional rifle ammunition such as the .30-06. Consequently, the American Expeditionary Force 's commander General John J. Pershing asked for
16218-697: The decades-long process of European integration , the UK was a founding member of the Western European Union , established with the London and Paris Conferences in 1954. In 1960 the UK was one of the seven founding members of the European Free Trade Association (EFTA), but in 1973 it left to join the European Communities (EC). In a 1975 referendum 67% voted to stay in it. When the EC became
16377-477: The eastern parts are the driest. Atlantic currents, warmed by the Gulf Stream , bring mild winters, especially in the west where winters are wet and even more so over high ground. Summers are warmest in the southeast of England and coolest in the north. Heavy snowfall can occur in winter and early spring on high ground, and occasionally settles to great depth away from the hills. The average total annual sunshine in
16536-564: The end of World War II. The M2 Heavy Barrel, M48 Turret Type was developed for the commander's cupola on the M48 Patton tank. The cupola mount on the M48A2 and M48A3 was thoroughly disliked by most tankers, as it proved unreliable in service. An externally mounted M2 was later adopted for the commander's position on the M1 Abrams tanks. Three subvariants were also developed for use by the U.S. Navy on
16695-455: The engine block or fuel tanks of a German Bf 109 fighter attacking at low altitude, or perforate the hull plates and fuel tanks of a German half-track or light armored car . It could even penetrate the sides and rear of the Panzer I , Panzer II , Panzer III , and Panzer IV tanks. While the dual-purpose mounting was undeniably useful, it did normally require the operator to stand when using
16854-572: The fact that the individual M2HB's rate of fire (450–550 rounds per minute) was low for an effective anti-aircraft weapon. Towards the end of the war, as Luftwaffe attacks became less frequent, the quad .50 (nicknamed the Meat Chopper or Krautmower ) was increasingly used in an anti-personnel role, similarly to the earlier-introduced (1940) and more powerful—but much more difficult to keep well-fed with ammunition when in action—German 20 mm Flakvierling . Snipers firing from trees were engaged by
17013-404: The first industrialised country and was the world's foremost power for the majority of the 19th and early 20th centuries, particularly during the " Pax Britannica " between 1815 and 1914. At its height in the 1920s, the British Empire encompassed almost a quarter of the world's landmass and population, and was the largest empire in history . However, its involvement in the First World War and
17172-575: The first year, Britain and its Empire continued the war against Germany. Churchill engaged industry, scientists and engineers to support the government and the military in the prosecution of the war effort. In 1940, the Royal Air Force defeated the German Luftwaffe in the Battle of Britain . Urban areas suffered heavy bombing during the Blitz . The Grand Alliance of Britain, the United States and
17331-569: The formal control it exerted over its own colonies, British dominance of much of world trade meant that it effectively controlled the economies of regions such as East Asia and Latin America . Throughout the Victorian era , political attitudes favoured free trade and laissez-faire policies. Beginning with the Great Reform Act in 1832, Parliament gradually widened the voting franchise , with
17490-403: The front of the spar , placing him level with the leading edge of the wing, the navigator was behind the centre section of the wing and the radio operator — separated from the navigator by his equipment — behind him. The navigator and radio operator entered through a door, which acted as a ladder when opened, in the starboard side with their seats being offset to port. The cameras were installed in
17649-412: The fuselage behind the radio operator. One of the Sturgeon's unfortunate failings was in placement of controls. The fire extinguisher switch was located next to the cockpit switches required for firing the engine starter cartridges, resulting in some inadvertent mishaps and some unintended hilarity for ground crews. Armament would be two 0.5 in (12.7 mm) Browning machine guns in the nose with
17808-731: The global hegemon and adopted the role of global policeman. From 1853 to 1856, Britain took part in the Crimean War , allied with the Ottoman Empire against Tsarist Russia , participating in the naval battles of the Baltic Sea known as the Åland War in the Gulf of Bothnia and the Gulf of Finland , among others. Following the Indian Rebellion in 1857 , the British government led by Lord Palmerston assumed direct rule over India . Alongside
17967-547: The heavy barrel compensated somewhat for the loss of water-cooling, while reducing bulk and weight: the M2 weighs 121 lb (55 kg) with a water jacket, but the M2 HB weighs 84 lb (38 kg). Due to the long procedure for changing the barrel, an improved system was developed called QCB (quick change barrel). The lightweight "Army/Navy" prefixed AN/M2 "light-barrel" version of the Browning M2 weighing 60 pounds (27 kg)
18126-544: The introduction is Browning Machine Gun, Cal. .50, M2, with others as described below. The development of the M1921 water-cooled machine gun which led to the M2, meant that the initial M2s were, in fact, water-cooled. These weapons were designated Browning Machine Gun, Cal. .50, M2, Water-Cooled, Flexible. There was no fixed water-cooled version. Improved air-cooled heavy barrel versions came in three subtypes. The basic infantry model, Browning Machine Gun, Cal. .50, M2, HB, Flexible,
18285-403: The kingdoms of England, Scotland and Ireland were united in a personal union when James VI, King of Scots , inherited the crowns of England and Ireland and moved his court from Edinburgh to London; each country nevertheless remained a separate political entity and retained its separate political, legal, and religious institutions. In the mid-17th century, all three kingdoms were involved in
18444-565: The largest in Western Europe , with a population of 14.9 million. The cities of Edinburgh , Cardiff , and Belfast are the national capitals of Scotland, Wales, and Northern Ireland, respectively. The lands of the UK have been inhabited continuously since the Neolithic . In AD 43 the Roman conquest of Britain began; the Roman departure was followed by Anglo-Saxon settlement . In 1066,
18603-408: The last retreat of the ice around 11,500 years ago. By the end of the region's prehistoric period , the population is thought to have belonged largely to a culture termed Insular Celtic , comprising Brittonic Britain and Gaelic Ireland . The Roman conquest , beginning in 43 AD, and the 400-year rule of southern Britain , was followed by an invasion by Germanic Anglo-Saxon settlers, reducing
18762-409: The legal and political systems of many of its former colonies , and British culture remains globally influential, particularly in language , literature , music and sport . English is the world's most widely spoken language and the third-most spoken native language . The Acts of Union 1707 declared that the Kingdom of England and Kingdom of Scotland were "United into One Kingdom by
18921-524: The local cultures. Subsequent medieval English kings completed the conquest of Wales and tried unsuccessfully to annex Scotland . Asserting its independence in the 1320 Declaration of Arbroath , Scotland maintained its independence thereafter, albeit in near-constant conflict with England . In 1215 the Magna Carta was the first document to state that no government was above the law, that citizens have rights protecting them and that they were entitled to
19080-459: The longest confirmed kill at 2,250 metres (2,460 yd), a record which stood until 2002, when it was broken in Afghanistan by Canadian Army sniper Arron Perry . Licensed historic production: Current production (2023): The basic M2 was deployed in U.S. service in a number of subvariants, all with separate complete designations as per the US Army system. The basic designation as mentioned in
19239-487: The lower cockpit sides, and two more if the forward dorsal turret's pair of M2 guns were also aimed straight forward. The later A-26 bested this with up to a maximum of 16/18 machine guns, 8 in the nose, four more per wing in flush-mount pods, plus 2 guns in the dorsal turret. In the dual-purpose vehicle mount, the M2HB proved extremely effective in U.S. service: the Browning's .50 caliber AP and API rounds could easily penetrate
19398-655: The major part of the British Isles archipelago and includes the island of Great Britain, the north-eastern one-sixth of the island of Ireland and some smaller surrounding islands. It lies between the North Atlantic Ocean and the North Sea with the southeast coast coming within 22 miles (35 km) of the coast of northern France, from which it is separated by the English Channel . The Royal Greenwich Observatory in London
19557-669: The mid-1920s, most of the British population could listen to BBC radio programmes. Experimental television broadcasts began in 1929 and the first scheduled BBC Television Service commenced in 1936. The rise of Irish nationalism , and disputes within Ireland over the terms of Irish Home Rule , led eventually to the partition of the island in 1921. A period of conflict in what is now Northern Ireland occurred from June 1920 until June 1922. The Irish Free State became independent, initially with Dominion status in 1922, and unambiguously independent in 1931 . Northern Ireland remained part of
19716-403: The model. The M2HB air-cooled ground gun has a cyclical rate of 450–575 rounds per minute. The early M2 water-cooled AA guns had a cyclical rate of around 450–600 rpm. The AN/M2 aircraft gun has a cyclic rate of 750–850 rpm; this increases to 1,200 rpm for AN/M3 aircraft guns. These maximum rates of fire are generally not achieved in use, as sustained fire at that rate will wear out
19875-463: The only part of the island of Ireland within the United Kingdom, the name was changed in 1927 to the "United Kingdom of Great Britain and Northern Ireland". Although the United Kingdom is a sovereign country, England, Scotland, Wales and Northern Ireland are also widely referred to as countries . The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom. Some statistical summaries, such as those for
20034-634: The pilot's position, moving between stations in the nose and rear fuselage. In 1953, with the abandonment of throw-off target practice, the requirement for the camera nose disappeared and five TT.2s were converted into the S.B.9 Sturgeon TT.3 variant with a nose profile similar to that of the S.1. The penultimate and last Sturgeons were rebuilt in 1949 as prototypes for the S.B.3, a proposed anti-submarine aircraft to M.6/49, powered by two Armstrong Siddeley Mamba AS Ma3 turboprops of 1,147 shaft horsepower (855 kW ) driving two four-bladed propellers. The engine exhausts were directed downwards instead of to
20193-425: The preliminary responses from the other participating manufacturers indicated that a twin-engined design meeting all requirements was likely to weigh in excess of 24,000 lbs, while a single-engined design was unlikely to exceed the performance of in-service aircraft. S.6/43 was allowed to proceed, and there are indications that Shorts submitted two uninvited tenders, a single-engined Bristol Centaurus design and
20352-546: The program ended. In 2007, the military found money to start a new competition. Saco Defense had since been acquired by General Dynamics , which won the competition. On 15 October 2010, the M2A1 heavy machine gun was type classified by the U.S. Army. Formerly known as the M2E2, the M2A1 incorporates improvements to the design including a quick change barrel (QCB) with a removable carrying handle,
20511-475: The quad gunner at trunk level; the weapon would cut down and destroy the entire tree, and the sniper with it. The M45 Quadmount was still in use during the Vietnam War. The Commonwealth use of the M2 Browning .50 caliber machine gun (known as the .5 Browning in British and Commonwealth service) began in World War II, though from 1942 it was standard armament on US-built AFVs provided under lend-lease such as
20670-528: The rear. Another major modification was the grafting on of a gigantic bulbous nose that housed two radar operators in stations forward of the engines and the radar itself, below. Acute problems arising from the modifications led to the demise of the project, namely, "the efflux from the Mamba turboprops seriously destabilized the aircraft at some power settings and destroyed the good handling characteristics. It proved impossible to trim for safe flight on one engine which
20829-407: The receiver in order to have quick installation of various optics. The original M2HB tripod and parts can be used on the CS/LM6. When the M2 was first being designed, John Browning faced two design challenges. With the machine tools available at that time, the dimensions that established the location of the bolt face and the depth of the chamber could not be held tightly enough to control the fit of
20988-418: The recoiling parts are in the correct position for firing; "headspace" is the distance between the face of the bolt and the base of the cartridge case, fully seated in the chamber); the operator had to screw the barrel into the barrel extension, moving the barrel toward the bolt face to reach the proper headspace with simple gauges to allow the operator to adjust to the proper dimensions. By the late 20th century,
21147-497: The rest of Europe, royal absolutism would not prevail, and a professed Catholic could never accede to the throne. The British constitution would develop on the basis of constitutional monarchy and the parliamentary system . With the founding of the Royal Society in 1660, science was greatly encouraged. During this period, particularly in England, the development of naval power and the interest in voyages of discovery led to
21306-568: The result of the Acts of Union 1707 between the Kingdom of England and Kingdom of Scotland . In the 18th century, cabinet government developed under Robert Walpole , in practice the first prime minister (1721–1742). A series of Jacobite uprisings sought to remove the Protestant House of Hanover from the throne and restore the Catholic House of Stuart . The Jacobites were finally defeated at
21465-432: The spring and plunger in the feed arm. This will take a well-trained individual less than two minutes to perform. The charging assembly may be changed from left to right-hand charge. A right-hand charging handle spring, lock wire, and a little "know-how" are all that is required to accomplish this. The M2 can be battle-ready and easily interchanged if it is preemptively fitted with a retracting slide assembly on both sides of
21624-436: The twelve NUTS 1 regions , refer to Scotland, Wales and Northern Ireland as "regions". Northern Ireland is also referred to as a "province". With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice often revealing one's political preferences". The term "Great Britain" conventionally refers to the island of Great Britain, or politically to England, Scotland and Wales in combination. It
21783-504: The twin Merlin 140 engines driving contra-rotating propellers (which allowed shorter blades and the Merlins to be mounted closer to the centreline). The main wheels retracted rearwards into the engine nacelles while the tail wheel retracted forwards into the fuselage. Radiators were mounted in the leading edge between the nacelles and the fuselage . The Sturgeon's post-war role began as
21942-730: The wake, struck the ground "nose-down" at 90 mph, injuring himself seriously and damaging the aircraft. With the extensive damage to the Short SB.1 necessitating a rebuild, the decision to power the modified glider (redesignated the Short SB.4 Sherpa ) meant the end of the use of the Sturgeon tow aircraft in the programme. Data from The World's Worst Aircraft., The Aircraft of the World, General characteristics Performance Aircraft of comparable role, configuration, and era Related lists United Kingdom The United Kingdom of Great Britain and Northern Ireland , commonly known as
22101-466: The weapon system. This eliminates the need to have the weapon removed from service to accomplish this task. At some point during World War II, the Frankford Arsenal developed a squeeze bore version of the M2HB which reduced the bullet size from .50 to .30 caliber. There are several different types of ammunition used in the M2HB and AN aircraft guns. From World War II through the Vietnam War ,
22260-463: The weapon. Since Finland was already producing 12.7 mm ammunition, the Finnish variant was rechambered to 12.7 mm (.50 BMG). The Finnish variant was designated VKT 12,70 LKk/42 and was produced by Finland. The M2 machine gun was widely used during World War II, and in later postwar conflicts, as a remote or flexible aircraft gun. For fixed (offensive) or flexible (defensive) guns used in aircraft,
22419-458: Was "Browning Machine Gun, Aircraft, Cal. .50, AN/M2" (Fixed) or (Flexible). The 12.7 mm AN/M2 was used on many aircraft during WWII , as it served as the main aircraft armament in the US military. Most US fighter aircraft were armed with four, six or eight AN/M2 MGs mounted in the wings. Some examples being the Curtiss P-40 , Republic P-47 Thunderbolt , and North American P-51 Mustang for
22578-477: Was a necessity for long endurance on anti-submarine patrols." Two S.B.3 prototypes were ordered with the first, WF632 flying on 8 December 1950 at Belfast. The design proved extremely difficult to trim when flying on one engine and so unstable that no effort was made to resolve these problems; consequently, the project was cancelled before the second prototype, WF636 flew. Both aircraft had very short lives, being scrapped in 1951. The main production variant,
22737-491: Was also developed, and became the standard .50-caliber aviation machine gun of the World War II–era for American military aircraft of nearly every type, readily replacing Browning's own air-cooled .30 caliber machine gun design in nearly all American aircraft installations. The Browning M2 is an air-cooled , belt-fed machine gun. The M2 fires from a closed bolt , operated on the short recoil principle. The M2 fires
22896-418: Was also required. Shorts submitted the twin-Merlin S.38 Sturgeon as their tender to S.11/43, while Armstrong Whitworth proposed the twin-Merlin powered AW.54. After the AW.54 was criticized for lack of power, the AW.54A with two MetroVick F.3 turbojets was submitted. Submissions were also made by Blackburn and Fairey (also with twin-Merlin designs) and by Westland with a mixed-power design comprising
23055-431: Was chambered for the .30-06 cartridge, the M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible . It has been used against infantry, light armored vehicles, watercraft, light fortifications, and low-flying aircraft. The gun has been used extensively as
23214-416: Was chosen as the defining point of the Prime Meridian at the International Meridian Conference in 1884. The United Kingdom lies between latitudes 49° and 61° N , and longitudes 9° W and 2° E . Northern Ireland shares a 224-mile (360 km) land boundary with the Republic of Ireland. The coastline of Great Britain is 11,073 miles (17,820 km) long, though measurements can vary greatly due to
23373-485: Was completed in March 2017, with 3,600 M2A1s planned to be fielded by the Marines in total. The Israel Defense Forces adopted the M2-HQCB (the commercial version of the M2A1) in 2012 as a replacement to the M2HB. One derivative of the M2 Browning is the Mitrailleuse d´Avion Browning - F.N. Calibre 13,2 mm , more commonly known as the FN Browning M.1939. The FN Browning M.1939 was a heavily modified M2 Browning for aircraft use designed by FN Herstal for export. Their aim
23532-413: Was designed for this gun. It was of a high explosive type and was designed to take down a small aircraft with a single hit. Tests showed that it was very effective against both cloth and aluminum skinned aircraft. Due to the aforementioned improvements, the gun received interest from numerous nations when it entered the export market in 1939. Due to the start of World War 2 and the invasion of Belgium it
23691-417: Was exported to only Romania and Sweden . Sweden was able to buy the majority of the weapons along with the blueprints to produce the weapon on their own without paying for a license. In Sweden, the weapon received the designation Automatkanon m/39, short Akan m/39, meaning Autocannon m/39 and was later produced by Ericsson as the Akan m/39A. Sweden also gave the blueprints to Finland so they could produce
23850-404: Was formed in 1931. Nonetheless, "Britain was a very wealthy country, formidable in arms, ruthless in pursuit of its interests and sitting at the heart of a global production system." After Nazi Germany invaded Poland in 1939, Britain entered the Second World War . Winston Churchill became prime minister and head of a coalition government in 1940. Despite the defeat of its European allies in
24009-436: Was heavy, difficult to control, fired too slowly for the anti-personnel role, and was not powerful enough against armor. While the .50-caliber was being developed, some 13.2×92mmSR Mauser 1918 T-Gewehr anti-tank rifles and its ammunition were captured. The 13.2 mm German rounds had a muzzle velocity of 2,700 ft/s (820 m/s), an 800 gr (52 g) bullet, and could penetrate armor 1 in (25 mm) thick at
24168-415: Was in a fierce battle with a nine-man Special Air Service team at the Battle of Mirbat in Oman in July 1972, where the heavy Browning and its API ammunition was used to help repulse an assault by 250 Yemeni Adoo guerrillas, though the more famous weapon from the battle is a 25 pounder gun . The Scots Guards used the weapon in the 1982 Falklands War . A .50 caliber Browning was installed along with
24327-469: Was killed during the firefight and was posthumously awarded the Medal of Honor . The M45 Quadmount was a mounting of four .50 M2HB guns with a single gunner situated behind an armored housing. This was used by U.S. anti-air battalions, fitted either on a towed trailer or mounted on a half-track carrier. With 200 rounds per gun in a powered tracking mount, the guns proved very effective against low-flying aircraft. The use of four guns adequately compensated for
24486-415: Was not widely used in the Pacific campaign for several reasons, including the weight of the gun, the nature of infantry jungle combat, and because road intersections were usually easily outflanked. However, it was used by fast-moving motorized forces in the Philippines to destroy Japanese blocking units on the advance to Manila. The quad mount .50 was also used to destroy Japanese emplacements. The M2HB
24645-413: Was reassigned from Short Brothers to Short Brothers & Harland and the incomplete aircraft were moved to Belfast where the second prototype, RK791 , flew from Sydenham , Belfast on 18 May 1948. RK791 competed in the Air League Challenge Cup Race of 1949 with an average speed of 295 mph. With the end of the Second World War and the suspension of the Audacious and Centaur -class carriers
24804-425: Was suspended and the original reconnaissance bomber specification was cancelled. The Sturgeon was then redesigned as a target tug which saw service with the fleet for a number of years. Later, the basic Sturgeon design was reworked as a prototype anti-submarine aircraft. The many modifications that resulted turned the promising design into a "hapless and grotesque-looking hybrid." The development process leading to
24963-432: Was the first country in the world to use an approved COVID-19 vaccine , developing its own vaccine through a collaboration between Oxford University and AstraZeneca , which allowed the UK's vaccine rollout to be among the fastest in the world. The total area of the United Kingdom is approximately 94,354 square miles (244,376 km ), with a land area of 93,723 square miles (242,741 km ). The country occupies
25122-406: Was to make a light, reliable heavy machine gun with the same damage output as a 20 mm autocannon. To achieve this, they raised the firing rate to 1080 rpm and gave it a more powerful cartridge in the form of the 13.2×99mm Hotchkiss . This cartridge was a popular Eurasian analog of .50 BMG developed independently in 1920s with a 13.2 mm bullet (.52 in) and more propellant. A new projectile
25281-404: Was used in Korea and Vietnam, and later in both Operation Desert Storm , the Afghan theater of Operation Enduring Freedom and in Iraq . In 2003, U.S. Army SFC Paul Ray Smith used his M2HB mounted on an M113 armored personnel carrier to kill 20 to 50 enemies who were attacking a U.S. outpost, preventing an aid station from being overrun and allowing wounded soldiers to be evacuated, SFC Smith
