North American P-51 Mustang
–
The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II, the Korean War and other conflicts. The Mustang was designed in 1940 by North American Aviation in response to a requirement of the British Purchasing Commission, the Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force. Rather than build an old design from another company, North American Aviation proposed the design, the prototype NA-73X airframe was rolled out on 9 September 1940,102 days after the contract was signed, and first flew on 26 October. The Mustang was originally designed to use the Allison V-1710 engine and it was first flown operationally by the RAF as a tactical-reconnaissance aircraft and fighter-bomber. The addition of the Rolls-Royce Merlin to the P-51B/C model transformed the Mustangs performance at altitudes above 15,000 ft, the P-51 was also used by Allied air forces in the North African, Mediterranean, Italian and Pacific theaters. During World War II, Mustang pilots claimed to have destroyed 4,950 enemy aircraft, despite the advent of jet fighters, the Mustang remained in service with some air forces until the early 1980s. After the Korean War, Mustangs became popular civilian warbird and air racing aircraft, in April 1940 the British government established a purchasing commission in the United States, headed by Sir Henry Self. Self was given responsibility for Royal Air Force production and research and development, and also served with Sir Wilfrid Freeman. Self also sat on the British Air Council Sub-committee on Supply and one of his tasks was to organize the manufacturing and supply of American fighter aircraft for the RAF. At the time, the choice was limited, as no U. S. aircraft then in production or flying met European standards. The Curtiss-Wright plant was running at capacity, so P-40s were in short supply, North American Aviation was already supplying its Harvard trainer to the RAF, but was otherwise underutilized. NAA President Dutch Kindelberger approached Self to sell a new medium bomber, instead, Self asked if NAA could manufacture the Tomahawk under license from Curtiss. Kindelberger said NAA could have an aircraft with the same engine in the air sooner than establishing a production line for the P-40. In March 1940,320 aircraft were ordered by Sir Wilfred Freeman who had become the head of the Ministry of Aircraft Production. The NA-73X, which was designed by a led by lead engineer Edgar Schmued, followed the best conventional practice of the era. One was a wing designed using laminar flow airfoils which were developed co-operatively by North American Aviation and these airfoils generated very low drag at high speeds. The results of this test showed the superiority of the wing designed with the NAA/NACA 45–100 airfoils, the other feature was a new cooling arrangement that reduced the cooling drag. It was later discovered that, after lot of development, the assembly could take advantage of the Meredith Effect

South Africa
–
South Africa, officially the Republic of South Africa, is the southernmost country in Africa. South Africa is the 25th-largest country in the world by land area and it is the southernmost country on the mainland of the Old World or the Eastern Hemisphere. About 80 percent of South Africans are of Sub-Saharan African ancestry, divided among a variety of ethnic groups speaking different Bantu languages, the remaining population consists of Africas largest communities of European, Asian, and multiracial ancestry. South Africa is a multiethnic society encompassing a variety of cultures, languages. Its pluralistic makeup is reflected in the recognition of 11 official languages. The country is one of the few in Africa never to have had a coup détat, however, the vast majority of black South Africans were not enfranchised until 1994. During the 20th century, the black majority sought to recover its rights from the dominant white minority, with this struggle playing a role in the countrys recent history. The National Party imposed apartheid in 1948, institutionalising previous racial segregation, since 1994, all ethnic and linguistic groups have held political representation in the countrys democracy, which comprises a parliamentary republic and nine provinces. South Africa is often referred to as the Rainbow Nation to describe the multicultural diversity. The World Bank classifies South Africa as an economy. Its economy is the second-largest in Africa, and the 34th-largest in the world, in terms of purchasing power parity, South Africa has the seventh-highest per capita income in Africa. However, poverty and inequality remain widespread, with about a quarter of the population unemployed, nevertheless, South Africa has been identified as a middle power in international affairs, and maintains significant regional influence. The name South Africa is derived from the geographic location at the southern tip of Africa. Upon formation the country was named the Union of South Africa in English, since 1961 the long form name in English has been the Republic of South Africa. In Dutch the country was named Republiek van Zuid-Afrika, replaced in 1983 by the Afrikaans Republiek van Suid-Afrika, since 1994 the Republic has had an official name in each of its 11 official languages. Mzansi, derived from the Xhosa noun umzantsi meaning south, is a name for South Africa. South Africa contains some of the oldest archaeological and human fossil sites in the world, extensive fossil remains have been recovered from a series of caves in Gauteng Province. The area is a UNESCO World Heritage site and has termed the Cradle of Humankind

South African Air Force
–
The South African Air Force is the air force of South Africa, with headquarters in Pretoria. The South African Air Force was established on 1 February 1920, the Air Force has seen service in World War II and the Korean War. From 1966 the SAAF was involved in providing support in a low intensity war in Angola, South-West Africa. On conclusion of the Border War in 1990, aircraft numbers were reduced due to economic pressures as well as the cessation of hostilities with neighboring states. Today the SAAF has an air combat capability and has been structured towards regional peace-keeping, disaster relief. After a visit to observe the 1912 military manoeuvres in Europe, beyers gave an extremely positive report on the future use of aircraft for military purposes to General Smuts. Flying training commenced in 1913 with students who excelled on the course being sent to the Central Flying School at Upavon in Great Britain for further training, the first South African military pilot qualified on 2 June 1914. At the outbreak of World War I, the Union Defence Force had realised the urgent need for air support which brought about the establishment of the South African Aviation Corps on 29 January 1915. Aircraft were purchased from France while the building of an airfield at Walvis Bay commenced in earnest in order to support operations against German forces in German South West Africa. By June 1915 the SAAC was deployed to its first operational airfield at Karibib in German South West Africa in support of Gen. Bothas South African ground forces. On 9 July 1915, the German forces capitulated and most of the pilots,26 Squadron RFC and later becoming an independent squadron on 8 October 1915. No.26 Squadron was equipped with Henri Farman F-27s and B. E. 2cs and was shipped to Kenya in support of the war effort in German East Africa, landing in Mombasa on 31 January 1916. While the SAAC were engaged in German South West Africa and 26 Sqdn RFC in East Africa, the number of South Africans in the RFC eventually reached approximately 3,000 men and suffered 260 active-duty fatalities over the Somme during the war. Forty six pilots became fighter aces, on conclusion of the First World War, the British Government donated surplus aircraft plus spares and sufficient equipment to provide the nucleus of a fledgling air force to each of its Dominions. In December 1920 the South African National insignia was added to aircraft for the first time and these colours remained until 1927 when they were replaced with the Orange, White and Blue roundels. 1 Squadron was called to fly reconnaissance missions and to bombard the strikers’ positions, the SAAF was again deployed to suppress the Bondelzwart Rebellion at Kalkfontein between 29 May and 3 July 1922. For maritime patrol operations, the SAAF took over all 29 passenger aircraft of South African Airways,18 Junkers Ju 86Z-ls for maritime patrols, SAAF maritime patrols commenced on 21 September 1939 with 16 Squadron flying three JU-86Zs from Walvis Bay. By 1940, the Ju 86s were replaced by Ansons and Coastal Command SAAF had been established, in December 1939 the Duke of Aosta had sent a report to Mussolini recording the state of chronic unpreparedness of the Allied Forces in East Africa

Cheetah
–
The cheetah /ˈtʃiːtə/ is a large felid of the subfamily Felinae that occurs mainly in eastern and southern Africa and a few parts of Iran. The only extant member of the genus Acinonyx, the cheetah was first described by Johann Christian Daniel von Schreber in 1775. The cheetah is characterised by a body, deep chest, spotted coat, a small rounded head, black tear-like streaks on the face, long thin legs. Its lightly built, slender form is in sharp contrast with the robust build of the big cats, the cheetah reaches nearly 70 to 90 cm at the shoulder, and weighs 21–72 kg. Though taller than the leopard, it is smaller than the lion. Basically yellowish tan or rufous to white, the coat is uniformly covered with nearly 2,000 solid black spots. Cheetahs are active mainly during the day, with hunting their major activity, adult males are sociable despite their territoriality, forming groups called coalitions. Females are not territorial, they may be solitary or live with their offspring in home ranges, carnivores, cheetah mainly prey upon antelopes and gazelles. They will stalk their prey to within 100–300 metres, charge towards it and kill it by tripping it during the chase, the cheetahs body is specialised for speed, it is the fastest land animal. Cheetahs are induced ovulators, breeding throughout the year, gestation is nearly three months long, resulting in a litter of typically three to five cubs. Weaning occurs at six months, siblings tend to stay together for some time, Cheetah cubs face higher mortality than most other mammals, especially in the Serengeti region. Cheetahs inhabit a variety of habitats – dry forests, scrub forests, thanks to its prowess at hunting, the cheetah was tamed and used to kill game at hunts in the past. The animal has been depicted in art, literature, advertising. Classified as vulnerable by the International Union for Conservation of Nature, several African countries have taken steps to improve the standards of cheetah conservation. The vernacular name cheetah is derived from the Hindi word चीता, the first recorded use of this word has been dated back to 1610. An alternative name for the cheetah is hunting leopard, the scientific name of the cheetah is Acinonyx jubatus. The generic name Acinonyx could have originated from the combination of two Greek words, akinetos means motionless, and onyx means claw, a rough translation of the word would be non-moving claws, a reference to the limited retractability of the claws of the cheetah relative to other cats. The specific name jubatus means maned in Latin, referring to the dorsal crest of this animal, the cheetah is the only extant species of the genus Acinonyx

Saab JAS 39 Gripen
–
The Saab JAS39 Gripen is a light single-engine multirole fighter aircraft manufactured by the Swedish aerospace company Saab. It was designed to replace the Saab 35 Draken and 37 Viggen in the Swedish Air Force, the Gripen has a delta wing and canard configuration with relaxed stability design and fly-by-wire flight controls. It is powered by the Volvo RM12, and has a top speed of Mach 2, later aircraft are modified for NATO interoperability standards and to undertake in-flight refuelling. In 1979, the Swedish government began development studies for a capable of fighter, attack. A new design from Saab was selected and developed as the JAS39, following two crashes during flight development and subsequent alterations to the aircrafts flight control software, the Gripen entered service with the Swedish Air Force in 1997. Upgraded variants, featuring more advanced avionics and adaptations for longer mission times, in order to market the aircraft to export customers, Saab has formed several partnerships and collaborative efforts with multiple overseas aerospace companies. One example of efforts was Gripen International, a joint partnership between Saab and BAE Systems formed in 2001. A further version, designated Gripen JAS 39E/F, is under development as of 2014, the changes include the adoption of a new powerplant, the General Electric F414G, an active electronically scanned array radar, and significantly increased internal fuel capacity. Saab has proposed other derivatives, including a navalised Sea Gripen for carrier operations, Sweden and Brazil have ordered the Gripen E/F and Switzerland initially selected it for procurement. As of 2013, more than 247 Gripens have been built, in the late 1970s, Sweden sought to replace its ageing Saab 35 Draken and Saab 37 Viggen. One goal was for the aircraft to be smaller than the Viggen while equalling or improving on its payload-range characteristics, several foreign designs were also studied, including the General Dynamics F-16 Fighting Falcon, the McDonnell Douglas F/A-18 Hornet, the Northrop F-20 Tigershark and the Dassault Mirage 2000. Ultimately, the Swedish government opted for a new fighter to be developed by Saab, several Saab designs were reviewed, the most promising being Project 2105, recommended to the government by the Defence Materiel Administration. The preferred aircraft was a single-engine, lightweight single-seater, embracing fly-by-wire technology, canards, the powerplant selected was the Volvo-Flygmotor RM12, a license-built derivative of the General Electric F404−400, engine development priorities were weight reduction and lowering component count. On 30 June 1982, with approval from the Riksdag, the FMV issued contracts worth SEK 25.7 billion to Saab, covering five prototypes and an initial batch of 30 production aircraft. By January 1983, a Viggen was converted to a flying test aircraft for the JAS 39s intended avionics, the JAS39 received the name Gripen via a public competition, which is the heraldry on Saabs logo. The first Gripen was rolled out on 26 April 1987, marking Saabs 50th anniversary, originally planned to fly in 1987, the first flight was delayed by 18 months due to issues with the flight control system. On 9 December 1988, the first prototype took its 51-minute maiden flight with pilot Stig Holmström at the controls, during the test programme, concern surfaced about the aircrafts avionics, specifically the fly-by-wire flight control system, and the relaxed stability design. On 2 February 1989, this led to the crash of the prototype during an attempted landing at Linköping

East African Campaign (World War II)
–
Ethiopian irregulars, the Free French and Belgian troops of the Force Publique also participated. The East African Campaign was the first Allied strategic victory in the war but was overshadowed by the British defeats in Greece and Crete. Italian belligerence also closed the Mediterranean to Allied merchant ships and endangered British supply routes along the coast of East Africa, the Gulf of Aden, Red Sea and the Suez Canal. Egypt, the Suez Canal, French Somaliland and British Somaliland were also vulnerable to invasion, in the summer of 1940 Italy was far from ready for a long war or for the occupation large areas of Africa. Amedeo, Duke of Aosta, was appointed Viceroy and Governor-General of the AOI in November 1937, with a headquarters in Addis Ababa, the Ethiopian capital. On 1 June 1940, as the commander in chief of Comando Forze Armate dellAfrica Orientale Italiana and Generale dArmata Aerea, Aosta had about 290,476 local, by 1 August, mobilisation had increased the number to 371,053 troops. About 70 percent of Italian troops were locally recruited Askari, the regular Eritrean battalions and the Regio Corpo Truppe Coloniali were among the best Italian units in the AOI and included Eritrean cavalry Penne di Falco. Most colonial troops were recruited, trained and equipped for colonial repression, although the Somali Dubats from the borderlands were useful light infantry and skirmishers. Irregular bandes were hardy and mobile, knew the country and were effective scouts and saboteurs, although confused with Shifta. Due to the isolation of the AOI from the Mediterranean, the Italians had very little opportunity for reinforcements or supply, leading to severe shortages, especially of ammunition. On occasion, foreign merchant vessels captured by German merchant raiders in the Indian Ocean were brought to Somali ports, there were 183 first line aircraft and another 140 in reserve, of which 59 were operational and 81 were unserviceable. On the outbreak of war, the CAAOI had 10,700 t of fuel,5,300 t of bombs and 8,620,000 rounds of ammunition. The Italians had reserves for 75% of their strength, but lacked spare parts. The quality of the units varied, the SM.79 was the only modern bomber and the CR.32 fighter was obsolete, but the Regia Aeronautica in East Africa had a cadre of highly experienced Spanish Civil War veterans. The Regia Marina maintained the Red Sea Flotilla at Massawa in Eritrea on the Red Sea, the port was a link between Axis-occupied Europe and the naval facilities in the Italian concession zone in Tientsin in China. There were also limited port facilities at Assab, in Eritrea, the flotilla also had two local defence destroyers, the Orsini and Acerbi, a squadron of five Motoscafo Armato Silurante and eight submarines. When the Mediterranean route was closed to Allied merchant ships in April 1940, Allied convoys had to sail via the Cape and up the east coast of Africa, as Italian fuel supplies in Massawa dwindled, opportunities for the Red Sea Flotilla to attack Allied shipping declined. The British had based forces in Egypt since 1882 but these were reduced by the terms of the Anglo-Egyptian treaty of 1936

North African Campaign
–
The North African Campaign of the Second World War took place in North Africa from 10 June 1940 to 13 May 1943. It included campaigns fought in the Libyan and Egyptian deserts and in Morocco, the campaign was fought between the Allies and Axis powers, many of whom had colonial interests in Africa dating from the late 19th century. The Allied war effort was dominated by the British Commonwealth and exiles from German-occupied Europe, the United States entered the war in December 1941 and began direct military assistance in North Africa on 11 May 1942. Fighting in North Africa started with the Italian declaration of war on 10 June 1940, on 14 June, the British Armys 11th Hussars crossed the border from Egypt into Libya and captured the Italian Fort Capuzzo. Information gleaned via British Ultra code-breaking intelligence proved critical to Allied success in North Africa, victory for the Allies in this campaign immediately led to the Italian Campaign, which culminated in the downfall of the fascist government in Italy and the elimination of a German ally. On 10 May 1940, the Wehrmacht had started the Battle of France, one month later, it was plain to see that France would have to surrender within two weeks. On 10 June 1940, the Kingdom of Italy aligned itself with Nazi Germany and declared war upon France, British forces based in Egypt were ordered to undertake defensive measures, but to act as non-provocatively as possible. However, on 11 June they began a series of raids against Italian positions in Libya, following the defeat of France on 25 June, Italian forces in Tripolitania—facing French troops based in Tunisia—redeployed to Cyrenaica to reinforce the Italian Tenth Army. Italian dictator Benito Mussolini ordered the Tenth Army to invade Egypt by 8 August, two days later, no invasion having been launched, Mussolini ordered Marshal Graziani that, the moment German forces launched Operation Sea Lion, he was to attack. The battle plan was to advance along the road, while limited armoured forces operated on the desert flank. To counter the Italian advance, Wavell ordered his forces to harass the advancing Italians, falling back towards Mersa Matruh. Positioned on the flank was the 7th Armoured Division, which would strike the flank of the Italian force. By 16 September, the Italian force had advanced to Maktila, around 80 mi west of Mersa Matruh, in response to the dispersed Italian camps, the British planned a limited five-day attack, Operation Compass, to strike at these fortified camps one by one. The British Commonwealth force, totalling 36,000 men, attacked the forward elements of the 10-division-strong Italian army on 9 December, following their initial success, the forces of Operation Compass pursued the retreating Italian forces. In January, the port at Bardia was taken, soon followed by the seizure of the fortified port of Tobruk. Some 40,000 Italians were captured in and around the two ports, with the remainder of the Tenth Army retreating along the coast road back to El Agheila. Richard OConnor sent the 7th Armoured Division across the desert, with a reconnaissance group reaching Beda Fomm some ninety minutes before the Italians. Although desperate attempts were made to overcome the British force at the Battle of Beda Fomm, the Italians were unable to break through, and the remnants of the retreating army surrendered

Sicily
–
Sicily is the largest island in the Mediterranean Sea. It is an autonomous Region of Italy, along with surrounding minor islands, Sicily is located in the central Mediterranean Sea, south of the Italian Peninsula, from which it is separated by the narrow Strait of Messina. Its most prominent landmark is Mount Etna, the tallest active volcano in Europe, the island has a typical Mediterranean climate. The earliest archaeological evidence of activity on the island dates from as early as 12,000 BC. It became part of Italy in 1860 following the Expedition of the Thousand, a revolt led by Giuseppe Garibaldi during the Italian unification, Sicily was given special status as an autonomous region after the Italian constitutional referendum of 1946. Sicily has a rich and unique culture, especially regard to the arts, music, literature, cuisine. It is also home to important archaeological and ancient sites, such as the Necropolis of Pantalica, the Valley of the Temples, Sicily has a roughly triangular shape, earning it the name Trinacria. To the east, it is separated from the Italian mainland by the Strait of Messina, about 3 km wide in the north, and about 16 km wide in the southern part. The northern and southern coasts are each about 280 km long measured as a line, while the eastern coast measures around 180 km. The total area of the island is 25,711 km2, the terrain of inland Sicily is mostly hilly and is intensively cultivated wherever possible. Along the northern coast, the ranges of Madonie,2,000 m, Nebrodi,1,800 m. The cone of Mount Etna dominates the eastern coast, in the southeast lie the lower Hyblaean Mountains,1,000 m. The mines of the Enna and Caltanissetta districts were part of a leading sulphur-producing area throughout the 19th century, Sicily and its surrounding small islands have some highly active volcanoes. Mount Etna is the largest active volcano in Europe and still casts black ash over the island with its ever-present eruptions and it currently stands 3,329 metres high, though this varies with summit eruptions, the mountain is 21 m lower now than it was in 1981. It is the highest mountain in Italy south of the Alps, Etna covers an area of 1,190 km2 with a basal circumference of 140 km. This makes it by far the largest of the three volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius. In Greek Mythology, the deadly monster Typhon was trapped under the mountain by Zeus, Mount Etna is widely regarded as a cultural symbol and icon of Sicily. The Aeolian Islands in the Tyrrhenian Sea, to the northeast of mainland Sicily form a volcanic complex, the three volcanoes of Vulcano, Vulcanello and Lipari are also currently active, although the latter is usually dormant

Gloster Gauntlet
–
The Gloster Gauntlet was a British single-seat biplane fighter of the RAF, designed and built by Gloster Aircraft in the 1930s. It was the last RAF fighter to have an open cockpit, the Gloster S. S.18 first flew in January 1929. On testing the S. S.19, the Air Ministry placed an order for 24 aircraft in September 1933, the order was followed up with more for the revised Gauntlet Mk. This new model used a construction method based on that used by Hawker following Hawkers takeover of Gloster, as this was much easier to build. A total of 204 Mk IIs were produced in the UK, I first entered service with No 19 Squadron at RAF Duxford in May 1935. The Gauntlet proved successful and popular in service, being 56 mph faster than the aircraft it replaced. The Gauntlet was the fastest aircraft in the RAF from 1935 to 1937, the Gauntlet Mk II entered service with 56 Squadron and 111 Squadron in May 1936, a further six squadrons being re-equipped with the Gauntlet by the end of the year. At the height of its career, the Gauntlet equipped a total of 14 Squadrons of RAF Fighter Command, No.32 Squadron RAF Gauntlets were used in early trials of ground direction of fighters by radar. Gauntlets were also shipped to the Middle East, equipping three RAF squadrons.3 Sqn RAAF in the Middle East when Italy declared war in 1940 and these were briefly used for ground-attack operations against the Italians before being retired from operations owing to maintenance problems. Gauntlets continued in use for meteorological flights until 1943, seventeen Gauntlets IIs were licence-produced in Denmark, while 25 ex-RAF machines were supplied by South Africa as support to Finland in 1940 as a result of the Winter War. Already obsolete, they were used as advanced trainers by the Finns, the Finnish nickname for the Gauntlet was Kotletti. The aircraft was fitted with a 450-hp Bristol Mercury IIA radial piston engine, SS. 18A, The SS.18 was fitted with a 480 hp Bristol Jupiter VIIF radial piston engine. SS. 18B, The SS.18 was later fitted with a 560 hp Armstrong Siddeley Panther III radial piston engine, SS.19, Single-seat prototype, fitted with a Bristol Jupiter radial piston engine. SS. 19A, The SS.19 was later fitted with two wheel spats and a single spatted tailwheel, SS. 19B, Single-seat prototype, fitted with a 536 hp Bristol Jupiter VIS radial piston engine. Gauntlet Mk I, Single-seat fighter aircraft for the RAF,24 built, Gauntlet Mk II, Single-seat fighter aircraft, modified version of the Gauntlet Mk I,221 built

Gloster Gladiator
–
The Gloster Gladiator is a British-built biplane fighter. It was used by the Royal Air Force and the Fleet Air Arm and was exported to a number of air forces during the late 1930s. It was the RAFs last biplane fighter aircraft and was rendered obsolete by newer monoplane designs even as it was being introduced, though often pitted against more formidable foes during the early days of the Second World War, it acquitted itself reasonably well in combat. The Gladiator saw action in almost all theatres during the Second World War, with a number of air forces. The RAF used it in France, Norway, Greece, the defence of Malta, the Middle East, the South African pilot Marmaduke Pat Pattle was the top Gladiator ace with 15 victories. However, the Goshawk engine proved to be unreliable and unsuited to use on fighter aircraft, a further stumbling point for many of the submitted designs was the placement of the machine gun breeches in arms reach of the pilot. At the same time, the development of fighters such as the Hawker Hurricane and Supermarine Spitfire cast doubt over the future viability of the requirement altogether. Gloster recognised that, instead of developing a design from scratch. Development of what would become the Gladiator began as a venture, internally designated as the SS.37. Folland soon identified various changes to increase the aircrafts suitability to conform with the demands of the specification. The Bristol Mercury M. E.30 radial engine, capable of generating 700 hp of thrust, was selected to power the SS.37, another design choice was the fitting of a cantilever main undercarriage which incorporated Dowty internally-sprung wheel struts. In Spring 1934, Gloster embarked on the construction of a single SS.37 prototype, on 12 September 1934, the SS.37 prototype conducted its maiden flight, piloted by Gloster chief test pilot Gerry Sayer. Initially powered by a 530 hp Mercury IV engine, the prototype was quickly reequipped with a more powerful 645 hp Mercury VIS engine, during flight tests, the prototype attained a top speed of 242 mph while carrying the required four.303 in machine guns. On 3 April 1935, the prototype was transferred to the Royal Air Force, receiving the designation K5200, K5200 was later used to trial modifications for production aircraft, such as the addition of a sliding hood for the pilot. In June 1935, production plans for the aircraft were proposed and this culminated in an initial order for 23 aircraft. On 1 July 1935, the aircraft received the name Gladiator. Manufacturing of the Gladiator was started at Glosters Hucclecote facility, production of the initial batch was performed simultaneously, leading to many aircraft being completed around the same time. On 16 February 1937, K6129, the first production Gladiator, was accepted by the RAF, on 4 March 1937, K6151

Hawker Hurricane
–
The Hawker Hurricane is a British single-seat fighter aircraft of the 1930s–1940s that was designed and predominantly built by Hawker Aircraft Ltd for the Royal Air Force. In late 1934, the Air Ministry placed an order for Hawkers Interceptor Monoplane, on 6 November 1935, the prototype Hurricane, K5083, performed its maiden flight. In June 1936, the Hurricane was ordered into production by the Air Ministry, the Hurricane was rapidly procured prior to the outbreak of the Second World War in September 1939, by which point, the RAF operated a total of 18 Hurricane-equipped squadrons. It is perhaps best known for its contribution to Britains home defences during the Battle of Britain, the Hurricane evolved through several versions and adaptations, resulting in a series of aircraft which acted as fighters, bomber-interceptors, fighter-bombers and ground support aircraft. By the end of production in 1944, in excess of 14,583 Hurricanes had been completed, at the time, there was an institutional reluctance towards change within the Air Staff, according to aviation author Francis K. In 1934, the British Air Ministry issued Specification F. 7/30 in response to demands within the Royal Air Force for a new generation of fighter aircraft. Earlier, during 1933, British aircraft designer Sydney Camm had conducted discussions with Major John Buchanan of the Directorate of Technical Development on a monoplane based on the existing Fury. Camms initial submission in response to F. 7/30, the Hawker P. V.3, was essentially a version of the Fury biplane. However, the P. V.3 was not among the proposals which the Air Ministry had selected to be constructed as a government-sponsored prototype, after the rejection of the P. V. By January 1934, the detail drawings had been finished. In August 1934, a scale model of the design was produced and dispatched to the National Physical Laboratory at Teddington. A series of wind tunnel tests confirmed the aerodynamic qualities of the aircraft were in order and this time, the Ministrys response was favourable, and a prototype of the Interceptor Monoplane was promptly ordered. In November 1934, the Air Ministry issued Specification F. 5/34 which, drawing on the work of Squadron Leader Ralph Sorley, however, by this time, work had progressed too far to immediately modify the planned four-gun installation. In July 1935, this specification was amended to include installation of eight guns, ground testing and taxi trials took place over the following two weeks. On 6 November 1935, the prototype K5083 took to the air for the first time at the hands of Hawkers chief test pilot, Flight Lieutenant George Bulman. Bulman was assisted by two pilots in subsequent flight testing, Philip Lucas flew some of the experimental test flights. As completed, the prototype had been fitted with ballast to represent the aircrafts armament prior to the acceptance of the final multi-gun wing armament. In early 1936, the prototype was transferred to RAF Martlesham Heath, Suffolk, in the course of further testing, it was found that the Hurricane had poor spin recovery characteristics, in which all rudder authority could be lost due to shielding of the rudder

Curtiss P-40 Warhawk
–
The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production, the Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war. P-40 Warhawk was the name the United States Army Air Corps and after June 1941, USAAF-adopted name for all models, making it the official name in the U. S. for all P-40s. The British Commonwealth and Soviet air forces used the name Tomahawk for models equivalent to the P-40B and P-40C, P-40s first saw combat with the British Commonwealth squadrons of the Desert Air Force in the Middle East and North African campaigns, during June 1941. However, between 1941 and 1944, the P-40 played a role with Allied air forces in three major theaters, North Africa, the Southwest Pacific, and China. It also had a significant role in the Middle East, Southeast Asia, Eastern Europe, Alaska, the P-40s performance at high altitudes was not as important in those theaters, where it served as an air superiority fighter, bomber escort and fighter-bomber. The P-40 offered the advantage of low cost, which kept it in production as a ground-attack aircraft long after it was obsolete as a fighter. On 14 October 1938, Curtiss test pilot Edward Elliott flew the prototype XP-40 on its first flight in Buffalo, the first prototype placed the glycol coolant radiator in an underbelly position on the fighter, just aft of the wings trailing edge. USAAC Fighter Projects Officer Lieutenant Benjamin S. Kelsey flew this prototype some 300 miles in 57 minutes, hiding his disappointment, he told reporters that future versions would likely go 100 miles per hour faster. Kelsey was interested in the Allison engine because it was sturdy and dependable, Curtiss engineers worked to improve the XP-40s speed by moving the radiator forward in steps. Seeing little gain, Kelsey ordered the aircraft to be evaluated in a NACA wind tunnel to identify solutions for better aerodynamic qualities, from 28 March to 11 April 1939, the prototype was studied by NACA. Based on the data obtained, Curtiss moved the glycol coolant radiator forward to the chin, other improvements to the landing gear doors and the exhaust manifold combined to give performance that was satisfactory to the USAAC. Without beneficial tail winds, Kelsey flew the XP-40 from Wright Field back to Curtisss plant in Buffalo at an speed of 354 mph. Further tests in December 1939 proved the fighter could reach 366 mph, an unusual production feature was a special truck rig to speed delivery at the main Curtiss plant in Buffalo, New York. The rig moved the newly built P-40s in two components, the main wing and the fuselage, the eight miles from the plant to the airport where the two units were mated for flight and delivery. The P-40 was conceived as an aircraft and was agile at low and medium altitudes. At medium and high speeds it was one of the tightest-turning early monoplane designs of the war, and it could out turn most opponents it faced in North Africa and the Russian Front. In the Pacific Theater it was out-turned at lower speeds by the lightweight fighters A6M Zero, the American Volunteer Group Commander Claire Chennault advised against prolonged dog-fighting with the Japanese fighters due to speed reduction favouring the Japanese
