The Mikoyan-Gurevich MiG-15 (Russian: Микоян и Гуревич МиГ-15) was a jet fighter developed for the USSR by Artem Mikoyan and Mikhail Gurevich. The MiG-15 was one of the first successful swept-wing jet fighters, and it achieved fame in the skies over Korea, where early in the war, it outclassed all straight-winged enemy fighters in daylight. The MiG-15 also served as the starting point for development of the more advanced MiG-17 which was still an effective threat to supersonic American fighters over North Vietnam in the 1960s. The MiG-15 is believed to have been the most widely produced jet aircraft ever made, with over 12,000 built. Licensed foreign production perhaps raised the total to over 18,000.The MiG-15 is often mentioned along with the North American F-86 Sabre in lists of the best fighter aircraft of the Korean War and in comparison with fighters of other eras.


-Design and development

Most early jets were designed like piston-engined fighters with straight wings, limiting their high speed performance. German research during World War II had shown swept wings would perform better at transonic speeds, and Soviet aircraft designers were quick to take advantage of this information. There are claims of Artem Mikoyan and Mikhail Gurevich (lead designers of the "MiG" bureau) being heavily influenced by the Focke-Wulf Ta 183. The abortive late-war German jet had swept wings and bore a resemblance to the later MiG-15, but the two aircraft are different in structure and general design. The Soviets did seize plans and prototypes for the Ta-183, but the majority of Focke-Wulf engineers (in particular, Hans Multhopp, who led the Ta-183 development team) were captured by Western armies; therefore, it could be argued that the MiG-15 design team drew some limited inspiration from the Ta-183, but there is insufficient evidence to prove it was heavily influenced. Currently, many sources claim that the MiG-15 is an original design benefiting from German research, but conceived, designed, engineered, and produced by the Soviets.
The unusual MiG-8 Utka experimental canard aircraft, built right at the conclusion of World War II by the MiG design bureau, is said to have also been a major influence in the use of swept wings on later Mikoyan designs.
By 1946, Soviet designers were to power them. Soviet aviation minister Mikhail Khrunichev and aircraft designer A. S. Yakovlev suggested to Premier Joseph Stalin the USSR buy advanced jet engines from the British. Stalin is said to have replied, "What fool will sell us his secrets?"
However, he gave his consent to the proposal and Mikoyan, engine designer Vladimir Klimov, and others travelled to the United Kingdom to request the engines. To Stalin's amazement, the British Labour government and its pro-Soviet Minister of Trade, Sir Stafford Cripps, were perfectly willing to provide technical information and a license to manufacture the Rolls-Royce Nene. This engine was reverse-engineered and produced as the Klimov RD-45, subsequently incorporated into the MiG-15.Rolls-Royce later attempted to claim £207 million in license fees, without success.

In the interim, on 15 April 1947, the Council of Ministers issued decree #493–192, which ordered the Mikoyan OKB to build two prototypes for a new jet fighter. As the decree called for a first flight as soon as December, designers at OKB-155 fell back on an earlier troublesome design, the MiG-9. The MiG-9 suffered from an unreliable engine and control problems; the first would be solved by the excellent new Klimov engine, and to solve the second, the designers began experimenting with swept wings and redesigning the tail. The resulting prototypes were designated as I-310.
The I-310 was a clean, swept-wing fighter with 35° sweep in wings and tail, and exceptional performance, with a top speed of over 1,040 km/h (650 mph). Its primary competitor was the similar Lavochkin La-168. After evaluation, the MiG design was chosen for production. Designated MiG-15, the first production example flew on 31 December 1948. It entered Soviet Air Force service in 1949, and would subsequently receive the NATO reporting name "Fagot." Early production examples had a tendency to roll to the left or to the right due to manufacturing variances, so aerodynamic trimmers called "nozhi" (knives) were fitted to correct the problem, the knives being adjusted by ground crews until the aircraft flew correctly.
An improved variant, the MiG-15bis ("second"), entered service in early 1950 with a Klimov VK-1 engine, an improved version of the RD-45/Nene, plus minor improvements and upgrades.[6] Visible differences were a headlight in the air intake separator and horizontal upper edge airbrakes. The 23 mm cannons were placed more closely together in their undercarriage. Some "bis" aircraft also adopted under-wing hardpoints for unguided rocket launchers or 50–250 kg (110–551 lb) bombs. Fighter-bomber modifications were dubbed "IB", "SD-21", and "SD-5". About 150 aircraft were upgraded to SD-21 specification during 1953–1954. An unknown number of aircraft were modified to "IB" specification in the late 1950s.
The MiG-15 arguably had sufficient power to dive at supersonic speeds, but could not do so because it did not have an "all-flying" tail. As a result, the pilot's ability to control the aircraft deteriorated significantly as it approached Mach 1. Later MiGs would incorporate all-flying tails.
The MiG-15 was originally intended to intercept American bombers like the B-29. It was even evaluated in mock air-to-air combat trials with a captured U.S. B-29, as well as the later Soviet B-29 copy, the Tu-4 "Bull". To ensure the destruction of such large bombers, the MiG-15 carried cannons: two 23 mm with 80 rounds per gun and a single 37 mm with 40 rounds. These weapons provided tremendous punch in the interceptor role, but their limited rate of fire and relatively low velocity made it more difficult to score hits against small and maneuverable enemy jet fighters in air-to-air combat. The 23 mm and 37 mm also had radically different ballistics, and some United Nations pilots in Korea had the unnerving experience of 23 mm shells passing over them while the 37 mm shells flew under. The cannons were fitted into a neat pack that could be winched down out of the bottom of the nose for servicing and reloading, in principle allowing a pre-prepared pack to be switched for rapid turnaround. (Some sources mistakenly claim the pack was added in later models.)
A variety of MiG-15 variants were built, but the most common was the MiG-15UTI (NATO reporting name "Midget") two-seat trainer.[citation needed] Because Mikoyan-Gurevich never mass-produced the transition training versions of the later MiG-17 or MiG-19, the MiG-15UTI remained the sole Warsaw Pact advanced jet trainer well into the 1970s, the primary training role being fulfilled exclusively by Czechoslovak Aero L-29 Delfin and the L-39 Albatros jet trainers (save for Poland, which used their indigenous TS-11 Iskra jets). While China produced two-seat trainer versions of the later MiG-17 and MiG-19, the Soviets felt that the MiG-15UTI was sufficient for their needs and did not produce their own trainer versions of those aircraft.

Operational history

The MiG-15 was widely exported, with the People's Republic of China receiving MiG-15bis models in 1950. Chinese MiG-15s took part in the first jet-versus-jet dogfights during the Korean War. The swept-wing MiG-15 quickly proved superior to the first-generation, straight-wing jets of western air forces such as the F-80 and British Gloster Meteor, as well as piston-engined P-51 Mustangs and F4U Corsairs with the MiG-15 of First Lieutenant Semyon Fiodorovich Jominich scoring the first jet-vs-jet victory in history when he bagged the F-80C of Frank Van Sickle, who died in the encounter (the USAF credits the loss to the action of the North Korean flak).[7][unreliable source?] Only the F-86 Sabre, with its highly trained pilots, was a match for the MiG.
Its baptism of fire occurred during the last phases of the Chinese Civil War (1946–49). During the first months of 1950, the aviation of Nationalist China attacked from Taiwan the communist position in continental China, especially Shanghai. Mao Zedong requested the military assistance of the USSR, and the 50th IAD (Истребительная Авиадивизия, ИАД; Istrebitelnaya Aviadiviziya; Fighter Aviation Division) equipped with the MiG-15bis was deployed south of the People's Republic of China. On 28 April 1950, Captain Kalinikov shot down a P-38 of the Kuomintang, scoring the first aerial victory of the MiG-15. Another followed on 11 May, when Captain Ilya Ivanovich Schinkarenko downed the B-24 Liberator of Li Chao Hua, commander of the 8th Air Group of the nationalist Air Force.

Production

The USSR built around 12,000 MiG-15s in all variants. It was also built under license in Czechoslovakia (as the S-102 and S-103) and Poland (as the Lim-1 and Lim-2, and two-seat SB Lim-1 and SB Lim-2).
In the early 1950s, the Soviet Union delivered hundreds of MiG-15s to China, where they received the designation J-2. The Soviets also sent almost a thousand MiG-15 engineers and specialists to China, where they assisted China's Shenyang Aircraft Factory in building the MiG-15UTI trainer (designated JJ-2). China never produced a single-seat fighter version, only the two-seat JJ-2.[49]
The designation "J-4" is unclear; some sources claim Western observers mistakenly labelled China's MiG-15bis a "J-4", while the PLAAF never used the "J-4" designation. Others claim "J-4" is used for MiG-17F, while "J-5" is used for MiG-17PF.[50] Another source claims the PLAAF used "J-4" for Soviet-built MiG-17A, which were quickly replaced by license-built MiG-17Fs (J-5s).[51] What is certain, is that the service lives of the J-2 and J-4 in the PLAAF were short, as they were quickly replaced by the more capable J-5 and J-6.

Assuming that WoWp is WW1 to Korea (in terms of aircraft era) it is quite likely that the mig15 will be either tier 8 or so (assuming that 9 and 10 are experimental, psycho planes) and therefore i agree with the others that are questioning your simple 'no, period' Arbiter.

Especially since the release of the US Tech Tree make it almost certain the 15 will be the Russian Tier 10.

Swept wings were really a structural way of achieving a thinner wing.  You could make it the same thickness as an unswept wing, but the sweep would make it broader in chord, reducing the thickness/chord ratio.  Until they got better materials/structures, this gave a simpler way of achieving the speed required and still retain the strength needed to fight.

One of the US test pilots who did the testing on the MiG 15 to establish its performance was none other than Chuck Yeager.  At very high altitudes, the plane could "snake", especially when the guns were fired, Yeager commented the spread was about the distance of the B36's wingspan.

Well its not from ww1 its from 1929 to korean war. And Mig15 will be a tier 10 warplane, but that does not means that WG wont add more jet planes since every nation will end with 100 warplanes.

if MiG-15 is tier 8 or so, then the La-15 should be aswell as it is from the same period (even a little earlier)...

I must agree however that many aircraft of even after the Korea War would have been fun in this game. Iam thinking of MiG-19 or F-100 for example (of course interceptors like F-102 would totaly ruin the game). So reserving the Tier 9 and 10 for somthing a little more modern won't be bad I guess... It is a shame how in WoT they blocked the Tier 10 with M48 and T-62 wile T-64A, M60, AMX-30 and leopard 1 would be completely playable without changing the game. I hope they don't do same "mistake" here.
