EPOS (105.11) – Experimental manned space aircraft.
I-1 – The I-1, officially called I-370, was an experimental frontal fighter, using the same technology and wing as the parallel MiG-19 series, but powered by a single, powerful engine. Performance was disappointing, and the type given an uprated engine a different wing, then being called the I-2. Performance was still below specifications, and the design was again modified to become the I-3, which was never flown.
I-2 – Modification of the I-1 with greater wing sweep, and a more powerful version of the Klimov VK-7 engine. Performance was still disappointing. 1955.
I-3 – Frontal fighter, developed in parallel with the I-1. It resembled a scaled up Ye-2: tubular fuselage, swept wings. It did not fly because the engine was not ready. A development, the I-3U was also known as the U-5. It too was never flown.
I-5 – I-3.
I-7 – The I-7 interceptor was developed from the never flown I-3 and I-5. It was re engined, and wing sweepback was slightly reduced.
I-20 / I-200 – MiG-1.
I-63 – MiG-3.
I-75 – This was a rebuild of the I-7U with a new engine and forward fuselage, having a circular intake with a three-shock nose cone containing radar. The competing Su-9 was selected to fill the interceptor requirement.
I-210 – This was an adaptation of the MiG-3 to use the M-82 radial engine instead of the discontinued Mikulan AM-35. The I-210 had aerodynamic problems, which resulted in excessive drag, vibration and handling problems. After TsAGI testing, redesign was applied and the aircraft became the I-211.
I-211 – The I-211 was a development of the I-210, itself an attempt to revive the MiG-3 by substituting the M-82 radial for the abandoned AM-35A engine. The I-211 embodied the modifications recommended by the TsAGI, and proved excellent. It came too late, the La-5 was already in production and the MiG-3 had been phased out.
I-225 – Fifth prototype of the I-220 (I-221, I-222, I-224, I-225) series. The I-220 was a specialized high-altitude interceptor of advanced design. It had a pressure cabin, was well-armoured, carried heavy armament, and had a turbo-supercharged engine. But the expected high-altitude threat did not materialize, and the I-220 was not produced.
I-230 – First prototype of the I-230 series.
I-231 – Second prototype of the I-230 series. The I-230 was a less advanced backup programme for the I-220 high-altitude fighter, without turbochargers or pressure cabin. The I-230 was based on the MiG-3, but longer and mostly of wooden construction. It retained the AM-35 engine, which was no longer available, and only 10 were built. The I-231 was powered by the AM-39, but was lost in a crash, and development was halted.
I-250 – MiG-13.
I-270 (ZH) – The I-270(ZH) was a rocket-powered target defense fighter, with straight wings and a T-tail. Both prototypes destroyed, and the programme canceled.
I-300 – MiG-9.
I-301 – The I-301T was a two-seat trainer development of the MiG-9.
I-305 – Version of the MiG-9 with two Lyulka TR-1 engines.
I-307 – The MiG-9F, a development with RD-21 engines.
I-308 – The MiG-9FR.
I-310 – MiG-15.
I-320 – Twin-engined all-weather fighter. The engines were fitted in tandem, one exhausting just after the wing, the other under the tail. A circular nose intake was used with a radar cone on the upper lip, and side-by-side seating for the crew members. The Yak-25, designed to a more advanced requirement, was preferred.
I-330 – MiG-17.
I-340 – The I-340 was a development of the MiG-17 with two 2200kg Mikulin AM-5 engines. This was the engine installation of the I-360 or MiG-19.
I-350 – This was a single-seat fighter with a Lyulka TR-3 engine, similar in general outline to the MiG-17, but with a highly swept wing. It was designed for sustained supersonic flight. The TR-3 was unreliable, and the I-350 was rebuilt with paired Mikulin AM-5 engines.
I-360 – The I-360 was a derivative of the I-350, designed from the outset for two Mikulin AM-5 engines. It became the prototype of the MiG-19.
I-370 – I-1.
I-380 – I-3.
I-410 – I-3.

SM-1 – I-340.
SM-2 – I-360.
SM-7/SM-9 – Prototype of the MiG-19.
SM-10 – Experimental MiG-19 version with flight refuelling probe.
SM-12 – The SM-12 was a development of the MiG-19, intended as a back-up for the MiG-21 program. The original intake was replaced by a sharp-edged circular one with a radar nose cone, the guns were deleted and missile armament installed. Later it also adopted a different engine, and the final modification included a ventral rocket engine pack.
SM-30 – Experimental ramp-launched MiG-19 version (with additional PRD-22 rocket booster).
SM-50 – Experimental version of the MiG-19 with a 3,200 kg.U-19 rocket engine.
SM-51 / SM-52 – Development of the SM-50.
SN – Experimental attack aircraft, a version of the MiG-17 with lateral intakes. This made room in the nose for three 23mm cannon, two to starboard and one to port, one a variable elevation mounting in the nose. It was abandoned because of developments in missiles.
SP-1 – All-weather version of the MiG-15.
SP-2 – All-weather version of the MiG-17.
SR-2 – Experimental version of the MiG-17 with a 3,100 kg. Klimov VK-5F engine. Intended as tactial reconnaissance aircraft.
SU – Ground-attack derivative of the MiG-15, armed with paired 23mm cannon in articulated mountings. Abandoned. 1951.
Type 7.01 – Distant Interceptor.
Type 301 – Hypersonic recon / bomber.
Ye-1 – Single-seat jet fighter design. When the more powerful AM-9 engine replaced the AM-5 in the design stage, the type was renamed Ye-2.
Ye-2 – Single-seat jet fighter. The fuselage was very similar to that of the early MiG-21, but the Ye-2 had a swept wing instead of a delta. NATO thought that this aircraft was in service as the MiG-21 and assigned the codename ‘Faceplate’. Actually it was the delta-winged Ye-5 that entered production as the MiG-21. Two built, the second one with the 5,100 kg. Tumansky AM-11 engine.
Ye-4 – Tailed-delta fighter prototype. Performance was about equal to the Ye-2 which was very similar but had a plain swept wing. Another prototype was ordered, the Ye-5, from which the production MiG-21 was derived. The Ye-4 was powered by an AM-9 engine. 1955.
Ye-5 – Development of the Ye-4 with the more powerful AM-11 engine, built in parallel with the second (and similarly powered) Ye-2. 1956. Development continued as the Ye-6.
Ye-6 – Pre-series version of the early MiG-21, development of the Ye-5. Some were fited, in the same way as some Ye-152s, with small canard foreplanes.
Ye-7 – Prototype of the MiG-21PF.
Ye-8 – Experimental fighter. The Ye-8 was a single-seat, single-engined aircraft with a delta wing and tail surfaces similar to that of the MiG-21, but also with canard foreplanes. The fuselage was similar to that of the X-31 or Eurofighter 2000, with a rectangular variable geometry intake under the front fuselage, ahead of the wing roots.
Ye-9 – Prototype of the MiG-21PFMA.
Ye-23DPD – STOL fighter of tailed delta configuration, fitted with two lift engines in the forward fuselage. The variable geometry concept of the Ye-23IG was preferred.
Ye-23IG – Prototype of the MiG-23.
Ye-50 – The Ye-50 was a version of the Ye-2 ‘Faceplate’ fitted with a small jet engine and a rocket engine at the base of the tail fin. It was intended as a point defense interceptor. Top speed was Mach 2.3, and the Ye-50 may have been considered as a possible Lockheed U-2 interceptor. After three prototypes, a production batch of 50 was ordered, but these were not built because the rocket engines were unavailable.
Ye-150 – Technology demonstrator for an all-weather interceptor. The Ye-150 was a tailed delta, optimized for the short-range interceptor role, possibly as an U-2 interceptor. One built. The operational version would have been the Ye-152. The Ye-150 was also intended to test the Tumansky R-15 engine.
Ye-152 – The Ye-152 was an operational interceptor development of the Ye-150. The first Ye-152A had two R-11 engines because the large R-15 was still in development, and in consequence it flew before the Ye-150 it was derived from. The Ye-152/1 and Ye-152/2, which were powered by a single R-13, flew later. The Ye-152 was seen in Tushino in 1961, hence the assignment of a NATO code name, but it never entered service. Mikoyan chose to concentrate on the development of the Ye-155 (MiG-25).
