To meet the requirements of the Soviet Air Defense Forces for a large interceptor aircraft that was capable of automatic interceptions, the manufacturing company Mikoyan-Gurevich developed several heavy fighter aircraft. The Ye-152 had two prototypes designated as the Ye-152-1 and Ye-152-2.

The Ye-152s were equipped with upgraded R-15-300 engines from Tumansky. However, aircraft reliability was still a problem, with just a few developments flying, tests of weapons system were set and world record flights were accomplished. The engine’s inefficient capability and the abortion of the proposed K-9 air-to-air missile or Uragan-5B automatic weapon system led the Ye-152 development to an end.

In 1961 and 1962, world record flights were performed by the Ye-152-1. It was registered as the Ye-166 with the World Aeronautical Federation. The Ye-152-2 was put back to the manufacturing company to get it converted into the Ye-152M, a variant designed with mini canards on both sides of the fuselage.

The 152-2 was powered by a single Tumansky R-15-300 turbojet engine. It has a five-stage axial compressor, a single-stage turbine, and a type 67 grade oil system. It is an afterburning turbojet with a maximum thrust rate of 22,400 lbf.

The Ye-152 has an external length of 19.66 meters, an external height of 3 meters, a tail height of 4.75 meters, and a fuselage diameter of 1.4 meters. It featured a cropped delta wings with a wingspan of 8.8 meters and a wing area of 40.02 square meters to allow the mounting of large missiles on wingtip launchers. The wheelbase is 6 meters.

The prototype has a maximum speed of 1,640 knots at 50,525 feet and a travel range of 790 nautical miles. The service ceiling is 74,410 feet and the rate o climb is 12,300 feet per minute. It has a maximum takeoff weight of 14,350 kg and an empty weight of 10,900 kg.  The maximum payload is 3,450 kg.

The Ye-152 was intended to be loaded with 2×23 mm Afanasev Makarov AM-23 autocannons in an aimable mount and various air-to-air missiles such as K-6, K-7, K-8, and K-9.
