The Ye-152M is a part of the Ye-150 Family of heavy interceptors prototypes for the Soviet Union.

To fulfil the needs of the Protivo-Vozdushnaya Oborona for a heavy interceptor to carry out automatic interceptions, the MiG bureau had developed a range of large fighter aircraft starting with the swept wing I-3 series (a.k.a. I-380, I-410 and I-420), followed by the I-7 and the I-75. The MAP ordered the Mikoyan OKB to build prototypes of the new interceptor, to be armed with either K-6, K-7, K-8, K-9, unguided rockets, or an aimable twin cannon installation.

The first prototype was the Ye-150 which first flew on July 8, 1960. The Ye-150 suffered from multiple setbacks in maintenance and engine reliability, however the performance of the prototype was impressive which lead to the program's continued development.

The Ye-152 prototypes were similar in design to the ye-150 but contained a newer engine that was supposed to be more reliable, this however wasn't so as it still retained major reliability issues. However the two planes went on to perform world record flights for the time. The wings were cropped in order for the plane to mount the intended K-80 or K-9 missiles. However with the cancellation of the K-9 the programs was ensured it would never see production. Ye-152-1 performed the world record flights under the registration Ye-166. Ye-152-2 was returned to MiG to receive modifications that would result in the Ye-152M

Ye-152M modifications included a new engine, the R-15-300 engine fitted with an axisymmetric convergent-divergent nozzle, and a set of canards by the cockpit. After initial test flights the canards were removed leaving the mounting points behind. After being used as a testing platform for newer engines and weapon control systems, the plane was retired to the Central Air Force Museum at Monino. While there, Ye-152M was intentionally given a new paintjob bearing the designation E-166 (Ye-166) despite not being the real Ye-166 (Ye-152-1). It also has three red stars painted on it to signify the records set by the real Ye-166.

This plane here is based off of the Ye-152M in its initial form after the modifications and before the canards were removed. Its armed with two
K-80/R-4 long range missiles (the most frequent armament seen on this plane).
