Description:

Ye-152-1 experimental supersonic interceptor

Not waiting finalization of Ye-150’s trials,
the OKB-156 (Mikoyan-Gurevich Design Bureau) had started its work on Ye-152 and
Ye-152A modifications, which were very similar and differed only in the rear
fuselage section. On March 16, 1961 the initial flight-trials of
Ye-152-1 (first Ye-152 prototype) begun. According to the technical
specification, this heavy fighter had to be able to intercept and destroy air
targets, flying at a speed of 2,500 km/h at an altitude of 20,000 m. The
aircraft wing area was increased to 40 m2, the leading edge sweep was decreased
to 47 °, wing tips had pylons for K-9 missile suspension.The air intake design was similar to those of
Ye-152A. On the cylindrical base of the cone, there was a perforated zone. The
cone was static, having adjustable cowling in flight.From April 21, 1961 to September 11, 1962 up to
67 flights were performed, 5 of them – with mock-ups of K-9 missiles. The
maximum speed with missiles reached at an altitude of 16,200 m was 2,650 km/h.
The aircraft power plant consisted of one enhanced R-15-300 jet engine.The
Ye-152-1, registered with the FAI as Ye-166, set 3 world records for speed and
flight altitude.
