Description:

Ye-152A Soviet twin-engined interceptor

The Ye-152 and Ye-152A were developed in the late 50’s from the Ye-150 interceptor by OKB-156 Design team.Due to the fear of possible malfunctions in the Ye-150’s R15-300 jet engine, the designers created second prototype under designation Ye-152A, powered by two  R11F-300 engines, each having a maximum thrust of 3880 kgf or 5740 kgf on afterburner regime.The whole groundwork of the second E-150 was used for the construction of E-152A. It’s wing, vertical stabilizer and fin have the same geometrical dimensions and construction as the E-150 ones. The nose fuselage section was identical either, but the air intake cone of Ye-152A was not adjustable in comparison to E-150. The air intake regime was controlled by moving back and forward the front shell rings.The Ye-152A was designed for carrying K-9 guided missiles, using new “CP-1” radar system, created by “Almaz” Design Bureau.In connection with the installation of the reliable  R11F-300 engines, the Ye-152A modification had been prepared for the test before all E-150 and E-152 aircrafts.The maiden flight of Ye-152A was made on July 10, 1959 by G.K. Mosolov on the controls. Since the finalization of the flight tests in August 1960, the plane has performed in overall – 55 flights, and only 2 flights carrying dummies of K-9 missiles.The Ye-152A was demonstrated on public in 1961 at the Tushino airfield, receiving the attention of NATO experts, giving him the reporting name –“Flipper “(fin).
