Mikoyan-Gurevich Ye-166


Development of the Ye-152 series of interceptors was stopped as a result of the OKB 's preoccupation with the Ye-155P (MiG-25P), but the remaining prototype was completed for high-speed research as the Ye-152M with an R-15B-300 engine providing an afterburning thrust of 10210kg. This aircraft established (as the Ye-166) an absolute speed record over a 100km closed-circuit of 2601km/h on 7 October 1961, and an absolute speed record of 2681km/h on 7 July 1962.

The Ye-166 was used for exploration into the structural and aerodynamic requirements of flight at speeds of more than 1864 mph (3000 km/h).
