A "BizjEt” Derivative of the MiG 25P
On the MiG-25PU and MiG-25RU trainers, unlike the MiG-23UB, the flight instructor sat in the front cockpit
the main specifications required maximum commonality between the bizjet and the MiG-25P interceptor. In fact, only the forward fuselage had to be modified. This part of the aircraft was to be significantly lengthened, its master cross-section increased, and the cockpit located still farther forward than that in the front of the MiG-25PU trainer.
The cabin was planned to accommodate six passenger seats in a straight line along a narrow aisle with the entrance door on the left side of the fuselage, just behind the cockpit. This way it could quickly be converted into a cargo hold. The master cross-section increase offered another advantage: it increased the fuel capacity and consequently the range to 3,000-3,500 km (1,860-2,175 miles) at cruising speeds of 2,500 km/h or Mach 2.35 (1,350 kt).
