Unmanned aerial vehicle M-21 is a highly maneuverable machine that was radio-controlled. The aircraft target was the most popular and full-scale simulator flying device. The development unit M-19 engaged OKB and LII KAI, development was carried out on the basis of the existing models of fighter MiG-21PF.

Conversion of the aircraft took place on the basis of ARZ. External parameters and view almost not been changed, so distinguished from the base model by their appearance is almost impossible.

The set of equipment:

  • Autopilot AP-17 type and automatic flight control. All of this is located in the forward section of the aircraft.
  • Cassettes with traps such as IR.
  • Devices for recording the number of hits and misses.
  • Equipment changes trajectory.
  • To set the day monitoring the tracer.

Subsequently, for the refit began to use airplanes of the MiG-21 PFM type. Due to this, with 1973, the combat fleet was replenished with targets with the designation M-21M. With take-off, the mass of the device reached 8,4 tons, yet the car could develop a speed of 1800 km / h at an altitude of 11 kilometers. The use of the device was possible at an altitude of 50 meters and up to 14,4 kilometers. Use the machine M-21 it was possible for 106 minutes of flight. Preparation for takeoff took 40 minutes of time. Maneuverability was quite high-quality and withstood the overload in 8,5. Take-off and landing of an unmanned vehicle M-21 are possible from both concrete and ground runways.
