Development of jet-lift V/STOL aircraft made it desirable also to develop supporting vehicles able to supply the dispersed and frequently moved operating bases with food, fuel and munitions, and also to provide defence. Yakovlev produced this remarkable project for a complete flying SAM (surface-to-air missile) system.

The huge box-like fuselage, some 49m long, carried six V-750 (11D) or V-755 (20D) [ASCC name 'Guideline'] missiles ready to fire on their launchers, plus reloads and the supporting radars and auxiliary power supplies. It was lifted by six six-blade rotors, each driven by four turboshaft engines. The requirement evaporated with failure to put land-based V/STOLs into service.
