The Yakovlev VVP-6 was designed as a giant VTOL support platform that would work in coordination with VTOL jets, such as the Yakovlev Yak-38.
Among the many functions envisioned for this vehicle was the transportation of food, fuel, and munitions. The huge, box-like design was to have been 49m long. In one version it was capable of carrying a complete SAM missile system, including six S-75 Dvina (NATO reporting name SA-2 Guideline) missiles with launchers mounted on the craft's upper surface. Reloads and supporting radars were to be stored internally.
The VVP-6 was to have been fitted with six six-blade rotors mounted on six pylons extending from the craft's sides. Each rotor was to have been driven by four turboshaft engines, giving the VVP-6 a total of 36 engines.
This project was abandoned because the Soviet Air Force did not acquire land-based VTOL jets.
