A Wing In Ground-effect vehicle (WIG) is a vehicle that attains level flight near the surface of the Earth, made possible by a cushion of high-pressure air created by the aerodynamic interaction between the wings and the surface known as ground effect
The VVA-14 is not a true WIG vehicle, since the ground effect is only a take off aid. The VVA-14 cruises at an altitude of 10 km where its cruise speed is reached. The first flight of the VVA-14 took place in 1972.
In 1976 a VVA-14 prototype was converted to a VVA-14M1P, the inflatable pontoons were replaced by rigid ones and two additional D-30M turbofans were installed at the nose of the vehicle. These engines blow in the cavity under the wing for PAR take off.
The last model of VVA-14M1P rests in the Air Force Museum of Monino, Moscow, Russia.
