Experimental ekranoplan (WIG vehicle) SM-2 was built at the same time as SM-1 and had almost identical construction. It was damaged in a hangar fire. Trials of the SM-1 revealed shortcomings of the tandem configuration, and SM-2 was restored as a SM-2P.

New aircraft had single rectangular (priamougolnoe in Russian, so the P in designation) wing with aspect ratio 1.2 and a high T-tail. Single engine of the SM-2P was installed in the extreme tail, with air intake at the tail fin root.

Handling was better than of the SM-1, but takeoff run was still un-practical. For the lift, aircraft relied entirely on the dynamic air cushion . To achieving sufficient lift without power augmentation, SM-2P had to accelerate to
