Design and development
editThe SAM-2 was an extensive modification of the Grigorovich MU-2, MU standing for morskoi uchyebnyi or marine trainer. It retained the pusher configuration biplane layout, its open, side-by-side cockpit and many components. New features were an improved hull underside, or planing bottom, smaller wings and a much lighter structure.[1]
Operational history
editIt was completed in February 1931 and was officially tested in the spring. These led to its abandonment in favour of the parasol wing Shavrov Sh-2 amphibian which was built in large numbers, some active as late as 1964.[1][2]
