Antonov A-40

Instead of loading light tanks onto gliders, as other nations had done, Soviet airborne forces had strapped T-27 tankettes underneath heavy bombers and landed them on airfields.

During the 1940 occupation of Bessarabia, light tanks may have been dropped from a few meters up by TB-3 bombers, which, as long as the gearbox was in neutral, would allow them to roll to a stop.

Instead of building a glider, he added a detachable cradle to a T-60 light tank bearing large wood and fabric biplane wings and a twin tail.

The tank was lightened for air use by removing its armament, ammunition and headlights, and leaving a very limited amount of fuel.

Even with these modifications, the TB-3 bomber had to ditch the glider during its only flight, on September 2, 1942, to avoid crashing, due to the T-60's extreme drag (although the tank reportedly glided smoothly).
