The Antonov KT was developed in 1940 by a designer of weight-carrying gliders, Oleg Konstantinovich Antonov. The aim was to test the viability of supplying partisan forces behind enemy lines with light tanks. The unit was towed by a heavy bomber such as the Petlyakov Pe-8. A model "T-60" light tank provided the 'fuselage' of the unit, the unlocked tracks were the 'landing gear'. The flying surfaces were to be disposed of immediately after landing.
