The Russian Military's Largest Helicopter

Awesome footage of a giant helicopter that was started at the Mil OKB in 1959, receiving official sanction in 1961 by the GKAT who instructed Mil to develop a helicopter capable of lifting 20 to 25 t (44,000 to 55,000 lb). The GKAT directive was followed by a more detailed specification for the V-12 with hold dimensions similar to the Antonov An-22, intending to lift major items of combat equipment as well as 8K67, 8K75 and 8K82 inter-continental ballistic missiles (ICBM).
