Yakovlev Yak-60 (known as Yak-32 in some sources)[1] is the possible designation for an experimental Yakovlev tandem-rotor heavy-lift helicopter design of the late 1960s.
This design never progressed beyond the model stage.
It featured two Mil Mi-6 rotors in tandem, each driven by a pair of 6,500 hp (4,800 kW) Soloviev D-25VF engines, potentially giving it four times the payload capacity of the Boeing CH-47 Chinook.
Compared to the radical Mi-12, the Yak-60 design was far more conventional, though two Mi-12s were produced and no Yak-60s.
[2] It has been suggested that the designation Yak-60 was based on an extant study model which had the number "60" painted prominently on its side.
