The success of the Yak-24 helicopter has not gone unnoticed. And in the design office reflect on the creation of the project has a larger helicopter, performed on the same longitudinal scheme. Thus was born the project of heavy military transport helicopter Yak-60, which is on duty could compete with a number of military transport aircraft. This machine is a further development of the largely successful Yak-24. The further development of the Yak-24 type of helicopter was supposed to be the Yak-60, with a takeoff weight of about 100 tons and a payload of 42 tons, able to transport tanks. But, unfortunately, the Yak-60 remained a project. Given the experience of creation and operation of the helicopter Yak-24, at the Leningrad branch of OKB-115, MAP factory #272 in Leningrad, under the leadership of Igor A. Ehrlich, according to the February 1958 Council of Ministers decree, elaborated upon the draft of the new heavy helicopters with the longitudinal scheme - the Yak-60. Rotors were borrowed from the Mi-6, each of which rotates with two engines D-25VF. The helicopter planned to use four gas turbine engines D-25VF, capacity 6497 liters. Planned load should be more than 40 tons. Dimensions of the Yakovlev giants were the following: the length of 44.6 meters, width of 8.6 meters and a height of 11.6 meters. Carrying capacity of the Yak-60 was 42 tonnes and a maximum takeoff weight - 100 tons.
Work on the design of the Yak-60 was engaged in the Leningrad branch of OKB-115 factory #272 MAP directly under the chief designer Igor Alexandrovich Ehrlich. The draft of the new heavy helicopter began to develop on the basis of the USSR Council of Ministers Resolution of February 1958. These dimensions and load capacity of 40 tons before the helicopter opened great opportunities. The purpose of the helicopter giant, which is superior to "Flying car" Yak-24, had airlift: tanks, self-propelled guns, armored personnel carriers, ballistic missiles, ground-based radar, bridge girders, pontoon units, derricks, masts power, river ships, ammunition and other weapons, as well as a variety of oversized cargo for household purposes. The purpose of the giant helicopter was transport by air of tanks, armored personnel carriers, self-propelled units, ground radar, ballistic missiles, pontoon units, bridge girders, ammunition and other weapons, masts power, oil rigs, river boats and other large-scale national economic goods. In addition to the spacious cargo compartment, cargo can be transported on external sling. At the same time it could carry up to 228 troops in full gear and 176 wounded and 8 medical workers. By helicopter work did not come on the technical proposal, due to the failure of OKB-115 from the helicopter theme and closing its Leningrad branch of a subsequent reorientation of the plant number 272 . Such a giant helicopter was established in Mil, which became the world's largest helicopter, the V-12.
