Deficiencies revealed in the course of the V-2's development prompted the Mil OKB designers to start work on ways of modernising it right after construction of the first prototypes was completed. As early as 1964, full-size mock-ups were ready in the the assembly shop of the Plant No. 329, representing two derivatives of the V-2 designed to carry 10 passengers. One of them, designated Mi-3 (second use of designation), featured an enlarged-section fuselage with aft clamshell rear doors and external fuel tanks in sponsons looking like stub wings which served as attachment points for the main undercarriage units. The other one, designated V-20, featured a lengthened fuselage (a "plug" was inserted aft of the cockpit). However, calculations showed that with GTD-350 engines these machines would be underpowered. Therefore the Mil OKB began studying projects providing for the replacement of the GTD-350 by more advanced gas turbines, such as the Izotov GTD-550, Glushenkov GTD-10, Glushenkov GTD-3, Continental T65 and Turboméca Astazou XIV.

Military customers expressed interest in the project of the V-20 with the GTD-10A engine delivering 1,250 shp. This evolved into the project of the Mi-22 helicopter (the first to bear this designation) in 1965; possessing an all-up weight of 4,300 kg (9,480 lb), it was intended to transport a mechanised infantry squad. It differed from the Mi-2 in having an aerodynamically cleaner fuselage, a four-blade main rotor, a skid undercarriage and wide sliding side doors. The work on the Mi-22 reached the stage of mock-up studies and was halted in the early 1970s in connection with the emergence of the Mi-24 which, at that time, was envisaged as being capable also of transporting infantry troops.

Mi-22 Hook-C

The 'Hook-C' is a development of the Mi-6VKP 'Hook-B' airborne command post. The Mi-6 is a big, powerful transport helicopter. Getting this large vehicle in the air was no easy task; the Mi-6 has an enormous gearbox, heavier than its engines, and often uses short wings to unload the rotor in cruise. It was not only for a long time the largest helicopter, it was also the fastest.

The Mi-6VKP (vozdooshnyy ko-mahndnyy poonkt) was an airborne command post (ABCP). Air control Mi-6VKP developed at the plant number 535, based on a series MI-6. To that end, the factory has been specially created to guide the Division equipment (ALO), which was headed by Major General J. M. Melnikov. Design began in late 1972. Alteration of mass-produced Mi-6, received from the Rostov Helicopter Plant, was done at the plant number 535. This variant created by the military at the end of the 1960s was intended for combat control of units at the army level (ground forces armies or air armies). The helicopter's cargo hold was provided with a communication equipment suite and a comfortable compartment for headquarters officers. However, the ABCP could only function after landing and deploying its equipment on the ground. Construction of the Mi-6VKP similar to the base. The cargo cabin located communication center (the developer NPP flight) and lounge for staff officers. At the tail beam installed additional antenna. The helicopter was intended to combat and control the army general or air. The last Mi-6VKP operated until 1996.

The Mil OKB started the development of a modification which could perform the same functions without landing. It received the designation Mi-6AYa (Mi-6VzPU), the latter suffix denoting vozdooshnyy poonkt oopravleniya - airborne control post. This version entered service in 1975 under the designation Mi-22 (theme "ruby"). Construction of the Mi-22 helicopter similar to the base. In the cargo cabin equipped with jobs staff officers, identified additional means of communication. Under the fuselage installed additional antenna.
