As early as 1968, when N.I.Kamov was still alive, the OKB joined the competition of design studies for an Army assault/transport helicopter. The Kamov contender was a derivative of the Ka-25 designated Ka-25F featuring a redesigned fuselage and skid undercarriage. The armament comprised a 23-mm GSh-23 cannon with 400 rounds in a chin turret, six UB-16-57 rocket pods with 57-mm unguided rockets, six "Falanga" (Solifuge) anti-tank guided missiles, and bombs. The Ka-25F project received a positive appraisal from the Air Force's research institutes but lost out to the competing Mi-24 helicopter.
