DF-5
The Chinese flight tested a vehicle with ICBM characteristics to a reduced range in September 1971. The earliest possible IOC for an ICBM based on this vehicle was projected by US intelligence in 1972 as being late 1974, but more likely a year or two later.
Development problems evidently precluded initial deployment of the DF-5 as an operational ICBM, but the space-launch version referred to by the Chinese as the FB-1 (Fengbao-Tempest) - was used as the booster for a series of five satellite shots that began in July 1975 and concluded in December 1976. The rocket uses four first-stage gimballed engines and one second-stage engine, all of which burn N2O4/UDMH. The Dongfeng-5 possessed the capability to hit targets in the western Soviet Union and the United States.
