The Kosmos-3M (Russian: Космос-3М meaning "Cosmos", GRAU index 11K65M) was a Russian space launch vehicle, member of the Kosmos rocket family. It was a liquid-fueled two-stage launch vehicle, first launched in 1967 and with over 420 successful launches to its name.
The Kosmos-3M used UDMH fuel and AK27I oxidizer (red fuming nitric acid) to lift roughly 1,400 kg (3,100 lb) of payload into orbit. It differed from the earlier Kosmos-3 in its finer control of the second-stage burn, allowing operators to tune the thrust and even channel it through nozzles that helped orient the rocket for the launching of multiple satellites at one time.
PO Polyot manufactured these launch vehicles in the Russian city of Omsk for decades. It was originally scheduled to be retired from service in 2011;[2] however, in April 2010 the Commander of the Russian Space Forces confirmed that it would be retired by the end of 2010.[3] One further launch, with Kanopus-ST, was planned; however, this was cancelled in late 2012 as the launch vehicle had exceeded its design life while in storage ahead of the launch.
