Progress M

Progress-M (GRAU indices 11F615A55 and 11F615A60), also known as Progress 7K-TGM, is a Russian, previously Soviet spacecraft which is used to resupply space stations. It is a variant of the Progress spacecraft, originally built in the late 1980s as a modernised version of the Progress 7K-TG spacecraft, using new systems developed for the Soyuz-T and Soyuz-TM spacecraft. The 11F61560 variant incorporated further modernisation, with digital flight control systems replacing the earlier analogue ones. The older 11F615A55 spacecraft was phased out in favour of the 11F615A60, with the last launch of the older model in July 2009. [Progress-M. Wikipedia]
