The Soyuz-FG launch vehicle is an improved version of the Soyuz-U, from the R-7 family of rockets, designed and constructed by TsSKB-Progress in Samara. It made its maiden flight on May 20, 2001, carrying a Progress M1-6 cargo spacecraft to the International Space Station (ISS).

Since October 30, 2002 the Soyuz-FG has been the only vehicle used by the Russian Federal Space Agency to launch Soyuz-TMA and Soyuz-MS manned spacecraft to the ISS. All launches have been successful thus far.[2]

Another version of the Soyuz-FG is the Soyuz-FG/Fregat with Fregat as its 3rd stage, developed and produced by Lavochkin Association in Khimki. A European-Russian company Starsem owns all rights to launches using this version. As of December 2014 there have been 10 launches of Soyuz-FG/Fregat with commercial payloads.[3] Its maiden flight occurred on June 2, 2003.

The analog control system of this spacecraft significantly limits its capabilities, and it will eventually be replaced by the Soyuz-2 launch vehicle.

The Soyuz-FG is launched from the Baikonur Cosmodrome in Kazakhstan, using launch site LC-1/5 for Soyuz-FG and LC-31/6 for Soyuz-FG/Fregat.
