This kerosene liquid oxygen series of boosters in all cases are to do the building block technology demonstration path finding hard development work for the benefit of the Long March-5 medium heavy lift booster series.

LM-2F/G Unmanned SLV

The LM-2F/G [ "G" stands for Gai or "change" of fuel from N2OH/UDMH to LOX/kerosene] launch vehicle will be used strictly for carrying unmanned and man tended space laboratory with no emergency launch escape tower and a larger diameter payload shroud. This will give the booster a payload capacity on the order of between 11.2 and 13 metric tones payload capacity to low earth orbit with a launch mass on or about 579 metric tons. Carrying the launch escape tower renders a serious payload capacity penalty for boosters using it for manned flight. This booster series has had it entire inertial guidance and flight avionics control systems totally redesigned for greater accuracy and safety. The two stage core will remain the same 3.35 meters in diameter utilizing a two YF-100 engine cluster in its first stage and a single altitude version of the YF-100 kerosene liquid oxygen engine on the second stage. The four strap-on boosters 2.25 meters in diameter will utilize a single 120 tons thrust YF-100 kerosene liquid oxygen propellants engine. That gives it a total liftoff thrust on the order of 720 metric tons. The overall length is planned to be 52 meters. Its first flight test is expected in the 2009-2010 time period.
