LM-4B/4C
Long March 4B/4C Launch Vehicle (LM-4B/4C) is three-stage storable liquid propellant launch vehicles with 47m in length and 3.35m in diameter. It is mainly used for SSO, LEO and highly elliptic orbit satellite missions. LM-4B was successfully launched for the first time on May 10th, 1999. LM-4C was successfully launched for the first time on April 27th, 2006.

LM-4B/4C Configuration
Besides single payload missions, LM-4B/4C can also perform multiple-satellite missions and piggyback missions. LM-4B can deliver a 2200kg payload into 700km SSO. LM-4C can deliver a 2800kg payload into 700km SSO.
The standard payload adapter interfaces that LM-4B/4C adopts are Φ660, Φ937, Φ1194, Φ1664 and Φ2000, and LM-4B/4C can also provide Φ300 and SPOD interfaces for piggyback missions.
