The Long March 2D (Chinese: 长征二号丁火箭), also known as the Chang Zheng 2D, CZ-2D and LM-2D, is a Chinese orbital carrier rocket. It is a 2-stage carrier rocket mainly used for launching LEO and SSO satellites. It is mainly launched from areas 2B and 4 at the Jiuquan Satellite Launch Center. The Long March 2D made its maiden flight on 9 August 1992. It is most commonly used to launch FSW-2 and 3 reconnaissance satellites. The general designer of Long March 2D is Mr. Ma Jia (马佳). Unlike other members of the Long March 2 rocket family, Long March 2D is a two-stage version of Long March 4 launch vehicle.
