Launches edit

It made its maiden flight on 25 April 2008, at 15:35 UTC. The payload for the first launch was the Tianlian I-01 data relay communications satellite. The second carried the Compass-G2 navigation satellite and was conducted on 14 April 2009. The third launch was made on 16 January 2010, with the Compass-G1 satellite. The fourth carrying the Compass-G3 navigation satellite was launched on 2 June 2010. On 1 October 2010, it successfully launched China's second lunar probe, Chang'e 2.

An enhanced version, named Long March 3C/E, debuted during the launch of Chang'e 5-T1 on 23 October 2014.[7] On 30 March 2015, the Yuanzheng upper stage was used on top of a Long March 3C launch vehicle for the first time.[8]
