Jiangnan Shipyard
Yuan Wang 22 is also a cargo ship designed specially to transport rockets such as Long March 5, and it is also built by Jiangnan Shipyard, the same builder of earlier Yuan Wang 21. Yuan Wang 22 might be a sister ship of Yuan Wang 21, but this cannot be confirmed yet, because detailed information / specification of Yuan Wang 22 has not been released by official Chinese governmental sources yet (as of 2014). Yuan Wang 22 was launched on January 24, 2013.
