The painting of the operational V-2s was mostly a ragged-edged pattern with several variations, but at the end of the war a plain olive green rocket also appeared.

Shenzhou 8 of the same design. Shenzhou 8 Shenzhou 8 () was an unmanned flight of China's Shenzhou program, launched on October 31, 2011 UTC, or November 1 in China, by a Long March 2F rocket which lifted off from the Jiuquan Satellite Launch Center. The Shenzhou 8 spacecraft was automatically docked with the Tiangong-1 space module (launched on 29 September 2011) on November 3 and again on November 14, 2011. This unmanned docking—China's first—was followed in 2012 with the manned Shenzhou 9 mission, which performed a manned docking (also China's first) with the Tiangong-1 module.
