China carried out its first-ever launch of a satellite from a sea-based mobile platform on 5 June. The event took place in the Yellow Sea using a Long March 11 rocket that carried seven satellites into orbit, some of which are for commercial use, while the others are for scientific data-gathering and communications development, according to China’s state-owned Xinhua news agency.

All of China’s previous satellite launches had been conducted from one of the four satellite launch centres, located at latitudes between 19–49° north.
The latitude of the launch position in the Yellow Sea is reported to have been 34.9° north and 121.19° east, so it is likely to have been a demonstration of the viability of the sea-based platform. For the next launch, the platform will probably be positioned much further south to optimise the launch position in relation to the intended orbit of the satellites.
The first flight of a Long March 11 rocket took place in September 2015, with the most recent launch being the seventh overall. Although this version has a smaller payload capacity than other variants of Long March rockets, the flexibility the sea-based platform offers in launch position will minimise the fuel required on board the satellites to achieve their orbit, thus reducing the proportion of the payload allocated to fuel.
