China successfully launched 18 communications satellites on May 12, 2026, as part of the SpaceSail Polar Group 09 mission. Operated by Shanghai Spacesail Technologies with backing from Shanghai's municipal government, the satellites are equipped with Ku, Q, and V band payloads designed to support the G60 constellation. This deployment represents a significant milestone in establishing a megaconstellation aimed at global broadband coverage and communications services.

The Long March 6A rocket, operated by China Aerospace Science and Technology Corporation, lifted off from the Taiyuan Satellite Launch Center at 20:59 Japan Standard Time. The Long March 6A is a solid-fueled launch vehicle designed for medium-lift missions, making it well-suited for deploying multiple satellites to low Earth orbit in a single flight.

The successful launch advances SpaceSail's ambitious expansion plans. The initial constellation is expected to comprise 1,296 satellites by 2027, with long-term projections to eventually expand the network to 12,000 satellites. This development reflects China's growing investment in commercial space infrastructure and positions Shanghai Spacesail Technologies as a major competitor in the emerging megaconstellation market.
