Long March 6

The Long March 6A has a fully fueled mass of 530,000 kilograms.

The Long March 6A can deliver 8,000 kilograms to low Earth orbit.

The Long March 6A first and second stages have a diameter of 3.35 meters, and its solid-fuel boosters have a diameter of 2 meters.

The Long March 6A can deliver 4,500 kilograms to a 700-kilometer sun-synchronous orbit.

The Long March 6A has four solid rocket boosters that each produce 124 tons of thrust.

The Long March 6A was developed by the Shanghai Academy of Spaceflight Technology.

The July 4 launch was the 25th mission of the Long March 6A.

The July 4 Long March 6A mission carried a group of Qianfan connectivity satellites into a near-polar orbit.

The Long March 6A generates a total thrust of 736 tons from its first stage and boosters.

The Long March 6A second stage uses a single YF-115 engine that produces 18 tons of thrust.

The Long March 6A is the first new-generation Chinese launch vehicle to use a combination of solid and liquid propellants.

The Long March 6A uses a two-and-a-half-stage design.

GuoWang satellites launched on the Long March 5B and Long March 6A use a larger platform that is about 30% bigger and weighs up to 1,000 kilograms.

Long March 6A Y25 launched SpaceSail Group-11 from Taiyuan at 11:39 UTC on June 4, 2026.

Qianfan deployments are expected to continue in early June with Long March 8 series and Long March 6A flights.

Most of the lingering second-stages are Long March 6A upper stages.

Qianfan and GuoWang have also used the Long March 6A for constellation deployment launches.

Long March 6A Y23 launched from Taiyuan Satellite Launch Center on 12 May.
