CZ-11H (Chang Zheng-11H)

CZ-11H (Jilin-1 Gaofen-03A) [Xinhua]

The CZ-11 (Chang Zheng-11), also known as LM-11 (Long March-11), is a small solid-fueled quick-reaction launch vehicle.

The CZ-11 is developed by the China Academy of Launch Vehicle Technology (CALT) with the goal to provide a quick-reaction launch vehicle, which is easy to operate, cost-efficient to launch, can remain in storage for long period and reliably launch on short notice. Reportedly, the payload is about 1000 kg.

It consists of four solid-fueled stages. It uses the largest solid rocket motor developed in China so far as first stage. With a diameter of 2 m, it is likely based on the DF-31 missile. The vehicle is cold launched from a launch tube mounted on a road mobile vehicle.

Both a 1.6 m and a 2.0 m diameter payload fairing are available for the CZ-11 launch vehicle.

The maiden flight took place in September 2015 from Jiuquan.

In June 2019, a version called CZ-11H was launched off-shore from a barge at the Yellow Sea. How the barge launched version differs from the standard version, is not known. For later launches, the dedicated DeBo-3 launch ship is used.

An improved version, CZ-11A, is planned to use a new 2.4 m solid motor as stage 1.
