Former factory and design office dedicated to space and rocket propulsion. In 1962 the T-7A booster is made for a probe rocket. It delivered 238 KN for 7,5 seconds.

-From 1966 to 1975 there was the FSW, a retrorocket for satellite recovery. It delivered 41 KN of thrust, and was able to start up after several days in space.

-The FSW was still used in 1988. First it used CTPB fuel passing to the more reliable HTPB.

-Of course, they made all kind of engines for all the necessary missions.

-So the orbit transfer engine, known as perigee, was the one used in the CZ-2E launch rocket.

-This engine used HTPB fuel in grain and coal. It delivered 11,360 KN for 65 seconds.

-By 1990, the "4th Academy" offered the SPAB-54, a solid rocket for the orbital insertion of the Iridium satellites. Etc etc.
