The A.M. Isayev Chemical Engineering Design Bureau (Russian: Конструкторское бюро химического машиностроения имени A.M. Исаева), also known as KB KhimMash or just KBKhM, is a Russian rocket engine design and manufacturing company. It is located in the city of Korolyov. It started as the OKB-2 division of the NII-88 research institute, where A.Isaev directed the development of liquid rocket engines for ballistic missilesubmarines.
KDU-414: Pressure-fed liquid rocket engine burning UDMH and RFNA. Used on early soviet deep space probes.
KTDU-35: Liquid rocket engine burning UDMH and AK27I in the gas generator cycle. Used on first generation Soyuz, and Progress.
KTDU-425: Pump-fed liquid rocket engine. Used on the 4MV bus employed by unmanned Mars and Venus probes.
KTDU-426: Spacecraft version of the S5.79. Used on the Soyuz-T.
