Satellite & Space Propulsion Systems
AMPAC-ISP’s LEROS™ 1 family of flight-proven, bipropellant, dual mode apogee engines have demonstrated performance improvements for three design generations. These engines have provided a cost-effective solution to challenging satellite apogee and interplanetary missions. The LEROS™ 2B engine adds monomethylhydrazine (MMH) apogee capability to the LEROS™ family, offering high performance in a coated columbium engine – at an excellent value.

The Most Reliable Upper Stage Engine
The Agena 2000 engine is the latest and most sophisticated version of our Agena engine line, which has achieved space industry acclaim as the most reliable upper stage rocket engine ever developed in the United States. It uses pump-fed nitrogen tetroxide (NTO) and MMH to produce 15,000 lbf of thrust at a specific impulse of 336 seconds.
