Blue Origin BE-7
Blue Origin BE-7 dual-expander LOX/LH2 liquid rocket engine variant for lunar-landing propulsion. Blue Origin testing material identifies a 10,000 lbf thrust class and throttling to 2,000 lbf; NASA identifies BE-7 cryogenic engines for the Blue Origin lunar-lander descent element. The engine remains in development, and no family or vehicle-family relationship is asserted here.
