BE-3PM

BE-3PM is Blue Origin’s reusable liquid-oxygen/liquid-hydrogen engine for New Shepard’s propulsion module. Its tap-off cycle and single combustion chamber support deep throttling and restart for vertical landing. Blue Origin lists up to 110,000 lbf (490 kN) thrust and throttling down to 20,000 lbf (90 kN). On 23 November 2015, it powered New Shepard above the Karman line and reignited for a successful soft landing. That flight-to-space-and-recovery milestone is distinct from the earlier BE-3-powered New Shepard developmental flight of 29 April 2015. The vacuum-optimized BE-3U is a separate family member.

    Note
    Current engine page identifies BE-3PM propellants and deep-throttle capability. Its 23 November 2015 milestone is the flight above the Karman line and successful booster landing. Blue Origin separately documents a BE-3-powered New Shepard developmental flight on 29 April 2015, so the November milestone does not establish the first flight of the wider BE-3 design.
