The BE-3 is a family of liquid hydrogen/liquid oxygen (LH2/LOX) cryogenic engines, crucial for Blue Origin's suborbital and orbital ambitions. It features two main variants:

• BE-3PM: A pump-fed engine with a combustion tap-off cycle, producing 490 kN (110,000 lbf) of thrust. It powers the Propulsive Module of the New Shepard vehicle and can be throttled down to 110 kN for controlled vertical landings.
• BE-3U: An open expander cycle variant, generating 710 kN (160,000 lbf) of thrust. Two BE-3U engines are designed to power the second stage of the New Glenn heavy-lift launch vehicle.

💪 BE-4: The Powerhouse

The BE-4 is a liquid oxygen/liquified natural gas (LOX/LNG) rocket engine, a significant development for both Blue Origin and its partners. It is capable of producing a formidable 2,400 kN (550,000 lbf) of thrust. Development for the BE-4 began in 2011, leading to a crucial agreement in late 2014 with United Launch Alliance (ULA). Under this agreement, the BE-4 was selected to power ULA's Vulcan Centaur rockets, replacing the Russian-made RD-180 engines. Two BE-4 engines provide the main power for the Vulcan Centaur's first stage. The first BE-4 engines were delivered to ULA in October 2022 and successfully test-fired in June 2023, with the Vulcan Centaur's maiden flight in January 2024 utilizing these engines. The BE-4 also powers the first stage of Blue Origin's own New Glenn rocket.^{[42][43][44][45][46][47]}

🌕 BE-7: Lunar Precision

The BE-7 engine is a liquid oxygen/liquid hydrogen (LOX/LH2) dual expander cycle engine specifically designed for lunar applications. It is currently under development and is intended for use on the Blue Moon lunar lander. The engine produces 44 kN (10,000 lbf) of thrust, optimized for the precise maneuvers required for soft lunar landings. Its first ignition tests were conducted in June 2019, with thrust chamber assembly testing continuing through 2023, demonstrating Blue Origin's commitment to developing specialized propulsion for deep space missions.^[48][49]

🛡️ Pusher Escape Motor

For the safety of its suborbital crew, Blue Origin developed a pusher launch escape system for the New Shepard crew capsule. This system is a collaborative effort with Aerojet Rocketdyne, which provides the Crew Capsule Escape Solid Rocket Motor (CCE SRM). Blue Origin designs and manufactures the thrust vector control system, which is critical for steering the capsule during an abort scenario. This innovative system enhances safety by being reusable and avoids the jettison event associated with traditional "tractor" launch escape systems, reflecting a focus on both safety and cost-effectiveness.^[50][51]
