Miranda is a liquid-fueled rocket engine currently being developed by Firefly Aerospace to power the company’s MLV (Medium Launch Vehicle). It will also be used on the Antares 330 rocket developed by Northrop Grumman.[3]
The Antares previously used a Ukrainian-built first stage with the Russian-built RD-181 engine and production ceased after the Russian invasion of Ukraine.[4] Firefly will also assemble the entire first stage for the Antares 330.[5]
Development began in 2022 and in 2024 Firefly reported substantial progress on testing the engine, with 20 test fires completed. As of June 2024, the Miranda engine had entered production.[5]
Firefly said that it has designed the Miranda from its inception for reusability. The company plans to restart the engine multiple times as the rocket performs a return-to-launch-site maneuver for a propulsive landing.[5]
