Miranda is a liquid-fueled rocket engine currently being developed by Firefly Aerospace. The engine is designed to power both Firefly's MLV (Medium Launch Vehicle) and the Antares 330 from Northrop Grumman.[3]
Its development was necessitated by Russia's invasion of Ukraine, the RD-181 engine previously used on the Antares was built in Russia and subject to sanctions.[4]
Development began in 2022 and in 2024 Firefly reported substantial progress on testing the engine.[5]
