The Miranda engine generates a thrust of 1,000 kilonewtons (230,000 lbf) fueled by liquid oxygen (LOX) and kerosene (RP-1).
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.[2]
Development began in 2022 and in 2024 Firefly reported substantial progress on testing the engine.[3]
