The Miranda Engine is an under development rocket engine by Firefly Aerospace and to be used in Firefly Aerospace's own MLV (medium launch vehicle) and the Antares 300 series.[1]
Design[edit]
The engine utilizes a mixture of liquid oxygen and kerosene generating 230,000 pounds-force of thrust. Seven of the engines will power the first stage of the Antares 300 series as well as the first stage of Firefly Aerospace's MLV.[2]
Development[edit]
The need for development came as a result of Russia's invasion of Ukraine, as the engine's that powered the 200 series Antares were supplied by a Ukrainian company.[3] Development began in 2022 and in 2024 Firefly reported substantial progress on testing the engine.[4]
