Space Transportation Company Achieves Critical Milestone in Engine Development

Firefly Aerospace has completed the first hot fire test for its Miranda engine, a critical milestone in the development of its propulsion system. The test was conducted at Firefly’s rocket test and production site in Texas and validates the design of the engine’s startup sequence and transient conditions. As part of its efforts to develop the Antares 330 and Medium Launch Vehicle (MLV), Firefly is also designing, manufacturing, and testing the first stage structures for Antares 330 as well as the structures and fluids systems for both MLV stages. The company has doubled the size of its facilities at its rocket test and production site in Briggs, Texas, and is utilizing new automated manufacturing equipment to support vehicle production.
