The hot flames of progress
Firefly Aerospace took another step forward in the development of its Miranda engine, which will eventually power the first stage of Northrop Grumman’s Antares 330 and new Medium Launch Vehicle (MLV). For this latest hot fire test, Firefly tested its proprietary tap-off combustion cycle. “This development engine features a truncated nozzle to enable rapid iteration while characterizing engine performance,” the company said on X.
