Firefly Alpha is a two-stage orbital expendable launch vehicle developed by the American aerospace company Firefly Aerospace to cover the commercial small satellite launch market. Alpha is intended to provide launch options for both full vehicle and ride share customers.

Alpha's first stage is powered by four Reaver 1 LOX / RP-1 engines, delivering 736.1 kN (165,500 lbf) of thrust. The second stage is powered by one Lightning 1 LOX / RP-1 engine, delivering 70.1 kN (15,800 lbf) of thrust. Lightning 1 was test-run for nearly 5 minutes on March 15, 2018 during a long duration test fire. The engine was fired at Firefly's Test Stand 1 in Briggs, Texas.
