The Firefly-class is a series of Multipurpose, Mid-Bulk Transport boats designed by Allied Spacecraft Corporation. The hulls and engines are constructed at ASC's shipyard at New Burbank, Osiris, with final outfitting being outsourced to a dozen smaller companies, including the newly formed Firefly Ship Works on Hera.
All Fireflys feature a large rear engine module, wing-mounted engines capable of vertical takeoff and landing (VTOL), a centralized cargo section, and raised forward section holding the crew quarters and bridge.
