About
About Firefly
Firefly is Parallel Flight Technologies’ hybrid heavy-lift aircraft, combining liquid-fuel replenishment with an electric propulsion architecture and power for mission equipment. It provides up to 2 kW of continuous onboard power for third-party payloads, allowing the aircraft to support powered sensors or other equipment as well as carrying a passive load.
The flight-control system supports autonomous missions, with the payload and operating arrangement selected for logistics, surveillance or industrial work. Parallel Flight specifies a maximum load of 100 pounds and up to 74 miles of range at full payload, with a stated endurance of 1.4 hours. Rapid refuelling supports repeated sorties in locations where charging infrastructure would constrain the turnaround process.

Timeline
- ONR awards Parallel Flight USD 3.74M maritime Firefly UAS contract
2025-09-09 - Contract Award - The work adapts Firefly for naval-vessel operations and maritime environmental requirements. The award is separate from Parallel Flight's earlier NSIC funding and Alpha Drones order.
Source - Firefly demonstrates maritime countermeasure capabilities at TCE 24.2
2024-09-11 - Demonstration - The demonstration involved littoral maritime operations with partner Areté and Office of Naval Research context. The test showcased littoral maritime countermeasure capabilities rather than a fielded customer deployment. The demonstration validates The company's technology in maritime autonomy, underwater robotics or marine inspection workflows.
Source - Alpha Drones orders five Parallel Flight Firefly UAVs
2024-03-07 - Commercial Order - The order covered initial Firefly units expected to ship near the end of 2024. It is a commercial order because the primary fact is booked drone units.
Source - Parallel Flight wins USD 1M NSIC award for heavy-lift UAS
2023-11-29 - Award - The award supported advancement and expansion of the company’s Firefly aircraft. Parallel Flight develops autonomous heavy-lift drones for missions such as logistics, wildfire response and public safety.
