The U.S. Navy’s newly established Direct Reporting Portfolio Manager for Robotic and Autonomous Systems (DRPM RAS) has issued an official solicitation for the Tactical Resupply Unmanned Aircraft System (TRUAS) Increment II program.
Sponsored under the Air Warfare Program Management Office at NAS Patuxent River, the Navy is hosting an Industry Demonstration in Huntsville, Alabama, scheduled from January 25 to February 5, 2027. Applications close on November 30, 2026, with selected participants competing for potential Other Transaction Authority (OTA) prototype agreements under 10 U.S.C. § 4022. TRUAS Increment II seeks a second-generation autonomous aerial resupply platform engineered to execute long-range, tactical “last-mile” logistics for distributed U.S. Marine Corps formations in contested Expeditionary Advanced Base Operations (EABO) environments.

TIMES OF DEFENCE ASSESSMENT
The transition from the battery-electric TRV-150C (Increment I) to the heavy-fuel/hybrid-powered Increment II reflects real-world operational lessons learned from Marines conducting distributed logistics in island-hopping scenarios.
From an engineering and tactical doctrine standpoint, Increment II resolves key operational bottlenecks:
1. **Shifting from Battery-Electric to Heavy Fuel**: While the TRV-150C provided initial tactical resupply capabilities, battery charging in forward-deployed austere locations relies on heavy generators or fixed power infrastructure. Requiring heavy-fuel (JP-8/diesel) engines allows cargo drones to burn the exact same fuel used by Marine Joint Light Tactical Vehicles (JLTVs) and tactical generators, eliminating battery-charging delays and extending operational range nearly ninefold (from ~9 miles out to 40 nautical miles).
2. **Empowering Distributed Operations (EABO)**: Small Marine Corps units deployed across isolated islands or riverine environments require persistent resupply without risking crewed rotary-wing platforms (e.g., MV-22B, CH-53K). Carrying 100 to 150 lbs of critical supplies—such as medical kits, 81mm mortar rounds, small arms ammunition, or battery packs—over an 80-nautical-mile round trip provides small-unit commanders with an organic, low-signature logistics line.
3. **Advanced Software Automation & Multi-Drone Control**: Requiring a single operator to manage four drones via voice-directed commands shifts the cognitive load away from manual piloting toward mission oversight. Fusing GPS-denied navigation, natural language interaction, and automated airspace authorization via the Multifunction Air Operations Center aligns uncrewed aerial logistics with modern, high-density battlespace requirements.
