Harbinger has launched Praesidia, an unmanned hybrid-electric platform for defense customers, military applications and defense prime contractors, built on the same clean-sheet medium-duty plug-in hybrid chassis used in its commercial vehicles. The announcement comes alongside a strategic investment from In-Q-Tel and highlights how Harbinger is positioning its commercial architecture for defense use.
A series hybrid platform built for power export
Harbinger Praesidia runs on what industry coverage describes as a series hybrid drivetrain. An electric motor handles propulsion while a compact gasoline engine and generator recharge the battery pack or supply power directly to external systems. Harbinger says the platform delivers over 500 miles of total hybrid range and approximately 105 miles on battery alone in its standard configuration.
Harbinger says the platform can export up to 350 kilowatts, supported by 48 kilowatts of continuous engine output and a 15-kilowatt onboard inverter for split-phase AC. Charging takes about four hours for a 10% to 80% AC charge. A 10% to 80% DC fast charge takes roughly one hour.
A commercial foundation with defense-specific systems layered on
Harbinger built Praesidia on its existing medium-duty chassis rather than developing a bespoke military vehicle from scratch. The platform is offered across the same three wheelbases used commercially, 158 inches, 178 inches and 208 inches, with gross vehicle weight ratings spanning 16,000 to 26,000 pounds and payload capacity up to 18,000 pounds.
That shared foundation carries forward existing engineering, including drive-by-wire systems and an operating tolerance from -30°C to 55°C at altitudes up to 12,000 feet. Harbinger layers defense-specific systems onto that base platform, including full teleoperation through a proprietary API, redundancy across steering, braking and acceleration controls, a six-camera 360-degree situational awareness system, dual-network radio and satellite communications, and a stealth mode that disables exterior lights, acoustic alerting and the onboard generator. American Rheinmetall is contributing further vehicle integration and mission systems work under a separate partnership, indicating the commercial chassis serves as a starting foundation rather than a finished defense product.
Investment and industry signal
In-Q-Tel, the not-for-profit strategic investor that supports the U.S. national security community, joined Harbinger as a strategic investor alongside the platform launch. Sara Jones, Principal at IQT, said Harbinger’s vertically integrated platform brings together power generation, energy storage and mobility in a way that extends to emerging government and national security needs. Industry reporting indicates neither company disclosed the investment value.
Harbinger has also formed a partnership with American Rheinmetall, announced in May 2026, to jointly pursue uncrewed ground vehicle programs. Under that agreement, American Rheinmetall contributes vehicle integration and modular mission architecture while Harbinger supplies the autonomy-ready hybrid platform itself. Trade press covering the broader defense sector has noted other established automakers exploring similar government and defense crossover, suggesting Harbinger’s move reflects a wider industry pattern rather than an isolated strategy.
What comes next
Harbinger has not disclosed contract values, specific government customers or production timelines tied to the Praesidia launch. The company’s dual-use strategy, building defense and commercial vehicles from a shared engineering and manufacturing base, suggests further crossover announcements are likely as the Rheinmetall partnership matures and additional mission configurations come online.
