WASHINGTON, D.C., — U.S.-Norwegian defence company Heaviside Industries has unveiled its TYR loitering munition at the Association of the United States Army (AUSA) Annual Meeting and Exposition in Washington, D.C. The lightweight, fixed-wing system weighs just over five pounds (2.3 kilograms) and is designed to strike targets at ranges exceeding 25 miles (40 kilometres).
According to the company, TYR can reach speeds exceeding 150 mph (241 km/h) and remain airborne for more than 60 minutes. The complete system weighs approximately 15 pounds (6.8 kilograms), making it suitable for transport by individual soldiers. Its detachable wings help with backpack transport, while its low acoustic and visual signature is intended to reduce detection.
GPS-Denied Operations and Mission Capabilities
TYR is designed to operate in GPS-denied environments and contested communications conditions. It uses proprietary dual-band radios and computer vision for navigation and targeting. The system also features electro-optical and thermal cameras to support target identification.
According to Heaviside, the munition can search designated areas for recognisable targets and request operator confirmation before an attack. The final engagement decision remains with a human operator. If communication is lost, the system has several programmed options: abort the attack, continue the mission, land in a designated safe area or destroy itself.
The company says TYR can support ground and base defence, counter-drone missions and integration with larger unmanned systems. It is designed for precision strikes against armoured vehicles, fortified structures and other targets.
Four Warhead Options from Nammo
TYR uses four interchangeable warhead options supplied by Norwegian defence company Nammo: a shaped-charge anti-tank warhead, an anti-structure munition, an explosively formed penetrator (EFP) and an anti-personnel fragmentation warhead.
The anti-tank variant is intended to engage armoured vehicles, including main battle tanks. The different warhead options allow the system to be configured for different mission requirements.
Heaviside and Nammo announced a strategic partnership in August 2026 to develop multi-domain precision munitions, with TYR serving as the first platform under the collaboration.
Testing, Contracts and Production
Heaviside CEO Phillip Walker said TYR combines size, weight and performance to engage armoured and fortified targets while allowing troops to maintain greater standoff distance from threats.
The company said TYR has completed live-fire testing and is under contract with U.S. Department of Defense customers. Specific order quantities and delivery schedules have not been disclosed.
Heaviside also announced a $60 million Series B funding round in August 2026, valuing the company at $600 million. The funding is intended to support production capacity and expansion of its U.S. operations. The company, founded in 2024 and headquartered in Los Angeles, conducts engineering and testing activities in Norway in cooperation with Nammo.
