Iver Suite of Autonomous Underwater Vehicles

Versatile Undersea Solutions for Critical Missions

L3Harris is a pioneer in autonomous underwater vehicle (AUV) technology, delivering proven capabilities for defense and commercial operations worldwide. Our Iver family of modular, open-architecture AUVs excels at long-range surveys, multi-domain ISR, and mine warfare missions. Engineered for maximum operational flexibility, Iver systems deploy from surface ships, piers, or clandestinely via submarine torpedo tubes, adapting seamlessly to evolving mission requirements. With decades of operational heritage and continuous innovation, the Iver suite provides the reliable, mission-ready performance that modern undersea operations demand.

Iver3 is one of the first commercially developed AUVs. Ideal for coastal applications such as sensor development, general survey work, sub-surface security, research, and environmental monitoring.

L3Harris to Provide Autonomous Underwater Capability for US Navy Submarines

Torpedo Tube Launch and Recovery system

L3Harris Technologies has received an Other Transaction Authority contract from the Department of War’s Defense Innovation Unit to deliver the Torpedo Tube Launch and Recovery (TTL&R) system, which deploys and retrieves the company’s Iver4 900 autonomous underwater vehicles (AUVs) through submarine torpedo tubes.
