Engagement Superiority: How L3Harris’ Iver AUVs are Establishing the Hybrid Undersea Fleet

L3Harris is redefining the undersea battlespace with its Iver4 autonomous underwater vehicle (AUV) and breakthrough torpedo tube launch and recovery (TTL&R) technology. In a recent at-sea operation in the Mediterranean, with the U.K. Royal Navy under Project Scylla, L3Harris AUVs successfully conducted submarine launch and recovery operations, demonstrating a major step forward for the Royal Navy. This trial not only validated the Iver4’s capabilities but also marked a pivotal step toward a hybrid Navy fleet where crewed platforms leverage uncrewed platforms as force multipliers, delivering engagement superiority.

Project Scylla: A New Era in Underwater Warfare

Delivered under AUKUS Pillar 2, Project Scylla represents a pioneering collaboration between Australia, the United Kingdom and the United States (AUKUS) to fast-track next-generation undersea capabilities. By keeping stealth intact, TTL&R technology enhances survivability and tactical reach in contested waters. AUVs can take on routine operations, freeing the submarine to focus on high-priority missions.

L3Harris, a leading developer of this capability, has now proven the concept in both domestic and allied submarine platforms, validating the technology’s readiness and system interchangeability, a key AUKUS goal.

Operational Agility Below the Surface

The ability to recover AUVs into a moving, submerged submarine delivers a significant tactical advantage. Manned platforms remain in safe or covert positions while AUVs conduct high-risk activities. Upon return, the AUV brings back high-fidelity data for mission planning, seamlessly integrating manned-unmanned teaming into submarine operations.

Autonomy That Delivers in the Real World

Designed to thrive in multi-domain, contested environments, L3Harris' autonomous systems reduce operational risks to sailors and platforms while broadening mission capabilities. With advanced payload integration, the Iver4 detects, tracks and helps neutralize undersea threats—all without compromising stealth or mission integrity. Backed by extensive real-world experience and proven performance, L3Harris continues to push the limits of undersea warfare capabilities, ensuring the future of a hybrid Navy fleet.
