L3Harris Technologies to Provide Unmanned Undersea Vehicle to U.S. Navy

L3Harris Technologies has been selected by the U.S. Navy and the Defense Innovation Unit (DIU) to provide an Unmanned Undersea Vehicle (UUV) for expeditionary undersea missions for U.S. military forces.

DIU, which accelerates commercial technology to solve national security solutions, awarded an Other Transaction Agreement (OTA) to L3Harris for the U.S. Navy’s Next Generation Small-Class Maritime Expeditionary Mine Countermeasures Unmanned Undersea Vehicle (MEMUUV) program.

This award includes the delivery and testing of an Iver4-900 UUV and two field swappable modular payload sections, including real aperture and Synthetic Aperture Sonars (SAS). Additional sensors, swappable battery chemistries, and data solutions are included with the prototype system to provide U.S. military forces with a highly capable UUV that can detect, classify, localize, and identify targets on the ocean floor and in the water column in support of Expeditionary Mine Countermeasures (ExMCM), Explosive Ordnance Disposal (EOD), and undersea search operations.

“The Iver4 is the culmination of many years of UUV development, customer feedback and application knowledge for military applications,” said Daryl Slocum, Vice President and General Manager, Unmanned Maritime Systems, L3Harris. “This platform has been custom-built to address the needs of the ExMCM and EOD communities. With its flexible payload, transportable package, extended endurance and high-performance accuracy, the Iver4 is leading the next generation of small class UUVs. We are honored to receive DIU’s award and look forward to bringing
the Iver4 to the warfighter.”

Iver4 PW UUV

The Iver4 PW Unmanned Undersea Vehicle (UUV) offers users a new 300-meter workhorse system featuring long duration capability and no shipping restrictions with L3Harris OceanServer’s Lithium-free standard design.

The UUV comes standard with rechargeable NiMH battery packs supporting up to 20-hour run times of 40 nautical miles mission duration for long ingress/egress missions (40-hour run times of 80 nautical miles available with Li-Ion battery – payload and current dependent).

The Iver4 PW is the first in a family of advanced UUVs to address a wide variety of missions, including commercial and defense applications such as long-range surveys, multi-domain intelligence, surveillance and reconnaissance (ISR), anti-submarine warfare (ASW), seabed warfare and mine warfare.

The UUV comes standard with industry-leading tracking and safety communications, precise and repeatable measurements, high accuracy navigation and low drag side scan and bathymetry transducers.
