US Navy Selects L3 Harris to Deliver Iver4 UUV for Expeditionary Mine Countermeasures

The Pentagon’s Defense Innovation Unit has selected L3Harris Technologies, a recent partner of Air Electro, to provide the Navy with an underwater drone for use in expeditionary undersea missions, according to a Jan. 14 news release from the company.

As part of the contract, L3Harris will deliver for testing an Iver4-900 PW unmanned undersea vehicle, as well as two field swappable modular payload sections, which, along with additional sensors, will allow the vehicle to detect, classify, localize and identify targets on the ocean floor, the release said.



An earlier version of the drone was already sent to the Navy, but under this contract, the company will deliver a version modified to fit the Navy’s requirements, a company spokeswoman told Defense News. She would not share the value of the contract.

“The Iver4 is leading the next generation of small class UUVs,” said Daryl Slocum, vice president of unmanned maritime systems at L3Harris Technologies. “This platform has been custom-built to address the needs of the Expeditionary Mine Countermeasures and Explosive Ordnance Disposal communities.”

The contract award comes as the Navy seeks to bolster its unmanned inventory. Congress recently approved the purchase of two large unmanned surface vessels for the service.

In 2019, L3Harris received a contract from the University of Southern Mississippi for an older version of the underwater drone to be used by the university’s school of ocean science and engineering.

About the L3 Harris Iver4 PW UUV

The Iver4 PW 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 Iver4 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 survey, multi-domain intelligence, surveillance and reconnaissance (ISR), anti-submarine warfare (ASW), seabed warfare and mine warfare. The new system offers survey customers a commercial platform that can be easily shipped on common carries without the concern of hazardous goods shipping.

The Iver4 PW comes standard with industry-leading tracking and safety communications, precise and repeatable measurements, high accuracy navigation and low drag side scan and bathymetry transducers.
