Advanced systems built by L3Harris and installed onboard both USS Massachusetts and USS Idaho enable crews to operate with confidence in contested undersea environments.

The U.S. Navy commissioned both Virginia-class submarines in ceremonies this spring.

USS Massachusetts joined the fleet on March 28 in Boston Harbor, followed by USS Idaho on April 25 in Groton, Connecticut.

Technologies that Enable the Mission

L3Harris provides communications, electronic warfare, acoustic sensors and mission systems, and power distribution equipment to Virginia-class submarines, critical capabilities that enable crews to maintain situational awareness, communicate securely and complete missions in the most demanding environments. When a submarine submerges, there's no room for equipment failure. Sailors depend entirely on systems that must perform flawlessly.

'Watching these crews take their stations for the first time reinforces why reliability is our paramount requirement,' said Nino DiCosmo, President, Maritime, L3Harris. 'The men and women of the Silent Service operate in conditions where technology must work without fail, every time.'

The company's communications systems deliver secure connectivity in denied environments. Electronic warfare capabilities provide protection against evolving threats. Acoustic sensors extend detection range and provide early warning of advancing potential threats. Mission systems integrate these capabilities, allowing crews to focus on their mission, not their equipment.

Commitment that Continues

As USS Massachusetts and USS Idaho begin operational careers, L3Harris will continue supporting the submarines throughout their service lives, providing technologies, training and sustainment that enable mission success while investing in next-generation capabilities for future submarine fleets.

The commissioning ceremonies celebrated milestones. The real work continues every day, aboard submarines where sailors depend on technology that performs without fail.
