L3Harris Technologies has received its largest full-rate production contract for communications systems from General Dynamics Electric Boat to deliver 26 shipsets for Virginia- and Columbia-class submarines.

The follow-on award includes production for both submarine classes through 2033, with support extendable to future Columbia-class platforms and allied navies worldwide.

This award builds on L3Harris’ decades-long legacy of supporting U.S. Navy submarine programs, including the Ohio- and Los Angeles-class submarines. Virginia-class submarines are nuclear-powered, fast-attack vessels designed for both littoral and deep-sea operations.

The Columbia-class submarines, under development, will replace the Ohio-class ballistic missile submarines as the cornerstone of navy’s sea-based nuclear deterrent.

“The ability for submarines to operate undetected is vital to the U.S. Navy’s strategic advantage,” said Nino DiCosmo , President, Maritime, Space and Mission Systems, L3Harris.

“With decades of experience in submarine technology and in partnership with General Dynamics Electric Boat, L3Harris will deliver highly reliable, undetectable communications systems to enhance operational effectiveness.”

To remind, the US Navy recently selected L3Harris to develop, test, and manufacture Red Wolf vehicles for the US Marine Corps’ Precision Attack Strike Munition program.
