The US Navy has christened its newest Virginia-class attack submarine, the future USS Idaho (SSN 799).

As disclosed, the vessel was named during a ceremony held on March 16, at General Dynamics Electric Boat, in Groton, Connecticut.

The submarine, which began construction in 2017, will be the 26th Virginia-class fast attack submarine and the fifth U.S. Navy ship to be christened with the name Idaho. The last ship named Idaho was battleship BB 42, commissioned in 1919.

The Virginia-class, also known as the VA-class or 774-class, is a class of nuclear-powered fast attack submarines in service with the U.S. Navy. The submarines are designed for a broad spectrum of open-ocean and littoral missions.

They were conceived as a less expensive alternative to the Seawolf-class attack submarines, designed during the Cold War era, and are replacing older Los Angeles-class submarines.

The submarines are built to operate in the world’s littoral and deep waters while conducting anti-submarine warfare; anti-surface ship warfare; strike warfare; special operations forces support; intelligence, surveillance and reconnaissance; irregular warfare; and mine warfare missions.
