US Navy launches new Virginia-class submarine USS Idaho

One of the US Navy’s newest attack submarines, the future USS IDAHO (SSN 799), was launched from General Dynamics Electric Boat’s shipyard into the Thames River on August 6, 2024.

The launch, also known as “float off,” marks a construction milestone in the life of a ship, when it moves from the shipbuilder’s facilities and into the water for the first time to begin final outfitting, testing, and crew certification

Submarine sponsor Terry Stackley christened the boat on March 16, 2024. The submarine began construction in 2017 and will be the 26th Virginia-class fast attack submarine to deliver to the fleet and the fifth U.S. Navy ship named for the state. The last ship named Idaho was battleship BB 42, commissioned in 1919.

“IDAHO will be a valuable national asset and source of pride for our Sailors, the shipbuilders and all Americans for years to come,” said Capt. Mike Hollenbach, Virginia Class Submarine program manager.

Virginia submarines have enhanced stealth, sophisticated surveillance capabilities, and special warfare enhancements that enable them to meet the US Navy’s multi-mission requirements.
