Navy lays the keel

On 24th August 2020, the U.S. Navy held a keel-laying ceremony in Groton, Connecticut and officially began the construction of a new Virginia-class attack submarine USS Idaho (SSN-799).

Sponsor Teresa Stackley laid the keel of the USS Idaho (SSN-799) on August 24, 2020 at the Quonset Point Facility of General Dynamics Electric Boat in North Kingston, Rhode Island

The U.S. Navy held a ceremony with former Idaho Governor Dirk Kempthorne Monday to name Nicholas Meyers as the USS Idaho (SSN-799) commander. Its crew of 135 sailors will also feature three native Idahoans.

General Dynamics Electric Boat Division is constructing this $2.44 billion piece of equipment at a shipyard in Quonset Point, Rhode Island. The submarine is 377 feet/114.8 m long, can travel up to 25 knots/28 mph/46.3 km/h and is capable of diving 800 feet/244 m.

The future USS Idaho (SSN-799) will be the fifth U.S. naval vessel named after the Gem State. The USS Idaho (SSN-799) will be the 26th submarine of the Virginia-class which is the most advanced nuclear submarine of the U.S. Navy.

The USS Idaho (SSN-799) will be the fifth ship to represent Idaho, but the first in more than a century. The last one was a battleship that played a crucial role in the Battle of Iwo Jima during World War II.
