Commemoration Virtual Tour


As the ship was quietly and uniquely commissioned two years ago, the U.S. Navy, the Navy League of the United States Hampton Roads, Senator Carper, and Delaware’s Governor Carney hosted an event commemorating the commissioning of the USS Delaware (SSN 791).

While the event was a greatly reduced version similar to what had been planned for 2020, the public is invited to experience a virtual Tour of the ship.


USS Delaware (SSN 791) Commissioning


It is highly unusual for a ship to be commissioned outside of a Navy port where it has been built but Senator Tom Carper prevailed upon the United States Navy to bring the submarine to Wilmington so Delawareans could participate in the historic celebration. Due to COVID-19, a commissioning ceremony was cancelled. The ceremony for the USS Delaware (SSN 791) was expected to have an attendance of 5,000 at the Port of Wilmington. As a result, the USS Delaware (SSN 791) became the first U.S. submarine to be commissioned while underway…and underwater. She is home ported in Groton, CT. The USS Delaware (SSN 791) is a Virginia-class fast-attack submarine. It is 7,800 tons and 377 feet in length with a beam of 34 feet and can operate at more than 25 knots submerged. It is designed with a reactor plant that will not require refueling during the planned life of the board.

What is Commissioning


After a vessel has completed rigorous testing and sea trials, the shipbuilder then deems the ship capable of performing her designed mission and prepared to join the fleet. For all purposes of law and tradition, a vessel becomes a United States Ship at a commissioning ceremony. The Commanding Officer and crew come aboard and are entrusted with the responsibility of maintaining and operating their boat in peacetime and under conditions of war. Each crew member becomes a plank owner of the newly commissioned vessel, a distinct time-honored privilege. The service life of a submarine is 50 years with 136 stationed aboard.
