Norfolk Naval Shipyard Completes Engineered Refueling Overhaul of USS Wyoming (SSBN 742)

The U.S. Navy Ohio-class nuclear ballistic missile submarine USS Wyoming (SSBN 742) has returned to the fleet following completion of its Norfolk Naval Shipyard (NNSY) Engineered Refueling Overhaul (ERO) Oct. 9.

An ERO is a complex, major shipyard availability during which the submarine is refueled and upgraded before returning to sea to support the country’s nuclear deterrence strategy. In addition to Wyoming’s refueling, NNSY modified the ship in accordance with Enlisted Women at Sea ship alterations.

Wyoming has been at NNSY since January 2018 undergoing refueling and modernization, and  successfully undocked on Nov. 6 last year.

The shipyard project team achieved several successes during the overhaul, including its Strategic Weapons Test team setting a record for Missile Operational Sequence Testing, marking the fastest completion of this evolution during an ERO. NNSY completed missile operational testing in eight weeks, breaking its previous record of 10.5 weeks on USS Rhode Island (SSBN 740).

“Now that this overhaul is complete, Wyoming can carry on with the Department of Defense’s number one mission of nuclear deterrence as we continue preparations for the transition to the Columbia-class submarines,” said Rear Adm. John Spencer, Commander, Submarine Group Ten. “I am well aware that completing this scale of work requires an immense amount of teamwork between the ship crew and all of our teammates, both civilian and uniformed, at Norfolk Naval Shipyard, and I appreciate their collective efforts.”

“Ship repair is a team sport,” said Project Superintendent Brian Slivinski. “The whole team, from the deckplate level mechanics to the support organizations to Ship’s Force, everybody worked really well together with a common goal. Any challenge that was presented, we’d tackle as a team. We had a mindset of controlling our own destiny, which was very beneficial to us.”

This is the last in a line of eight East Coast Trident submarine Engineered Refueling Overhauls at NNSY which began with USS Florida (SSGN-728) in 2003.

Homeported in Kings Bay, Georgia, Wyoming is one of the United States’ most vital strategic assets, and combined with the other Ohio-class submarines, makes up one leg of the nuclear triad.
