Huntington Ingalls Industries’ (HII) Newport News Shipbuilding division has begun scheduled overhaul work on the nuclear-powered submarine USS Boise (SSN 764).

The Los Angeles-class submarine arrived at Newport News on Monday and will undergo planned maintenance and repair activities pierside before it will be moved to a dry dock in January 2019. The extended engineering overhaul, which includes system upgrades, will take 25 months and is expected to be completed in 2021.

“Submarine fleet support work represents a significant increase in our workload and provides a critical balance for public and private shipyards,” said Bill Smith, Newport News’ vice president of fleet support programs. “We have been preparing for Boise’s availability and looking forward to returning the submarine back to the fleet.”

Newport News laid USS Boise’s keel in August 1988, and the submarine was delivered to the U.S. Navy in September 1992.
