The US Navy’s USS Toledo (SSN 769) has returned to service after its eleven-month engineering overhaul at the Norfolk Naval Shipyard in Portsmouth, Virginia.
Refurbishment and modernization efforts, such as mast and periscope installation, as well as engine room tests, were conducted to extend its operational life.
Maintenance for the nuclear-powered attack submarine was carried out by 50 employees across the shipyard production shops.
All updates were run under the force’s Shipyard Infrastructure Optimization Program, which aims to meet nuclear fleet maintenance requirements while optimizing shipyard processes.
“An Engineered Overhaul is a marathon, and I appreciate all the significant efforts from the project team, crew, and contracting partners to keep pushing us to the finish line,” Norfolk Naval Shipyard Commander Captain Jip Mosman said.
SSN 769 is one of 20 Los Angeles-class submarines currently in service.

The submarine began its deployment in 1997, serving in drug interdiction missions in the Caribbean Sea and taking on reconnaissance roles during the Afghanistan War.
Its more recent deployments include port calls in Bahrain, Norway, and Scotland. SSN 769’s crew was given the Navy Unit Commendation award in 2020 for their eight-month intelligence collection deployment.
The submarine weighs 6,096 tons and can achieve submerged speeds greater than 34.5 miles (55.5 kilometers) per hour.
Its propulsion consists of an S6G pressurized water reactor with a 165-megawatt core, two steam turbines, and a secondary 325-horsepower propulsion motor.
