Los Angeles-class sub USS Toledo returns to fleet after engineering overhaul

The US Navy’s Los Angeles-class submarine USS Toledo (SSN 769) has returned to the fleet following the completion of its engineered overhaul at Norfolk Naval Shipyard (NNSY).

As disclosed, the overhaul for the vessel, which joined the fleet on April 19, 2025, involved maintenance requiring drydocking for refurbishment and modernization throughout the boat to extend its operational life.

The team held strategic planning sessions for attaining equipment and improving services, having ongoing meetings with the crew, and accomplishing advanced work at Toledo’s homeport in Groton, Connecticut, prior to the boat’s arrival at NNSY.

In addition, the project team performed a large amount of work pier side while the boat’s hosting dry dock underwent structural upgrades as part of the navy’s Shipyard Infrastructure Optimization Program.

The operations control center was established near the boat, serves as a dedicated hub for resolving any work stoppages.

Following its undocking in May 2024, Toledo’s project team focused on moving the crew back onboard, completing jobs like mast and periscope installation, and conducting engine room testing.

“The Toledo team and all the codes, shops, and personnel in America’s Shipyard who supported the efforts on the boat should be very proud,” said Shipyard Commander Captain Jip Mosman.
