- The United States Navy began sea trials for USS Tortuga after a long-term modernization, marking the ship’s first deployment since 2014.
- The trials aim to validate upgraded engineering and combat systems before the vessel can be certified for operational service.
The United States Navy sent the dock landing ship USS Tortuga (LSD 46) to sea trials from Naval Station Norfolk, marking the vessel’s first time underway since 2014 following an extended modernization effort.
The trials are intended to verify that the ship’s upgraded systems and engineering improvements are fully operational, as the Navy works to return long-idle amphibious platforms to service.
According to the Navy, USS Tortuga is in the final phase of a multi-year modernization program carried out by BAE Systems and managed by the Mid-Atlantic Regional Maintenance Center. The sea trials will assess the ship’s engineering performance, onboard systems, and combat readiness before it can be certified for operational deployment.
The ship’s return to sea follows nearly a decade out of service. During the trials, the crew will evaluate propulsion, navigation, communications, and combat systems under real operating conditions.
The Navy said the purpose of the sea trials is to confirm that all upgrades function as intended and that the ship meets required standards for safety and mission capability. Certification of the vessel will depend on the successful completion of these tests.
USS Tortuga is a Whidbey Island-class dock landing ship designed to support amphibious operations, including the transport and launch of landing craft, vehicles, and Marines. These ships play a central role in enabling expeditionary operations from sea to shore.

As part of the modernization effort, the vessel underwent extensive work on its mechanical and electrical systems, as well as updates to key onboard equipment. While specific upgrade details were not disclosed, such programs typically include improvements to propulsion systems, command and control infrastructure, and survivability features.
BAE Systems, the primary contractor, has been responsible for executing the modernization work, while the Mid-Atlantic Regional Maintenance Center oversaw the project.
The return of USS Tortuga comes at a time when the Navy continues to manage an aging amphibious fleet while maintaining operational commitments. Extended maintenance periods and modernization programs have become a recurring feature as ships remain in service longer than originally planned.
