USS Tripoli is an America-class amphibious assault ship in the United States Navy. Hull number LHA-7 identifies it as the second ship of its class. It is forward deployed to Sasebo, Japan, and serves as flagship for Expeditionary Strike Group 7 and Commander, Task Force 76.

Tripoli supports aviation-led expeditionary operations. It can embark Marine aircraft including F-35B Lightning II fighters and MV-22 Osprey tiltrotors, alongside helicopters and support aircraft. The ship carries Marines, sailors, vehicles and command staff for missions ranging from crisis response to maritime security. Its forward deployment places an amphibious command platform and short-take-off combat aircraft within the US Seventh Fleet area while allowing temporary operations farther west.

Key Issues

Fleet deployment

Tripoli completes a six-month deployment

On 14 March 2026, the United States said a larger Pacific amphibious force was moving towards the Middle East, with Tripoli at the centre of the deployment. The force included Marines, sailors, aircraft and supporting ships drawn from the Seventh Fleet area.

Tripoli and the 31st Marine Expeditionary Unit later supported maritime security in the Central Command area. The ship returned to Sasebo on 27 July after six months operating across the Fifth and Seventh Fleet areas. It resumed its forward-deployed role as flagship for Expeditionary Strike Group 7 and Commander, Task Force 76. The return ended the deployment rather than the ship's permanent Pacific assignment.
