CDR SALAMANDER: Condition of the Navy’s Amphibious Fleet And Its Impacts on Marines: the View from GAO. “Amphibious warfare ships are critical for Marine Corps missions, but the Navy has struggled to ensure they are available for operations and training. In some cases, ships in the amphibious fleet have not been available for years at a time. The Navy and Marine Corps are working to agree on a ship availability goal but have yet to complete a metrics-based analysis to support such a goal. Until the Navy completes this analysis, it risks jeopardizing its ability to align amphibious ship schedules with the Marine Corps units that deploy on them.”
