About this Unit
The Marine Detachment (MARDET) aboard USS LEXINGTON (CVA-16) was established as part of the ship’s company during her active service in the U.S. Navy. MARDET’s primary roles included shipboard security, manning secondary batteries, ceremonial duties, and serving as a landing force if required. Throughout LEXINGTON’s distinguished career—including significant action in the Pacific during World War II and later as a training carrier—MARDET personnel contributed to both combat readiness and daily operations. The detachment was decommissioned along with the ship’s transition to a training vessel, marking the end of an era for Marines aboard the “Blue Ghost.”
