The Marine Corps’ mission aboard NS Newport has changed many times since 1894 when the Marine Corps first established a permanent tenant command in Newport. Today, Marine Corps Detachment Newport has the mission of training Marine Aviation Logistics Tactical Information System (known as ALTIS) specialists while providing administrative, logistical and headquarters support to more than
200 Marine Corps instructors and students attached to naval training commands in the region.
In 2010, the Marine Corps presence doubled with the relocation of the ALTIS course from Athens, Georgia, to the renovated Beirut Memorial Hall (named in honor of the nine Marines from Rhode Island who died in the 1983 Beirut Barracks bombing) on Coddington Point. The ALTIS School conducts a 30-week accession-level course where enlisted Marines earn the military occupational specialty of 6694. The course provides intensive training on hardware, software, networking, internetworking and system administrator skills for the stand-alone information technology systems and assets critical to a Marine Corps aircraft group in garrison and while deployed.
Beirut Memorial Hall is the epicenter of support for Marine Corps Training Command instructors and students in four Marine Corps military occupational specialty pipelines (4402, 4421, 4422 and 6694) as well as Marine Corps drill instructors at Officer Training Command, Newport. In addition, the Marine Corps Detachment provides support for Marines attached to the Naval Justice School, Naval War College, Naval Academy Preparatory School, Defense Institute of International of Legal Studies and Survival Evasion Resistance Escape East.
