USMS meaning in Regional ?

The United States Maritime Service (USMS) was established in 1938 under the provisions of the Merchant Marine Act of 1936 as voluntary organization to train individuals to become officers and crewmembers on merchant ships that form the United States Merchant Marine per 46 U.S.C. § 51701. Heavily utilized during World War II, the USMS has since been largely dissolved and/or absorbed into other federal departments, but its commissioned officers continue to function as administrators and instructors at the United States Merchant Marine Academy and the several maritime academies.
