Information:  - USS Polaris ( AF - 11 ) was a Type C2 `` Liberty fleet '' standard freighter and an Aldebaran - class stores ship acquired from the United States Maritime Commission by the US Navy for World War II and the Korean War .  - The United States Maritime Service (USMS) was established in 1938 under the provisions of the Merchant Marine Act of 1936. The mission of the organization is to train people to become officers and crewmembers on merchant ships that form the United States Merchant Marine per Title 46 U.S. Code 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.  - South Korea, officially the Republic of Korea (ROK), is a sovereign state in East Asia, constituting the southern part of the Korean Peninsula.  - The Korean War (in South Korean , "Korean War"; in North Korean , "Fatherland Liberation War"; 25 June 1950  27 July 1953) began when North Korea invaded South Korea. The United Nations, with the United States as the principal force, came to the aid of South Korea. China came to the aid of North Korea, and the Soviet Union gave some assistance.  - The United Nations (UN) is an intergovernmental organization to promote international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The headquarters of the United Nations is in Manhattan, New York City, and experiences extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict.  - The United States Maritime Commission (MARCOM) was an independent executive agency of the U.S. federal government that was created by the Merchant Marine Act of 1936, passed by Congress on June 29, 1936, and replaced the United States Shipping Board which had existed since World War I. It was intended to formulate a merchant shipbuilding program to design and build five hundred modern merchant cargo ships to replace the World War I vintage vessels that comprised the bulk of the United States Merchant Marine, and to administer a subsidy system authorized by the Act to offset the cost differential between building in the U.S. and operating ships under the American flag. It also formed the United States Maritime Service for the training of seagoing ship's officers to man the new fleet.  - The United States Merchant Marine refers to either United States civilian mariners, or to U.S. civilian and federally owned merchant vessels. Both the civilian mariners, and the merchant vessels, are managed by a combination of the government and private sectors, and engage in commerce or transportation of goods and services in and out of the navigable waters of the United States. The Merchant Marine primarily transports cargo and passengers during peacetime; in times of war, the Merchant Marine can be an auxiliary to the United States Navy, and can be called upon to deliver military personnel and materiel for the military. Merchant Marine officers may also be commissioned as military officers by the Department of Defense. This is commonly achieved by commissioning unlimited tonnage Merchant Marine officers as Strategic Sealift Officers in the Naval Reserves.
