An armed merchantman is a merchant ship equipped with guns, usually for defensive purposes, either by design or after the fact. In the days of sail, piracy and privateers, many merchantmen would be routinely armed, especially those engaging in long distance and high value trade.
A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are usually faster and more manoeuvrable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations.
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.
The New York Shipbuilding Corporation was an American shipbuilding company that operated from 1899 to 1968, ultimately completing more than 500 vessels for the U.S. Navy, the United States Merchant Marine, the United States Coast Guard, and other maritime concerns. At its peak during World War II, NYSB was the largest and most productive shipyard in the world. Its best-known vessels include the destroyer USS Reuben James (DD-245), the cruiser USS Indianapolis (CA-35), the aircraft carrier USS Kitty Hawk (CV-63), the nuclear-powered cargo ship NS Savannah, and a quartet of cargo-passenger liners nicknamed the Four Aces.
Commerce raiding is a form of naval warfare used to destroy or disrupt logistics of the enemy on the open sea by attacking its merchant shipping, rather than engaging its combatants or enforcing a blockade against them.
The United States Maritime Administration (MARAD) is an agency of the United States Department of Transportation.
Its programs promote the use of waterborne transportation and its seamless integration with other segments of the transportation system, and the viability of the U.S. merchant marine. The Maritime Administration works in many areas involving ships and shipping, shipbuilding, port operations, vessel operations, national security, environment, and safety. The Maritime Administration is also charged with maintaining the health of the merchant marine, since commercial mariners, vessels, and intermodal facilities are vital for supporting national security, and so the agency provides support and information for current mariners, extensive support for educating future mariners, and programs to educate America's young people about the vital role the maritime industry plays in the lives of all Americans.
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 War Shipping Administration (WSA) was a World War II emergency war agency of the US government, tasked to purchase and operate the civilian shipping tonnage the US needed for fighting the war. Both shipbuilding under the Maritime Commission and ship allocation under the WSA to Army, Navy or civilian needs were closely coordinated though Vice Admiral Emory S. Land who continued as head of the Maritime Commission while also heading the WSA.
Hog Islanders is the slang for ships built to Emergency Fleet Corporation designs number 1022 and 1024. These vessels were cargo and transport ships, respectively, built under government direction and subsidy to address a shortage of ships in the United States Merchant Marine during World War I. American International Shipbuilding, subsidized by the United States Shipping Board, built an emergency shipyard on Hog Island just outside Philadelphia, Pennsylvania, at the site of the present-day Philadelphia International Airport.
The Emergency Fleet Corporation (EFC) was established by the United States Shipping Board, sometimes referred to as the War Shipping Board, on 16 April 1917 pursuant to the Shipping Act to acquire, maintain, and operate merchant ships to meet national defense, foreign and domestic commerce during World War I. The EFC was renamed the U.S. Shipping Board Merchant Fleet Corporation by act of Congress 11 February 1927. The Board and Corporation were abolished 26 October 1936 and their functions transferred to the U.S. Maritime Commission by the Merchant Marine Act of 29 June 1936.
The Merchant Marine Act of 1936 is a United States federal law. Its purpose is "to further the development and maintenance of an adequate and well-balanced American merchant marine, to promote the commerce of the United States, to aid in the national defense, to repeal certain former legislation, and for other purposes."
The maritime history of the United States is a broad theme within the history of the United States. As an academic subject, it crosses the boundaries of standard disciplines, focusing on understanding the United States' relationship with the oceans, seas, and major waterways of the globe. The focus is on merchant shipping, and the financing and manning of the ships. A merchant marine owned at home is not essential to an extensive foreign commerce. In fact, it may be cheaper to hire other nations to handle the carrying trade than to participate in it directly. On the other hand, there are certain advantages, particularly during time of war, which may warrant an aggressive government encouragement to the maintenance of a merchant marine.
A merchant navy or merchant marine or mercantile marine is the fleet of merchant vessels that are registered in a specific country. On merchant vessels, seafarers of various ranks and sometimes members of maritime trade unions are required by the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) to carry Merchant Mariner's Documents.
The United States merchant marine forces matured during the maritime history of the United States (1900–1999).
The Long Range Shipbuilding program was implemented by the U.S. Maritime Commission shortly after its establishment in 1937 as part of the mandate of the Merchant Marine Act of 1936 which stated that:
United States shall have a merchant marine
(a) sufficient to carry its domestic water-borne commerce and a substantial portion of the water-borne export and import foreign commerce of the United States and to provide shipping service on all routes essential for maintaining the flow of such domestic and foreign water-borne commerce at all times
(b) capable of serving as a naval and military auxiliary in time of war or national emergency,
(c) owned and operated under the United States flag by citizens of the United States insofar as may be practicable, and
(d) composed of the best-equipped, safest, and most suitable types of vessels, constructed in the United States and manned with a trained and efficient citizen personnel. It is hereby declared to be the policy of the United States to foster the development and encourage the maintenance of such a merchant marine.
USS Hunter Liggett (APA-14) was built as an Emergency Fleet Corporation (EFC) Design 1029 ship, launched as Palmetto State and shortly after renamed Pan America for operation as the United States Shipping Board (USSB) owned liner operated by the Munson Steamship Line on New York to South American service. The ship was acquired by the War Department in February 1939 and renamed Hunter Liggett for operation as the United States Army transport USAT Hunter Liggett mainly between New York and San Francisco.
USS Besboro (AG-66) was built as Caddopeak, a United States Shipping Board (USSB) Emergency Fleet Corporation Design 1049 cargo ship built by Albina Engine & Machine Works, launched 18 October 1918. From 1922 Caddopeak served several commercial shipping companies until sold in 1937 to Burns Steamship Company and renamed Lurline Burns. On 2 February 1942 the ship was delivered to the War Shipping Administration, allocated to the United States Army and operated by Burns and Alaska Steamship Company under an Army charter agreement.
West Compo was a steam cargo ship built in 1918–1919 by Northwest Steel Company of Portland for the United States Shipping Board as part of the wartime shipbuilding program of the Emergency Fleet Corporation (EFC) to restore the nation's Merchant Marine. The vessel was commissioned into the Naval Overseas Transportation Service (NOTS) of the United States Navy in January 1919 and after only one overseas trip was decommissioned four months later and returned to the USSB. Afterwards the vessel was largely employed on the Atlantic Coast of the United States to France route until mid-1921 when she was laid up and eventually broken up for scrap in 1936.
The Merchant Shipbuilding Corporation was an American corporation established in 1917 by railroad heir W. Averell Harriman to build merchant ships for the Allied war effort in World War I. The MSC operated two shipyards: the former shipyard of John Roach & Sons at Chester, Pennsylvania, and a second, newly established emergency yard at Bristol, Pennsylvania, operated by the MSC on behalf of the U.S. Shipping Board's Emergency Fleet Corporation (EFC).
