War Shipping Administration
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 United States 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. Establishment A shortage of vessels further complicated by requirements to take vessels out of service for conversion and armament was of concern at the highest levels, including the President. Particular concern that available shipping would not be used effectively led to his establishment immediately on the nation's active entry into the war of the Strategic Shipping Board composed of the Chairman of the Maritime Commission, Army Chief of Staff, Chief of Naval Operations and Mr. Harry Hopkins reporting directly to the President ...

Corundum
Corundum is a crystalline form of aluminium oxide () typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. Corundum has two primary gem varieties: ruby and sapphire. Rubies are red due to the presence of chromium, and sapphires exhibit a range of colors depending on what transition metal is present. A rare type of sapphire, padparadscha sapphire, is pink-orange. The name "corundum" is derived from the Tamil- Dravidian word ''kurundam'' (ruby-sapphire) (appearing in Sanskrit as ''kuruvinda''). Because of corundum's hardness (pure corundum is defined to have 9.0 on the Mohs scale), it can scratch almost all other minerals. It is commonly used as an abrasive on sandpaper and on large tools used in machining metals, plastics, and wood. Emery, a variety of corundum with no value a ...

Maritime Commission
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, which was passed by Congress on June 29, 1936, and was abolished on May 24, 1950. The commission 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. As a symbol of the rebirth of the U.S. Merchant Marine and Merchant Shipbuilding under the Merchant Marine Act, the first vessel contracted for ...

South San Francisco
South San Francisco is a city in San Mateo County, California, United States, located on the San Francisco Peninsula in the San Francisco Bay Area. The city is colloquially known as "South City". The population was 66,105 at the 2020 census. History Prior to European exploration, the northern San Francisco peninsula was inhabited by the Ramaytush, a linguistic sub-group of the Ohlone people. Their village of Urebure on San Bruno Creek was visited by the Gaspar de Portolà expedition in 1769; remains of long-term (5,000+ years) inhabitancy and seasonal encampments have been examined at the Siplichiquin and Buckeye shell-mounds on San Bruno Mountain. Charcoal-sampling indicates these 3,000+ year old sites may have been actively occupied early in the Spanish colonial period (late 1700s). The delta of Colma Creek was formerly an important habitat for the waterfowl known to be hunted by the Ramaytush in historic times, and archaeologic sites have been recorded near the creek. ...

Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...
