MV Diamond Knot
The was a C1-M-AV1 ship owned by the War Shipping Administration. She was operated by United States Lines from 1944 to 1947 under a bareboat under charter with the Maritime Commission and War Shipping Administration for World War II. In 1947 she was operated by the Alaska Steamship Co. She sank in the Strait of Juan de Fuca on the night of August 12, 1947, after a collision with the SS ''Fenn Victory''. The sinking resulted in the largest collision cargo loss in the waters of the Pacific Coast to that time. The ship was carrying a large cargo of canned salmon, most of which was subsequently recovered, repackaged, and sold. The wreck remains on the seafloor where it originally sank, at a depth of 70 to 130 ft, and is a popular spot for recreational SCUBA divers DCS Films See also * |
Type C1 Ship
Type C1 was a designation for small cargo ships built for the United States Maritime Commission before and during World War II. Total production was 493 ships built from 1940 to 1945. The first C1 types were the smallest of the three original Maritime Commission designs, meant for shorter routes where high speed and capacity were less important. Only a handful were delivered prior to Attack on Pearl Harbor, Pearl Harbor. But many C1-A and C1-B ships were already in the works and were delivered during 1942. Many were converted to military purposes including troop transports during the war. The Type C1-M ship was a separate design, for a significantly smaller and shallower Draft (hull), draft vessel. This design evolved as an answer for the projected needs for military transport and supply of the Pacific Ocean theater of World War II. Type C1 ships under the control of the British Ministry of War Transport took an Empire ship, Empire name even if built with another name e.g. ''C ...

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 ...

Consolidated Steel Corporation
Consolidated Steel Corporation (formed 18 December 1928) was an American steel and shipbuilding business. Consolidated built ships during World War II in two locations: Wilmington, California and Orange, Texas. It was created in 1929 by the merger of Llewellyn Iron Works, Baker Iron Works and Union Iron Works, all of Los Angeles. Orange shipyard The Orange, Texas shipyard lay on the banks of the Sabine River (Texas-Louisiana), Sabine River, a few miles upstream of the Sabine Pass that grants access to the Gulf of Mexico. () It was expanded in 1940 when Consolidated Steel was awarded destroyer contracts from the U.S. Navy. They were the Orange Car & Steel Company and Southern Dry Dock & Shipbuilding Company before the war. After the war the yard became a U.S. Steel fabrication plant. Steel sold to Signal International and then sold to Westport Orange Shipyard, LLC. At its peak durning the war, it employed 20,000 people. The first ship launched was the destroyer on March 2, ...

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 ...

United States Lines
United States Lines was the trade name of an organization of the United States Shipping Board (USSB), Emergency Fleet Corporation (EFC) created to operate German liners seized by the United States in 1917. The ships were owned by the USSB and all finances of the line were controlled by the EFC. Among the notable ships of this period was , a contender for largest ship in the world for a time. Eventually the line was sold and went private to continue operating as a transatlantic shipping company that operated cargo services from 1921 to 1989, and ocean liners until 1969—most famously, . 1920s United States Lines was the trade name of the United States Shipping Board's Emergency Fleet Corporation (EFC) organization created to operate the large German liners seized by the United States in 1917. By 1925 the corporation operated ex-German liners ''Leviathan'', , , and the USSB built ships and in service between New York and Europe. On 15 November 1921 the line began operating ...

Alaska Steamship Co
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

3-inch/50-caliber Gun
The 3"/50 caliber gun (spoken "three-inch fifty-caliber") in United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 calibers long (barrel length is 3 in × 50 = ). Different guns (identified by Mark numbers) of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1890 through to 1994 on a variety of combatant and transport ship classes. The gun is still in use with the Spanish Navy on ''Serviola''-class patrol boats. Early low-angle guns The US Navy's first 3"/50 caliber gun (Mark 2) was an early model with a projectile velocity of per second. Low-angle (single-purpose/non-anti-aircraft) mountings for this gun had a range of 7000 yards at the maximum elevation of 15 degrees. The gun entered service around 1900 with the s, and was also fitted to s. By World War II these guns were found only on a few Coast Guard cutters and Defensively Equipped Merchant Ships.

Caliber (artillery)
In artillery, caliber or calibredifference in British English and American English spelling is the internal diameter of a gun barrel, or - by extension - a relative measure of the barrel length. Rifled barrels Rifled barrels introduce ambiguity to measurement of caliber. A rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land. Projectiles fired from rifled barrels must be of the full groove to groove diameter to be effectively rotated by the rifling, but the caliber has sometimes been specified as the land to land diameter before rifling grooves were cut. The depth of rifling grooves (and the consequent ambiguity) increases in larger calibers. Steel artillery projectiles may have a forward bourrelet section machined to a diameter slightly smaller than the original land to land dimension of the barrel and a copper driving band somewhat larger than the groove to groove diameter t ...

Dual-purpose Gun
A dual-purpose gun is a naval artillery mounting designed to engage both surface and air targets. Description Second World War-era capital ships had four classes of artillery: the heavy main battery, intended to engage opposing battleships and cruisers of 305 mm to 457 mm (12 inch to 18 inch); a secondary battery for use against enemy destroyers of 152 mm to 203 mm (6 inch to 8 inch); heavy anti-aircraft guns of 76 mm to 127 mm (3 inch to 5 inch), which could create barrages to knock out airplanes at a distance; finally, light rapid-fire anti-aircraft batteries (A/A) to track and bring down aircraft at close range. The light A/A was dispersed throughout the ship and included both automatic cannons of 20 mm to 40 mm (.787 inch to 1.57 inch) and heavy machine guns of 12.7 mm to 14.5 mm (.50 inch to .58 inch). During World War II, the US Navy, Royal Navy, the French Navy, and the Imperial Japanese Navy combined the secondary battery with the heavy anti-aircraft guns, creating a d ...

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seeba ...

Anti-aircraft Warfare
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes Surface-to-air missile, surface based, subsurface (Submarine#Armament, submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defense, Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the World War II, Second World War, the Soviet Union, and modern NATO a ...

Chartering (shipping)
Chartering is an activity within the Maritime transport, shipping industry whereby a ship-owner, shipowner hires out the use of their vessel to a charterer. The contract between the parties is called a charterparty (from the French ''"charte partie"'', or "parted document"). The three main types of charter are: demise charter, voyage charter, and time charter. The charterer In some cases a charterer may own cargo and employ a shipbroker to find a ship to deliver the cargo for a certain price, called freight rate. Freight rates may be on a per-ton basis over a certain route (e.g. for iron ore between Brazil and China), in Worldscale points (in case of oil tankers) or alternatively may be expressed in terms of a total sum - normally in U.S. dollars - per day for the agreed duration of the charter. A charterer may also be a party without a cargo who takes a vessel on charter for a specified period from the owner and then trades the ship to carry cargoes at a profit above the hire r ...
