LCI(L)
The Landing Craft Infantry (LCI) were several classes of landing craft used to land large numbers of infantry directly onto beaches during the Second World War. They were developed in response to a British request for seagoing amphibious assault ships capable of carrying and landing substantially more troops than their smaller Landing Craft Assault (LCA). The result was a small steel ship that could land 200 men, traveling from rear bases on its own bottom at a speed of up to 15 knots. Some 923 were built starting in 1943, serving in both the Pacific and European theaters, including a number that were converted into heavily armed beach assault support ships. The LCI(L) supplemented the small LCAs/ LCVPs as a way to get many troops ashore before a dock could be captured or built. As such, they were the largest dedicated beachable infantry landing craft (the larger Landing Ship Infantry (LSI) was a transporter for men and small craft such as the British LCA) in the Allied inventory ...

Brown Shipbuilding
The Brown Shipbuilding Company was founded in Houston, Texas, in 1942 as a subsidiary of Brown and Root (now KBR) by brothers Herman and George R. Brown to build ships for the U.S. Navy during World War II. Brown Shipbuilding Company ranked 68th among United States corporations in the value of World War II military production contracts. In 1941, Navy officials asked the Brown brothers to build four submarine chasers. The brothers had no shipbuilding experience, but had helped build Naval Air Station Corpus Christi. In 1942, the brothers formed Brown Shipbuilding and, with $9 million in Navy funding, built the Green's Bayou Fabrication Yard at the juncture of the Houston Ship Channel and Green's Bayou. After delivering the ships, Brown received orders for landing craft and more sub chasers, and eventually won an order for destroyer escorts at $3.3 million per ship. Between May 1943 and August 1944, Brown turned out 61 destroyer escorts, an average of one per week. Perhaps the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albina Engine & Machine Works
Albina Engine & Machine Works was a shipyard along the Willamette River in Portland, Oregon, United States. It was located in the Albina area of Portland along N. River Street and N. Loring Street. Albina Engine & Machine Works was founded in 1904. The shipyard produced a number of freighters during World War I, but operated mainly as a repair yard during the 1920s and 1930s. The Albina yard expanded its workforce and production during Portland's World War II shipbuilding boom. It specialized in producing subchasers, vessels designed to combat German U-boats. Albina Engine & Machine Works also built Landing Craft Support boats and cargo ships. Business declined in the post-war years, and Albina Engine & Machine Works was sold to the Dillingham Corporation around 1971.

Landing Craft Assault
Landing Craft Assault (LCA) was a landing craft used extensively in World War II. Its primary purpose was to ferry troops from transport ships to attack enemy-held shores. The craft derived from a prototype designed by John I. Thornycroft Ltd. of Woolston, Hampshire, UK. During the war it was manufactured throughout the United Kingdom in places as various as small boatyards and furniture manufacturers. Typically constructed of hardwood planking and selectively clad with armour plate, this shallow-draft, barge-like boat with a crew of four could ferry an infantry platoon of 31 and five additional specialist troops, to shore at 7 knots (13 km/h). Men generally entered the boat by walking over a gangplank from the boat deck of a troop transport as the LCA hung from its davits. When loaded, the LCA was lowered into the water. Soldiers exited by the boat's bow ramp. The LCA was the most common British and Commonwealth landing craft of World War II. Prior to July 1942, the ...

Landing Craft
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force (infantry and vehicles) from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States. Because of the need to run up onto a suitable beach, World War II landing craft were flat-bottomed, and many designs had a flat front, often with a lowerable ramp, rather than a normal bow. This made them difficult to control and very uncomfortable in rough seas. The control point (too rudimentary to call a bridge on LCA and similar craft) was normally at the extreme rear of the vessel, as were the engines. In all cases, they were known by an abbreviation derived from the official name rather than by the full title. History In the days of sail, the ship's boats were us ...

Commercial Iron Works
Commercial Iron Works was a manufacturing firm in Portland, Oregon, United States. Established in 1916, the company is best remembered today for its contribution to America's Emergency Shipbuilding Program during World War II. The company was founded in November 1916, by William T. Casey, Otto J. Hoak and Robert Boogs, on a site on the Willamette River just south of the Ross Island Bridge. Little is known about the company's early years, but it appears to have served diverse markets. For example, it placed a bid for the manufacture of 200 fire hydrants for the City of Portland in 1927, and supplied the high pressure outlet gates for the Unity Dam on the Burnt River near Baker, Oregon in 1937. The company is recorded as having built only one ship prior to World War II - a small 140-ton tender for the US Coast Guard in 1935. The CIW built the 25-ton tugboat Constance J for the Crown Willamette Paper Company. The Constance J was still in service as an active workboat as late as ...

Defoe Shipbuilding Company
The Defoe Shipbuilding Company was a small ship builder established in 1905 in Bay City, Michigan, United States. It ceased to operate in 1976 after failing to renew its contracts with the United States Navy. The site of the former company is now being developed for business and housing on the bank of the Saginaw River. Founding Harry J. Defoe organized the Defoe Boat and Motor Works in 1905 on the Saginaw River in Bay City, Michigan. At that time, the firm built "knock-down" boats and gasoline powered boats for business and pleasure. In 1917, the company got its first Navy contract for five Spent Torpedo Chasers. This order was followed in 1918 by an order for eight steel Tumor Mine Planters. From 1920 to 1939, the company built various types of government and commercial vessels and private yachts, including three 165-ft patrol boats, thirteen 100-ft patrol boats, fifteen 75-foot patrol boats and two harbor tugs for the U.S. Coast Guard. In 1931, Defoe built the '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Detroit Diesel Series 71
The Detroit Diesel Series 71 is a two-stroke diesel engine series, available in both inline and V configurations, manufactured by Detroit Diesel. The number 71 refers to the nominal displacement per cylinder in cubic inches, a rounding off of . Inline models included one, two, three, four and six cylinders, and the V-types six, eight, 12, 16 and 24 cylinders. The two largest V units used multiple cylinder heads per bank to keep the head size and weight to manageable proportions, the V-16 using four heads from the four-cylinder inline model and the V-24 using four heads from the inline six-cylinder model. This feature also assisted in keeping down the overall cost of these large engines by maintaining parts commonality with the smaller models. History The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938. The V-type first appeared in 1957.

Battle Of Anzio
The Battle of Anzio was a battle of the Italian Campaign of World War II that took place from January 22, 1944 (beginning with the Allied amphibious landing known as Operation Shingle) to June 5, 1944 (ending with the capture of Rome). The operation was opposed by German forces in the area of Anzio and Nettuno. The operation was initially commanded by Major General John P. Lucas, of the U.S. Army, commanding U.S. VI Corps with the intent to outflank German forces at the Winter Line and enable an attack on Rome.
