Calmar Steamship Co
Calmar Steamship Company was a proprietary subsidiary of the Bethlehem Steel founded in New York City in 1927. Bethlehem Steel Company founded Calmar Steamship Company and other steamship companies after finding general shipping companies could not meet the company's needs in a timely manner. At the time Bethlehem Steel Company was the second-largest steelmaker in the United States and the world, only behind U.S. Steel. Calmar Steamship Company shipped Bethlehem Steel Company products from the Atlantic coast to the Pacific coast. On the return trip, Calmar Steamship Company would bring lumber products from the Pacific coast to the Atlantic coast. Calmar Steamship Company closed in 1976, as United States steel manufacture declined in the 1960s.

SS Hagerstown Victory
SS ''Hagerstown Victory'' was a Victory ship-based troop transport built for the U.S. Army Transportation Corps (USAT) late in World War II under the Emergency Shipbuilding program. It saw service in the European Theater of Operations during 1945 and in the immediate post-war period repatriating U.S. troops. ''Hagerstown Victory'' was one of 97 cargo Victory ships converted to a troopship. ''Hagerstown Victory'' was one of many of the new 10,500-ton class ships known as Victory ships. Victory ships were designed to replace the earlier Liberty ships, which were intended to be used just for World War II. Victory ships, on the other hand, were designed to last longer and serve the U.S. Navy after the war. The Victory ship differed from a Liberty ship in that they were faster, longer, wider, taller, had a thinner stack set farther toward the superstructure and had a long raised forecastle.

5 Inch (127 Mm)/38 Caliber Gun
The Mark 12 5"/38 caliber gun was a United States dual-purpose naval gun, but also installed in single-purpose mounts on a handful of ships. The 38 caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low-angle gun and 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 38 calibers long. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun. However, except for the barrel length and the use of semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft. The 5"/38 entered service on , commissioned in 1934, the first new destroyer design since the last ''Clemson'' was built in 1922. The base ring mount, which improved the effective rate of fire, entered service on , commissioned i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4"/50 Caliber Gun
The 4″/50 caliber gun (spoken "four-inch-fifty-caliber") was the standard low-angle, quick-firing gun for United States, first appearing on the monitor and then used on "Flush Deck" destroyers through World War I and the 1920s. It was also the standard deck gun on S-class submarines, and was used to rearm numerous submarines built with guns early in World War II. United States naval gun terminology indicates the gun fired a projectile in diameter, and the barrel was 50 calibers long. Design The original 4-inch/50 caliber Mark 7 gun, M1898, serial nos. 213–254, 257–281, 316–338, was an entirely new high-power design built-up gun with a tube, jacket, hoop, locking ring and screw breech. Gun No. 213 had a liner. The gun was described as a gun but with a 4-inch bore in the 1902 handbook, this indicated its higher power and also the fact the barrel was actually more the size of a 5-inch/40 caliber gun than a 4-inch gun. The ammunition was about heavier than a 4-inch/40 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3"/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.

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 ...

United States Navy Armed Guard
United States Navy Armed Guard units were established during World War II and headquartered in New Orleans.World War II U.S. Navy Armed Guard and World War II U.S. Merchant Marine, 2007-2014 Project Liberty Ship, Project Liberty Ship, P.O. Box 25846 Highlandtown Station, Baltimore, M/ref> The purpose of the guard was to man the deck guns of merchant ships to provide a nominal defense against attack. This was to counter the constant danger presented by enemy submarines, surface raiders, fighter aircraft and bombers. There was a shortage of escort vessels to provide the merchant vessels with adequate protection. The NAG had three training centers, at Norfolk, Virginia; San Diego, California; and Gulfport, Mississippi. At the end of the war, there were 144,857 men serving in the Navy Armed Guard on 6,200 ships.Armed Guard - Sea Lane Vigilantes, Project Liberty Ship, 201/ref> Unit composition The United States Navy Armed Guard (USNAG) were U.S. Navy gun crews consisting o ...

Liberty Ships
Liberty ships were a ship class, class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. Their production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types during World War I. The immensity of the effort, the number of ships built, the role of Rosie the Riveter, female workers in their construction, and the survival of some far longer than their original five-year desig ...

Victory Ship
The Victory ship was a class of cargo ship produced in large numbers by North American shipyards during World War II to replace losses caused by German submarines. They were a more modern design compared to the earlier Liberty ship, were slightly larger and had more powerful steam turbine engines giving higher speed to allow participation in high speed convoys and make them more difficult targets for German U-boats. A total of 531 Victory ships were built in between 1944 and 1946. VC2 design One of the first acts of the United States War Shipping Administration upon its formation in February 1942 was to commission the design of what came to be known as the Victory class. Initially designated EC2-S-AP1, where EC2 = Emergency Cargo, type 2 (Load Waterline Length between ), S = steam propulsion with AP1 = one aft propeller (EC2-S-C1 had been the designation of the Liberty ship design), it was changed to VC2-S-AP1 before the name "Victory Ship" was officially adopted on 28 Apr ...

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 ...
