USS Olmsted (APA-188)
USS ''Olmsted'' (APA-188) was a that saw service with the US Navy for the task of transporting troops to and from combat areas. She was of the VC2-S-AP5 Victory ship design type. ''Olmsted'' was named for Olmsted County, Minnesota. World War II service ''Olmsted'' (''APA–188''), approved 16 March 1944, was laid down by Kaiser Shipbuilding Co., Vancouver, Washington, 11 April 1944, as MCV Hull no. 656; launched 4 July 1944; sponsored by Mrs. Duncan Gregg; accepted and commissioned 5 September 1944. Western Pacific operations On completion of shakedown 27 October 1944, ''Olmsted'' joined the U.S. Pacific Fleet. Transporting troops and supplies in support of amphibious operations, she spent the last year of the war in the Pacific Ocean with an itinerary that reads like a summary of the war's climactic stages: New Guinea, the Admiralties, Leyte, Lingayen Gulf, Okinawa and Japan. Apparently charmed, she was bombed at Luzon and again at Okinawa without damage. Twice b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olmsted County, Minnesota
Olmsted County is a county in the U.S. state of Minnesota. As of the 2020 census, the population is 162,847. Its county seat and most populous city is Rochester. Olmsted County is part of the Rochester Metropolitan Statistical Area. History The Wisconsin Territory was established by the federal government effective July 3, 1836, and existed until its eastern portion was granted statehood (as Wisconsin) in 1848. Therefore, the federal government set up the Minnesota Territory effective March 3, 1849. The newly organized territorial legislature created nine counties across the territory in October of that year. One of those original counties, Wabasha, had portions partitioned off in 1853 to create Fillmore and Rice counties. Then on February 20, 1855, portions of Rice, Wabasha, and Fillmore counties were partitioned off to create the present county, with Rochester (which was also platted that year) as county seat. The county name recognized David Olmsted (1822-1861), a member ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LCVP (United States)
The landing craft, vehicle, personnel (LCVP) or Higgins boat was a landing craft used extensively by the Allies of World War II, Allied forces in amphibious landings in World War II. Typically constructed from plywood, this shallow-draft, barge-like boat could ferry a roughly platoon-sized complement of 36 men to shore at 9 knot (unit), knots (17 km/h). Men generally entered the boat by climbing down a cargo net hung from the side of their troopship, troop transport; they exited by charging down the boat's lowered bow (ship), bow ramp. Designer Andrew Higgins based it on boats made for operating in swamps and marshes. More than 23,358 were built, by Higgins Industries and licensees.Herman, Arthur. ''Freedom's Forge: How American Business Produced Victory in World War II''.New York: Random House. . pp. 204-206. Taking the last letter of the LCVP designation, sailors often nicknamed the Higgins Boat the "Papa Boat" or "Peter Boat" to differentiate it from other landing craft ...

American Campaign Medal
The American Campaign Medal is a military award of the United States Armed Forces which was first created on November 6, 1942, by issued by President Franklin D. Roosevelt. The medal was intended to recognize those military members who had performed military service in the American Theater of Operations during World War II. A similar medal, known as the American Defense Service Medal was awarded for active duty service before the United States' entry into World War II. History The American Campaign Medal was established per Executive Order 9265,6 November 1942, by President Franklin D. Roosevelt and announced in War Department Bulletin 56, 1942. The criteria were initially announced in Department of the Army (DA) Circular 1, dated 1 January 1943, so that the ribbon could be authorized prior to design of the medal. The criteria for the medal were announced in DA Circular 84, dated 25 March 1948 and subsequently published in Army Regulation 600–65, dated 22 September 1948. The ...

Battle Of Okinawa
The , codenamed Operation Iceberg, was a major battle of the Pacific War fought on the island of Okinawa by United States Army (USA) and United States Marine Corps (USMC) forces against the Imperial Japanese Army (IJA). The initial invasion of Okinawa on 1 April 1945 was the largest amphibious assault in the Pacific Theater of World War II. The Kerama Islands surrounding Okinawa were preemptively captured on 26 March, (L-6) by the 77th Infantry Division. The 82-day battle lasted from 1 April until 22 June 1945. After a long campaign of island hopping, the Allies were planning to use Kadena Air Base on the large island of Okinawa as a base for Operation Downfall, the planned invasion of the Japanese home islands, away. The United States created the Tenth Army, a cross-branch force consisting of the U.S. Army 7th, 27th, 77th and 96th Infantry Divisions with the USMC 1st, 2nd, and 6th Marine Divisions, to fight on the island. The Tenth was unique in that it had its own Tact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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
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 based, subsurface ( 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 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 Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...

Bofors 40 Mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies and some Axis powers such as Nazi Germany and Hungary. In the pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...
