USS Epping Forest (LSD-4)
USS ''Epping Forest'' (LSD-4/MCS-7) was an acquired by the U.S. Navy during World War II for duty in the Pacific Theater. Her task was to carry and land amphibious landing craft and other equipment and to recover and repair landing craft when possible. Named for an estate in Lancaster County, Virginia where Mary Ball Washington, mother of George Washington (first President of the United States), was born, she was the only U.S. Naval vessel to bear the name. Originally authorized as USS ''Epping Forest'' (APM-4), a mechanized artillery transport, the ship was reclassified as dock landing ship USS ''Epping Forest'' (LSD-4) on 1 July 1941; laid down 23 November 1942 at the Moore Drydock Company of Oakland, California; launched 2 April 1943; sponsored by Mrs. J. H. Heintz; and commissioned 11 October 1943. Onboard aircraft capability Aircraft (still in commission in late 1940s or early 1950s) were fitted/retro-fitted with a prefabricated steel grated "Portable Deck" suspende ...

Antiaircraft
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 airc ...

Hawaiian Islands
The Hawaiian Islands ( haw, Nā Mokupuni o Hawai‘i) are an archipelago of eight major islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some from the island of Hawaii in the south to northernmost Kure Atoll. Formerly the group was known to Europeans and Americans as the Sandwich Islands, a name that James Cook chose in honor of the 4th Earl of Sandwich, the then First Lord of the Admiralty. Cook came across the islands by chance when crossing the Pacific Ocean on his Third Voyage in 1778, on board HMS ''Resolution''; he was later killed on the islands on a return visit. The contemporary name of the islands, dating from the 1840s, is derived from the name of the largest island, Hawaii Island. Hawaii sits on the Pacific Plate and is the only U.S. state that is not geographically connected to North America. It is part of the Polynesia subregion of Oceania. The state of Hawaii occupies the archipelago almost in its entirety (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia ...

Landing Craft Utility
A Landing Craft Utility (LCU) is a type of boat used by amphibious forces to transport equipment and troops to the shore. They are capable of transporting tracked or wheeled vehicles and troops from amphibious assault ships to beachheads or piers. Colombia The Golfo de Tribugá-class landing craft is an LCU developed by COTECMAR for the Colombian National Navy. The vessel class is also known as BDA ( es, Buque de Desembarco Anfibio) and an unarmored version for logistical and humanitarian services has also been developed, known as BALC ( es, Buque de Apoyo Logístico y Cabotaje). Operators *: 5 in service, 1 on order *: 1 in service *: 2 in service France The Engin de débarquement amphibie rapide (EDA-R) landing catamaran or L-CAT, entered service in January 2011.

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most ...

I-beam
An I-beam, also known as H-beam (for universal column, UC), w-beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double-T (especially in Polish, Bulgarian, Spanish, Italian and German), is a beam with an or -shaped cross-section. The horizontal elements of the are flanges, and the vertical element is the "web". I-beams are usually made of structural steel and are used in construction and civil engineering. The web resists shear forces, while the flanges resist most of the bending moment experienced by the beam. The Euler–Bernoulli beam equation shows that the I-shaped section is a very efficient form for carrying both bending and shear loads in the plane of the web. On the other hand, the cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred. History The method of producing an I-beam, as rolled from a single piece of wrought iron, wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
