Boston Navy Yard
The Boston Navy Yard, originally called the Charlestown Navy Yard and later Boston Naval Shipyard, was one of the oldest shipbuilding facilities in the United States Navy. It was established in 1801 as part of the recent establishment of the new United States Department of the Navy, U.S. Department of the Navy in 1798. After 175 years of military service, it was decommissioned as a naval installation on 1 July 1974. The property is administered by the National Park Service, becoming part of Boston National Historical Park. Enough of the yard remains in operation to support the moored USS Constitution, USS ''Constitution'' ("Old Ironsides") of 1797, built as one of the Original six frigates of the United States Navy, original six heavy frigates for the revived American navy, and the oldest warship still commissioned in the United States Navy and afloat in the world. , a 1943 World War II-era Fletcher-class destroyer, ''Fletcher''-class destroyer serving as a museum ship, ...

Helipad
A helipad is a landing area or platform for helicopters and powered lift aircraft. While helicopters and powered lift aircraft are able to operate on a variety of relatively flat surfaces, a fabricated helipad provides a clearly marked hard surface away from obstacles where such aircraft can land safely. Larger helipads, intended for use by helicopters and other vertical take-off and landing aircraft (VTOL), may be called ''vertiports.'' An example is Vertiport Chicago, which opened in 2015. Usage Helipads may be located at a heliport or airport where fuel, air traffic control and service facilities for aircraft are available. Most helipads are located remote from populated areas due to sounds, winds, space and cost constraints. However, some skyscrapers maintain a helipad on their roofs in order to accommodate air taxi services. Some basic helipads are built on top of highrise buildings for evacuation in case of a major fire outbreak. Major police departments may use a d ...

Talbot County-class Tank Landing Ships
Talbot was an automobile marque introduced in 1902 by English-French company Clément-Talbot. The founders, Charles Chetwynd-Talbot, 20th Earl of Shrewsbury and Adolphe Clément-Bayard, reduced their financial interests in their Clément-Talbot business during the First World War. Soon after the end of the war, Clément-Talbot was brought into a combine named STD Motors. Shortly afterward, STD Motors' French products were renamed Talbot instead of Darracq. In the mid-1930s, with the collapse of STD Motors, Rootes bought the London Talbot factory and Antonio Lago bought the Paris Talbot factory, Lago producing vehicles under the marques Talbot and Talbot-Lago. Rootes renamed Clément-Talbot Sunbeam-Talbot in 1938, and stopped using the brand name Talbot in the mid-1950s. The Paris factory closed a few years later. Ownership of the marque came by a series of takeovers to Peugeot, which revived use of the Talbot name from 1978 until 1994. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Tallahatchie County (LST-1154)
USS ''Tallahatchie County'' (LST-1154) was the second of only two ''Talbot County''-class tank landing ships (LSTs) built for the United States Navy just after World War II. Named after Tallahatchie County, Mississippi, she was the only U.S. Navy vessel to bear the name. Construction LST-1154 was laid down on 4 August 1945 at the Boston Navy Yard; launched on 19 July 1946; sponsored by Mrs. Wilder D. Baker; and commissioned on 24 May 1949. She recommissioned as an AVB in 1962. History From her commissioning until 1962, LST-1154 alternated assignments for the Amphibious Force, Atlantic Fleet along the east coast of the United States with assignment to the 6th Fleet during periodic deployments to the Mediterranean. She was redesignated USS ''Tallahatchie County'' (LST-1154) on 1 July 1955. She was decommissioned at Charleston (SC) Naval Shipyard in 1960 in preparation for conversion to AVB-2.

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tank Landing Ship
Landing Ship, Tank (LST), or tank landing ship, is the naval designation for ships first developed during World War II (1939–1945) to support amphibious operations by carrying tanks, vehicles, cargo, and landing troops directly onto shore with no dock (maritime), docks or piers. This enabled amphibious assaults on almost any beach. The LST had a highly specialized design that enabled ocean crossings as well as shore groundings. The bow (ship), bow had a large door that could open, deploy a ramp and unload vehicles. The LST had a Flat-bottomed boat, flat keel that allowed the ship to be beaching (nautical), beached and stay upright. The twin propellers and rudders had protection from ship grounding, grounding. The LSTs served across the globe during World War II including in the Pacific War and in the European theatre of World War II, European theatre. The first tank-landing ships were built to British requirements by converting existing ships; the UK and the US then collaborat ...

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 ...

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] |
5"/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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
