PT Boat
A PT boat (short for patrol torpedo boat) was a motor torpedo boat used by the United States Navy in World War II. It was small, fast, and inexpensive to build, and it was valued for its maneuverability and speed. However, PT boats were hampered at the beginning of the war by ineffective torpedoes, limited armament, and comparatively fragile construction that limited some of the variants to coastal waters. In the US Navy they were organized in Motor Torpedo Boat Squadrons (MTBRONs). The PT boat was very different from the first generation of torpedo boats, which had been developed at the end of the 19th century and featured a displacement hull form. These first generation torpedo boats rode low in the water, displaced up to 300 tons, and had a top speed of . During World War I Italy, the US, and UK developed the first high-performance, gasoline-powered motor torpedo boats (often with top speeds over ) and corresponding torpedo tactics, but these projects were all quickly di ...

Patrol Torpedo Boat Q-111 Luzon
''Q-111 Luzon'' was a motor torpedo boat of the United States Army during World War II as part of the Offshore Patrol based at Manila. History In 1935, the Commonwealth Government passed the National Defense Act. The Act was criticized because it did not include funding for a Commonwealth navy instead relying on the United States Asiatic Fleet. Determined to develop an indigenous naval defense, the government authorized the creation of its own naval patrol unit consisting of a squadron of three wooden-hull, fast patrol torpedo boats with the goal to reach 36 boats by 1946. To avoid overlap with the Asiatic Fleet, the unit was to be part of a new seagoing arm of the Philippine Army under the United States Army Forces in the Far East. On 9 February 1939, the Off Shore Patrol (OSP) was formed with its headquarters located at Muelle Del Codo, in the Port of Manila and was headed by U.S. Naval Academy graduate First Lieutenant Jose V. Andrada (namesake of the Jose Andrada-class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Motor Boat
Coastal Motor Boat was a small high-speed British torpedo boat used by the Royal Navy in the First World War and up to end of the Second World War. During the First World War, following a suggestion from three junior officers of the Harwich destroyer force that small motor boats carrying a torpedo might be capable of travelling over the protective minefields and attacking ships of the Imperial German Navy at anchor in their bases, the Admiralty gave tentative approval to the idea and, in the summer of 1915, produced a Staff Requirement requesting designs for a Coastal Motor Boat for service in the North Sea. These boats were expected to have a high speed, making use of the lightweight and powerful petrol engines then available. The speed of the boat when fully loaded was to be at least and sufficient fuel was to be carried to give a considerable radius of action. They were to be armed in a variety of ways, with torpedoes, depth charges or for laying mines. Secondary arma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whitehead Mark 5 Torpedo
The Whitehead Mark 5 torpedo was a Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role in 1910. The Mark 5 was the first torpedo to be manufactured by a foreign company, the Whitehead facility in the United Kingdom, and in 1908, by the Naval Torpedo Station in Newport, Rhode Island. It was also the first torpedo to allow the firing ship to vary the torpedo's speed and range. Characteristics The Mark 5 was a "hot-running" (powered by heated air) torpedo, as opposed to previous Whitehead designs, which were "cold-running". It was similar in performance to the Bliss-Leavitt torpedoes of that era. Around 500 units were produced by the Naval Torpedo Station and Vickers Limited. The Mark 5 had variable speed; at a high speed of 40 knots, it had a range of 1000 yards. A low speed of 27 knots allowed the weapon a range of 4000 yards; at medium speed of 36 knots, its range was 2000 yards. This variable speed was set before loading the torpedo in its ...

Josephus Daniels
Josephus Daniels (May 18, 1862 – January 15, 1948) was a newspaper editor, Secretary of the Navy under President Woodrow Wilson, and U.S. Ambassador to Mexico under President Franklin D. Roosevelt. He managed ''The News & Observer'' in Raleigh, at the time North Carolina's largest circulation newspaper, from the 1890s until his death. Daniels was a vehement white supremacist and segregationist; he and his newspaper "championed the white supremacy cause in frequent news reports, vigorously worded editorials, provocative letters, and vicious front page cartoons that called attention to what the newspaper called the horrors of 'negro rule.'" Along with Charles Brantley Aycock and Furnifold McLendel Simmons, he was a leading perpetrator of the Wilmington insurrection of 1898, in which white mobs overthrew the legitimately elected biracial government in Wilmington, expelled black and white political leaders from the city, destroyed the property and businesses of black citiz ...

Hickman Sea Sled
The Hickman Sea Sled is an inverted vee planing hull invented by Albert Hickman. The Sea Sled is a direct forerunner of the modern high speed catamaran or tunnel hull. The reduced friction is due to a "trapped" gas film between the hull surface and water. A similar effect is seen in super-cavitating torpedoes where a gas generator creates a film separation to water friction.

Bureau Of Construction And Repair
The Bureau of Construction and Repair (BuC&R) was the part of the United States Navy which from 1862 to 1940 was responsible for supervising the design, construction, conversion, procurement, maintenance, and repair of ships and other craft for the Navy. The bureau also managed shipyards, repair facilities, laboratories, and shore stations. On 20 June 1940, Congress passed a law which consolidated the Bureau's functions with those of the Bureau of Engineering (BuEng), creating the Bureau of Ships (BuShips). History The Bureau was staffed by officers of the Construction Corps (called constructors) with advanced degrees in naval architecture. Six civilian constructors were hired by the Navy in 1794 to supervise construction of the frigates authorized by Congress that year.Snyder, Philip W., RADM USN "Bring Back the Corps" ''United States Naval Institute Proceedings'' February 1979 p.49 The Bureau of Construction, Equipment, and Repairs was established in 1842 as one of the five ori ...

David W
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and '' Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; pag ...

Marine Engine
An inboard motor is a marine propulsion system for boats. As opposed to an outboard motor, where an engine is mounted outside the hull of the craft, an inboard motor is an engine enclosed within the hull of the boat, usually connected to a propulsion screw by a driveshaft. Marine diesel engines used in international shipping are the largest, most powerful engines ever produced. History The first marine craft to utilize inboard motors were steam engines going back to 1805 and the ''Clermont'' and the '' Charlotte Dundas''. Harbour tugs, and small steam launches had inboard steam engines. In the 1880s the naphtha engine made its appearance and a few boat engines appeared. Such engines had low power and high fuel consumption. The gasoline (petrol) engine pioneer Gottlieb Daimler and Maybach built a four-cycle boat engine and tested it in 1887 on the Neckar River. Sintz in America built several commercially available engines from 1893. Sizes Inboard motors may be of sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
