Picket Boat

picture info	Picket Boat A picket boat is a type of small naval craft. These are used for harbor patrol and other close inshore work, and have often been carried by larger warships as a ship's boat. They range in size between 30 and 55 feet. Patrol boats, or any craft engaged in sentinel duty, are sometimes referred to as picket boats, using " picket" in the generic sense, even if much larger than actual picket boats. United States The Union's long steam-powered Picket Boat Number One sank the Confederate ironclad '' Albemarle'' in 1864. (Although named "Picket Boat", this craft has also been called a steam launch). The boat was armed with a 12-pounder Dahlgren gun and a spar torpedo, of which the latter was employed in sinking ''Albemarle''. The Union's Potomac Flotilla also employed some picket boats. A number of American warships of the 19th century carried picket boats, such as the (her picket boat was heavily engaged by Spanish small-caliber shore fire during one incident in the Spanish–Americ ...

	QF 3-pounder Hotchkiss The QF 3-pounder Hotchkiss or in French use Canon Hotchkiss à tir rapide de 47 mm were a family of long-lived light naval guns introduced in 1886 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 32 to 50 calibers but 40 caliber was the most common version. They were widely used by the navies of a number of nations and often used by both sides in a conflict. They were also used ashore as coastal defense guns and later as an anti-aircraft gun, whether on improvised or specialized HA/LA mounts. Operational history French service The French Navy used two versions of the Hotchkiss 3-pounder: the short-barreled M1885 and the long-barreled M1902, which had a larger muzzle velocity than its predecessor. The French L/40 M1885 and the British QF 3-pounder were largely the same gun. Like the British who paired their 3-pounders with the larger QF 6-poun ...

picture info	Radar Picket A radar picket is a radar-equipped station, ship, submarine, aircraft, or vehicle used to increase the radar detection range around a nation or military (including naval) force to protect it from surprise attack, typically air attack, or from criminal activities such as smuggling. By definition a radar picket must be some distance removed from the anticipated targets to be capable of providing ''early warning''. Often several detached radar units would be placed to encircle a target to provide increased cover in all directions; another approach is to position units to form a ''barrier line''. Radar picket units may also be equipped to direct friendly aircraft to intercept any possible enemy. In British terminology the radar picket function is called aircraft direction. Airborne radar pickets are generally referred to as airborne early warning (AEW). In a sense radars intended to track ballistic missiles can be thought of as radar pickets, but because such systems are also used ...

picture info	Launch (boat) Launch is a name given to several different types of boat. The wide range of usage of the name extends from utilitarian craft through to pleasure boats built to a very high standard. In naval use, the launch was introduced as a ship's boat towards the end of the 17th century. On each warship, the launch was usually the largest boat out of those carried aboard. It could be propelled by oar or sail, with this type remaining in service into the 20th century. Steam launches were introduced on a trial basis in 1867, but as steam-powered ship's boats became more common, the majority were steam pinnaces. Other military examples were the various motor launches used in the 20th century, employed for harbour defence, anti-submarine patrols, escorting coastal convoys, minesweeping and recovering aircrew from crashed aircraft. Generally, these were decked boats, some of which were capable of fast speeds. A powered boat operated by a regulatory or official organisation may be termed a lau ...

picture info	Derfflinger-class Battlecruiser The class was a class of three battlecruisers (german: Schlachtkreuzer, links=no) of the Imperial German Navy. The ships were ordered for the 1912–13 Naval Building Program of the German Imperial Navy as a reply to the Royal Navy's two new s that had been launched a few years earlier. The preceding and the incrementally improved represented the end of the evolution of Germany's first generation of battlecruisers. The class had considerable improvements, including a larger primary armament, all of which was mounted on the centerline. The ships were also larger than the preceding classes. The class used a similar propulsion system, and as a result of the increased displacement were slightly slower. The class comprised three ships: , , and . All three of the ships saw active service with the High Seas Fleet during World War I. was commissioned shortly after the outbreak of war, and was present at most of the naval actions in the North Sea, including the battles of Dogger Ban ...

picture info	SMS Seydlitz Short Message/Messaging Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile devices exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines. SMS technology originated from radio telegraphy in radio memo pagers that used standardized phone protocols. These were defined in 1986 as part of the Global System for Mobile Communications (GSM) series of standards.GSM Doc 28/85 "Services and Facilities to be provided in the GSM System" rev2, June 1985 The first SMS message was sent on 3 December 1992, when Neil Papworth, a test engineer for Sema Group, sent "Merry Christmas" to the Orbitel 901 phone of colleague Richard Jarvis. SMS rolled out commercially on many cellular networks that decade and became hugely popular worldwide as a method of text communication. By the end of 2010, SMS w ...

picture info	Bayern-class Battleship The ''Bayern'' class was a class of four super-dreadnought battleships built by the German (Imperial Navy). The class comprised , , , and . Construction started on the ships shortly before World War I; ''Baden'' was laid down in 1913, ''Bayern'' and ''Sachsen'' followed in 1914, and ''Württemberg'', the final ship, was laid down in 1915. Only ''Baden'' and ''Bayern'' were completed, due to shipbuilding priorities changing as the war dragged on. It was determined that U-boats were more valuable to the war effort, and so work on new battleships was slowed and ultimately stopped altogether. As a result, ''Bayern'' and ''Baden'' were the last German battleships completed by the Kaiserliche Marine. ''Bayern'' and ''Baden'' were commissioned into the fleet in July 1916 and March 1917, respectively. This was too late for either ship to take part in the Battle of Jutland on 31 May and 1 June 1916. ''Bayern'' was assigned to the naval force that drove the Imperial Russian Navy from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	König-class Battleship The ''König'' class was a group of four dreadnought battleships built for the German (Imperial Navy) in the early 1910s. The class comprised , the lead ship, , , and . The design for the ships was derived from the preceding , using the same basic hull (watercraft), hull but with a rearranged main battery of ten guns in five twin-gun turrets to improve the guns' firing arcs. Instead of the staggered wing turrets used in the ''Kaiser''s, the ''König''s placed their main guns all on the centerline (nautical), centerline using superfire, superfiring pairs fore and aft. Budgetary constraints and the need to begin construction quickly to compete with Britain in the Anglo-German naval arms race prevented any more radical changes. Diesel engines were planned for the ships, but they could not be readied in time, so all four vessels reverted to steam turbines for their propulsion system. As tensions in Europe spiraled out of control during the July Crisis in 1914, work on the ships wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
