HM Armed Smack Inverlyon
His Majesty's or HM Armed Smack ''Inverlyon'' was a fishing smack that was converted to a Q-ship during the First World War. Q-ships served as decoys to lure German submarines near enough so that concealed weapons could be brought to bear and sink the submarines. On 15 August 1915, ''Inverlyon'' succeeded in luring German submarine within range and sinking her with nine shots from her gun. The Royal Navy Gunner in command of the vessel, Ernest Martin Jehan, received the Distinguished Service Cross and members of ''Inverlyon''s crew shared the bounty offered for German submarines. After ''Inverlyon''s Q-ship career ended, she returned to fishing, but was sunk by on 1 February 1917. Career ''Inverlyon'' was a fishing smack of 59 tons burthen that was a part of the fishing fleet at Lowestoft on the Suffolk coast. The wooden boat had a flush deck, two masts, and no engine. ''Inverlyon''s sails were fore-and-aft rigged and may have been red ochre in colour, the traditional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lieutenant
A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a commissioned officer rank in the armed forces of many nations. The meaning of lieutenant differs in different militaries (see comparative military ranks), but it is often subdivided into senior (first lieutenant) and junior (second lieutenant and even third lieutenant) ranks. In navies, it is often equivalent to the army rank of captain; it may also indicate a particular post rather than a rank. The rank is also used in fire services, emergency medical services, security services and police forces. Lieutenant may also appear as part of a title used in various other organisations with a codified command structure. It often designates someone who is " second-in-command", and as such, may precede the name of the rank directly above it. For example, a "lieutenant master" is likely to be second-in-command to the "master" in an organisation using both ranks. Political uses include lieutenant governor in various g ...

Messenger Pigeon
The homing pigeon, also called the mail pigeon or messenger pigeon, is a variety of domestic pigeons (''Columba livia domestica'') derived from the wild rock dove, selectively bred for its ability to find its way home over extremely long distances. The rock dove has an innate homing ability, meaning that it will generally return to its nest using magnetoreception. Flights as long as have been recorded by birds in competitive pigeon racing. Their average flying speed over moderate distances is around and speeds of up to have been observed in top racers for short distances. In 2019 after sixty years a new world record was set in Netherlands for the fastest racing pigeon flight, distance flown 239 kilometers at speed above 143 kilometers per hour. Because of this skill, domesticated pigeons were used to carry messages as messenger pigeons. They are usually referred to as "pigeon post" if used in post service, or "war pigeon" during wars. Until the introduction of telephones, ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point-blank Range
Point-blank range is any distance over which a certain firearm can hit a target without the need to compensate for bullet drop, and can be adjusted over a wide range of distances by sighting in the firearm. If the bullet leaves the barrel parallel to the sight, the bullet, like any object in flight, is pulled downwards by gravity, so for distant targets, the shooter must point the firearm above the target to compensate. But if the target is close enough, bullet drop will be negligible so the shooter can aim the gun straight at the target. If the sights are set so that the barrel has a small upward tilt, the bullet starts by rising and later drops. This results in a weapon that hits too low for very close targets, too high for intermediate targets, too low for very far targets, and point blank at two distances in between. For a .270 Winchester, as an example, the bullet first crosses the line of sight at about 23 metres (25 yards) as it is rising and has a maximum impact above th ...

White Ensign
The White Ensign, at one time called the St George's Ensign due to the simultaneous existence of a cross-less version of the flag, is an ensign worn on British Royal Navy ships and shore establishments. It consists of a red St George's Cross on a white field, identical to the flag of England except with the Union Flag in the upper canton. The White Ensign is also worn by yachts of members of the Royal Yacht Squadron and by ships of Trinity House escorting the reigning monarch. In addition to the United Kingdom, several other nations have variants of the White Ensign with their own national flags in the canton, with the St George's Cross sometimes being replaced by a naval badge omitting the cross altogether. Yachts of the Royal Irish Yacht Club wear a white ensign with an Irish tricolour in the first quadrant and defaced by the crowned harp from the Heraldic Badge of Ireland. The Flag of the British Antarctic Territory and the Commissioners' flag of the Northern Lighthouse Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield just enough personnel and devices for navigation during battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oberleutnant Zur See
''Oberleutnant zur See'' (''OLt zS'' or ''OLZS'' in the German Navy, ''Oblt.z.S.'' in the ''Kriegsmarine'') is traditionally the highest rank of Lieutenant in the German Navy. It is grouped as OF-1 in NATO. The rank was introduced in the Imperial German Navy by renaming the former rank of ''Premier Lieutenant'' in 1890. Within the navy officers of this rank were simply addressed as ''Herr Oberleutnant''. To distinguish naval officers from those of the army, the suffix ''zur See'' (at sea) was added in official communications, sometimes shortened to ''z.S.'' (''Oblt.z.S.''). The rank has since been used by the ''Reichsmarine'', ''Kriegsmarine'', and ''Bundesmarine''. In the ''Volksmarine'' the rank was originally used in the same way until the suffix ''zur See'' was dropped. In the ''Kriegsmarine'' engineers (''Ingenieur – Ing.'') of the same rank were distinguished as ''Oberleutnant (Ing.)''.

East-northeast
The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography. A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and northwest—each located halfway between two cardinal directions. Some disciplines such as meteorology and navigation further divide the compass with additional azimuths. Within European tradition, a fully defined compass has 32 'points' (and any finer subdivisions are described in fractions of points). Compass points are valuable in that they allow a user to refer to a specific azimuth in a colloquial fashion, without having to compute or remember degrees. Designations The names of the compass point directions follow these rules: 8-wind compass rose * The four cardinal directions are north (N), east (E), s ...

Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...
