Sortie
A sortie (from the French word meaning ''exit'' or from Latin root ''surgere'' meaning to "rise up") is a deployment or dispatch of one military unit, be it an aircraft, ship, or troops, from a strongpoint. The term originated in siege warfare. In siege warfare In siege warfare, the word ''sortie'' refers specifically to a sudden sending of troops against the enemy from a defensive position—that is, an attack launched against the besiegers by the defenders. If the sortie is through a sally port, the verb ''to sally'' may be used interchangeably with ''to sortie''. Purposes of sorties include harassment of enemy troops, destruction of siege weaponry and engineering works, joining the relief force, etc. Sir John Thomas Jones, analyzing a number of sieges carried out during the Peninsular War (1807–1814), wrote: In aviation In military aviation Military aviation is the design, development and use of military aircraft and other flying machines for the purposes of ...

P 4-class Torpedo Boat
The P 4-class torpedo boat, Soviet designations Project 123-bis and Project 123-K, commonly called the Komsomolets class ( Russian: Комсомолец, a male member of the Komsomol), were Soviet aluminum-hulled torpedo boats. They were armed with twin heavy machine guns and two torpedoes. A large number of them were exported to allied states such as North Vietnam and China. They saw service in a variety of armed conflicts including World War II, the First Taiwan Strait Crisis, the Vietnam War and the Turkish Invasion of Cyprus. The P 4 torpedo boats consisted of two primary types; the Project 123-bis (B-123) type with machine guns, and the Project 123-K (K-123) type with added radar and machine guns. Design and development The P 4 torpedo boats were developed from the pre-war prototype Komsomolets torpedo boat (Project 123) in 1942 due to the unsatisfactory performance of the type motor torpedo boat. The original Project 123 was a single-step, hydroplaning design built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5"/54 Caliber Mark 42 Gun
The Mark 42 5"/54 caliber gun (127mm) is a naval gun (naval artillery) mount used by the United States Navy and other countries. It consists of the Mark 18 gun and Mark 42 gun mount. United States naval gun terminology indicates the gun fires a projectile in diameter, and the barrel is 54 Caliber (artillery), calibers long (barrel length is 5" × 54 = 270" or 6.9 meters.) In the 1950s, a gun with more range and a faster rate of fire than the 5"/38 caliber gun used in World War II was needed; therefore, the gun was created concurrently with the 3"/70 Mark 26 gun for different usages. The 5"/54 Mk 42 is an automatic, dual-purpose (air / surface target) gun mount. It is usually controlled remotely from the Mk 68 Gun Fire Control System, or locally from the mount at the One Man Control (OMC) station. The self-loading gun mount weighs about including two drums under the mount holding 40 rounds of Shell (projectile)#Separate loading cased charge, semi-fixed cas ...

P-15 Termit
The P-15 ''Termit'' (; ) is an anti-ship missile developed by the Soviet Union's Raduga design bureau in the 1950s. Its GRAU designation was 4K40, its NATO reporting name was ''Styx'' or SS-N-2. China acquired the design in 1958 and created at least four versions: the CSS-N-1 ''Scrubbrush'' and CSS-N-2 versions were developed for ship-launched operation, while the CSS-C-2 ''Silkworm'' and CSS-C-3 ''Seersucker'' were used for coastal defence. Other names for this basic type of missile include: HY-1, SY-1, and FL-1 ''Flying Dragon'' ( Chinese designations typically differ for export and domestic use, even for otherwise identical equipment), North Korean local produced KN-1 or KN-01, derived from both Silkworm variants and Russian & USSR P-15, Rubezh, P-20 P-22 . Despite its large size, thousands of P-15s were built and installed on many classes of ships from torpedo boats to destroyers, and coastal batteries and bomber aircraft (Chinese versions). Origins The P-15 was not the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-2 Terrier
The Convair RIM-2 Terrier was a two-stage medium-range naval surface-to-air missile (SAM), among the earliest SAMs to equip United States Navy ships. It underwent significant upgrades while in service, starting with beam-riding guidance with a range at a speed of Mach 1.8 and ending as a semi-active radar homing (SARH) system with a range of at speeds as high as Mach 3. It was replaced in service by the RIM-67 Standard ER (SM-1ER). Terrier has also been used as the base stage for a family of sounding rockets, beginning with the Terrier Malemute. History The Terrier was a development of the Bumblebee Project, the United States Navy's effort to develop a surface-to-air missile to provide a middle layer of defense against air attack (between carrier fighters and antiaircraft guns). It was test launched from on January 28, 1953, and first deployed operationally on the s, and , in the mid-1950s, with ''Canberra'' being the first to achieve operational status on Ju ...

Democratic Republic Of Vietnam
North Vietnam, officially the Democratic Republic of Vietnam (DRV; ; VNDCCH), was a country in Southeast Asia from 1945 to 1976, with sovereignty fully recognized in 1954.
