Tsugaru-class Patrol Vessel
The is a class of PLH type patrol vessels of the Japan Coast Guard (JCG; former Maritime Safety Agency, MSA). Backgrounds In late 1970s, it was clear that the new international rules on exclusive economic zone would need a considerable increase in the size of the Maritime Safety Agency fleets. In order to cover a wide ocean with a small number of vessels, JMSA began considering the shipping operation of air-sea rescue helicopters. At first, ''Sōya'' was built as a prototype in the plan of FY1977. Then, from the supplementary budget for the same year, construction of this class was started. Design This class is roughly based on its prototype, ''Sōya'', it is the same as having a long forecastle, but her icebreaking capability was omitted. In order to operate helicopter with these small ships, antiroll tanks and fixed fin stabilizers were set up. Since this class were built for a long time, the design are slightly different. In particular, the overall improvement was add ...

Ensign Of The Japanese Coast Guard
An ensign is the national flag flown on a vessel to indicate nationality. The ensign is the largest flag, generally flown at the stern (rear) of the ship while in port. The naval ensign (also known as war ensign), used on warships, may be different from the civil ensign (merchant ships) or the yacht ensign (recreational boats). Large versions of naval ensigns called battle ensigns are used when a warship goes into battle. The ensign differs from the jack, which is flown from a jackstaff at the bow of a vessel. In its widest sense, an ensign is just a flag or other standard. The European military rank of ensign, once responsible for bearing a unit's standard (whether national or regimental), derives from it (in the cavalry, the equivalent rank was cornet, named after a type of flag). Ensigns, such as the ancient Roman ensigns in the Arch of Constantine, are not always flags. National ensigns In nautical use, the ensign is flown on a ship or boat to indicate its organizat ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communicat ...

Piracy In The Strait Of Malacca
Piracy in the Strait of Malacca has long been a threat to ship owners and the mariners who ply the 900 km-long (550 miles) sea lane. In recent years, coordinated patrols by Indonesia, Malaysia, Thailand, and Singapore along with increased security on vessels have sparked a sharp downturn in piracy. The Strait of Malacca's geography makes the region very susceptible to piracy. It was and still is an important passageway between China and India, used heavily for commercial trade. The strait is on the route between Europe, the Suez Canal, the oil-exporting countries of the Persian Gulf, and the busy ports of East Asia. It is narrow, contains thousands of islets, and is an outlet for many rivers, making it ideal for pirates to evade capture. History Piracy in the Strait of Malacca was not only a lucrative way of life but also an important political tool. Rulers relied on the region's pirates to maintain control. For example, it was through the loyalty of Orang Laut pirate ...

Forward Operating Base
A forward operating base (FOB) is any secured forward operational level military position, commonly a military base, that is used to support strategic goals and tactical objectives. A FOB may or may not contain an airfield, hospital, machine shop, or other logistical facilities. The base may be used for an extended period of time. FOBs are traditionally supported by main operating bases that are required to provide backup support to them. A FOB also improves reaction time to local areas as opposed to having all troops on the main operating base. Description In its most basic form, a FOB consists of a ring of barbed wire around a position with a fortified entry control point, or ECP. More advanced FOBs include an assembly of berms, concrete barriers, gates, watchtowers, bunkers and other force protection infrastructure. They are often built from Hesco bastions. FOBs will also have an Entry Control Point (ECP). An ECP is a controlled entry and exit point of the FOB and will typical ...

Search And Rescue
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs; urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water. International Search and Rescue Advisory Group (INSARAG) is a UN organization that promotes the exchange of information between national urban search and rescue organizations. The duty to render assistance is covered by Article 98 of the UNCLOS. Definitions There are many different definitions of search and rescue, depending on the agency involved and country in question. *Canadian Forces: "Search and Rescue comprises the search for, and provision of aid to, persons, ships or other craft which are, or are fear ...

Sikorsky S-76
The Sikorsky S-76 is a medium-size commercial utility helicopter designed and produced by the American helicopter manufacturer Sikorsky Aircraft. It is the company's first helicopter specifically developed for the civilian market. The S-76 was developed during the mid-1970s, originally begin designated ''S-74'' but renamed in honor of the U.S. Bicentennial. Drawing upon its recently-developed S-70 helicopter, it features twin turboshaft engines, four-bladed main and tail rotors, and retractable landing gear. On , the prototype performed its maiden flight. The initial production variant was the S-76A, the first deliveries of which took place on . Several improved models were produced over time, including the S-76 Mk II launched in 1982, and the S-76B in 1987. Development of the S-76D was particularly troubled, being delayed by four years of delays due to flight envelope issues; it was finally certified for operation on . The S-76 initially encountered strong demand from the ...

Shipboard Helicopter Operations
Shipboard helicopter operations is the use of techniques which allows operation of rotary wing aircraft from naval vessels. In the case of military vessels the operations also include tactics and associated weapons and troops. Landing a helicopter on the flight deck of what is sometimes a small ship in heavy seas presents the pilot with a challenges that include: deck movement, turbulent airflows, and using control systems that were not necessarily designed for the marine environment. Flight operations of shipboard helicopter operations include preparing the aircraft and crew for the mission, cargo and ordnance handling (for armed helicopters), passenger supervision, aircraft departure, communications with the ship during the mission and recovery. Apart from the more routine passenger and cargo transportation missions, shipboard helicopter operations are used by civilian and military operators to conduct search and rescue missions, while what for the civilian operators is of ...

Remote Weapon Station
A remote controlled weapon station (RCWS), or remote weapon station (RWS), also known as a remote weapon system (RWS), is a remotely operated weaponized system often equipped with fire-control system for light and medium-caliber weapons which can be installed on a ground combat vehicle or sea- and air-based combat platforms. Such equipment is used on modern military vehicles, as it allows a gunner to remain in the relative protection of the vehicle. It may also be retrofitted onto existing vehicles; for example, the Crows system is being fitted to American Humvees.

Rotary Cannon
A rotary cannon, rotary autocannon, rotary gun or Gatling cannon, is any large- caliber multiple-barreled automatic firearm that uses a Gatling-type rotating barrel assembly to deliver a sustained saturational direct fire at much greater rates of fire than single-barreled autocannons of the same caliber. The loading, firing and ejection functions are performed simultaneously in different barrels as the whole assembly rotates, and the rotation also permits the barrels some time to cool. The rotating barrels on nearly all modern Gatling-type guns are powered by an external force such as an electric motor, although internally powered gas-operated versions have also been developed. The cyclic multi-barrel design synchronizes the firing/reloading sequence. Each barrel fires a single cartridge when it reaches a certain position in the rotation, after which the spent casing is ejected at a different position and then a new round is loaded at another position. During the cycle, t ...
