Link 11
TADIL-A/Link 11 is a secure half-duplex tactical data link used by NATO to exchange digital data. It was originally developed by a joint committee including members from the Canadian Navy, US Navy and Royal Navy to pass accurate targeting information between ships. The final standard was signed in Ottawa in November 1957, where the British proposed the name "TIDE" for "Tactical International Data Exchange". It was later made part of the NATO STANAG standardization process. The system operates on two frequencies, one in the high frequency (HF) range for over-the-horizon (OTH) communications, and another in the ultra high frequency (UHF) range that uses much smaller antennas and is suitable for smaller ships but lacks the OTH performance. The system broadcasts packets of 30 bits length, with 6 bits of error correction and 24 bits of payload data. The payload is encrypted. Link 14 was adopted at the same time as a low-end counterpart to Link 11. Link 14 is essentially a digital te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HQ-9
The HQ-9 () is a long-range semi-active radar homing (SARH) surface-to-air missile (SAM) developed by the People's Republic of China. The naval variant is the HHQ-9 (). Description The HQ-9 is a derivative of the Russian S-300. Justin Bronk describes the missile as a "hybrid design based on a Russian SA-20 but with radar, seeker head and C2 elements heavily influenced by American and Israeli technology." Early HQ-9s may use track-via-missile guidance developed from a United States MIM-104 Patriot missile purchased from Israel or Germany. According to a 2001 article from ''Defence International'', the HQ-9 is 6.8 m. long with a mass of nearly two tons. The diameters of the first and second stages are 700 mm and 560 mm, respectively. The warhead mass is 180 kg, and the maximum speed is Mach 4.2. The HQ-9 may use fire-control radars from other Chinese SAM systems.

People's Liberation Army Navy
The People's Liberation Army Navy (PLAN; ), also known as the People's Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People's Liberation Army. The PLAN traces its lineage to naval units fighting during the Chinese Civil War and was established on 23 April 1949. Throughout the 1950s and early 1960s, the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology. Until the late 1980s, the PLAN was largely a riverine and littoral force ( brown-water navy). In the 1990s, following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy, the leaders of the Chinese military were freed from worrying overland border disputes. Traditionally subordinated to the PLA Ground Force, PLAN leaders were now able to advocate for a renewed attention towards the seas. Chinese military officials have outlined plans to operate in the first and second island chains, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helipad
A helipad is a landing area or platform for helicopters and powered lift aircraft. While helicopters and powered lift aircraft are able to operate on a variety of relatively flat surfaces, a fabricated helipad provides a clearly marked hard surface away from obstacles where such aircraft can land safely. Larger helipads, intended for use by helicopters and other vertical take-off and landing aircraft (VTOL), may be called ''vertiports.'' An example is Vertiport Chicago, which opened in 2015. Usage Helipads may be located at a heliport or airport where fuel, air traffic control and service facilities for aircraft are available. Most helipads are located remote from populated areas due to sounds, winds, space and cost constraints. However, some skyscrapers maintain a helipad on their roofs in order to accommodate air taxi services. Some basic helipads are built on top of highrise buildings for evacuation in case of a major fire outbreak. Major police departments may use a ...

Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their glider. After completing design and construction of the '' Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while they waited for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a " nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a surface ship, or anot ...

Type 79 100 Mm Naval Gun
{{unreferenced, date=April 2009 The Type 79 Twin 100 mm gun is the first indigenously developed large caliber Chinese naval gun. A decision was made in 1970 to replace the Soviet 100/56 Bu-34 single 100 mm semi-enclosed gun mount. By June 1973, the first batch was completed and two were installed onboard frigates for test and evaluation. Two more upgrades were eventually developed. Type 79 The first of the family, this gun was fully automatic and controlled by Type 343 radar. However, being the first fully automatic gun and the first indigenously developed gun at the same time, the Chinese was not confident enough on the design, and thus incorporated manual backup systems. This proved to be baseless because later operation proved that the reliability of the automated system was just as good as the simpler manual system. Type 79A Based on the successful performance of the automated system, the manual backup system was eliminated in this upgrade. As a result, the ...

Anti-ship Missile
An anti-ship missile (AShM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea skimming variety, and many use a combination of inertial guidance and active radar homing. A good number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the '' Fritz X'', including the Italian battleship ''Roma'' and the light cruiser .
