HMS Duncan (D37)
HMS ''Duncan'' is the sixth and last of the Type 45 or ''Daring''-class air-defence destroyers built for the Royal Navy and launched in 2010. ''Duncan'' is named after Adam Duncan, 1st Viscount Duncan (1 July 1731 – 4 August 1804), who defeated the Dutch fleet at the Battle of Camperdown on 11 October 1797. The destroyer has served in the Mediterranean, Black, and Caribbean Seas, and in 2019 was deployed to the Persian Gulf in response to increased tensions with Iran in the region. In May 2024, she deployed to the Red Sea to protect international shipping from the ongoing Houthi attacks. Characteristics In 2014, the Royal Navy website stated that ''Duncan'' would be the first Type 45 destroyer to be armed with the Harpoon antiship missile system. On 2 March 2015, ''Duncan'' left Portsmouth armed with Harpoon antiship missiles. Construction ''Duncan''s construction began at the BAE Systems Naval Ships (now part of BAE Systems Surface Ships) yards at Govan and Scot ...

AHRS
An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information for aircraft, including roll, pitch, and yaw. These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes, accelerometers and magnetometers. They are designed to replace traditional mechanical gyroscopic flight instruments. The main difference between an Inertial measurement unit (IMU) and an AHRS is the addition of an on-board processing system in an AHRS, which provides attitude and heading information. This is in contrast to an IMU, which delivers sensor data to an additional device that computes attitude and heading. With sensor fusion, drift from the gyroscopes integration is compensated for by reference vectors, namely gravity, and the Earth's magnetic field. This results in a drift-free orientation, making an AHRS a more cost effective solutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AgustaWestland AW101
The AgustaWestland AW101 is a medium-lift helicopter in military and civil use. First flown in 1987, it was developed by a joint venture between Westland Helicopters in the United Kingdom and Agusta in Italy in response to national requirements for a modern naval utility helicopter. Several operators, including the armed forces of Britain, Denmark, and Portugal, use the name Merlin for their AW101 aircraft. It is manufactured at factories in Yeovil, England, and Vergiate, Italy. Licensed assembly work has also taken place in Japan and the United States. Prior to 2007, the aircraft had been marketed under the designation EH101. The original designation was EHI 01, from the name given to the Anglo-Italian joint venture—European Helicopter Industries—but a transcription error changed this to EH101. In 2000, Westland Helicopters and Agusta merged to form AgustaWestland, leading to the type's current designation. The AW101 entered into service in 1999 and has since replaced sev ...

Sea Venom (missile)
Sea Venom is an Anglo-French lightweight anti-ship missile developed by MBDA to equip the French Navy and the Royal Navy. The missile is known as ''Anti-Navire Léger'' (ANL) in France and Sea Venom (formerly "Future Anti-Surface Guided Weapon (Heavy)") in the United Kingdom. While initial operating capability had been expected with the Royal Navy in 2022, Sea Venom missiles were reported deployed with Royal Navy Wildcat helicopters operating as part of the Royal Navy's carrier strike group in 2021. The first test launch, from an AS365 Dauphin helicopter of the French DGA defence procurement agency, was successfully conducted on 21 June 2017.

Martlet (missile)
Martlet is a lightweight air-to-surface, surface-to-air, and surface-to-surface missile developed by Thales Air Defence for the United Kingdom. It is named after a mythical bird from English heraldry that never roosts, the martlet. Developed as the Lightweight Multirole Missile (LMM) to meet the UK's "Future Air-to-Surface Guided Weapon (Light)" requirement, the Ministry of Defence (MOD) placed an initial order for 1,000 missiles with deliveries due to start in 2013. However, initial operating capability was considerably delayed and took place in 2021 with full operating capability anticipated in 2024. The missile was given the name "Martlet" in British service. Development The Lightweight Multirole Missile was initially conceived as Thales' response to the MoD's Future Air-to-Surface Guided Weapon (Light) FASGW(L) requirement. It was designed to be launched from a variety of naval, air and land platforms against a wide range of targets. High precision reduces collateral damag ...

AgustaWestland AW159
The AgustaWestland AW159 Wildcat (previously called the Future Lynx and Lynx Wildcat) is a British military helicopter. It is an improved version of the Westland Super Lynx designed to serve in the battlefield utility, search and rescue and anti-surface warfare roles. In British service, common variants are being operated by both the Royal Navy and British Army, having replaced their Lynx Mk.7/8/9 predecessors. The AW159 has also been offered to several export customers, and has been ordered by the Republic of Korea Navy and the Philippine Navy. Development Background In 1995, the British Government announced that the Royal Navy's existing Westland Lynx helicopters were to be replaced; at that point, the service was intended to operate an all- Merlin fleet. Despite this stated intent, Westland Helicopters continued to hold talks with the Ministry of Defence (MOD) to find a future role for the type during the late 1990s; the firm issued multiple proposals to either extend the l ...

Naval Decoy IDS300
Naval Decoy IDS300 (Inflatable Decoy System) is a passive, off-board, octahedral, corner reflector decoy of the Royal Navy's Type 45 destroyer and the US Navy's destroyer, forming part of a layered defence to counter anti-ship missiles. Unlike chaff, the decoy is persistent and will float for up to three hours in sea state 4. Jane's was first to report the United Kingdom was looking for a new floating decoy as part of a program known as the Naval Passive Off-Board Decoy (N-POD), on March 3, 2019. In US Navy service, it is designated as the Mk 59 decoy launching system. The system is made by Irvin Aerospace Ltd, Hertfordshire in the United Kingdom. Deployment The decoy is launched out of a deck-mounted tube and self-inflates on the sea surface before being released to free-float past the stern to mimic a ship's radar and radio signatures. The deployment and inflation process takes seconds and the decoy is completely independent, requiring no further input from the ship. Typica ...
