Hecla-class Survey Vessel
The ''Hecla'' class formed the backbone of the Royal Navy's ocean survey fleet from the mid-1960s. Design The hull design was based on that of the RRS ''Discovery'' and the Hecla class were built to commercial standards costing £1.25 million each. They carried two small survey craft, a launch, a Land Rover and a Wasp helicopter, for which there was a flight deck and hangar. They were chiefly funded from the Polaris Submarine Ballistic Nuclear Missile programme, with their major task to carry out regular oceanographic observations essential for the Polaris submarines to hide in thermal layers. Special modifications Besides the strengthened hull for work in ice and the provision of air conditioning necessary for work in all climates, they had modifications particular for a scientific vessel: wet and dry laboratories; a survey chartroom and photographic darkroom; oceanographic winches for deep seawater analysis and coring; stabilisers and a bow thruster, which enabled the ship ...

Hydra-class Sloop
The ''Hydra'' class were a class of three paddlewheel steam sloops of the British Royal Navy. They saw active service variously in the Baltic during the Crimean War, against Ottoman forces in Syria and against slavers in West Africa. Latterly ''Hydra'' and ''Hecate'' were used for survey in the Mediterranean, the Pacific, Australia and the Atlantic, and thus their names were re-used for the s in the late 20th century. Two of the class were broken up after more than twenty-five years of service, and ''Hecla'' was sold for commercial use in 1863. Design The ships were designed by Sir William Symonds and were approved on 3 November 1837. They were built of wood, displaced 1,096 tons and had a length on the gundeck of . Propulsion Power was provided by a two-cylinder side-lever steam engine driving paddle wheels. In ''Hecla'' and ''Hecate'' this engine was provided by Scott & Sinclair, and was rated at 240 nominal horsepower; in ''Hydra'' the steam engine was provided by Boulton an ...

Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rockall
Rockall () is an uninhabitable granite islet situated in the North Atlantic Ocean. The United Kingdom claims that Rockall lies within its exclusive economic zone (EEZ) and is part of its territory, but this claim is not recognised by Ireland. It and the nearby skerries of Hasselwood Rock and Helen's Reef are the only emergent parts of the Rockall Plateau. The rock was formed by magmatism as part of the North Atlantic Igneous Province during the Paleogene. Rockall's approximate distances from the closest islands in each direction are as follows: It is west of Soay, Scotland; northwest of Tory Island, Ireland; and south of Iceland. The nearest permanently inhabited place is North Uist, an island in the Outer Hebrides of Scotland, to the east. The United Kingdom claimed Rockall in 1955 and incorporated it as a part of Scotland in 1972. The UK does not make a claim to extended EEZ based on Rockall, as it has ratified the United Nations Convention on the Law of the Sea (UNCLOS ...

Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing correct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft h ...
