The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.
Cordite is a family of smokeless propellants developed and produced in the United Kingdom since 1889 to replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the barrel of the gun.
The River class was a class of 151 frigates launched between 1941 and 1944 for use as anti-submarine convoy escorts in the North Atlantic. The majority served with the Royal Navy (RN) and Royal Canadian Navy (RCN), with some serving in the other Allied navies: the Royal Australian Navy (RAN), the Free French Navy (FFN), the Royal Netherlands Navy and, post-war, the South African Navy (SAN).
HMS Bramham (L51) was a Hunt-class destroyer of the Royal Navy laid down in Alexander Stephen and Sons shipyards Govan, Scotland on 7 April 1941. She was launched on 29 January 1942 and commissioned into the Royal Navy on 16 June 1942. She was named after the Bramham Moor Hunt and has been the only Royal Navy warship to bear the name. She was adopted by the town of Beverley in the East Riding of Yorkshire during the Warship Week savings campaign of 1942.
A replenishment oiler or replenishment tanker is a naval auxiliary ship with fuel tanks and dry cargo holds which can supply both fuel and dry stores during underway replenishment (UNREP) at sea. Many countries have used replenishment oilers.
Ships of the Royal Navy is a naval history reference work by J. J. Colledge (1908–1997); it provides brief entries on all recorded ships in commission in the Royal Navy from the 15th century, giving location of constructions, date of launch, tonnage, specification and fate.
James Joseph Colledge was a British naval historian, author of Ships of the Royal Navy, the standard work on the fighting ships of the Royal Navy from the 15th century to the 20th century.
An Explosive ROF was a UK Government-owned Royal Ordnance Factory (ROF), which specialised in manufacturing explosives during and after World War II. Note: In World War I, the name used in the UK for Government-owned explosives factories was National Explosives Factory; and the Cordite factory at Gretna was known as HM Factory, Gretna.
Seafield is a coastal strip situated on the Firth of Forth between Leith and Portobello in north-east Edinburgh, Scotland. The area is mainly commercial, and has little housing.
The Astraea class was an eight ship class of protected cruisers built for the Royal Navy during the 1890s. The ships served on a number of foreign stations during their careers, particularly in the waters of the Indian and Pacific Oceans, and around the Cape of Good Hope. Already obsolete by the outbreak of the First World War, most continued to see service in a variety of roles, though rarely in a front line capacity. By the end of the war the majority were being used as training or depot ships, and they were soon sold out of the service and scrapped. However one ship, HMS Hermione, was bought by the Marine Society and used as a training ship until 1940.
The Harpoon is an all-weather, over-the-horizon, anti-ship missile developed and manufactured by McDonnell Douglas. The AGM-84E Standoff Land Attack Missile (SLAM) and later AGM-84H/K SLAM-ER are cruise missile variants.
The Battle of Lake Pontchartrain was a single-ship action on September 10, 1779, part of the Anglo-Spanish War. It was fought between the British sloop-of-war HMS West Florida and the Continental Navy schooner USS Morris in the waters of Lake Pontchartrain, then in the British province of West Florida.
Lieutenant is a commissioned officer rank in many nations' navies and coast guards. It is typically the most senior of junior officer ranks. In most navies, the rank's insignia may consist of two medium gold braid stripes, the uppermost stripe featuring an executive curl in many Commonwealth of Nations; or three stripes of equal or unequal width.
HMS Godetia was the second Flower-class corvette with that name built for the Royal Navy. She served during the Second World War as part of the Section Belge of the Royal Navy (RNSB). With the liberation of Belgium in late 1944, the vessel was returned to the United Kingdom. In common with other Flower-class corvettes, the ship was named after an eponymous flower.
The following index is provided as an overview of and topical guide to Wikipedia's articles on recreational dive sites. The level of coverage may vary:
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
