Ocean escortOcean escort was a type of United States Navy warship. They were an evolution of the World War II destroyer escort types. The ocean escorts were intended as convoy escorts and were designed for mobilization production in wartime or low-cost mass production in peacetime. They were commissioned from 1954 through 1974, serving in the Cold War and the Vietnam War. The ocean escorts' hull classification symbol was DE, a carryover from the World War II era when vessels of similar size and role were classified as destroyer escorts.
Limbo (weapon)Limbo, or Anti Submarine Mortar Mark 10 (A/S Mk.10), was the final development of the forward-throwing anti-submarine weapon Squid, designed during the Second World War and was developed by the Admiralty Underwater Weapons Establishment in the 1950s. Limbo was installed on the quarterdeck of Royal Navy escort ships from 1955 to the mid-1980s, Australian-built destroyer and s. Limbo was widely employed by the Royal Canadian Navy, being incorporated into all destroyer designs from the late 1950s to the early 1970s, including the , , , and classes and the Type 12 President Class frigates built for the South African Navy in the 1960s.
Underway replenishmentReplenishment at sea (RAS) (North Atlantic Treaty Organization/Commonwealth of Nations) or underway replenishment (UNREP) (U.S. Navy) is a method of transferring fuel, munitions, and stores from one ship to another while under way. First developed in the early 20th century, it was used extensively by the United States Navy as a logistics support technique in the Pacific theatre of World War II, permitting U.S. carrier task forces to remain at sea indefinitely.
Radar picketA radar picket is a radar-equipped station, ship, submarine, aircraft, or vehicle used to increase the radar detection range around a nation or military (including naval) force to protect it from surprise attack, typically air attack, or from criminal activities such as smuggling. By definition a radar picket must be some distance removed from the anticipated targets to be capable of providing early warning. Often several detached radar units would be placed in a ring to encircle a target to provide increased cover in all directions; another approach is to position units to form a barrier line.
Destroyer leaderDestroyer leader (DL) was the United States Navy designation for large destroyers from 9 February 1951 through the early years of the Cold War. United States ships with hull classification symbol DL were officially frigates from 1 January 1955 until 1975. The smaller destroyer leaders were reclassified as destroyers and the larger as cruisers by the United States Navy 1975 ship reclassification so destroyer escorts could be reclassified as frigates (FF) in conformance with international usage of the term.
RazeeA razee or razée rəˈziː is a sailing ship that has been cut down (razeed) to reduce the number of decks. The word is derived from the French vaisseau rasé, meaning a razed (in the sense of shaved down) ship. During the transition from galleons to more frigate-like warships (1600 – 1650) there was a general awareness that the reduction in topweight afforded by the removal of upperworks made ships better sailers; Rear Admiral Sir William Symonds noted after the launch of Sovereign of the Seas that she was "cut down" and made a safe and fast ship.
Brown-water navyThe term 'brown-water navy or 'riverine navy refers in its broadest sense to any naval force capable of military operations in littoral zone waters. The term originated in the United States Navy during the American Civil War, when it referred to Union forces patrolling the muddy Mississippi River, and has since been used to describe the small gunboats and patrol boats commonly used in rivers, along with the larger "mother ships" that supported them.
Pennant numberIn the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of pendant number, which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship.
Royal Netherlands NavyThe Royal Netherlands Navy (Koninklijke Marine) is the naval force of the Kingdom of the Netherlands. It is one of the four Netherlands Armed Forces. It was founded on 8 January 1488, making it the third oldest naval force in the world. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers.
Squadron (naval)A squadron, or naval squadron, is a significant group of warships which is nonetheless considered too small to be designated a fleet. A squadron is typically a part of a fleet. Between different navies there are no clear defining parameters to distinguish a squadron from a fleet (or from a flotilla), and the size and strength of a naval squadron varies greatly according to the country and time period. Groups of small warships, or small groups of major warships, might instead be designated flotillas by some navies according to their terminology.
