A submerged signal ejector is a device used by submarines, similar to a torpedo tube. Although, instead of deploying weapons, it launches signal flares, smokes, distress buoys, SEPIRB, water temperature sensors and countermeasure decoys from the submarine. [1] [2] [3] [4] Signal ejectors can also send communication notes, [4] as was done in the rescuing of the BAP Pacocha (SS-48) crew. [5]
The Royal Navy (RN) is the naval warfare force of the United Kingdom, British Overseas Territories and Crown Dependencies, and a component of His Majesty's Naval Service. 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.
Sonar is a technique that uses sound propagation to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.
The Trafalgar class is a class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy, and the successor to the Swiftsure class. Like the majority of Royal Navy nuclear submarines, all seven boats were constructed at Barrow-in-Furness shipyard, Cumbria. With only one boat remaining active and in commission and six retired from the seven originally in service, the class makes up part of the Royal Navy's nuclear-powered ‘hunter-killer’ submarine force. The Trafalgar class has nearly been replaced by the larger and more capable Astute class, of which five are commissioned.
The Spearfish torpedo is the heavy torpedo used by the submarines of the Royal Navy. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface warfare (ASuW) capability. Spearfish development began in the 1970s, with production starting in 1988, and deployment in 1992. By 2004, the new weapon had completely replaced the older Tigerfish torpedo.
BAP Pacocha (SS-48) was a submarine of the Marina de Guerra del Perú named for the 1877 Battle of Pacocha, in which the Peruvian ironclad Huascar clashed with the Royal Navy. Formerly USS Atule (SS-403), a Balao-class submarine with a GUPPY IA upgrade, she had been sold to Peru and commissioned on 28 May 1974. She was rammed and sunk by a fishing trawler on 26 August 1988.
The Peruvian Navy is the branch of the Peruvian Armed Forces tasked with surveillance, patrol and defense on lakes, rivers and the Pacific Ocean up to 200 nautical miles from the Peruvian littoral. Additional missions include assistance in safeguarding internal security, conducting disaster relief operations and participating in international peacekeeping operations.
The Halifax-class frigate, also referred to as the City class, is a class of multi-role patrol frigates that have served the Royal Canadian Navy since 1992. The class is the outcome of the Canadian Patrol Frigate Project, which dates to the mid-1970s. HMCS Halifax was the first of an eventual twelve Canadian-designed and Canadian-built vessels which combine traditional anti-submarine capabilities with systems to deal with surface and air threats as well. Ships of the class are named after capital cities of Canadian provinces, the capital of Canada, Ottawa, and the major cities of Calgary, Montreal, and Vancouver.
The Mark 48 and its improved Advanced Capability (ADCAP) variant are American heavyweight submarine-launched torpedoes. They were designed to sink deep-diving nuclear-powered submarines and high-performance surface ships.
Future planning of the Royal Navy's capabilities is set through periodic Defence Reviews carried out by the British Government. The Royal Navy's role in the 2020s, and beyond, is outlined in the 2021 defence white paper, which was published on 22 March 2021. The white paper is one component of the Integrated Review of Security, Defence, Development and Foreign Policy, titled as Global Britain in a Competitive Age which was published on 16 March 2021.
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers.
The BAe Sea Eagle is a medium-weight sea-skimming anti-ship missile designed and built by BAe Dynamics. It is designed to sink or disable ships up to the size of aircraft carriers in the face of jamming and other countermeasures including decoys. Its users include the Royal Air Force and Royal Navy, the Royal Saudi Air Force, and the Indian Navy.
The Commander-in-Chief Fleet (CINCFLEET) was the admiral responsible for the operations of the ships, submarines and aircraft of the British Royal Navy from 1971 until April 2012. The post was subordinate to the First Sea Lord, the professional head of the Naval Service. In its last years, as the Navy shrank, more administrative responsibilities were added.
His Majesty's Naval Base, Clyde, primarily sited at Faslane on the Gare Loch, is one of three operating bases in the United Kingdom for the Royal Navy. It is the navy's headquarters in Scotland and is best known as the home of Britain's nuclear weapons, in the form of nuclear submarines armed with Trident missiles.
An acoustic torpedo is a torpedo that aims itself by listening for characteristic sounds of its target or by searching for it using sonar. Acoustic torpedoes are usually designed for medium-range use, and often fired from a submarine.
Anti-submarine warfare is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades.
BAP Abtao (SS-42) is an Abtao-class submarine of the Peruvian Navy. The vessel which was originally named BAP Tiburón ("Shark"), was constructed by the American Electric Boat company in the United States and launched in 1953. The Abtao class were the last submarines constructed by the United States for the export market. The submarine entered service in 1954 and by presidential decree, was renamed Abtao for the battle during the Chincha Islands War.
SS-48, SS 48 or SS48 may refer to:
The UMS Skeldar V-200 is a medium-range VTOL UAV developed by the Swedish aerospace company Saab. The Skeldar can be used for surveillance, intelligence gathering, light cargo transportation, and electronic warfare.
In 1989 the Royal Navy was under the direction of the Navy Department in the UK Ministry of Defence. It had two main commands, CINCFLEET and Naval Home Command.
