Encyclopedia > Patrol bomber

A patrol bomber, or patrol aircraft, is an airplane designed to operate for long times over water in an anti-shipping or anti-submarine role. Fixed-wing aircraft is a term used to refer to what are more commonly known as aeroplanes in Commonwealth English (excluding Canada) or airplanes in North American English. ... Shipping is the transport of cargo between seaports by ships, typically large steel vessels powered by diesel engines or steam turbine plants. ... USS Los Angeles A submarine is a specialized watercraft that can operate underwater. ...

Many of the original patrol aircraft were converted from long-range bombers or airliners, with notable conversions being Germany's Focke-Wulf Condor and the widespread use of B-24 Liberators during World War II to patrol the areas between Iceland and Greenland and attack German submarines. Purpose-built aircraft were also used, including England's Shorts Sunderland and the American-made PBY Catalina. A bomber is a military aircraft designed to attack ground targets, primarily by dropping bombs. ... An airliner is a large fixed-wing aircraft (an aeroplane/airplane) initially designed for the transport of paying passengers, and usually operated by an airline company (which owns or leases the aircraft). ... The Focke-Wulf Fw 200 was a four engine airliner. ... Royal Canadian Air Force B-24 Liberator The Consolidated B-24 Liberator was produced in greater numbers than any other American combat aircraft, and was used by most of the Allied air forces in World War II. Designed as a heavy bomber, it served with distinction not only in that... World War II was a truly global conflict with many facets: Immense human sacrifice, fierce indoctrinations, and the use of new, extremely devastating weapons - the atom bomb being the ultimate. ...

The Sunderland, S.25, was a flying boat patrol bomber, developed for the Royal Air Force by Short Brothers, based on their successful S.23 Empire flying boats, the flagship of Imperial Airways. ... The PBY Catalina (aka PBY Canso) was the definitive air-sea rescue aircraft of the 1930s and 1940s. ...

After the war the patrol role was generally taken over by conversions of civilian airliners that had range and performance better than most WWII bombers. The latest jet-powered bombers of the 1950s did not have the endurance needed for long, over-water cruising, and more importantly did not have the low loitering speed necessary for anti-submarine operations. The main threat to the United States throughout the 1960s and into the 1980s were Soviet submarines, which were found primarily with the use of sonobuoys, and then attacked with homing torpedoes. // Events and trends The 1950s in Western society was marked with a sharp rise in the economy for the first time in almost 30 years and return to the 1920s-type consumer society built on credit and boom-times, as well as the height of the baby-boom from returning...

A modern torpedo, historically called a self propelled torpedo, is a self-propelled guided projectile that (after being launched above or below the water surface) operates underwater and is designed to detonate on contact or in proximity to a target. ...

Today the threat of a large scale submarine attack is remote, and many forces are downsizing their patrol aircraft fleets. Those still in service are used primarily for counter-smuggling and Exclusive Economic Zone enforcement duties. In international maritime law, an Exclusive Economic Zone (EEZ) is a seazone extending from a states coast over which the state has special rights over the exploration and use of marine resources. ...


Maritime patrol aircraft are typically fitted with a wide range of sensors:

  • Radar to detect surface shipping movements;
  • Magnetic Anomaly Detector (MAD) to detect submarine movements. The MAD is typically mounted on an extension from the tail of the aircraft in order to minimize the aircraft's magnetic field interference towards the MAD;
  • Sonobuoy dropped from the aircraft onto the sea to detect submarine movements, then transmit the data back to the aircraft;
  • ELINT sensors to monitor civilian and military telecommunications;
  • Infrared camera, as well as old-fashioned search light, are also useful in monitoring shipping movements.

A maritime patrol aircraft typically carries a dozen or so crew members, including relief flight crews, in order to effectively operate all the equipments for up to 12 hours at a time. This long range radar antenna (approximately 40m (130ft) in diameter) rotates on a track to observe activities near the horizon. ... A magnetic anomaly detector (MAD) is a piece of equipment that is used to detect minute variations in the Earths magnetic field. ... A sonobuoy is a buoy with a sonar attached to it. ... ELINT stands for ELectronic INTelligence, and refers to intelligence-gathering by use of electronic sensors. ...
