The Breguet Br.1150 Atlantic is a long-range maritime patrol aircraft designed and manufactured by French aircraft manufacturer Breguet Aviation. Designed in response to a 1958 NATO specification as a replacement for the Lockheed P2V Neptune, Breguet's submission was declared the winner over several competing bids. To produce the Atlantic, a multinational consortium, Société d'Étude et de Construction de Breguet Atlantic (SECBAT), was established. During 1963, an initial order for 60 Atlantics – 40 for France and 20 for Germany – was received. Follow-on orders from export customers followed shortly thereafter. It was first introduced to operational service during 1965. The Atlantic has been operated by a number of countries, commonly performing maritime roles such as reconnaissance and anti-submarine warfare. The Atlantic is also capable of carrying air-to-ground munitions to perform ground-attack missions; a small number of aircraft were also equipped to perform ELINT operations. An updated version, the Atlantique 2 or ATL2, was produced by Dassault Aviation for the French Navy in the 1980s. A further improved model, the Atlantique 3, was proposed during the 1990s but ultimately unbuilt. Other operators of the Atlantic have included the German Navy, the Italian Air Force, the Pakistan Navy, and the Royal Netherlands Navy. The Breguet Br.1150 Atlantic is a twin-engined, mid-winged monoplane with a "double-bubble" fuselage; the upper lobe comprising a pressurised crew compartment, and the lower lobe housing a 9 m (27 ft 6 in) long weapons bay, with sonobuoy tubes aft of the weapons bay. A radar scanner is housed in a retractable underfuselage radome, while a magnetic anomaly detector is housed in a tail boom. It is powered by a pair of Rolls-Royce Tyne turboprop engines. An all-aluminium structure is used throughout the Atlantic's airframe; corrosion is alleged to be a considerable problem due to environmental factors imposed by the maritime environment.
