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. Development In 1958, NATO produced a specification for a long-range maritime patrol aircraft to replace the Lockheed P2V Neptune, with Breguet's design, the Br 1150, chosen as the winner of the competition at the end of the year. A multinational consortium, Société d'Étude et de Construction de Breguet Atlantic (SECBAT) was set up to develop and build the Atlantic. The first prototype made its maiden flight at Toulouse on 21 October 1961, with the second prototype flying on 25 February 1962, followed by two preproduction aircraft with a longer fuselage in February 1963 and September 1964. An initial order for 60 Atlantics 40 for France and 20 for Germany was placed in 1963, with deliveries starting in 1965 and continuing to 1968. The production line had shut down by the time the Netherlands placed an order for nine Atlantics and Italy ordered eighteen. Aircraft from this second production batch were delivered from 1972 to 1974. In 1978, the French Government authorised development of a new, updated version of the Atlantic, the Atlantic Nouvelle Génération (later known as the Atlantique 2 when orders from other nations did not occur). While the airframe and engines of the new aircraft changed little, equipment and
