The Breguet Br.1050 Alizé (French: "Tradewind") was a French carrier-based anti-submarine warfare aircraft. It was developed in the 1950s, based loosely on the prototype Breguet Vultur attack aircraft.

[edit] Description

The Alizé was a low-wing monoplane of conventional configuration. It had a CSF radar system with a retractable antenna dome in its belly. The cockpit accommodated a crew of three, including pilot, radar operator, and sensor operator. The pilot was seated in front on the right, the radar operator in front on the left, and the sensor operator sat sideways behind them. The landing gear was of tricycle configuration, with the main gear retracting backwards into nacelles in the wings. The main gear had dual wheels, and the front part of the nacelles accommodated sonobuoys. The Alizé had a yoke-style arresting hook.

The internal weapons bay could accommodate a homing torpedo or depth charges, and underwing stores pylons could carry bombs, depth charges, rockets, or missiles. Typical underwing stores included 68 millimeter rocket pods or AS.12 wire-guided antiship missiles.


[edit] Operational history

A total of 89 examples of the Alizé were built between 1957 and 1962, including two preproduction prototypes. Seventy-five production aircraft were acquired by the Aéronavale, with initial service delivery in March 1959. The Alizé went into operation on the carriers Arromanches, Clémenceau and Foch, and were also used in shore-based training. 12 were acquired by the Indian Navy. Some sources say that there were five preproduction prototypes, which may mean some of the prototypes were brought up to production standard and passed on to the Aéronavale; and that India acquired 17 examples, which hints that they bought five used aircraft from the Aéronavale.

The Indian Navy operated the Alizé from shore bases and from the light carrier INS Vikrant. The Alizé was used for reconnaissance and patrol during India's 1961 invasion of Portuguese Goa, and was also used for ASW patrol during the Indo-Pakistani War of 1971, during which one Alizé was shot down by a Pakistan Air Force F-104 Starfighter. It was also instrumental in taking out many gunboats unopposed during the war. The Alizé dwindled in numbers in the Indian Navy during the 1980s, was relegated to shore-based patrol in 1987, and was finally phased out in 1991, replaced in its duties by ASW helicopters.

The Aéronavale provided the Alizé with a series of upgrades. A modernization program performed in the early 1980s refitted 28 of the aircraft to the Br.1050M standard, featuring improved Thomson-CSF Iguane radar as used on the Atlantique NG ocean-patrol aircraft, new OMEGA radio navigation gear, and a new ARAR 12 radar and radio location ("electronic support measures / ESM") system.

Another upgrade program in the early 1990s fitted 24 of these aircraft with a new decoy system; a microcomputer-based data processing system that could have hardly been imagined when the aircraft was new; a datalink system; and other new avionics. Later in the decade, they were also fitted with the Thomson-CSF TTD Optronique Chlio forward-looking infrared (FLIR) imaging sensor. Despite the upgrades, by this time the Alize was clearly not up to the task of hunting modern nuclear submarines, and so it was tasked with ocean surface patrol.

As late as 1997, the Aéronavale was still operating 24 examples for surface patrol, though they were clearly on their way out by then. The Alizé was used operationally during the NATO air campaign against Federal Republic of Yugoslavia over Kosovo in the spring of 1999, with the aircraft flying off the carrier Foch. The last Alizé was finally withdrawn from service in 2000 with the retirement of the Foch.
