Breguet Br.1050 Alizé
France’s Carrier Submarine Hunter

France’s carrier-borne submarine hunter flew from Clemenceau and Foch for four decades, fought for India in 1961 and 1971, saw out the century over Kosovo and retired only when the Foch left the fleet in 2000.

The Story

The Alizé: how Breguet turned a failed strike jet into France’s carrier submarine hunter

The Alizé was born from a cancellation. Breguet’s Br.960 Vultur had been a naval strike aircraft with a turboprop in the nose and a small jet in the tail, and when it was abandoned the French Navy asked for an anti-submarine aircraft built on the same, well-liked airframe. Breguet took out the rear jet and put a retractable radar dome in its place, installed a Rolls-Royce Dart turboprop up front, made room for a third crew member and set nacelles into the wing leading edges to hold sonobuoys and the main wheels. The first of three prototypes flew in October 1956, but early trials revealed poor handling and a long period of changes followed.

Catapult and deck-landing trials began on shore installations in 1957 and moved to the British carrier HMS Eagle in March 1958, since France’s own new carriers were still being built. An order for 100 was cut to 75 for the Aéronavale, and final assembly took place at Biarritz. The first production Alizé was handed over in 1959 and the type went to sea with Flottilles 4F, 6F and 9F, first from the light carrier Arromanches and then from the new Clemenceau and Foch. A crew of three, pilot, navigator and radar operator, worked as a hunter-killer team, finding a submarine with radar and buoys and attacking with a homing torpedo or depth charges carried in the internal bay.

India bought twelve new aircraft and later two ex-French ones for its light carrier INS Vikrant, and Indian Alizés flew in the Goa operation of 1961 and the 1971 war with Pakistan, when one was shot down by a Pakistani F-104 Starfighter, the type’s best-known combat loss. In France the Alizé was upgraded again and again, gaining a new Iguane radar in the 1980s, but by the 1990s it could no longer chase modern nuclear submarines and turned to surface surveillance. It flew from the Foch during the Kosovo air campaign of 1999, and its career ended in September 2000 with the carrier’s retirement.

01The Alizé in Indian service: Goa, 1965 and the 1971 war

The Indian Navy’s Alizés equipped INAS 310, the squadron known as the Cobras, and were delivered from 1961. They operated from shore bases and from the light carrier INS Vikrant. Their first operation came almost at once: in December 1961 they flew maritime patrol and photographic reconnaissance during India’s seizure of Portuguese Goa. During the 1965 war with Pakistan they flew patrols off the west coast but saw no combat.

The 1971 war was different. Vikrant sailed into the Bay of Bengal with Sea Hawk fighter-bombers and Alizés, and the Alizés flew anti-submarine and surface patrols for the carrier group. One Alizé was shot down by a Pakistan Air Force F-104 Starfighter. The type’s numbers dwindled in the 1980s, and when Vikrant was rebuilt to operate Sea Harriers in 1987 the Alizés moved ashore. India retired them in 1991, replacing them with anti-submarine helicopters, and one is preserved at the Naval Aviation Museum in Goa.

02The Alizé’s last decade: from submarine hunter to surface watcher

The French Navy never had the money to replace its Alizés with a new carrier anti-submarine aircraft, so it kept upgrading them. In the mid-1960s thirty were modified to fire the US Mk 44 torpedo and the wire-guided AS.12 missile. In the early 1980s 28 were rebuilt to the ALM (Alizé Modernisé) standard with a Thomson-CSF Iguane pulse-compression radar, OMEGA navigation, new sonobuoy receivers, chaff and flare dispensers and a new radar-warning system. In the 1990s more were fitted with decoys, a new autopilot and avionics, and in 1996 and 1997 some received the Chlio infrared camera.

By then the Alizé could not realistically hunt nuclear submarines, and it became the eyes of the carrier group, watching surface shipping off Lebanon in the 1980s and later in the Persian Gulf. It flew from the Foch during NATO’s Kosovo campaign in spring 1999. The last carrier landing came on 27 June 2000, and the type was withdrawn on 15 September 2000 as the Foch was sold to Brazil. Airborne surveillance for the French carrier passed to the E-2C Hawkeye aboard the new Charles de Gaulle.


Design & Engineering

What makes the Alizé special

01

A radar that drops out of the belly

Where the Vultur had a jet engine in its tail, the Alizé had its radar. The antenna sat in a retractable dome in the rear fuselage, lowered in flight for searching and pulled back in for take-off and carrier landing. Early aircraft used the DRAA-2A radar; the 1980s ALM upgrade fitted the Thomson-CSF DRAA-10A Iguane, a pulse-compression set that could detect a ship at long range and, sea state permitting, a periscope at around 25 nautical miles. A radar-warning receiver gave the crew a first electronic-surveillance capability.

02

Sonobuoys in the wings

The Alizé’s wing carried two pods set into the leading edges. Their rear sections took the main undercarriage, which retracted forwards, and their front sections held sonobuoys on release racks. The navigator, seated beside the pilot, doubled as acoustic operator, listening to the buoys and using the Julie explosive-echo tactic to fix a submarine’s position. The radar operator sat behind them. With radar, buoys and a weapons bay in one airframe, a single Alizé could search, localise and attack.

03

A small aircraft for small carriers

The Alizé was sized for the carriers France actually had. With a wingspan of 15.6 m and wings that folded upwards, it fitted the lifts and hangars of the Arromanches and later the larger Clemenceau and Foch, and it was light enough at about 8.2 tonnes for their catapults. Its single Dart turboprop drove a four-bladed propeller, used water-methanol injection for extra take-off power and gave useful residual jet thrust. Pilots found it underpowered high up, where the margin above stalling speed shrank to a few tens of knots.

03The Alizé’s weapons and crew stations

The internal bay under the fuselage was designed for a single homing torpedo, first the French L4 and later the American Mk 44 and Mk 46, or for depth charges; it could also take rescue containers or an extra 500-litre fuel tank. Underwing pylons carried depth charges, bombs, 68 mm rocket pods or two AS.12 wire-guided missiles for attacking surfaced submarines and small craft. Sonobuoys rode in the wing pods.

The crew sat in a short glazed cabin. The pilot was in front on the left, the navigator in front on the right handling navigation and acoustics, and the radar and sensor operator sat behind them. A fourth seat or a passenger could be fitted in the rear. The main undercarriage had twin wheels on each leg to spread the loads of carrier landings, and a yoke-type arrester hook was mounted under the rear fuselage.

  • ALH: 1990s standard with decoys, new autopilot and, on some aircraft, Chlio infrared sensor.
05The Alizé’s operating costs: a long-lived economy

The Alizé was cheap by carrier-aviation standards: one engine, three crew and a small airframe. Its longevity was itself a cost decision, since France chose repeated upgrades over buying a new carrier anti-submarine aircraft. Against that, a turboprop working from salt-laden decks needed constant corrosion control, and the airframes accumulated very high hours; French sources commonly give a total of around 330,000 flying hours for the fleet. No per-hour figure has been published.

Stories & Eyewitnesses

Stories & eyewitnesses: the Alizé at sea

Development

A strike jet turned inside out

The Alizé kept the Vultur’s wing and lost its tail jet.

Read the full story
Breguet’s Br.960 Vultur had been designed as a carrier attack aircraft with a turboprop for cruise and a jet in the tail for a dash. When the Navy dropped it, the airframe’s handling was good enough that Breguet was asked to build an anti-submarine aircraft from it. The second Vultur prototype was modified as a demonstrator with a fixed radar under the fuselage and wing nacelles. It proved a poor test aircraft, difficult to fly and with very limited performance, but it showed the layout could work, and the real Alizé followed with a Dart engine and a radar where the jet had been.
Trials

Learning to land on a British deck

France’s new carrier aircraft first went to sea on HMS Eagle.

Read the full story
When the Alizé was ready for carrier trials, the new French carriers Clemenceau and Foch were still under construction. After catapult launches and arrested landings on shore installations in 1957, the trials moved to the Royal Navy’s big carrier HMS Eagle in March 1958. The flight tests had already shown that the prototype’s handling was poor, and a long period of modification separated first flight from service. The third prototype introduced the more powerful engine that went into production, and the first aircraft reached the Aéronavale in 1959.
Combat

Over Goa, December 1961

The Indian Navy’s newest aircraft flew in its first operation within a year of arrival.

Read the full story
India’s Alizés had only just been commissioned with INAS 310 when the government moved against Portuguese Goa in December 1961. The Alizés flew maritime patrol and photographic reconnaissance in support of the operation, watching the sea approaches for Portuguese warships. The operation was over within days. For the Indian Navy’s young air arm it was a first taste of operational flying, and the same squadron would take the Alizé to war again a decade later.
Combat

The 1971 war and the F-104

Vikrant’s Alizés flew the carrier’s patrols, and one did not come home.

Read the full story
In December 1971 INS Vikrant operated in the Bay of Bengal during the war that created Bangladesh, its air group made up of Sea Hawks and Alizés. The Alizés flew anti-submarine and surface patrols around the carrier group. The submarine threat was real: Pakistan’s submarine Ghazi was lost off Visakhapatnam early in the war, reportedly while hunting Vikrant. During the war an Indian Alizé was shot down by a Pakistan Air Force F-104 Starfighter, the type’s best-known combat loss. Vikrant’s Alizés went on flying from the carrier until it was rebuilt for Sea Harriers in 1987.

3,156 hours: a navigator’s life on the Alizé

Bruno Boudet’s notebooks record 542 carrier landings.

Read the full story
Bruno Boudet joined the French Navy in 1975 and flew first on the Atlantic maritime patrol aircraft. In September 1980 he was posted to Flottille 6F, which had been flying the Alizé since 1959, because, as he put it, he had joined naval aviation and wanted to taste life aboard a carrier. He stayed as navigator, tactical officer and instructor, logging 3,156 hours on the Alizé and 542 carrier landings. His memoirs, built from his flight logs and photographs, describe a career spent less on aeroplanes than on crews.
Upgrade

Iguane: a new radar for an old aeroplane

The 1980s ALM rebuild kept the Alizé useful for another 20 years.

Read the full story
Rather than buy a new aircraft, the French Navy rebuilt 28 Alizés in the early 1980s to the ALM standard. The heart of it was the Thomson-CSF Iguane radar, a pulse-compression set related to the one later fitted to the Atlantique 2, able to detect ships at long range and a periscope at around 25 nautical miles in suitable seas. OMEGA navigation, new sonobuoy receivers, chaff and flare dispensers under the wing and a new radar-warning receiver came with it. With the Navy’s mission shifting from submarines to surface ships, the Alizé became an early stand-in for an airborne surveillance aircraft.
Combat

Kosovo from the Foch

In 1999 the Alizé flew its last war.

Read the full story
When NATO began its air campaign against Yugoslavia in spring 1999, the French carrier Foch sailed into the Adriatic with its air group, Alizés included. By then the oldest Alizés were about 40 years old and had long since given up front-line submarine hunting. Their job was surface surveillance, building a picture of shipping around the carrier group. It was the type’s last operational deployment, and a remarkable final act for an aircraft first flown in 1956.
Retirement

27 June 2000: the last trap

The Alizé left the fleet with the carrier that had carried it.

Read the full story
The final carrier landing by a Breguet Alizé took place aboard the Foch on 27 June 2000. The type was formally withdrawn on 15 September 2000, as the Foch was sold to Brazil and the French Navy waited for its nuclear carrier Charles de Gaulle and the E-2C Hawkeye. In just over four decades, French sources credit the fleet with about 330,000 flying hours. Flottille 6F, which had operated the Alizé since 1959, was among the units that flew it to the end.
Survivor

Number 5 at Toulouse

An early Alizé, never upgraded, is being restored by Ailes Anciennes.

Read the full story
Alizé serial number 5 entered service with the Aéronavale in 1959 and flew with Escadrille 2S and Flottilles 4F and 6F until it was retired in 1977. Because it was never modernised, it represents the type in its original form. It then spent more than 30 years as a gate guardian at the naval air station at Nîmes before the volunteers of Ailes Anciennes Toulouse retrieved it in early 2012. Long years outdoors had left it badly corroded, and restoration began with the port wing and undercarriage.
Survivor

F-AZYI: the Alizé that still flies

Number 59 is the type’s only airworthy example.

Read the full story
Alizé number 59 was restored to flying condition in France under the civil registration F-AZYI and is commonly described as the only airworthy example left. It has appeared at airshows including the La Ferté-Alais meeting. Others are preserved in museums, among them the Musée de l’Air et de l’Espace at Le Bourget, the naval aviation museum at Rochefort, Savigny-lès-Beaune, Lyon-Corbas and Montélimar, and in India at the Naval Aviation Museum in Goa, a reminder that the type’s longest war record was written by Indian crews.
