The Breguet 19 was designed as a successor to a highly successful World War I Breguet 14 bomber. Initially, it was to be powered by a 340 kW (450 hp) Bugatti U-16 engine, driving a four-blade propeller, and a prototype was shown on the 7th Paris Air Show in November 1921 with this engine. [1] A revised design was flown in March 1922 with a single 340 kW (450 hp) Renault 12Kb inline engine. After trials, the Breguet 19 was ordered by the French Army 's Aéronautique Militaire in September 1923.

Mass production, both for the Aéronautique Militaire and export, began in France in 1924.

Design

The Breguet 19 was a sesquiplane in which the lower wing was substantially smaller than the upper wing, with a conventional layout and braced wings. The fuselage was ellipsoid in cross-section and built up from a frame of duralumin pipes. Breguet made extensive use of duralumin as a construction material which resulted in an unusually light structure for its size, instead of steel or wood. It was faster than other bombers, and even many fighter aircraft which resulted in widespread interest which was further increased by successful record flights. The forward fuselage was covered with duralumin sheets, while the tail, rear fuselage and wings were covered with linen. It had a conventional fixed landing gear with a tail skid. The crew of two, pilot and observer/bombardier, sat in tandem in open cockpits and were provided with dual controls.

A wide variety of engine types were fitted, mostly water-cooled V-12 or W-12 inline engines, including the following:

A fixed 7.7 mm (0.303 in) Vickers machine gun with an interrupter gear was operated by the pilot, while the observer had twin 7.7 mm (0.303 in) Lewis Guns on a gun ring. There was also a fourth machine gun, which could be fired by the observer downwards through an opening in the floor. The Br.19CN2 night fighter variant was fitted with two fixed forward-firing machine guns. [2] The bomber could carry up to 472 kg (1,041 lb) of bombs under the fuselage, or small bombs up to 50 kg (110 lb) vertically in an internal bomb bay. The reconnaissance variant could carry 12 x 10 kg (22 lb) bombs. The reconnaissance variant had a camera mounting, which was optional on the bomber variant. All variants were equipped radio.

Operational history

The Breguet 19 had its baptism of fire in the Spanish Civil War where it was the mainstay of the Spanish Republican Air Force's (the Government's) bomber fleet.

Greece

In the Greco-Italian War which took place during World War II, 18 Breguets were operational at the outbreak of war, with 1 Observation (or Army Cooperation) Mira, under I Corp Command, based at Perigiali, near Corinth and with 2 Observation Mira under II Corps command, based at Larissa and Kozani. [3] On 4 November 1940, a Royal Hellenic Air Force Breguet from 2 Mira was sent looking for the attacking 3rd Julia Alpine Division, locating it in a mountain pass near Metsovo. Three more Breguets sent to bomb the Italian division were in turn attacked by three Fiat CR.42 fighters. A Breguet was shot down, one crash-landed and the third returned to base, badly damaged. [4]

Br.19 A.2
Two-seat reconnaissance aircraft.
Br.19 B.2
Two-seat light bomber biplane. These first two variants were the most numerous, and were practically identical. They used a variety of engines, the most popular being the 300 kW (400 hp) Lorraine-Dietrich 12Db, the 340 kW (450 hp) Lorraine-Dietrich 12Eb, the Renault 12K, the Hispano-Suiza 12H and the Farman 12We. [2]
Br.19 CN.2
Night fighter version, almost identical to the B2 reconnaissance variant with two additional forward-firing machine guns. [2]
Br.19 GR
(Grand Raid) A variant specially modified for long-distance flights, after early long-range attempts were made with the regular Br.19 A2 no.23 fitted with additional fuel tanks. The first Br.19 GR (no.64) had a fuel tank of about 2,000 L (440 imp gal; 530 US gal) and captured the world distance record in 1925.
Br.19 GR 3000 litres
In 1926, three additional aircraft were modified to Br.19 GR 3000 litre specifications. They had larger fuel tanks fitted in the fuselage, with a total capacity between 2,900 and 3,000 L (640 and 660 imp gal; 770 and 790 US gal). The cockpit was moved slightly aft, and the wingspan was increased to 14.83 m (48.7 ft). The three aircraft were fitted with different engines: the first one had a 370 kW (500 hp) Hispano-Suiza 12Hb, the others had 410 kW (550 hp) Renault 12K and 390 kW (520 hp) Farman 12Wers engines. In 1927, one aircraft received a new 450 kW (600 hp) Hispano 12Lb engine, its fuel capacity was extended to 3,500 L (770 imp gal; 920 US gal) and its wingspan was further increased by 1 m (3 ft 3 in). It was christened Nungesser et Coli after the two airmen who disappeared in a transatlantic flight attempt in May 1927. A fifth aircraft was built for Greece, called Hellas, with a 410 kW (550 hp) Hispano 12Hb. [2] (Other Br.19 aircraft may have received additional fuel tanks for long distance flights, but these were not officially called Br.19 GR. Some sources mention a Belgian Br.19 GR, maybe a confusion with the Belgian Br.19 TR.)

Br.19 TR Bidon
Built in 1927 with various aerodynamic refinements and 3,735 L (822 imp gal; 987 US gal) of fuel in the fuselage. With an additional fuel tank in the wing, the total fuel capacity was 4,125 L (907 imp gal; 1,090 US gal). Five were built by Breguet and two by the Spanish company CASA. Three of the French aircraft had a 450 kW (600 hp) Hispano-Suiza 12Lb, one had a 410 kW (550 hp) Renault 12K, and one had a 340 kW (450 hp) Lorraine 12Eb. The first Bidon Hispano was sold to Belgium, and the Bidon Renault was sold to China after a Paris–Beijing flight. The third Bidon Hispano became the French Br.19 TF. [2] The second Spanish Bidon was christened Jesús del Gran Poder, and flew from Sevilla to Bahia (Brazil). [5]

Br.19 TF Super Bidon
The last and most advanced long-distance variant, built in 1929, and designed for transatlantic flight. [6] The French Super Bidon was the third Br.19 TR Hispano, named Point d'Interrogation, with a modified fuselage, a wingspan of 18.3 m (60 ft), and 5,370 L (1,180 imp gal; 1,420 US gal) total fuel capacity. [7] It was powered by a 450 kW (600 hp) Hispano-Suiza 12Lb engine, later replaced by a 480 kW (650 hp) Hispano-Suiza 12NLb. Another aircraft, with a closed canopy, was built in Spain in 1933. Christened Cuatro Vientos, it flew from Sevilla to Cuba, and disappeared while attempting to reach Mexico. [8]

Utilizing the experience with long-distance variants, this improved reconnaissance variant was developed in 1928, maybe for export purposes. It remained a prototype only (with civilian register F-AIXP). [2]
Br.19.7
The most popular of the late variants developed in 1930 with a 450 kW (600 hp) Hispano-Suiza 12Nb engine, giving a maximum speed of 242 km/h (150 mph). The first five machines were converted in France for Yugoslavia, then a number were built in Yugoslavia, and a further 50 built in France for export to Turkey.
Br.19.8
With a 580 kW (780 hp) Wright GR-1820-F-56 Cyclone radial engine, 48 Br.19.7 airframes were eventually completed as Br.19.8's in Yugoslavia. Maximum speed was 279 km/h (173 mph).

In April 1925, the factory Nakajima Hikoki KK acquired two aircraft. The purchase was the work of the well-known promoter of aviation, the Asahi Shinbun newspaper group. A production license was acquired. Nakajima offered a float-equipped version to the navy, and another was entered into a competition for maritime reconnaissance, but was unsuccessful. One plane flew again with wheeled undercarriage and civilian designation J-BBFO as a mail plane.

Record variants

Both standard and modified Breguet 19s were used for numerous record-breaking flights. The first was the Br.19 prototype, which won a military aircraft speed contest in Madrid on 17 February 1923. On 12 March 1923, it also set an international altitude record of 5,992 m (19,659 ft) carrying a 500 kg (1,100 lb) load. It was later bought by the Spanish government.

Many crews made long-distance flights in Br.19s. In February 1925, Thieffry flew from Brussels to Leopoldville in central Africa, a distance of 8,900 km (5,500 mi). Two Br.19 A2s were bought by the Japanese Asahi Shimbun newspaper and fitted with additional fuel tanks. They were flown by H. Abe and K. Kawachi on the Tokyo-Paris-London route in July 1925, covering 13,800 km (8,600 mi). Between 27 August and 25 September 1926, the Polish crew of Boleslaw Orlinski flew the Warsaw-Tokyo route (10,300 km (6,400 mi)) and back, in a modified Br.19 A2, despite the fact that one of its lower wings was broken on the way. On 8 June 1928 a modified Greek Br.A2 ("ΕΛΛΑΣ" en: Hellas), flown by C. Adamides and E. Papadakos, embarked on a long distance tour around the Mediterranean landing without incident at Tatoi airfield, Athens, on 1 July. Between 1927 and 1930, Romanian, Yugoslavian and Polish Br.19s were often used in Little Entente air races.

Breguet 19 GRs and TRs set several world records, mostly of long-distance non-stop flights, starting with Arrachart and Lemaitre's 3,166 km (1,967 mi) flight from Paris to Villa Cisneros in 24½ hours on 2–3 February 1925. On 14–15 July 1926, Girier and Dordilly set a new record of 4,716 km (2,930 mi) between Paris and Omsk, beaten on 31 August-1 September by Challe and Weiser's 5,174 km (3,215 mi), and on 28 October by Dieudonne Costes and Rignot's 5,450 km (3,390 mi). From 10 October 1927 – 14 April 1928, Costes and Le Brix flew a Br.19 GR (named Nungesser-Coli ) around the world, covering 57,000 km (35,000 mi) - though the journey between San Francisco and Tokyo was taken by ship.

The Super Bidon was created especially for the purpose of a transatlantic flight. It was named Point d'Interrogation ("The Question Mark"). Dieudonne Costes and Maurice Bellonte set a non-stop distance record of 7,905 km (4,912 mi) from Paris to Moullart on 27–29 September 1929 on this aircraft. Then on 1–2 September 1930, they flew from Paris to New York City, a distance of 6,200 km (3,900 mi) making the first non-stop east-west crossing of the North Atlantic by a fixed-wing aircraft. [12] The second Super Bidon, the Spanish Cuatro Vientos, vanished over Mexico with M. Barberan and J. Collar Serra, after a transatlantic flight from Seville to Cuba on 10–11 June 1933.

The 12Z, designated Type 89 by the company, was the final production evolution of the series of Hispano-Suiza V-12 aircraft engines. The Z model was in the middle of development when France fell to the Germans during World War II. A small number were produced before and during the war but following the occupation of Vichy France, the German occupation government did not allow full-scale production to start. After the war development would resume and small numbers were built to equip new designs, but the rapid introduction of the jet engine ended further development.

The Breguet XIV or Breguet 14 was a French biplane bomber and reconnaissance aircraft of World War I. It was built in very large numbers and production continued for many years after the end of the war.

The Bréguet 690 and its derivatives were a series of light twin-engine ground-attack aircraft that were used by the French Air Force in World War II. The aircraft was intended to be easy to maintain, forgiving to fly, and capable of 480 km/h (300 mph) at 4,000 m (13,000 ft). The type's sturdy construction was frequently demonstrated and the armament was effective. French rearmament began two years later than that in Britain and none of these aircraft were available in sufficient numbers to make a difference in 1940.
