The Aéronautique Militaire issued a specification in late 1917 calling for a Bn2 medium bomber (Bn2 stands for 'Bombardier Nuit 2' - Night Bomber 2, where the number means that it had to have a crew of two). It should not be confused with the other BN2 designation, intended for a heavy bomber.
The Breguet 16 was basically an enlarged variant of the Breguet 14 with a larger wingspan of 16.96 meters (55.64 ft) versus the 14.36 meters (47.11 ft) of the Breguet 14. This was done in order to carry heavier loads of fuel and bombs for strategic bombardment missions.
The Breguet 16 was powered by a single Renault 12Fe engine rated at 300 hp and was armed with two 0.303 in Lewis machine guns, mounted on the observer's position. It could carry up to 550 kg (1212.54 lbs) of bombs under the fuselage.
The prototype was flown for the first time in June 1918 with M. de Bailliencourt at the controls, a test pilot working for Breguet. According to his initial evaluation, the rudder bar had to be changed as it was too near the seat. He also recommended to relocate the throttle and, because an inability to see the ground while climbing or diving, some indentations also to be performed in the edges of the lower wings. Further testing was uneventful.
Anyway, as changes had to be made, the prototype was returned to Breguet's factory to make those suggested changes. Bailliencourt stated that Breguet was furious about the delay that those alterations caused to the Bn2 programme.
Two Breguet 16 were sent to Groupe de Bombardement 1 (GB 1) to be evaluated and soon the type was mass produced. However, it didn't make it in time to see active service as World War 1 ended. After the war, some were assigned to to the 22e Régiment Aérien de Bombardement (N) (Night Bombing Aerial Regiment - N, where the letter N stands for 'nuit', night) and the 21éme RAB (N). These units were assigned to Syria and Morocco, where they saw limited service as the nature of the conflict there wasn't adequate for a bomber of such characteristics.
One Breguet 16 was tested with an American Liberty engine, but its wing failed during static trials so it didn't fly.
In total 200 Breguet 16 Bn2 were manufactured by Breguet, Ferbois, Lioré-et-Olivier and SECM (Société d'Emboutissage et de Constructions Mécaniques - Stamping and Mechanical Engineering Company, forerunner of Amiot).
The Breguet 16 saw also service abroad:
- China: In 1923 the Fengtian Clique's warlords purchased 12 Breguet aircraft through Eurasia Aviation Corporation (a Shanghai based Chinese airline). Among those aircraft there were 4 or 5 Br. 16 Bn2 (sources are not clear about the definitive number) powered by the Renault 12Fe engine. They were delivered in November 1928 and there is not info about their operational service in China.
As we couldn't find graphical evidence of the Br.16 Bn2 serving in China, the colours and registration shown should be considered as speculative. - Czechoslovakia: The Ceskoslovenské armádní letectvo (Czechoslovak Air Service) bought an unknown number of Br.16 Bn2 bombers. They were assigned to the 1. letecký pluk (1st aerial regiment) based at Prague-Kbely. They were most likely phased-out in the late 1920s.
- Portugal: One Br.16 Bn2 was bought by the Portuguese Arma da Aeronautica Militar (Army's Aeronautical Arm) in 1921 to take advantage of the type's long range to perform a long distance flight from Lisbon to Macao, a Portuguese colony in southern China, close to Hong-Kong. This Br.16 Bn2, named 'Patria' (Homeland), flew a total of 14 stages but it had to perform a forced landing due to engine overheat at Pipar Road, British Raj on 7th May 1924. Fortunately its crew survived the landing and Patria was written off and replaced by an Airco DH.9A conveniently named 'Patria II' (Homeland II).
