Although the Bréguet 14 did not enter into combat until September 1917 it quickly became one of the best aircraft involved in WWI. Its exceptional robustness and 300 hp engine enabled it to be used on all fronts as a bomber and high altitude reconnaissance aircraft without any escort. Production ceased in 1926 with a production run of around 8,000 units exported to 14 nations. After WWI, the type's good performance gave rise to numerous civilian versions for commercial transport or mail transport.
