Escadrille 15 is one of the oldest units of the French Air Force, which was founded on 22 August 1912 at Reims, France, and is still active.

In September 1915, it traded machines again, gaining Nieuport 11s and being renamed Escadrille N 15.

Under the command of Capitaine Paul de Peuty, this groupe was committed to the Third Battle of Artois.

The escadrille was detached again from 17 March to 6 June 1917, to support VI Armee.
