In its short operational career, the squadron claimed twelve wins and was credited with seven verified aerial victories.

To support this advance, 11ème Escadrille moved to Moerkerke near the Dutch border on 30 October 1918[4] After the armistice, 11 Squadron participated in the occupation of Germany.

It operated from Bochum until 5 July 1919, when it was recalled to Sint-Agatha-Berchem, in the outskirts of Brussels, where it is disbanded in August 1919.

To improve mobility and the possibility of deployed operations, each group comprised a maintenance squadron, a field train of about 25 vehicles, and an anti-aircraft unit of 40mm Bofors guns.

Commanded by Captain Henri de la Lindi, 11 Squadron took an active part in the 18 days campaign.

On the morning of 10 May, 11 Squadron rejoined its diversion airfield at Hannut, few hours before Bierset was bombarded by Dornier 17's of the Luftwaffe.

It was equipped with de Havilland Mosquito NFXXXs, and the squadron insignia was a grey bat on a yellow triangle.

The first delivery of its successor, the Dassault Alpha-Jet took place on 7 December 1978, and as of 1979 the students started training on this aircraft.

The mission of 11 Squadron was now to provide Initial Operational Training (IOT), combining simulated air-to-air combat and air-to-ground tactics.

The Inertial Reference System updated by GPS, combined with a Head-up display provided the possibility to simulate tactics used on the F-16.

Students and instructors fly out of a unit, combining the insignia and traditions of the Belgian 11 Squadron and the French SPA73 and SPA78 to form the Escadron de Chasse 2/8 "Nice".

On the 05th of Oct 2020 the unit officially moved to a newly built facility at Beauvechain (1W) Airbase upon which the 11 SQN is back in its former location.
