The Dewoitine D.26 was a military trainer developed in Switzerland for the Swiss
Air Force in parallel with the D.27 fighter.
The D.26 airframe was similar to that of the D.27. Differences included:
* The engine cowling was omitted on the D.26;
* The D.26 radial engine was smaller and produced 340 hp power;

10 examples were built by Dewoitine for assembly by the Swiss factory K+W Thun
in Switzerland. These were followed by an order for two more aircraft equipped
with a slightly higher-powered version of the Wright 9Q engine that powered the
initial batch, and one of the original D.26s was similarly re-engined. The
original D.26s were used principally for training in gunnery and formation
flying, while the more powerful aircraft were used for air-to-air combat
training. To this end, they were equipped with gun cameras.
The D.26 enjoyed a long service life, not being withdrawn until 1948. At this
time, they were transferred to the Aero-Club der Schweiz where they were used as
glider tugs. The last example was not retired from aeroclub use until 1970,
Only 2 planes are still airworthy in original condition, number 286 is based in
Grenchen LSZG and number 284 is based in Lausanne LSGL. Both planes touring in
airshows as "Patrouille Dewoitine - Swiss Air Force 1931".
