Fliegerstaffel 13 (No 13 squadron) of the Swiss Air Force was equipped with Northrop F-5 flown by militia pilots when disbanded in 2000.

Fliegerstaffel 13 wore a shield-shaped insignia with a blue outer edge, showing an eagle with wings spread out and open claws ready to capture its prey, against a white background, with the red number 13 in front of the upper wing.

It showed the stylized side view of a black wasp looking in the direction of the viewer; over its head was the number 13.

The unit was founded in 1925 under the designation Fliegerkompanie 13 equipped with Fokker C.V at Ambri Airport.

In 1945, during a reorganization, the flying staff of the Fliegerkompanie 13 was transferred to the newly created Fliegerstaffel 13.
