The "Fliegerstaffel 19" carries as a coat of arms a stylized swan on a blue background.

In 1939, the Fliegerkompanie 19 received the Dewoitine D.27 aircraft from the Fliegerstaffel 21 and in 1940 the conversion to Morane D-3800 took place.

The Fliegkompanie 19 was stationed in Meiringen, Dübendorf, Emmen, Thun, Kägiswil and Littau during the Second World War.

Five pilots of the Fliegerstaffel 19 also took-off on the section of the motorway N1, which was designed for this purpose at Oensingen.

Since the F-5E J-3019 was no longer in the inventory of the Swiss Air Force at the time, the J-3038 was used as squadron aircraft for the "Swans".
