In 1947, F 12 was converted to a fighter wing by replacing the light bombers with the J 21A-2 which were upgraded to -3 before they were obsolete.
The airfield has been used for general and commercial aviation as Kalmar Airport (IATA: KLR, ICAO: ESMQ) since 1980.
Blazon: "On blue cloth in the centre the badge of the Air Force; a winged two-bladed propeller under a royal crown proper.
In the first corner from a waved base a yellow tower embattled issuant between two mullets".
[3] ”Kalmar flygflottiljs marsch” was composed by Bo Hartog, the wing's music director.
