Södermanland Wing (Swedish: Södermanlands flygflottilj), also F 11 Nyköping, or simply F 11, is a former Swedish Air Force wing with the main base located in south-east Sweden.

The wing was set up outside Nyköping in 1940 as a long range reconnaissance wing with two squadrons of S 16B. After the war, the aircraft were replaced with J 9 from Svea Wing (F 8) and an additional squadron of B 3 from Västmanland Wing (F 1).

In 1946, two additional squadrons of S 18 were added.

In 1948, F 11 became the sole Swedish operator of three squadrons of S 31 when the B 3 and J 9 became obsolete.

In 1953, J 28 jet fighters were used for one year to train pilots for the introduction of the S 29 in 1954.

The S 18 squadrons were replaced by the S 32 in 1958 and the S 29s by J 35s in 1964. These four squadrons served until the decommissioning of the wing in 1980.

The airfield was used as a cargo airport from 1984 and from 1997 serves as Stockholm-Skavsta Airport (IATA: NYO, ICAO: ESKN) for international flights.

Skavsta Airfield outside Nyköping. The new establishment was completed on 14 October 1941. The airfield had two runways, one east-west of 2500 m (longest of the Swedish Air Force) and one north-south of 2000 m.^[2]
