Söderhamn Airport — Söderhamn, Sweden

Söderhamn Airport, coded SOO, serves the town of Söderhamn along Sweden's eastern Gulf of Bothnia coastline in Gävleborg County. Once tied to Swedish Air Force operations during the Cold War era, the airfield has transitioned toward general aviation, flight training, and limited charter use as military presence in the region diminished over recent decades. The surrounding area is known for its forested landscapes and coastal fishing traditions, and SOO provides a modest but useful transport option for this part of central Sweden, situated between larger hubs like Stockholm and Sundsvall. The airport's evolution from military airfield to civilian facility mirrors a broader pattern seen across many former Cold War-era airbases throughout Scandinavia.
