F 1 Hässlö was a Swedish Air Force wing located near Västerås, Sweden, established in the interwar period and active through the Cold War. The unit played a central role in Sweden's Royal Swedish Air Force development alongside contemporaries such as F 2 Hägernäs, F 3 Malmslätt, F 4 Frösön and F 16 Uppsala. Throughout its existence it hosted aircraft types including the B 3 Biplane, Saab J 29 Tunnan, Saab J 35 Draken and Saab 37 Viggen, working with institutions like the Swedish Defence Materiel Administration and collaborating with units such as Flygvapnets taktiska centrum.
F 1 Hässlö traces origins to early aviation activities at Västerås Region airfields in the 1920s, influenced by developments at F 5 Ljungbyhed and F 7 Såtenäs. Officially commissioned amid reorganizations following the Swedish Defence Act of 1925, it mirrored reorganizations affecting Arméns flygkår and Marineflieger. During World War II the wing adapted to neutrality patrols and air defense tasks, coordinating with Gotland assets and national commands like Mililitärbefälhavare; in the Cold War era it integrated jet fighters from manufacturers such as Saab AB and supported activities related to NORDEFCO-era cooperation precursors. Decommissioning followed the Swedish Defence Act of 1977 and subsequent restructuring affecting wings including F 8 Barkarby and F 18 Tullinge.
Located on the Hässlö peninsula near Mälaren, the base occupied land proximate to Västerås Municipality civic centers and industrial companies such as ASEA/ABB. Airfield layout included multiple runways, hangars, maintenance depots and control towers comparable to facilities at Barkarby Airport and Saabworks. Support infrastructure linked to regional railways like the Västra stambanan and road networks connecting to Stockholm and Örebro. Auxiliary installations included fuel farms, ammunition stores and technical schools akin to those at F 11 Nyköping.
F 1 Hässlö hosted fighter and reconnaissance squadrons over decades, operating models from Junkers Ju 86-era types to jets by Saab. Notable aircraft included the B 3 family, Saab J 29 Tunnan, Saab J 35 Draken, early examples of Saab 37 Viggen trials and liaison aircraft like the De Havilland DH.82 Tiger Moth. Squadrons were organized into divisions comparable to those at F 6 Karlsborg and worked alongside support units from Flygflottiljledning structures and logistical elements tied to Försvarets materielverk.
The wing performed air defense, reconnaissance, training and quick reaction alert tasks, contributing to national airspace sovereignty alongside units such as Jämtland Regiment detachments and maritime coordination with the Swedish Navy's coastal commands. During heightened Cold War tensions it executed intercept missions similar to operations conducted by F 21 Luleå and participated in national exercises including counterparts to Övning Valiant and maneuvers with Army Tactical School elements. It also supported civil missions during emergencies in cooperation with agencies like Räddningstjänsten and regional authorities in Västmanland County.
Training at F 1 included pilot conversion, instrument training and technical maintenance instruction, paralleling programs at Flygvapnets Underhållsskola and academies like Krigsskolan. Facilities encompassed runways, flight simulators, maintenance hangars and classrooms; the base liaised with industrial partners including Saab AB for systems upgrades and with educational institutions such as Mälardalen University College for workforce development. Ground defense and air traffic control training were conducted alongside exercises with units from F 16 Uppsala and tactical planning offices in Stockholm.
Noteworthy events included aircraft accidents during jet transition phases similar to incidents recorded at F 11 Nyköping and public air shows attracting dignitaries from Västerås and national leaders connected to the Swedish Armed Forces. The wing featured in national responses to airspace violations and intercepts involving foreign aircraft during the Cold War, echoing confrontations experienced by F 21 Luleå and F 10 Ängelholm. Its decommissioning ceremonies paralleled closures at F 18 Tullinge and prompted local commemorations involving municipal officials and veterans' organizations such as regional chapters of the Swedish Air Force Veterans Association.
After disbandment, much of the site was repurposed for civilian aviation, industrial use and heritage preservation, similar to conversions at former bases like Bofors-adjacent facilities and Barkarby Airport. Remaining hangars and memorials are maintained by local historical societies and museums including the Västerås Flygmuseum and community groups tied to Västmanlands läns museum. Former personnel transitioned into roles at Saab AB, civil aviation entities and regional services; the wing's historical impact is cited in works on Swedish air power alongside studies of Flygvapnet evolution and Cold War defense policy.
