AB Svenska Järnvägsverkstädernas Aeroplanavdelning

Based in Linköping, Sweden, it was established during late 1930 as a subsidiary venture of the industrial conglomerate AB Svenska Järnvägsverkstäderna (English: Swedish Railway Workshops Co).

[1] While the company was directed to share its knowledge and design experiences with other Swedish ventures, such as Svenska Aeroplan AB, ASJA were allegedly reluctant to disclose such expertise, thus such cooperation was limited.

ASJA entered talks with Bofors on the topic of creating a common company for design and manufacturing of aircraft; accordingly, in January 1937, they agreed to share the stock between them 50–50.

This new entity was intended to undertake the development and design of new aircraft in relation to the demands of the Swedish Air Force, while production activity was to be divided between the two companies' plants in Trollhättan and Linköping.

[1] While this acquisition brought about an end to ASJA's independence as well as the use of its name, its facilities became a core element of the new company's production assets, while several of the aircraft that were designed under its tenure would also be manufactured during this era.
