Saab AB (originally , lit. 'The Swedish Aeroplane Corporation', acronym SAAB), with subsidiaries collectively known as the Saab Group (Swedish: Saabgruppen), is a Swedish aerospace and defence company primarily operating from Sweden. The company is headquartered in Stockholm, but its development and manufacturing operations are undertaken in Linköping.
The company was formally founded by AB Bofors in 1937, by reforming the aero engine division of company NOHAB (founded in 1930), located in Trollhättan, into a proper aircraft manufacturer. It would soon merge with aircraft manufacturer ASJA (founded in 1931), located in Linköping, in 1940, which had its own design bureau and is considered the spiritual predecessor to today's Saab AB.
