Nohab Flygmotorfabriker AB was founded in Trollhättan, Sweden, in 1930 to produce aircraft engines for the Swedish Board of Aviation. As the name of the company indicates it was a subsidiary to NOHAB. In 1937 it became a part of the newly founded SAAB but already in 1941 Volvo acquired a majority of the stock and the name was changed to Svenska Flygmotor AB (SFA), and later on Volvo Flygmotor.
Since the 1950s the company have been the major engine supplier to the Swedish Air Force. The Volvo Aero Group has 3,600 employees and in 2003 had total sales of 0.9 billion euros. Today Volvo Aero is a partner in more than ten commercial engine programmes. Components from Volvo Aero are installed in more than 90% of all large commercial aircraft engines sold.
On 6 July 2012 Volvo Aero was acquired by the British aerospace manufacturer GKN in a SEK 6.9 billion deal.
Svenska Flygmotor also designed the B42, horizontally-opposed four-cylinder engine, intended for the SAAB Safir. However, SAAB decided on using engines from de Havilland and Lycoming for the Safir. In the end the B42 came to power the Infanterikanonvagn 103 assault gun. A follow-up called B44 powered the Pansarbandvagn 301 armoured personnel carrier.
Volvo Aero delivers engine components, mainly complex engine structures like turbine exhaust casings, turbine mid frames, LPT cases, compressor housings, LPT shafts, vanes, and large rotating parts.
