During the transition period from piston engine manufacture to jet engine manufacture, there was a short time when it was difficult to provide full employment for the large number of workers. For this reason the company started to manufacture Diesel engines for Volvo. Moreover, a new assembly hall was built in 1948 for printing machines.
There were attempts to develop an all-Swedish turbojet engine, but none of the prototypes went beyond the testing stage. Instead, the first Swedish-made turbojet engine was manufactured on license from de Haviland in the UK. Full-scale production started in 1949.
