The story

SMA was founded in 1997 as a 50/50 joint venture between SOCATA and Renault Sport to develop a diesel engine for light aircraft. SNECMA also entered the joint venture with a one-third interest in June 2000. The prefix of the engines changed to SR, for SNECMA-Renault. In 2005, Safran bought out the other partners to become the sole owner of SMA.

On 25 September 2020 Safran announced the sale of the SR305 and SR460 engine programs to Röder Group.
