History

SMA was founded in 1997 as a 50/50 joint venture between SOCATA and Renault Sport to develop a diesel engine for light aircraft.^[3] 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.^{[citation needed]} In 2005, Safran bought out the other partners to become the sole owner of SMA.^{[citation needed]}

On 25 September 2020 Safran announced the sale of the SR305 and SR460 engine programs to Röder Group.^[4]
