The Farman company developed and produced aero engines from 1915; the 12We was the company's most produced engine. Following the cylinder layout of the Napier Lion this engine featured three banks of four cylinders and employed water cooling.
The 12We was first flown in a Farman F.60 Goliath in October 1922 and later set a distance record powering a Farman F.62 in 1924, the engine ran continuously for 38 hours.
