The F.140, first flown in April 1924, also had 4 engines, though these were more powerful, but was slightly smaller; small numbers served briefly with l'Armeé de l'Air.

The interplane gap was large, with the upper plane held high above the fuselage by a set of four vertical centre section struts.

It had four 500 hp (373 kW) Farman 12We engines, water-cooled units with their cylinders, in three banks of four, arranged in W or broad arrow configuration.

Each engine drove a four-blade propeller, each constructed from a pair of two-blade airscrews bolted to the drive shafts at right angles.
