3-seater reconnaissance aircraft
240 hp Salmson 9A2c water-cooled radial
A single 18 cylinder engine drives propellers on the left and right side. I am not sure of this engine model number. All the other 18 cylinder Salmson that I have seen reference to started with 18 in there model designation.
One aircraft was enlarged and converter for ground attack. It had an additional engine added to the nose.
