History

The original order was for 150 aircraft with 110 hp Le Rhône 9J rotary engines, but shortages meant most of the 94 built for Britain were delivered with 80 hp Le Rhône 9C engines. A Hispano-Suiza 8A engine was trialled in the Type BH but remained experimental. A production licence was sold to the Spanish company CECA, which built twelve in 1916.

Variants

The BB (French designation MS.7) had a Le Rhône 9J rotary and the BH (MS.8) an experimental Hispano-Suiza 8A V-8. The Spanish-built aircraft were designated CECA-MS.

Where you'll see it

It equipped several Royal Flying Corps and Royal Naval Air Service squadrons, mainly in the observation role. With a forward-firing Lewis gun on the top wing it was also used as a fighter. Spain and Imperial Russia also operated it.
