A revised specification 20/23 was issued which added the bomber role. Two prototypes and 48 production Fawn Mk II aircraft were ordered against the new specification in August 1923 to re-equip the home based DH.9A squadrons of the RAF, although the first two production aircraft were completed as short fuselage Fawn Mk Is. The remainder of this order were full production long fuselage Fawn Mk IIs. The Fawn Mk III was fitted with a more powerful 468 hp (350 kW) Lion V engine, while the Fawn Mk IV was fitted with a supercharged Lion VI engine.
