| | Sopwith Pup model airplane am317 |
 | | With 20% less wing span, it is not surprising that this airplane became regarded as a "pup" of the earlier aircraft. |
 | | The Pup entered service with both the RAF and RNAS in 1916, and its reputation was quickly established, either as a gem to fly or a fighter to be avoided, according to whether one was an Allied or enemy pilot. |
 | | The Sopwith Pup was powered by one 80-hp Le Rhone rotary piston engine, giving the airplane a maximum speed of 112 mph at sea level, service ceiling of 17,500 feet, and endurance of 3 hours. |
