Sopwith Pup

The Sopwith Admiralty Type 9901 was a diminutive derivative of the 1-Strutter, featuring a similar wing design with 20% less area. Ground crews began calling it the "Pup," a moniker which ultimately replaced its official designation. It was deployed in 1916 to reverse the Fokker Scourge, and an up-engined version was used extensively in British homeland defense. The Pup also was the first airplane to make a shipboard landing while the ship was underway.

The Pup burns 3 gallons of aviation fuel per hour at routine usage. A full load of fuel and ammo (excluding bombs) costs $13.60.

Design Notes:

Historical wing area was 254 sf. MG load out is a guess. Design payload was 467 lbs; the historical value has been substituted. Design aSpeed was 76 mph. Performance calculations were based on historical values for wing area and loaded weight. The Body MG is synchronized, lowering RoF by 10% (see p. W:MP8). Using the calculated gSpeed at 1/6 Off-Road speed (25.5 mph) gSpeed is still 82% of stall speed, so the plane could therefore potentially get airborne in a bumpy field, at the GM's discretion.

 

Variants:

Later Pups possessed 75-kW engines.

The Dove (1919) was a two-seat civilian variant. The engine was difficult to maintain by private owners, and only 10 were produced.
