O-2H airframe with a swept-back upper wing and a Pratt & Whitney Wasp engine.

In 1952, the production of Wasp engines was transferred to P&WC so P&W could concentrate on developing jet engines.

It was powered by 4 Pratt & Whitney R-2800 Double Wasp engines.

First flight took place on July 14, 1932 and the prototype was powered by a Wasp engine.

The long "hose nose" visibility problem and the enormous torque of the Double Wasp engine also created operational problems.

The new aircraft was smaller, lighter and more agile than the ones it replaced but still used the Wasp engine of the F3B.

Aside from slight dimensional variations, military equipment carried, and the performance ratings of its Wasp engine, the naval fighter was very similar to its Army antecedents.

This company designed and built the original Wasp radial engines that powered Amelia Earhart's Electra.

About twenty-five thousand dollars, for a Cosmos with a Wasp engine, on floats.

Afterwards there was speculation that its experimental Hamilton Standard propeller prevented the Wasp engine from running at full power.
