Aircraft designs rapidly increased in size and power requirements to the point where the
Peregrine was too small to be useful. Although the Peregrine appeared to be a satisfactory design, it was never allowed to mature since Rolls-Royce concentrated on refining and producing the Merlin. The Peregrine

Kestrel used supercharging for boost from the start but by the 1930s it had reached the limits of what its frame could handle in power output. There was room to improve the strength of the engine, which would allow it to run at even higher boost with only modest increases in weight. This improved the

Freeman disagreed and stated that Peregrine production should continue. While reliability problems were not uncommon for new Rolls-Royce engines of the era, the company's testing department was told to spend all of their time on developing the more powerful Merlin to maturity. As a result of the

of an aircraft engine came into common use. Charging — the compression of the intake air to increase mass flow-rate and oxygen available for combustion — of some form was a requirement for high-altitude flight and as the power of engines improved there was no reason not to use it all the time. The

requirement for the F9/37, a cannon-armed fighter (the
Hurricane and Spitfire were armed with machine guns only at this point), was curtailed and there was no further progress with the design. The Whirlwind, despite having excellent low-altitude performance, proved uneconomical compared with

The two aircraft types that used the
Peregrine, the Westland Whirlwind and the second prototype of the Gloster F9/37, were twin-engine designs – the prototype F9/37 had used the
