Why is this P-40 called a "Kittyhawk?"

The small-jawed B and C models were called Tomahawk by the RAF. Both
Curtiss and the British regarded the big-jawed P-40D as new enough to
warrant a new designation, so it became Kittyhawk I in RAF service.

The AVG Flying Tigers likewise used this term for the P-40Es that were
ferried to them in the spring of 1942, though they were straight USAAF
variants.
