How Britain might react to an F-14 decades early

If Britain received an F-14A Tomcat in the 1940s or 1950s, would studying it leave the British unhappy with a design flaw?

They would probably be very happy to receive it and would try to figure out how it worked.

The question imagines Britain receiving an F-14A Tomcat in the 1940s or 1950s and asks whether studying its design would leave the British unhappy with a flaw. In this alternate-history scenario, the expected reaction is enthusiasm and an attempt to understand technology from a later era. The brief answer does not assess the suggested flaw or discuss particular systems and the limits on reproducing them.
