Hell, the Navy barely cooperates with other branches of the US Military. The Brits would be out of the question. And you are correct about the Brits helping already with technology, they shared radar before Pearl Harbor, they shared examples of their jet engine while we developed the P-80
Brits gave us: Radar, Sonar, Code-breaking insights, the Merlin Engine, the Whittle Jet Engine and far more.
The US contributed: The Manhattan project, massive license production (Packard-Merlin), gobs of shipping, the 8th Air Force (Daylight Bombing), etc and so forth.
