I believe it was descended from the RAF TR1143 VHF set which was used
very successfully in the early days of WW2 for fighter control. When the
Americans saw the successful use of VHF they took a TR1143 back to the
USA and "Copied" it and produced it as the SCR522.

You make it sound like we (the US) were doing something evil, by lending
you our manufacturing capability, and helping you with the war effort.
