Changing meaning

I don't have the references right here at hand, but my recollection is that the meaning of "Ultra" changed over time. It initially referred to just the Enigma system(s) (both Army, GAF and Navy), but eventually came to cover all high-level cryptanalytic intel. I think the same was true of the US term MAGIC, which came to cover all HLCI. If I have time, I'll try and research this issue further. J. Noel Chiappa 20:05, 24 October 2008 (UTC)
