However I am pretty sure noone is uploading target coordinates or guiding missiles using AES 256 even, it seems. I could be wrong but I would assume something greater.
It is assumed the NSA, other than side channel attacks, cannot break AES as of 2006, still it is getting close.
"AES has 10 rounds for 128-bit keys, 12 rounds for 192-bit keys, and 14 rounds for 256-bit keys. By 2006, the best known attacks were on 7 rounds for 128-bit keys, 8 rounds for 192-bit keys, and 9 rounds for 256-bit keys.[11]"
