Interesting article in Aviation Leak & Space Technology about the Chinese air defence system, built of standard telecoms/IT stuff. Encrypted IP over many different bearers, landline fibre rather than microwave, that sort of thing. Two things come to mind:
1) Americans; can you just accept that Huawei exists and its engineers are competent? OK? You don't need to postulate Dr Evil stories. Thanks.
2) If you read the link you'll see that the US Marines are experimenting with jammers on a UAV controlled from a PDA-like device. This is cool, but in a world of Bug Labs, you've got to reckon the other side will have them.
