But what happens if a pilot launches several rockets at once? To track the fisrt rocket, a Tor has to expose himself for a minute, so his location can be feed into the next rocket...
That's what we have Predators armed with Hellfires for.
And if it came down to it, saturate the bloody things with cruise missiles used as decoys, THEN slam them with the real strike aircraft. Also, these things only have about 8 rounds apiece, then they have to spend at least an hour being reloaded by a dedicated maintenance truck with a crane. So, 8 shots max, and then they're toast.
I'm not worried about giving this tactic away, because if the operators ignore the "decoys", they're not decoys any more - since they're still armed. Either way, they go ka-BOOOM. Ooops.
The only problem I see here is that this missile is supposed to go about 3060 kph, and HARM tops out at "only" 2287 kph. Could be nasty if it ever fires on a manned plane. A Predator coming in at tree-top height with a Hellfire will still ruin its day - the system apparently still has a 'hard' floor of 10 meters. And they sacrificed range for speed - 6km max range/altitude? That's 20,000 feet, give or take. Load up the B-52s with HARMs (48km-plus range) and fly them around at 50K (service ceiling) and rain down HARMs on the idiots all day long.
