Re: F-22 Raptor: The New Threat to the PLAAF
IDonT said:
The main question is how vulnerable is your UAV signals from interference. It would not be a hard stretch of the imagination for a US ELINT aircraft to hack onto your controls and use your UAVs against you.
A pre-programmed UAV that fly to a kill-box and utilize computer AI and optical imaging to ID and attack targets, would not require live data link/control.
The Israeli Harpy, for an example, is a primitive "fire and forget" attack UAV that requires no manual input after it's deployed. The Harpy system is designed to be fully autonomous in target acquisition and attack:
"The Harpy mission is planned and programmed in the battery ground control center, as an independent mission, or planned in accordance with other manned or unmanned systems. The drone flies autonomously enroute to its patrol area its radar seeker head constantly search for hostile radars. Once suspicious radar is acquired, Harpy compares the signal to the library of hostile emitters, and prioritizes the threat. If the target is verified, the drone enters an attack mode, as it transitions into a near vertical dive, homing on the signal. The drone is set to detonate its warhead just above the target, to generate the highest damage to the antennae, and surrounding facilities. If the radar is turned off before Harpy strikes, the drone can abort the attack and continue loitering. If no radar was spotted during the mission, the drone is programmed to self destruct over a designated area. Follow-on systems which are already proposed to foreign clients, are calling for a combination of seeker and killer drones that will enable visual identification and attack of targets even after they turn off their emitters."

My opinion is that, it's a LOT easier to build a "stealth" UAV or Cruise Missile, than a stealth plane. The Kongsberg NSM is one example:
Rather than sending fighters to oppose enemy aircraft, you'd simply launch stealth UAV & cruise missiles to attack enemy airstrips and aircraft carriers. The enemy anti-missile defense system will have to combat against sea-skimming stealth anti-ship missiles with extremely low radar cross section.
UAV's are excellent vehicles to both mass-deploy & extend the range of cruise missiles. Unlike expensive fighter planes, it's cheaper to mass-produce UAV's and cruise missiles, lowering the overall cost per unit. If you can lower your cost per cruise missile to $500,000 each, for the price of a $100 million stealth plane, you can buy 200 missiles.
