GCC radars are needed for early warning, not only fire control.

the evidence is Alert system may not even work for missiles, or give very short warning (seconds to 1 minute instead of the usual 10 minutes)

If we are speaking of interception/penetration, these are also solved by Iran using several strategies that Israel/CENTCOM did not expect:

  1. use of cluster munitions
  2. exhaustion of expensive interceptor inventory (exchanging $7000 shahed drone for $3-5 mln worth of PAC-3 interceptors)
  3. Use of penetration aids
  4. Changing trajectory at the terminal stage
  5. coordinating swarm attacks (let AD to intercept SRBMs, while the real damage is caused by abundant cheap Shaheds that fly too slow and low to be detected)

I've read that NATO radars in Turkey were equally important to provide early warning to Israel. It's not far-fetched to assume that US radars in the middle-east did too. US THAAD in Israel would definitely be networked into those.

I think that there is a problem here - you're talking about the firing of the defense system at targets, whereas knowing that that radar needs to be readied because missiles have been detected is what the other radar system provided.
