Not sure where you got your "earth curvature calculator" from. Hopefully not the same place SamuraiBlue got his from. Here is a good one:

Even if your daredevil suicidal pilot goes down to 5m above the sea surface you will still get 27.7km detection distance.
While we are bickering on aegis radar detect range of 10miles to 30 miles if plane is flying low, keep in mind YJ12 range is almost 300 miles. If aegis ship has no AWAC support, the plane already unloaded that YJ12 and gone back long before that closing range of 10 to 30 miles. So, it's moot point anyway.

I was specifically responding to your claim that a destroyer was "surprised" because a fighter was flying super low and would not be detectable until it was only "10 miles" away, which like I said, is not a realistic scenario.

The story been told that japanese were surprised as the plane flied by. Not even mentioned 10 miles detection. That was just based on earth curve estimation.

Again, there is no "earth curve estimation" that gives you "10 miles" detection, unless your scenario is a "suicidal pilot" buzzes a "midget boat with a waterline level search radar". I gave you a radar horizon calculator. You should use it.

10 < X < 50 10 minimum, 50 maximum.

You certainly didn't give any ranges in your initial post. Regardless, please provide the online calculator that you used to make this min/max claim. Is this range rooted in physics or your personal opinion?

You should know its a fuzzy number but you try to be real hard core about it.
hey man, take it or leave it. That's that. My final offer.

Well, if an aircraft is flying at 20-30 feet (very low) and the Radar is siting up about 40 feet in the air on top of the mast, you are still going to get a detection range of something on the order of 30km.

So, for them to be surprised would mean that they were not actively operating their radar...and that happens.
