This much is doable.

You just departed our current reality.

:search for targets there" Each UAV rolls a dice, if it is in the 20%,

And what do you do if they all roll '1'? How do you even know?

:it rolls a dice to choose among the identifiable targets on the ship
phased arrays, CIWS radars, bridge, aircraft on deck, catapult).

Back into another universe.

:will be a bit more complicated, but this is the basic idea.)

A 'bit more complicated' indeed - to the point of requiring sensors
and software that don't exist in our universe running on hardware we
can't build.

: On the first shot you may hit a bunch of decoys but also
: the target or targets. Especially if the decoys must be deployed under
: the control of the central command. Second time the decoys may stay on
: and the command freqs shut down. Third time no one cares and fires
: enough weapons to take care of the site and the decoys.
:No decoys needed. The UAVs themselves are cheap enough so that would be
:waste. Perhpas you can have a hi/lo mix of UAVs with high end
:sensors/UAVs with cheapo sensors (as the sensors are likely the
:costliest part of the UAV), the cheapo UAVs acting as a sort of decoys
but still being able to inflict damage, just with a bit lower
robability.)

You REALLY need to get out more and stop watching so many movies.

: I have heard of fiber optic communications, those antennas will still
: radiate
:With autonomous UAVs, the radiation will be intermittent and low
:bandwidth. Using spread spectrum/frequency agility or whatever, it
:will be difficult to pick up out of the noise. And antennas are cheap
:and you can have plenty of them....

Yes, "or whatever" seems to paper over a massive quantity of
technological unlikelihoods and impossibilities.

: It's the occupation afterwards that is the sticking point.
:Well, I don't think US will be dumb enough to try to occupy Iran. But
:with Dubya you never know....

As if you hadn't said enough dumb**** things....
