The 35mm Millennium gun would qualify - that's designed to fire the
AHEAD ammo I mentioned - but I'm not so sure about the Bofors 57mm. In
the AA mode that uses radar aiming and proximity fuzes, and I'm not
sure if either would be sensitive enough to respond to a small stealthy
UAV.

I would have thought that the 3Ps range gate fusing would be ideal for
that
?

A UAV with a spinning propellor is not going to be overly stealthy, hard
to
see yes, invisible to radar ?

What makes you think UAVs are restricted to props for propulsion?

Can you give a cite for a ramjet model? Also, could you please cite a role
for a ramjet powered UAV (other than a harpoon/tomahawk - I suppose they
could be considered UAVs).

I suppose one of the reasons is the role these UAVs have at the moment. One
of their biggest advantages is their loiter time. You get the best loiter
times with a low power prop driven a/c. Also, speed is not a necessity for
recon - unless you are trying to out run an adversary. Lastly, UAVs are
expendable and prop driven aircraft are relatively cheap.

I keep hearing about how UAVs are going to take out a carrier. How the hell
much explosive can one of these craft carry? Also, if there is not some
sort of penetrator nose on the thing (more weight), the best it can do is
superficial damage to just about any vessel. I daresay, the most payload
one of these things can carry is about 25lbs.

I really have no expertise in this area, I am just speculating based on my
conjecture.
