Really? Consider this scenario. A satellite locates and tracks a carrier. A submarine 200 miles away launches four very slealthy missiles which themselves each launch a flock of forty “seagulls”. Each “seagull” is an 18 inch stealthy drone packed with one pound of C4 plastique. Monitors track the flocks directly to the carriers like mosquitoes going to a prey. Science fiction? The carrier would survive? That is a very rudimentary basic scenario. Big capital ships are simply not defensible in the 21st century.
Beside, the weapon you mention doesn't exist.
I suspect that you think one pound of RDX plastic explosive does quite a lot more damage than it really does.
In any case, this weapon system of yours would be a sub-launched missile bigger than a Tomahawk that delivers 40 pounds of explosive -- in forty separate packages that somehow all need to be independently controlled to the target by micro helicopters. Even 40 pounds of TNT delivered in a single lump isn't going to knock the license plate off an aircraft carrier.
You're describing a very unlikely weapon to even make it off the drawing board.
