UNDERSEA THREAT: Ukraine has deployed its 1st generation of submersible naval drones. Pivot mounted ducted propellors facilitate rapid dives. It's estimated that these Gen 1 submersibles carry a forward-oriented shaped charge warhead in the range of 25-30 pounds (9-13 Kg).

Could a 30 pound shaped charge penetrate a ship's hull?

The warhead could certainly damage the rudders and propellers.

Could a 30 pound shaped charge penetrate a ship's hull?

Depends on the ship, but very likely, almost certainly.

A 30 lb shaped charge can defeat most tank armor.

The scale indicates a diameter of about 1 foot. Shaped charges can penetrate about 1.5 to 7 times their diameter of basic steel plate. Most ship hulls are much less than 1.5 feet thick.

Another question is how disabling is a hole from a shaped charge on a ship?

A shaped charge typically produces a hole smaller than the diameter of the charge.

How much damage is a six or four inch hole going to do on a large ship? How easily can it be repaired?
