1. A system comprising:
a first component moveable to a target region of a body of water; and
a second component in the form of a projectile, the second component being physically separate from, and movable to the target region of the body of water independently of, the first component;
the first component including a charge, arranged to be triggered just before impact with the target region of the body of water, to at least partially vaporise water in the target region of the body of water prior to the second component entering the body of water, for reducing water-entry shock for the second component; and
the second component arranged to enter the target region of the body of water by passing through the at least partially vaporised water, and having functionality that is triggered by the second component being in the body of water.
