last I checked, missiles can't shoot down other missiles, I shot off a pair of trebs at a helios once (or it might have been cyclops or some shivan bomb). The trebs had locked on fine, but the bomb survived a good 10 seconds to make its mark on some unnamed destroyer. I tried it again with harpoons just to see if the engine would allow it, tucked in 150 meters or so behind the bomb, gave it 2 harpoons in sequence; the harpoons just kept flying. Note, the bomb was killable since it nailed it with maxims.
EDIT: Oh ya, the idea was so that you can have a countermeasure that is remote detonated and releases floating chunks of metal to simulate chaff.
