That would have to be done in any case. The average international anti-ship missile now tends towards being twice as heavy, twice as fast, with twice the warhead weight of the Harpoon. The new anti-ship Tomahawk upgrade is still a while away (if ever), is neither terribly LO nor terribly fast, and a stop-gap in any case. Fast anti-ship and fast land attack are different sides of the same coin.

Why is it so difficult to make a Anti-ship tommy? Just take out some of the ordnance load and put a IR + radar seeker in there.
