Not only that, but because you don't need room for the powder (and all the safety armored bulkheads & systems around it), you can store a lot more of these projectiles on board. So far as warheads are concerned, E=1/2 m v^2 means kinetic energy is probably just as effective, given enough v. I think I read elsewhere the rate of fire is 5 or 6 a minute. Combine that with the 160km range, and you've got quite a good shore bombardment system. I'm wondering how well it'd do ship vs. ship, over the horizon. Presumably they'd have a drone near the target so they could adjust fire.
