What I was getting at was with the modern naval analogy was the following:
limited number of large, long range anti-shipping missiles
more, shorter ranged anti-missile/air missiles
some carry less capable (as in shorter ranged, smaller warhead) anti-ship missiles
Assuming no lucky magazine hits, how many Harpoons to kill a Tico, Kirov or Nimitz? How many SS-N-19 Shipwrecks?
For reference a quick Google turned up this on Kirov:
The ship is armed with the Granit (Nato designation SS-N-19 Shipwreck) long-range anti-ship missile system. Twenty Granit missiles are installed under the upper deck...
An S-300F Air Defence Missile Complex is installed on the ship, with twelve launchers and 96 vertical launch air defence missiles. The Osa-MA Air Defence Missile System is supplied by the Znamya Truda Plant based at Saratov. The ship has two double launchers and 40 missiles.
If you use the typical modern attack submarine (5 - 7kt displacement) as an example instead of a ship, 20 - 30 torpedoes or missiles and 4 - 6 launchers = not a lot of salvoes.
The way I see it you are pretty much headed for this kind of scenario now. A small number of big, nasty and/or long range missiles that are slow to reload, or more smaller ones. I don't see this as a problem myself, but it depends what kind of combat battlespace you're wanting for your game. Harpoon in space, 2300AD Star Cruiser (aka hide and seek with bazookas) or something else.
Btw, in the HH books, in OBS it was noted that a CL's anti-ship missile was 70 tons.
Hope I'm making sense.
