i want Seawolf to be able to surface and shoot surface targets with a Rapier or Siren style missile (same range and damage as its normal torp) with these tradeoffs:
+ Can hit land (and maybe air)
+ Can become cloaked by Iris or a commander
+ Can traverse shallows when surfaced (min depth 17 -> 7)
- Can be hit by all weapons
- Moves slower
- Maybe cannot shoot underwater until dives again
