Mount Information (mount.dat)
-----------------------------

The rate of fire (rof) for the Sea Dart mounts is almost certainly wrong.
The rof of the twin arm Sea Dart launcher is 20, the rof of the single arm
Mk13 launcher (used by USN Perry class frigates) is 10, the rof of the twin
arm Mk26 launcher (used by USN Kidd class Destroyers) is 5. The rof of a 
single arm launcher is twice that of a twin arm launcher? I don't think so.
I have changed the rof of the Sea Dart mounts to 5.


Weapon Information (weapon.dat)
-------------------------------

The changes I have made here are rather more subjective (if you don't agree
with me don't use my modified weapon.dat file). I think the Pk (Probability 
of Kill/Hit) of the Sea Dart and Sea Wolf are too low. 

The latest mod of the Sea Dart has on-board autopilot (like SM-2s) so more 
than one missile can be controlled by a single fire control radar (like the 
USN's NTU system). The Sea Dart is also considered the next best thing to
a SM-2, and has been subject to a number of upgrades over the years. So, I
find it hard to believe that the Pk of the Sea Dart Mod2 is only 60%, the
same as the older Mod1 and less than either the SM-1 block IV (70%) or the 
SM-2 block I (75%). I have therefore changed the Pk of the Sea Dart Mod2
to 70%.

The Sea Wolf is generally considered one of (if not the) best Naval point
defence missiles in the world. Unlike most other point defence missiles it
is not based on a land based missile or an air-to-air missile, but was
designed from the start as a naval point defence missile. In tests it has
demonstrated a Pk in the high 80s/low 90s, it has even shot down 4.5" shells.
Like the Sea Dart the Sea Wolf has been updated from the original Mod0
standard to todays Mod3 & Mod4 standards. I have therefore changed the Pk of 
the Sea Wolf to 85%
