Wet Thrust - Conversion of FT to WWII

I've just embarked on modifying FT into WWII for a beer and pretzels
game
of What If... for instance if the Bismark and Tirpitz had survived to
take
on the British Home Fleet or if the Japanese had managed to take down a
carrier or two at Pearl and left the Americans with only crisers and
battleships to slug it out with for the middle years of the war.
Scenarios such as Musashi vs Iowa class or even a quick and dirty
version
of Midway that is playable in an afternoon.

I've currently made the following modifications -
Range bands are now 6", 12", and 18" for C,B, and A batts respectively.

Torps are range 6" with a to hit number equal to or less than the number
of torpedoes fired.  Armor reduces the damage done by torps.

Ships are assigned weapons based on historical data

Max velocity is rated at 1"= 5 knots with 1/2" being the smallest
increment

Acceleration is 1/2", 1" or 2" for Capital, cruiser and escorts
respectively

Carriers are rated for full complement of aircraft - e.g. Enterprise =
90
aircraft, 50% fighters, 25% dive bombers, 25% torpedo bombers

Dive bombers hit on a 6, damage = 1d6 - deck armor level

Full carriers can launch or retrieve 2 squadrons (12 planes total) per
turn, escort or light carriers only 1.	Carriers can either retrieve or
launch but may not do both in one turn.

There are a few other details but this is the general gist.  The aim is
to
maintain FT simplicity in terms of calculating damage and movement to
allow actions of 30+ ships that can be completed with only 5-10 minutes
per turn.

Comments are welcome.
