Consider a 600' by 67' flight deck, a total of 40,000 sf. That requires a vehicle with more than 120,000 sf body area -- how much more depends on the superstructure. A 130,000 sf hull is 3,200,000 cf, after multipliers. In terms of the WWII modular rules, that would be 492k VSPs with a fine hull.
As a side note, it takes the Light Battleship chassis to get a worthwhile flight deck, the Cruisers are too small. That puts the rules as they stand into question. Still, no reason to think small, let's go with 3,200,000 cf. Fine lines give a flotation rating of 76,800 tons, and as a submarine the Lwt should be more than 80% of that (or she won't sink even if the entire volume of the ballast tanks is flooded). An Ewt of 62,500 tons and a Lwt of 75,000 tons would give some flexibility to float with a full load and to dive with empty tanks and hangars. Those numbers are insanely high by historical pre-WWII standards, but then this is no normal carrier. Drsg is 18,821, so a design top speed of 30 mph (26 knots) requires 160,000 kW engine power. Ouch. At normal speeds, the steam turbines would burn 576 tons of fuel per day, but a sub probably needs some really large diesels. With 9,000 tons of fuel, the range should be roughly 8,000 miles at 21 mph or 20,000 miles at 13 mph. _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
