Well, here they are...the various and sundry vehicles I've created that aren't
currently available on io.com. And probably some that are, but I'll try not
to repeat.
My first entry is the Aircraft Carrier I've been babbling about on the net for
a bit. I'll post the stats here, but I'm going to try to post the schematic
on a website sometime. I found it's better to start with a drawing and go
from there.
Notes on the carrier. First, I forgot a few things. Notably the armaments
loadout for the aircraft. That's OK...there's room.
Another note about the armor. I used special compound armor for the ship
hull. Most large craft don't have to worry about repeated pummeling in modern
combat. Initially, I started with the idea of a two inch durasteel hull
(which I used various nefarious methods to decide that durasteel was TL8
expensive armor, at DR168 per inch). This gave me a weight and cost ceiling,
which I was able to come under by using spaced armor...an outer inch of
durasteel, then an inner core of laminate. The void spaceing is actually the
"empty space" (much of it, at least) listed for each hull. Thie space is
filled with ablative armor. It weighs next to nothing, costs not much, and
protects quite well. Small attacks won't get through the DR252 outer hull
(it's sloped at thirty degrees). Shaped charge attacks will cut through most
armor like butter, and a carrier is too big to protect completely against such
a threat (inches of laminate armor _still_ weigh a whole bunch when you're
layering it over an entire aircraft carrier). The ablative armor provides a
ncie one-shot defense against large attacks (including slope, DR 1152 against
normal attacks, 1252 reduced by a factor of 10 for shaped charges, meaning
it's pretty immune to attacks of less than 6dx4(10) or 6dx32).
In any case, I make extensive use of the ablative armor. It's kinda spiffy.
So:
CVN-101 Constitution

Substructure2 (island support), superstructure1 (island), four CIWS
structures.

Two Mk100 Vertical Launch Cells. 50 missiles per cell. SAM-1 missile is
the ususal loadout. Details on SAM-1 to follow.

mile range. Full rotation turret. 10,000 shots per weapon. Weapon is
powered from the vehcile power plant, requires 3565KW. The pods are
arranged such that beyond 100yds or so from the vehicle, two pods can
bear on any incoming threat. Weapon details to follow, but it does 6dx4
damage.

ten complete workshops in hangar bay area; Two medical centers (one in
each hull section), Each has five operating tables and 25 roomy quarters
for 50 sick/injured people; Two 300 person mess halls; 3.15 millin cubic
foot hangar bay with 25 foot deck head (that's 126,000 sq ft); Crane with
40 ton lift capacity (external open mount); Five launch catapults, three
are bow mounted, two are on the angled flight deck. All five can be
fired at once, or three if simultaneous recovery and launch.
Crew and Passengers
Total complement: 2600 persons: 1364 sailors (130 officers); 1200
aircrew (175 officers).
Computerized electronic controls; 40 roomy bridge crew stations; 600
roomy hull crew stations; Quarters: 1130 cabins; Quarters: 305 Luxury
cabins; Quarters: 50 Luxury suites (two rooms per person, flag officers)
Limited Lifesystem, 30 days capacity; NBC Kit; 30 days provisions
Power and Fuel
Four Fission reactors, 295,317 KW power each (30% excess power).
Fuel Tanks for carried aircraft: Twenty self-sealing tanks in and around
hangar bay area; twenty more self-sealing tanks in each hull section.
Each tank holds 52,500 gal. Total Embarked fuel load 20,475,000 lbs.
Cargo and Empty Space
Hallways, walking room, Ops room/Briefing, etc: Hull: 1,105,000 cu ft
Hallways, walking room, Bridge,etc: Island: 1600 cu ft
Hallways, walking room, CIC, etc: Hangar Substructure: 1600 cu ft
Empty space in hull for spaced armor, etc: 1,000,000 cu ft each.
Cargo space: 50,000 cu ft (or just use some of the other empty space)
Subassembly Hit points:
CIWS Pods: 190HP Armor: DR160 Composite
Open Mount (crane): 3107 HP Armor: 0
Chaff Launchers: 475HP DR0
Island Superst: 8741 HP; DR160 Composite
Hangar Substructure: 801,353 HP; DR168 Metal (back, front, bottom only)
Body/Hull: 2,007,831 HP; DR1152 (1252 shaped charge); PD5
Flight Deck: 176,000 sq ft. DR336 Metal (top attacks on body and hangar are
protected by only this armor)
Extra armor for fuel tanks: DR500 Expensive fireproof ablative armor.
Note that the left and right sides of the substructure/hangar facility are not
armored. They are protected by the hull armor, since I "paid" for the entire
hull to be armored.
