This is pretty futuristic, but what about a destroyer-carrier to run with the flotilla's, but being small enough to mass produce at a rate of 2 for every 8 regular ships. Here's my attempt, built to 1918 destroyer tech.

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):

Stability (Unstable if below 1.00): 1.35
Metacentric height 1.8 ft / 0.5 m
Roll period: 11.1 seconds
Steadiness - As gun platform (Average = 50 %): 58 %
- Recoil effect (Restricted arc if above 1.00): 0.06
Seaboat quality (Average = 1.00): 1.17
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.500
Length to Beam Ratio: 9.43 : 1
'Natural speed' for length: 18.17 kts
Power going to wave formation at top speed: 68 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 16.00 ft / 4.88 m
- Forecastle (20 %): 16.00 ft / 4.88 m

- Stern: 16.00 ft / 4.88 m
- Average freeboard: 16.00 ft / 4.88 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 185.0 %
- Above water (accommodation/working, high = better): 140.4 %
Waterplane Area: 7,695 Square feet or 715 Square metres
Displacement factor (Displacement / loading): 76 %
Structure weight / hull surface area: 31 lbs/sq ft or 153 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.50
- Longitudinal: 2.21
- Overall: 0.58
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
8 planes/ 200 tons
2 torpedoes/ 2 tons
"ears"/ 5 tons(short range, 7 miles?)
radar/ 5 tons(short range, 40 miles?)
misc/ 4 tons
Comments? Thoughts? Trying to be different. Next up, the Gran Columbia version. ;D
330x35ish feet is really small for a flight deck, or is the assumption she'd carry floatplanes?
The assumption is that she would carry a small plane, about 30 feet wide, with folding wings. I don't want to use floatplanes, for the sake of eccetrity.

Yeah, you could have no island (30' wide plane on a 35f wide ship), you could only have one aircraft on the deck at a time (launching or landing) and I wouldn't want to be the pilot trying to land on a 100meter flight deck on a small 2kton ship getting tossed around. The Independence Class had a deck twice your length and 5 times your displacement and where considered pretty crappy carriers. Even CVE's had a deplacement of 10kton+ and length of 150meters.
Also, the weight of Radar and EARS is 25t? or 50t? Have to check the rules page.
You could make a decent flotilla leader style DL / CL that could launch 2-4 floatplanes, infact I had planned to do this with the UNK. However, I'm not sure about fitting even half your compliment of aircraft (in seaplane form) on a 2kton hull.
Its called the Epic Fail for a reason.
For a pilot who takes off from that ship, if he has not enough speed, it will be an Epic Fall for him from the end of the flightdeck. :D
Fail, Fail, Fail, Epicity Fail(To the tune of the Spam song)
It is biplanes, though. ;D ;D

im not sure id even want to see someone try to fly a plane off that thing...
The converted Engadine ferries had 4 or so floatplanes (short 184s) on around 2000(somewhat less I believe). But a wheeled aircraft? No thanks... epic fail is appropriate.
How big was the first lying off deck?
Hint, it was a USN test...
About 30'? the BB turret one at least. Its the landing and/or tossing about that would concern me the most.
A plane can take off from anywhere, landing is the problem.
A quick and dirty idea. Ideal as an instant airfield at any one of my million atolls.
