Curiously enough, you got close. This design started as a Colorado copy then I tried to fit the Montana armament onto it (four triple 16"s) and then I tweaked and tweaked and came out like an Alsace.

Now a actual idea. Aircraft power has been proven during war and is thus enticing to have a presence always at sea when out of range of Republican Air Bases.

However, the real reason the idea is offered up is to have scouting of enemy forces occur. This would allow sighting enemy ships movements while at sea and thus maneuver to avoid. If the Flying Fish Y.II is used it would take barely over ten minutes to reach a target 20,000 yds away and report back.

That sort of time loss is acceptable. Having a heads up will allow greater chance of evading the torpedo attacks of enemy ships as well as keeping out of range of the enemy and just within range of the 11" guns of Huang Hun and Li Ming. The aircraft can also be used to launch an offensive attack, most likely strafing enemy ships and torpedoing (though torpedo is such an unrefined art).

This is in effect, a fleet escort, used for scouting and the occasional attack (when planes are used to attack, they will be used against the enemy screen, not the capital ships).

The armament is heavily anti-attack, to prevent the most ironic form of lost (lose to enemy air attack) and to try to shoot down enemy scouts as well. What is missing in accuracy of the antiaircraft fire is made up for in the volume of fire presented by the 1.6"/2-pounder "Pom-pom" which lays down almost a hundred rounds of shells per minute.

There is light anti-torpedoboat armament, but it is expected that the taskforce the escort is in will protect it from such attacks. The speed of the escort allows it operation with the Huang Hun and Li Ming.

Totally impossible.
The nearest carrier I can think of is Ryujo- and she was almost twice that size with only 33% more aircraft... and had MAJOR handling problems in any kind of real weather.
You'll need to double the tonnage to get something with that kind of air wing, at least.

That is totally discounting the fact that the ship is in NO WAY bulky enough to store the aircraft in the number you suggest- Furious managed to carry only 10 aircraft under her similarly-sized forward hanger before her total conversion... not to mention that you ain't got the deckspace needed to house a 10m elevator and sufficient flying-off deck to get the aircraft aloft- to say nothing about RECOVERY.

In short- a nice idea, but entirely too much on too little.
A similar concept for the CSA is 50% bigger and only has about 16 aircraft with 4 spares in crates.

Oh, and you have the kind of AA suite that a WWII ship would have carried with none of the operational experience that generated such a loadout.

This is the smallest 'useful' carrier I found.
The upper link is stats for the ship, the lower is US Navy photos. One especially revealing photo (80-G-236393) shows this ship- MUCH larger than yours- with 43 aircraft on her deck... and how utterly insanely the deck is packed gives you an idea of how little room there would be on your carrier. In fact, Long Island only carried 21 aircraft when in active use; this is fewer aircraft than your ship claims to be carrying on 30x3m and 7,000 TONS less!

Well these are WWI biplanes... I think this ship is a seaplane carrier so the airwing would be more reasonable then.

I think it depends. Aircraft carriers are volume sensitive as well as being weight sensitive. SS doesn't have much of a concept of volume sensitivity, other than it's idea of above and below decks space being excellent, adequate, or cramped, etc.

Assuming this is a seaplane carrier, I suspect that so many aircraft could be carried, as long as a good number of them are stowed partially disassembled to take up less space. Take a Sopwith Cuckoo for example:

Length: 28 ft 6 in (8.68 m)
Wingspan: 46 ft 9 in (14.25 m)
Height: 10 ft 8 in (3.25 m)
Wing area: 566 ft² (52.6 m²)

So lets say with wings folded or stowed alongside the fuselage, you've got a unit 28.5 feet long and roughly 14 feet wide. So on this ship's maximum beam, 4 stowed as such could be stowed abreast, but along most of the length of the ship that maximum would be 3 or maybe even 2. If the entire length of the quarterdeck is hanger, it's 196 feet long. That means 6 rows. 6x4 abreast would be 24, but realistically you're looking at more like 20, maybe 18.

So if we say 18 can be stowed in usable form, that leaves 11 or so that have to stowed below decks or elsewhere on the ship broken down. This doesn't seem too insane to me. A bigger problem may be where the relatively large number of aircraft torpedos should go.

Desertfox

The 29 aircraft are actually a typo (I think), cause he mentions only 15 torpedo bombers and 4 scouts. That would be very reasonable numbers for a seaplane carrier. The armament, now that IS a problem...

From the description of the armament layout and it's hull lines, the ship looks to be a flattop... perhaps not a true carrier, but certainly a 'flattop.' When I read it, I pictured a vessel similar to the following ship classes (links to ships):
HMAS Albatross http://en.wikipedia.org/wiki/HMAS_Albatross_%281928%29
U.S.S. Langley http://en.wikipedia.org/wiki/USS_Langley_%28CV-1%29*
Akitsu Maru http://www.warshipsww2.eu/lode.php?language=E&period=&idtrida=1184

Such a ship is constructed specifically to carry aircraft in a hanger below decks, and to launch them from a flying-off deck. Given the way that such a ship is constructed, it'd be impossible to get a ship this small to function in that way. There's just not enough volume to get it to happen.


Also, Guinness... I think that having folding wing aircraft on this ship is putting the cart before the horse. Aircraft with folding wings were a product of shipboard aviation rather than an enabling agent. IMO, unless a nation has real carrier tech (at least 1918 level, where aircraft are being stored in hangers aboard ship) then they shouldn't have made that 'leap of faith' to have the wings of an aircraft fold up for easy storage.

DF, you are aware that ships nearly twice the size of this one only had 35-ish plane strong air wings... right? The number is at least 1/3 again as large a complement as this ship could be carrying, if the ship is carrying small scouts. It's likely twice as large as it should be if the ship is carrying something able to carry a torpedo.
