I think the original premise was an action in the first half of WW2, prior to say Rheinubung.

the german graf zeppelin against the british ark royal and victorious

i put two ships on the british side because the airplanes of the graf zeppelin were superior (Bf 109 vs Swordfishes)

Firstly it depends when this hypothetical happens. if it is 1941-42 then the British will have Swordfish torpedo bombers, or maybe Albacores, plus Sea Hurricane and Fulmar fighters or maybe even Martlets (FAA version of the Wildcat).

However if it is in 1943-45, the the British will have Barracuda torpedo bombers, maybe Avenger bombers (they were used as bombers in FAA due to difficulty of fitting British torpedos in them) and for fighters anything from Sea Hurricanes through Seafires to even Corsairs (The Fleet Air Arm flew Corsairs from Carriers before the USN did).

Also the JU87 had a reputation as being a 'sitter' for fighters.

The Fw 190 as a carrier borne fighter is not going to work very well. It has a high wingloading, requiring a high take off and landing speed, too high to successfully take off and land on a carrier. That would have necessiated a major redesign and who knows what would have been left of its performance as we know it. In any case, it would have needed some time.

I think that the RN, USN and IJN would have gotten a lot better performance out of the CV because of operational know how. The Germans would have started from about zero - lagging 20 years behind.

When this came up on another thread it was pointed out that the catapults had raised sections that would make direct fly offs difficult/dangerous if possible at all. Now in all likelyhood give a month or 6 to test things out some revisions would have been likely but then that puts the carrier out of action for a few more months ....

Alternatively the whole force of 50 plus aircraft could be made up of 190Fs, which could interchangeably fit the roles of fighter, dive bomber and torpedo bomber. None of which would make the Graf Zeppelin as good as an Essex class or similar, but with better aircraft she could have been a half decent carrier.


Bunch of problems here. For one thing at least as she was being built catapult launch appears to be the only option. Furthermore she had enough steam to launch 18 planes from an earlier quote. Then it's something like one and a half hours before the pressure is recharged. So this limits a strike to 18 aircraft. A US CVE can put up a larger strike as can the CVL. Furthermore the US CV can thicken it CAP soon after a strike is launched if needed. Then there's the fact that Graf Zeppelin not going to carry 50 plus Fw or Stukda's probably less than 40 of such air craft.

Now all this is without even considering things like radar, doctrine, or operational experiance. Note that GZ has some problems against British CVs after 41 as some of them are capable of launching night time torpedo stikes guided by radar equiped planes.


While I don't think that a torpedo carrying Fw190 could get off the deck without using the catapault, a Fw190 acting in the fighter role should be able to take off under its own power, which would allow for escorting fighters to be provided for a strike or strenghening of the CAP following a strike launch. So a strike of 18 torpedo bombers plus fighter escort should be possible, which at least matches the maximum aircraft loadout of a CVE, this being 24 aircraft for a Bogue class or 28 for the Casablanca class. Since the original planned loadout for the Graf Zeppelin was 20xFi 167, 10xBf 109T and 13xJu87 for a total of 43, and since the Fw190 is considerably smaller than either the Fi 167 or Ju87, it should be possible to carry more aircraft, and 50 seems a reasonable number.

While the Germans had some pretty decent radar, I can't answer your points on doctrine and operational experience as the Germans had no previous carriers, and it would seem not many ideas for what to do with the one they were building. The Luftwaffe having operational control over the aircraft on board Graf Zeppelin doesn't seem to be a good thing either.

The premier source on GZ is Einziger deutscher Flugzeugträger Graf Zeppelin by Israel...yes, it's in German. But there are good English-language sources as well. Whitley's German Capital Ships of World War Two does a great job with the battleships but also has a chapter on aircraft carriers, including drawings. There was a skinny paperback by Breyer called The German Aircraft Carrier Graf Zeppelin from Schiffer Publishing that can be had cheaply. Breyer more recently did a book called Graf Zeppelin with AJ Press which may be the most complete Engliah-language technical guide. Don't get the two Breyer books mixed up. You can also get the latest issue of Warship International which features a pair of GZ articles. A book called Without Wings by Burke came out last year, I think, but I can't really recommend it.

Is there any info or pictures on this? For I haven't seen any at all (obviously!)!!! :shock:

Yeah, they were meant to maneuver the ship in the tight confines of a harbor. They could also propel the ship at a minimal speed. Bismarck could have used a set after her rudder got jammed.

:stop: Little bow propellers!?!?!?!?!

The power plant was basically the same as Prinz Eugen's. I do like those little bow propellers, though.

Sorry, I have no idea. Considering their strategic situation, I don't think they really had any use for even a well designed CV.

My impression was that her hull and power plant were well designed but now that I think of it did she use the high pressure power plants like some of the other German ships of her generation. Maybe just her hull ... but then I'm no expert.

Of course one of the areas where it was not well designed was air ops. Oops.
