Her only use would have been as a carrier once the navy got wind of Fishers madness.

In a TL I have boincing around thats what happens. Her and Hood make quite a pair.

It would make a good anti-Panzerschiff and Twins hunting group using Hood's speed and Incomparable's aircraft to wound ships

most likely. But I do kinda want to see the 20 inches get used at least once against another ship

I would really try and fix this...

Try some of the suggestions above and see what you get. I think the keel depth is also too deep. Widen the beam may be necessary.

 

[jsb]

Dear god Fisher, this would've been a disaster.

Her only use would have been as a carrier once the navy got wind of Fishers madness.

I thin she would make a good CV conversion very fast 35Kn even with BB weight and very long 1000ft makes Lexington look small and slow.....

Beam between torpedo bulkheads 40.00 ft / 12.19 m

104.00 ft

Might survive U29 with "only" a 32ft TDS........!!!!

 

[Vanguard45]

Try some of the suggestions above and see what you get. I think the keel depth is also too deep. Widen the beam may be necessary.

Thanks for them

 

[Not James Stockdale]

- Torpedo Bulkhead - Strengthened structural bulkheads:
10.0" / 254 mm 556.40 ft / 169.59 m 32.16 ft / 9.80 m
Beam between torpedo bulkheads 15.00 ft / 4.57 m

I think this is the most important issue. Springsharp models the torpedo defenses by adding underwater weight a certain distance from the center of the ship. As you can see below, a 2 inch torpedo bulkhead would be good, though 3 or 4 inches might be necessary to fully model a multi-layer TDS. For a historical comparison, you could model the weight in pre-dreadnoughts and dreadnoughts with about a half inch bulkhead and in superdreadnoughts with a one-inch bulkhead. The "beam between torpedo bulkheads" impacts the space available for magazines and machinery, so a wider space there shortens the length of the citadel. In reality, there's no way you could fit the entire machinery plant and all the magazines within 15 feet, but Springsharp won't complain for some reason. For a more balanced design, this should be about 1/2 to 2/3 of the ship's full beam. The Combined Fleet Battleship Comparison page has some information on this: http://www.combinedfleet.com/b_underw.htm "System breadth" is the depth from the outside of the ship to the torpedo bulkhead, so the Springsharp stat "beam between torpedo bulkheads" would be hull beam - 2 * system breadth. The armor schemes below also show the mix of air- and liquid-filled crush compartments outboard of the bulkhead, but Springsharp doesn't model those.

Dear god Fisher, this would've been a disaster.

Love this ship. Here's a representation of the Incomparable after she was modernized in the 1930s:

 

[Seafort]

Invincible class HMS Ark Royal in 2015, following her conversion to STOVL operations:

 

[matlef]

@Seafort Are you sure that that is not supposed to be converted for CATOBAR? Is it even possible to do that with the idea to launch Eurofighters which is what it lokks like she has on deck?

I originally had a catapult in there but took it out....it was so long it seemed impractical. Just more of a thought exercise of what theoretically could be done with an Invincible class hull. Plus I had a soft spot for the Ark Royal, having visited her as a child.

 

[Ming777]

I think you mean STOBAR. STOVL means harriers and jumpjets.

 

[Seafort]

Here's another one...a timeline where a Tillman battleship is not only built, but heavily modernized (ala West Virginia) during WWII and retained during the Cold War.

You cannot ski ramp off a flight deck backwards. That is 100% loss of aircraft AND CREW.
