Russian Federation will lay down new ships below in 1925:

Aircraft Carrier Gangut

Myak (Poppy) class corvette

Khitriy class coast defense submarine

Their Springstyles will be shown in subsequent posts.

Russian Federation will also acquire two new Seaplane Tenders and Fleet Oilers of types completed in 1924.

Four Admiral Nakhimov class light cruisers, laid down in 1924, will be completed in 1925.

Emagine the confusion of the enemy when the find out the Gangut is not a BB!

Indeed. Battleships Gangut and Sevastopol have been out of service since 1921, when they were decommissioned upon Imperator Petr Veliki class entering service. But the names are too famous to go unused for long.

I've got a Springsharp 2.0 question. When I simulate guns in turrets, the report says all my above-freeboard turret guns are superfiring. Do I not have the latest version, or is there something I'm not getting?

Well friend, it sounds like you do have the latest version of SS, because in the beginning I made the same mistake (and a few more). The stuff you enter in the "Above Freeboard" section are guns that are superfiring. If you keep it at 0, that would mean that all your guns in their turrets are on the main deck. If you have superfiring guns you enter a certain number of guns in the "Above Freeboard" spot.
I made another mistake (the other way) when simming Fuso and Nagato. Since they have AA guns on the Quarterdeck and that was below the average freeboard, I entered those guns as "below freeboard". Unfortunately, SS turned them into AA guns in casemates. Fortunately Eagle-eye Swamphen noticed that and warned me about my mistake.

and it puts the below freeboard guns into casemates with poor performance in any but light seas, even when I specify that they're in turrets. I guess I'll ignore/erase that particular warning.

Ha ha ha.

Dimensions (in feet - length * beam / 750) = 66 a/c.

Square root of misc. weight = 46 a/c.

Gangut thus has a capacity of ~45 aircraft.

The square root of 4096 is 64

You´re using a bc of 0,45 for a 13kts ship?

I also think 64 planes is way too much for her.

Also note: Dimensions only allow 61 planes (215x21,5)/75=61,something....

The rule of thumb for CVs is about using dimensions on waterline.

What you´re planning here is an early RANGER or WASP - two carriers build in the 30s and both prooved too cramped and unseccessful.

Successful carriers of her size were the INDEPENDANCE-class CVLs or the japanese RYUHO all of which carried 30 planes...

Here's Rick's notes on air group size:

Quoted

For the metric gang, divide by 70 instead; if your CV is 280 metres x 30 metres, the size limit is also 120 aircraft.

So the divisor is 70, not 75.

So the math is (215*21.5)/70 = 66

And Ranger's initial air group was 76, on 14,000 tons Standard.

http://cvproj.home.texas.net/lists/compare.htm

Wasp's air group was 84, on 14,700 tons Standard.

http://cvproj.home.texas.net/lists/compare.htm

Simulating the air groups of these ships would require an additional 1680 and 2960 tons misc weight, an increase of 41% and 73%, and thus significantly greater displacement. Therefore, both these ships are significantly more ambitious than Gangut, but not much bigger.

Sorry about the square-root mixup; I was calculating off her machinery weight. :-/

Length * beam - I was using the English measurements, in which case the divisor is 750.

Compare her to HMS Hermes, which is more or less the same size and a purpose built carrier of the same period.

Her airgroup was 20planes, and she normally carried only 12.

The Novik class destroyers, laid down in 1910, entered service in 1911. When they entered servce, they were about the best destroyer around, but times have passed them by, and its about time for a rebuild. They'll get new engines, a transom stern, trade their 45cm torpedo tubes for 53cm, add some 37mm AA, and trade their old 100mm main guns for the new 100mm/56. These changes will allow the Novik class to continue to be effective escorts in Russia's navy, and all 12 will be rebuilt in 1925 and 1926:

Looks like I have to re-do my carriers... When simming them I divided by 75. Got more planes!

Tell me about it, I still have to Redraw and resim all my cruisers Cv's and battleships in SS 2.0, seeing as I lost all the preveous designs on my old hard drive.......AAARRRRGGGGG!!!

Heh heh heh... I love it. That's just about as good as Walter's subs being crewed by Ninja.

I agree that 64 aircraft seems like a lot for a ship of Gangut's size - but Springstyle says it can be so, and as in other scenarios, Springstyle defines our physics.

Where you put the 64 aircraft is another matter. Either the ship has a double hanger (which Spring* doesn't really sim at all) or Russia's ahead of the game on deck parking.

Admiral K, do I understand correctly that this ship will have its primary battery laid out similarly to a Saratoga or Essex?
