Heh, Wulf, and it's Japanese copy, looks kind of like the ZL-100 design I did. Convergent evolution strikes again....
What's the point of the 10mm deck? Prevent strafing fighters from damaging the ship? Given angle of incidence and the kinds of fuzes normally used on aircraft cannon, that wasn't (historically) much of a problem....


On the Anvil class. nice job shoe-horning that much aircraft space onto a tiny amount of tonnage. But I have to wonder about the complete lack of armor on the design. A single destroyer could very badly damage this ship, and while it's AA battery is pretty solid, relatively small bombs will go right through a 20mm deck. Torpedos or mines are also not this ship's friend.

Actually the DL30-class is one of my oldest (above with the original name), done years ago (then with a 133mm gun). The Japanese asked for a licence to build their own...and the RSAN could always make good use of some "money".

The 10mm deck is there to provide more strength should the ship blow through some heavier seas at high speed. It´s not there for protection even though it might help against straffing planes or splinters. Keep in mind that at the time the ship was designed and will be build CANNONs are still rare as plane armament. And a 7,92mm or 12,7mm bullet won´t go through it.

The ANVIL is a small fleet carrier for sure. I expect her to be too small actually - but that´s an experience the RSAN yet has to gain. There´s not much armor because RSAN designers (hey, that´s me!) don´t expect her to go through much gun fight. And against air threats her large air group will help. The 20mm deck is the hangar deck, offering more strength than protection but might help to keep the splinters away from important areas. In fact I envision the total weight of her armor to be destributed as armored boxes around her magazins and as a local protection layer above boilers and turbines.

Finally, there´s no ship that is friend to mines and torpedos, isn´t there?

Alioth is 500 tons lighter than Anvil and only ships 55 aircraft, I think 70 is a highly optimistic number.

I assume the 4.53" are DP?

Interesting.

Its amazing how similar the destroyer leader is to one of my designs for 1931. Completely different mission, but similar hull and stats.



Why is the RSAN introducing 135mm and 115mm guns when they already have 127mm and 105mm?

Anvil will be horribly cramped with 70 aircraft onboard. She is like one of the Colossus but with about twice as many aircraft and heavy AA guns. I can't see the design being a success and will probably end up like USS Ranger.

True, a large airgroup is an advantage. I'm just a little surprised at such a large ship being so poorly armored at this time period, when we still are seeing the US fleet carriers armed with 6" or 8" guns.

A question I was wondering myself.

Quoted

Well, not many, no, but some ships are more resistant than others. This one is less resistant than most ships of her displacement.

Why not introducing a 115mm gun?

So far the RSAN fields

- a 105mm which will be too light as main gun for destroyer+ sized ships and too weak as heavy AA gun on capital ships in the long run

- a 127mm gun as main armament for DDs and similar sized/secondary warships but those are LA mounts only

- a 150mm gun wich is too heavy to be man handled for sustained fire as it is necessary for AAA or as main armament for DL size warships

So I introduced two new calibers that merge these three guns into two. Btw, the DL28 already features the 115mm gun but in a LA mount while newer ships will get the gun for DP use. The 135mm gun will be used as main or secondary battery, depending on the vessel it is used on and either in LA or DP mounts. The 135mm is about the heaviest which can be man handled, methinks based on French OTL experience with 130mm guns, but most mounts will be powered anyway.

So I can easily see a reason to introduce new calibers.

As I already said I expect the RSAN to learn 70 planes is too much for a 14kts carrier. I can see the use of about 45-50 planes per ship once this lesson is learned, probably with another half douzand in crates.

The 105mm too light as an AA gun? Not at least through the end of the battleship period. Too light as a DP gun on capital ships, yes, but too light as an AA weapon? Not likely.

It depends really. There are a few tricks that could be used. I won't elaborate at the current time.

Call it convergent de-evolution? :-)

70 planes on 14,000tons?

After 5-6 years of air ops a competent navy will be asking for more fuel NOT more planes.

I'd expect at least the carrier and the destroyer to share calibre of gun mounts. What about ditching the leaders (and their unique guns) and transfering the tonnage from cruisers to destroyers?

The DDs have no heavy AA at all?

Cheers,

What planes are the RSAN using for carriers? Because there are smaller planes in the 1920s and 1930s that might fit, at least folded up rather than later planes from the late 1930s and 1940 would would render the carrier's ability to maybe 30-50 planes....or less if they can't use the evelator or fit in the hanger.

Hey that's good to know. Just before posting the Japanese version, I was thinking about ditching the deck armor. A few seconds later I had already pressed the "Post Reply" button.

Cheers,

The DDs have no heavy AA as the RSAN think they are too small and maneouverable a target to be in much danger from planes. Probably the RSAN will later learn that the DDs will either need a heavy AA caliber gun or DP main guns.

I´m not too keen to skip my leaders. As Walter said I really like the design. Further more the RSAN has enough cruiser tonnage to build those DL and still transfer Cl tonnage to DD tonnage. But I´ve yet to build to DD tonnage limits anyway.

The DD30-class is a rebuild of the DD27-class. Thus I haven´t changed their main gun caliber. However, the next class of DDs will most likely feature the new 115mm gun like the DL28-class.

The 135mm guns will not remain unique.

Regarding fuel - what exactly do you mean?

What planes? Uh... They have wings, I guess. And some kind of power plant. 4-stroke 6 cyl. engines or so....

You´re right. The planes currently in use are relatively small. So perhaps there are reall up to 70 of them on the carrier (fighters/torpedo bombers/scouts - no dive bombers yet, this kind of technology has yet to be developed). But should we reach a WW2 level of technology I can´t see more than 45-50 planes in use like on the american CVLs....

Just make sure that the sailors do not waste that 'money' on all the drinks. :-)

Dang! I knew there was something up their sleeves when they just left the ship for a "shopping tour".....!

Regarding fuel - what exactly do you mean?

Only enough fuel and munitions for 1-2 sorties per plane with small carriers.

The DDs have no heavy AA at all?

40° elevation on the mountings is enough for long-range AA.

Italy was going to go for 2-stroke diesels with turbosuperchargers just to be a bit different. Efficiency improves considerably but size begins to be a problem.

Your joking right?

What about elastic bands?

From 1920-1940 every new design of carrier increased the proportion of fuel to planes on carriers.

Sounds like the Junkers Jumo 205 aircraft diesel and descendents to me. Fairly common engines on various large German aircraft of the 30s, I'm expecting to use them on patrol seaplanes, transports, and possibly on some heavy bombers (the Jumo 223). They're not great on planes where you have to vary the throttle speed, but for planes that do lots of cruising, they're great.
