Here is one visualisation of a "what if". Three large twin-gun turrets for the 51cms, much larger central superstructure than Yamato. Otherwise profile the same.

Guys and Girls,

Looking at doing a new variant of Empire mod with less CV construction prior to WW2 but weaker treaty so more BB, kind of halfway house to WPO. Now Empire mod is pretty much ironed out, we are finding less and less to improve, I will use Scn 42 to make a new one soon.

I was ...

<t> It's not quite that simple. Accuracy is different for various weapon types (and not relevant to a large number of them).<br/>
<br/>
But let's assume you are talking naval guns.<br/>
<br/>
I have developed my own formula to "fit" values to the values assigned to devices in DBB. For naval guns ...

<t> They did carry the Type 0 Common (or HE) shell. But this was relatively low-filler (4.5% bursting charge) compared to the 2.3% for the Type 91 APC round. This would have resulted in suboptimal fragmentation against soft targets (the casing splinters into fewer, larger, heavier pieces) compared ...

I agree. It's a historical war game. Numerous place names changed from 1941 to today. Do we change Rangoon to Yangon? Port Arthur to Lushunkou? Canton to Guangzhou?

The B-339-C's had the 1,000 hp G105 Cyclones. The B-339-Ds had the more powerful Cyclone 40s (1200 hp). The B-339-23s (most of which went to Australia) had the G205.

The Japanese Type 99 20mm cannon (the Mark 1) was a continuation of the design philosophy behind the Zero - low weight at all costs. This meant low muzzle velocity and a low rate of fire. The heavier IJAAF 20mm Ho-5 cannon was far superior.

<t> Fully agree with you re the Brewsters with export Cyclones. At low altitude a Buffalo I or B-339 stood some sort of chance, at higher altitudes they were slaughtered.<br/>
<br/>
The real weakness of Japanese aircraft design was the lack of properly powerful engines. They therefore decided to ...

<t> Most of it comes down to pilot quality, numerical parity and suitable tactics. The Dutch CW-21s and even the export Curtiss Hawks could perform adequately with Zeroes and Oscars in a dogfight but they faced numerical superiority and were whittled down.<br/>
<br/>
The Zero and Oscar were ...

<t> The F4F-3 was very agile and nimble. Slightly faster than the Zero, good climb rate and in the right hands would outturn a Zero. But then they went and packed her full of additional weight (around 500lb extra) for the -4 variant, which dramatically reduced her maneuverability.<br/>
<br/>
The ...

<t> You forgot to add this bit from the Wikipedia article you took your quotes from:<br/>
<br/>
"For 54 years there was no definitive answer as to whether he had been brought down by friendly fire or the Japanese bomber's nose gunner. In 1997 the publication of the primary source for this article ...

<t> That being said, the Iowas were initially designed in response to the conversion of the Kongos. At the time (around 1938) the US designers only knew that the Japanese were violating the naval treaties, so they invoked the escalator clauses under the treaties. In mid-1938 they expanded the ...

Hiryu took 16 months from being laid down to being launched on the slip at Yokosuka Naval Yard. It then took another 20 months to commission.

The Yanks had a relatively good idea:

<t> Chalk and cheese. The Yamato's FC radar had a wavelength of 10cm and peak power of only 2 kW. That enabled her to possibly range her guns, but not train them with any level of accuracy. To do that, she remained dependent on her optics (which were excellent). The Iowas had a wavelength of only ...

Sure - was just indicating that from a modding point of view maximum sorties appears to be derived from maximum Avgas storage, in case someone wants to mod a new carrier.

Thanks for clarifying. It seems the max sorties field in the database for carriers correlate closely to a fraction of the actual bulk avgas storage those carriers had in real life, hence my assumption.

Also bear in mind that these detection tests were run in 1947, after they had had some time to iron out teething issues with these AEW sets.

<r> You might find this interesting - detection tests run in 1947 by the Evaluators squadron, who flew PB-1Ws:<br/>

They don't specify which AN/APS-20 is ...

<t> The AN/APS-20A was fitted to the TBM-3W aircraft, for use off of carriers.<br/>
<br/>
The larger-capacity AN/APS-20B was fitted to B-17Gs converted to PB-1Ws by the Navy, and intended for land-based use.<br/>

They had the same pulse widths, but the B-model had double the peak power ...
