Optimize the RN for WWII

Not particularly, this part of naval aviation isn't as delicate as ship-borne aviation. Indeed as long as a reasonable wartime command structure is in place its better to have Coastal Command be a drain on the RAFs budget between the wars than the RNs.
The FAA was not just limited by the RAF training all of their pilots and advising on aircraft. It was also limited to only those assets that could go on a ship. This means it had very few aircraft spares, a limited supply system (one warehouse IIRC), no bases to train from, no infrastructure support of any kind outside of what the RAF let them use. These were serious handicaps in the massive wartime expansion. Keeping Coastal Command with the Navy does not just improve Coastal Command (though it may well do that), it also basically fixes all of these issues at a stroke, making the FAA (or RNAS if you want to bring that back) a more complete, more resilient and more efficient organization all around.
? Like, bigger or more of them?
How about a sniper platoon and then just pop Hitler.
A few thousand 50’ tall Royal Marines would definitely be useful….
 
Oh! And one thing! The RP Projector and mounting.
I might be having one of my blond moments but do you mean UP? I though RP was the air-to-ground rocket.

IIRC it was developed by the Army in the late 1930s in the first place and they were only adopted by the Army & RN because there was a shortage of anti-aircraft guns which ITTL won't be as severe.
When they slide that across your desk and go "We've got an idea!" have a suitable stick or sword in scabbard with which to whip them by and threaten with banishment to Penguin counting duties in the Falklands if it every crosses anyone's desks again.
BUT
What you could do is give it to the army and go "What if you put some HE in these things, would that be useful to you?"
OR

I might go to the Fifth Sea Lord and the liaison officer from the Air Ministry and say, "What if we sling some of these under the wings of an aeroplane?"

AND/OR

I might think, "What if I used these to fire an anti-submarine weapon?"
 
Ahh yes I was having a blond moment, the UP Projector, yeah you could go to the army or the airforce or see if you can work it into an ahead throwing weapon, but NOT a bloody anti-aircraft mount.

Honestly the big thing I would change with hindsight is building for a 3 power conflict rather than a 2 power conflict. That is going to force tough decisions and possibly redirect the navy to look at sea denial rather than control. It will also force innovation and could be a spur to costal command as well as the fleet air arm under navy control at a sensible date.
Basically, building plans should allow for simultaneous (or overlapping times) of conflict across the globe. Even with one hot war going on one front and a cold war going on another, the RN would need to project across the globe. No other navy needed to cover every major body of saltwater like the RN, so plenty of long endurance ships (range and accomodation) and plenty of basing facilities. Even with the US needing to cover both the vast Atlantic and Pacific, that's still not including the Med and Indian Oceans, or even much of the South Atlantic, and certainly not the North and Norwegian Seas, during the interwar period.
 
Based on the information provided by @tomo pauk and @steamboy might it be better if the Army sticks to the pom-pom instead of adopting the Bofors so we can reduce the types of gun that way?

A mass of light AA weapons is needed anyway. So I'd go for a high-velocity pom-pom ASAP, and move to the Bofors when it is ready, it was a better weapon.
RN will need to have a good, hard look at their veritable flood of cannons between 3in and 4.7in, and make the reduction in calibres there.
 
Yeah the RN should basically go "we want the http://www.navweaps.com/Weapons/WNBR_4-45_mk16.php as our heavy AA gun on cruisers and as a destroyer armament. and for fleet destroyers and battleship secondaries/carrier armament we want the http://www.navweaps.com/Weapons/WNBR_45-45_mk1.php without fixed ammunition and the mounts for destroyers, either single or double MUST have a HA fire capacity."

To avoid the dance of the calibers, also you want to have basically two different designs of mounts for each gun, a single and dual mount, and this is then a common universal mount and if the design is altered the whole lot can be updated to features the changes instead of having tons of different types of turrets.

You could put the 4.7 on the next gen AA cruisers, IE the Dido analogue, but you make sure that the turrets are all fitted with powered loading and ramming and you have a mock up turret with guns and everything and you run tests on ALL these mounts as if under attack etc and listen to the crews feedback about the mounts.

Use the Iron duke for this role as a training ship, and you have the FAA and RAF 'attack' her during these tests to see what works, and what does not.

But by standardising as much as you can, you want to reduce the logistical footprint of the classes of ships you're putting into service.

Probably can build more counties pre LNT and ditch the Yorks as a idea with the bigger budget as well. Probably no where near the 40 Counties the RN originally wanted but ca. at least get a few more....albeit definitely not getting more than 20 laid down pre 1st LNT I suspect

Would mothballing the World War One S and T class destroyers, and keeping the entire V, W Parker and Shakespeare class destroyers and destroyer leaders be worthwhile, or were they just too small and old? Re-activating the S and T classes would give 120 or so 1000 ton hulls that were capable of 34-36 knots when built. It seems keeping them rather than scrapping them in the 20s and 30s would give escort numbers a leg up. They could be converted to the long range escorts like the V and W classes were.
DK Brown in his book Nelson to Vanguard (2001), had an idea about scraping the hulls of the S and T class destroyers and reusing the low mileage machinery in new, larger escort hulls. He implied that the S and T were too small and not seaworthy enough

A passing thought: Two heavies and any combo of light cruisers in the Graf Spee battle.

Another passing thought: another heavy at Denmark Strait?

I don't know. The RN, as noted by others, has global trade protection responsibilities. Pretty much by definition, they will always have a shortage of cruisers relative to missions where a cruiser would be useful. An extra 10-15% in budget authority for a decade solves a lot of problems but it does not solve the fundamental scope of mission relative to requirements. The RN will look at their mission set and resources and likely decide that minimalist trade protection cruisers of a given type might still be desirable to save on construction, manning and operational costs if that gives them a couple of extra hulls every two or three years in a building cycle. There is a place for Yorks and Aresthustras --- perhaps there is a place for a York +500 tons in survivability and habitability enhancements compared to OTL along with American boiler additives but the RN has as much a need for quantity (as long as it meets thresholds for quality) as it does for quality in each individual unit.
 
To be fair if the RN had had its way they would have gone ham on the Counties in the 20s. That being said could perhaps see them still building the Yorks and closer to the orginally planned class of 7(maybe 4 get built?)under the circumstances of my OP along with at least the 3 counties they ordered but canceled due to the OTL LNT. As for the Artheusas not that sure they were the best idea but if nothing else I suppose their hull design did majorly influence the Didos....

You'll also want to invest in heating and cooling for the ships, so if they're in the North atlantic they can keep their crews warm, and on the China station, keep them cool.
Use this excuse
'The climate control is for the benefit of the new, expensive and delicate electronics system, not the Operators'
That's the blunt explanation used for the new USN Fleet boats and new electro-mechanical TDC for A/C instalation to keep condensation at bay

The Arethusa's were perfectly good convoy escorts and patrol cruisers, they had good range and were quite tough little things, and if I had to choose between sending a C/D or a 'Theusa, i'd send the more modern ship.

I think the RN was served well by the counties and didn't really need 40 of them. What it really needed was gobs and gobs of light cruisers and ideally what we could do in this is replace those old C and D type ships, with either more Leanders or hold off and get as many TotallynotaColonyclass into service.
 
Fortunately, there was a quadruple pom-pom. According to the Naval Weapons entry on the 2pdr QF Mk VIII it entered service in 1935-36. It also says that a twin was developed for the British Army and that 57 were built. This might have been the 2pdr designed for the Army before it decided to adopt the Bofors.

Not everything can carry an octuple pompom. You need these smaller mounts. It took years of war to get credible weapons onto the smaller ships of the fleet.
