I never named them. The Weserflug VTOLs are known and at least a paper project.
The large helis are born from my head. They have intermeshing four-bladed rotors and are designed as heavy cargolifters. The rotors can get folded up, so the helis can get stored in the hanger. Because of the twin rotors no small aft rotor is needed (naturally...). It's a mix from a Sikorsky S-56-like hull and Kaman rotor tech. Would finally be very germanish.

I was wondering because that is one big bird!

With upcoming war rumors the US admiralty got nervous and decided to get some old destroyers out of reserve and pimp them hastily. This is a Clemson-class destroyer with 5" twin turrets. The update looks weirder than it is, the turrets are not armored, the weigth is not that much. Torpedo launchers are still there, but the magazines are filled with 5" and 40mm ammo. An ASDIC was installed with a earlier refit, but no water bombs are stored, even the bomb throwers are gone, the new main mission of the ship is now anti air support. Is there a classification DDAA/DEAA? USS Clemson was to escort USS Wasp as part of the atlantic fleet. Due to the enduring peace with Germany she saw no action and was moored at Portland with dead engines in 1948. The crew was ordered to abandon the ship, she was never sold or scrapped and is a rusty wreck in a lost corner of Portland today.

That's not going to work.
Even without armour the 5"/38 still weighs 43.4 tons. In comparison the twin 4"/50 mark 14 used on the DD-208 USS Hovey weighed just 9.4 tons
The two single (I assume) 3"/50s weighs 15.4 tons, and the two directors easily ad another 12-15 tons.
Even assuming you can remove that much weight elsewhere, all the new weight has been added higher up than before. The Clesmons were hardly a study in stability to begin with, these modifications are going to make it flip over.

Agreed, or, if it did it would only be inside the harbour. I'm afraid its the usual story, trying to fit weapons on an old hull that just could not take the extra load. These were very narrow ships, with a relatively shallow hull, and of WWI dersign, pretty well obsolete by 1940. The RN got around 50 as part of a deal between Churchill and Roosevelt; ostensibly in exchange for bases in Bermuda, but also to tie in the active support from the USA. They required a lot of refurbishment before being fit for purpose, and even then they were seriously compromised in the role of asw escort. A few were radically 'modernised' but I'm not aware of how these fared. Having said that, no doubt any warship was welcomed at the time.

Also, is this your own drawing, or one that's been 'kitbashed'

I'm not sure what the RN did with theirs, but the US replaced the 4"/50s with 3/50RF guns on those that weren't modified to transports or minelayers etc.

That would be an expensive and unsuccessful emergency refit. The twin 5"/38s would be too much for the hull to handle. Guns firing would actually weaken the hull. For an emergency refit, I would suggest going with two or three 5"/38s in open mounts if this were to become an AA destroyer. The aft director is also a bit high considering the amount of flat apace they would provide for the wind to tip. Superfiring mounts wouldn't even work well due to the additional topweight. The overall design of the Clemson class left very little room for expansion in weapons, being designed to carry a specific type from the beginning.

I've been toying around with a US Clemson class refit with very little altercation (I'm only getting to around 3 5"/38s). However, I think the RN might have better luck having their 50 vessels refitted because the ships were already being refitted anyway for RN duty. A few of these ships could get 3 twin 4"/50s to provide them a better all-around armament, yet still get a good number of lighter guns on board.
