So the Four Pipers will have half decent close in AA defence?

Barely decent... 4 total barrels of 1.1 inch guns with a deliberately lower rate of fire. These modifications are just hitting the fleet in 4th quarter 1940 and won't be completely rolled out until Q2 1942So the Four Pipers will have half decent close in AA defence?
Good work, I always thought that the Navy should have taken a look at the 37mm autocannon developed by Browning and used in the P-39 -59 series of fighters and the M 1, M 3 AAA used in the P.I. and available after 1937. It could replace the 3"/23 cal on destroyers and smaller vessels. The Navy did adopt the gun for PT boats in the SW Pacific.
I'm having a vision. I see this happening in the very near future to Greece's two battleships.

Knew it was less than Bofors, I was still looking at something better than 3"/23.the M4 37mm is a backward step.
Much less muzzle velocity even than a 1.1" let alone a Bofors 40mm.

In that case You might want to consider another weapon that the US had available in OTL from 1939
i.e. the 37mm M1.
For both AA and ASuW purposes it looks a better weapon e.g MV in the Bofors class
This was as standard US Army weapon, that served in the Pacific. It was quite heavy but "modular" so could be fitted in several positions. On a ship the weight may be acceptable especially if replacing a 3".
BTW The relatively lightweight M4 was adapted for use on aircraft from this design.
Aside: Later on there was the 37mm M9 which used larger shells for better performance (at the cost of yet more weight).
Apparently that also served as AsuW armament on PTBs in the Pacific, often replacing M4s that had been scrounged from downed P-39s.
Lol... look at my original post on this, it was the M1 37 MM that I waS suggesting. I was referring to the M1 because it was already in production. But the author told me his preference to his lightweight, dual 1.1"; with 2 mounted on DD's though I think the 37mmm a better size fit.

He had fought at Caporetto and Piave and he limped slightly due to a bullet that broke his leg in the first week of November 1918.
