What was the reason for the redraw?
I had revisited the "square bridge" Fletcher class DDs in 2014, but I hadn't touched the earlier model "round bridge" ships. This is more of a revamping rather than a "ground-up" redraw.
Also, regarding the five inch turrets; what's the story with the barrel covers (?). I notice some turrets had them and some didn't.
These are called "bloomers" in official nomenclature (not "blast bags" as the internet erroneously calls them). They were removable canvas covers that kept saltwater intrusion to a minimum on the gun mounts, which was an issue the USN encountered throughout the war. Apparently this problem was never quite satisfactorily solved, and you see many different proposed solutions being tested on various ships as they left the different yards. The Charleston Navy Yard designed a type of sliding slat mechanism in 1944 that was chosen as the "standard", but as far as I can tell this was never adopted at every yard, and you still see the canvas bloomers on ships into the 1950s. Furthermore the bloomers were something the ship's crew could rig up if necessary, so the variations are endless.
Looks like You're aiming at doing whole WW2 USN.
I have to prevent myself from being led astray by the constant requests for pre-war and post-war ships.
Anyway, some more:
This is NICHOLAS (DD-449) as the ship appeared at Tulagi in July of 1943 after the Battle of Kula Gulf. She is camouflaged in Measure 21, like all her sisters in DesRon 21.
NICHOLAS, O'BANNON (DD-450), and CHEVALIER (DD-451) were built at Bath Iron Works to the same pattern, and all received a 1.1" quad machine cannon atop the after deckhouse, which they took to the Pacific. Further field modifications added three 20mm Oerlikons on the fantail, with only a small splinter shield ahead of the outboard guns. A fourth 20mm gun was sited above the pilot house.
This is O'BANNON (DD-450) in August of 1943. She is configured almost identically to her sister NICHOLAS (DD-449).
This is CHEVALIER (DD-451) in July of 1943, after the Battle of Kula Gulf. CHEVALIER received a 20mm Oerlikon in a small tub ahead of the pilot house, built to a pattern seen on the BENSON-GLEAVES and SIMS class destroyers.
This is CONWAY (DD-507) in August of 1943 while escorting convoys in the South Pacific. She is camouflaged in the rare Measure 18 pattern, a variation of Measure 12 that used Haze Grey (5-H) on the superstructure above the main deck instead of Ocean Grey (5-O).
CONWAY, one of the later built units, is fitted with two twin 40mm Bofors mounts - one above the shortened aft deckhouse, and one in a tub on the fantail. Both are directed by Mark 51 directors nearby. The revised aft deckhouse used on the later units required the relocation of the after/emergency conning station to the searchlight platform on the number 2 stack. The antenna trunk which provided the lead-in for the ship's TAJ radio has also been relocated to this position.
