I'm sure we already discussed that but here is what I found on the subject. With the war building up, several US ships which had been mouthballed sometimes for years are slowly put back into commission.

My take would be:
4 Essex-class Aircraft Carrier (Bennington, Hornet, Lexington and Oriskany). In fact I found 6 around but I consider that 2 are to be used for spare parts and 1 (Lexington) had just been decommissioned).
2 Des Moines-class Cruisers (Salem and Des Moines). The last being used for spare parts.
12 Forrest Sherman-class Destroyers (Very recently taken out of service)
4 FRAM modified destroyers
6 Terrebonne Parish-class LST (or similar ships)
3 GUPPY program submarines
Several Asheville-class Corvettes
Several PBR and PCF River Patrol Boats

Brooke and Garcia-class frigates are up to you. For my part they had not been decommissioned. Same thing for the 3 Barbel-class submarines.

I didn't include auxiliary ships as they are much more numerous

To note, some of these types such as the FRAM, GUPPY and T.Parrish are still found in large numbers in foreign navies. I tend to have most FRAM being delivered to the carribeans where they end up fighting the Mexican ones.
