And, I'd love to see Dragon bring back the "Modern Seapower Series" that includes all USN surface combatants from USS NORFOLK right thru to the Virginia class CGN's. Not forgetting the Cleveland and Baltimore missile conversions..And the FRAM 1 & 2 stuff.
Also, circa 1970's Midway class!
Other than USN, how about USSR Krivak in 350 and 200 scale. RN HERMES (Falklands era) and ARK ROYAL (late 1970's).
