For me, Yorktown, North Carolina, Alabama & the Texas , one carrier & 3 battle wagons, hope to make it more...
For Subs the Drum & the Balao and the Destroyer Laffey
The biggest, the Iowa Class has fared the best in preservation , all 4 commissioned are preserved.
The North Carolina, Alabama & the Texas are all different class and the Texas I think is the only dreadnought preserved.
They are still trying to save The Olympia, but they need HELP !
