The decals are scaled specifically to 1-6000 scale Figurehead metal ship castings produced by the good folks of The Last Square.
This particular deck is sized to sku 3U4L Carl Vinson (1982)
I do not know if they will fit anyother 6k casting or 3D printed ships
VERY IMPORTANT:  The Figurehead modern CV & CVN ships come with aircraft casted on the decks.  In order for the decals to work, the aircraft will need to be shaved / sanded off the decks prior to application of the decals.   Click here for info on the process / tools I use to remove the aircraft.
