I would put them in order of commission, personally.
Question: Will there be wartime versions of the WWII ships as well? Just curious why you're doing mainly pre-war drawings.
I started doing pre and post WWI drawings as there were almost none of them around. Only the South Carolina and Delaware had been done, as well as some inaccurate drawings of either WWII versions, or 1941 versions of a few ships.
Almost half of these ships already have their WWII versions done by other artists, so I won't do too many of those.
