Good find, thanks! I’ll be spending a lot of time on that site tonight I’m sure 
Don’t mean to plug my site all the time, but if you go to my WW2DB, you’ll also find a decent collection of National Archive (US) photographs on ships, American and Japanese (and fewer German and British ship photos). Enjoy!
