I'm not sure that this is the appropriate thread to post this in, but....
My wife and I were in Charleston, SC last week and visited the carrier Yorktown (CV-10) and the destroyer USS Laffey (DD-724). This is a photo of the Laffey radio room showing a rack with three R-390As. They are of a later generation since the Laffey participated in the D-Day invasion and also in the Okinawa campaign where it was struck by 4 bombs and 6 kamakazies.
An old photo of its 38 caliber gun mount struck by a kamakaze shows the horrific damage it inflicted. About half the turret gun crew was killed.
I had to take a picture of the Yorktown ready room where so many heroes of my youth waited for their missions. I read the book "Carrier War" by Lt JG Jensen cover-to-cover a hundred times when I was a kid and remembered names of those Yorktown pilots, such as "Jumpin' Joe" Clifton, Butch O'Hare, etc.
