These photos came from a member of the 146th Seabees Fire Department, part of the Headquarters Company. They arrived on Okinawa in late July 1945 aboard the S.S. Sea Devil as you can see from the date on his Domain of the Golden Dragon - crossing of the International Date Line certificate. After the end of the war on 2 Sept, 1945 he received a Seabees Knights of the Pacific certificate dated 10 Sept 1945. I have almost no information on what the 146th NCB did while on Okinawa although I am sure they were involved in many of the constructions projects on Okinawa at the time.
