My ship was the PC 1546. No name but the PC stood for Patrol Craft (Pocket Cruiser) or other things depending on how you felt about her. She was actually a subchaser, 174 ft long and 24 ft wide.

PC 1546

We carried 2 depth charge racks and K guns plus a 40mm amidships a 3 in cannon forward of the superstructure, 4 dual 50 caliber machine guns and rocket launchers on the bow. A floating bomb. We never caught a sub.

We were assigned to air sea rescue duty. 3 months at Midway then 3 months at Pearl to rest then to Johnston Island then Pearl then Kwajalien and back to Pearl. In late 1953 we got a new captain and he had enough influence to get us assigned to patrol duty for Operation Castle. I was the radarman. My area was the size of a telephone booth. PC 1546

The first shot was Bravo and they underestimated the yield and ignored the wind direction change which would now drop all the fallout on us and the rest of the ships. I only recently learned that they (whoever they is) knew about the wind direction change 6 hours before they set it off. But they set it off anyway.

After the blast we had to go below decks and turn off the ventilation while the hoses we had attached all around the ship pumped seawater over us and washed us clean of radiation. It was really hot below decks but I suppose it was hotter above. Remember the Japanese fishing boat that was caught in the fallout?

Everybody had to wear a dosimeter around their neck and it was checked for the level of radiation you had absorbed. If you had gotten enough radiation you were sent home. Those of us with geiger counters would try to find the hottest spots and put our dosimeters near or in that spot hoping to get a free ride home.

No one knew the danger at that time. The hottest area was the canvas covering the front and sides of the flying bridge. We had to unlash this huge piece of canvas after each shot and tow it behind the ship to wash it clean of radiation. PC 1546

The dents are from running into ships at sea.

We were sent to Rongerik Atoll or Rongelap Island, I forget which was which. We were to check on the relocated natives from Bikini. I have 8mm film of those islands and the natives. The islands were really beautiful but I think that the natives always wanted to go home to Bikini. While we were there they set off a bomb at 5 o'clock in the morning. When it went off it lit up the sky like the sun had come up. It only lasted about 1 or 2 seconds but at 250 miles it was impressive.

It was an adventure for a 20 year old but I had nightmares for several years afterwards but no other effects that I know of. I still have my certificate hanging right above my desk at home.
