George William Thompson-Navy-WWII

I am trying to find what ship/ships my grandfather, George William Thompson, was on during WWII. And where he was stationed at. The only information I have is the date he got out of the Navy, March 6, 1943. His rank was Watertender 1st Class. And that the boiler on his ship blew up, injuring him in the abdomen. Injuries he dealt with until his death. Any ideas how I could find this information?

If there is any one still out there that served with him, I would love to have you get in touch with me.
