How do you find what ship someone was on ww11?

To find out what ship someone served on during World War II, you can start by searching military service records through the National Archives or the U.S. Navy's official websites. Additionally, organizations like the American Legion or veterans' associations may have resources to help. You can also check crew lists, muster rolls, and other historical documents that might be available online or in libraries. If the individual is deceased, their service records may be requested through the National Personnel Records Center (NPRC).
