-H.M.S. Hood Crew Information-
H.M.S. Hood Crew List
Updated 08-May-2009
It is estimated that as many as 9,000 men, perhaps more, served aboard the "Mighty Hood" during the operational portion of her 21 year career. Unfortunately, there is no surviving official single listing of ALL men who served in her. Here you will find our attempt at creating such a listing. We are using the few, fragmentary crew lists known to exist, Navy Lists, various official reports, public records, and most importantly of all, inputs from the families of former crew.
