Trivia: Although the carrier used in the movie was the U.S.S. Oriskany, for the film it was given the fictitious name of U.S.S. Savo. I do not know why that name was chosen or by whom, but it was a very ironic choice. Although many U.S. carriers have been named after famous battles that were American victories (including Oriskany), the Battle of Savo, early in WWII, was one of the worst defeats in the history of the U.S. Navy.
Trivia: During the McCarthy Red Scare, director Elia Kazan decided to name suspected Communists in Hollywood and was severely criticized for doing so. It's widely believed this film was his attempt at vindication by portraying Terry Malloy as a hero who testifies in court against his friends.
