USS Osmus (DE-701) was a Buckley-class destroyer escort of the United States Navy, named for Wesley Frank Osmus, a Navy aviator posthumously awarded the Navy Cross after his TBD Devastator from USS Yorktown was shot down during the Battle of Midway on 4 June 1942. Research many years later indicated Ensign Osmus survived his plane's ditching but was captured, tortured and executed by the Japanese later that same day.
