5. USS Grayling Identification Plate
U. S. S. GRAYLING
SUBMARINE
SUNK HERE
TELEPHONE INSIDEThe above brass plate is the only remaining identification of the USS Grayling lost in WWII. It was removed from the forward marker buoy on December 7, 1941. Plate was mounted on top of buoy that could be released from inside the sunken submarine in peace time. All identification is removed from submarines in war time.
USS Grayling (SS-209) was the tenth Tambor-class submarine to be commissioned in the United States Navy in the years leading up to the country's December 1941 entry into World War II. She was the fourth ship of the United States Navy to be named for the grayling. Her wartime service was in the Pacific Ocean. She completed seven war patrols in the following 20 months and is credited with the sinking of over 20,000 tons of Japanese merchant shipping and warships. Grayling received six battle stars for her World War II service. She was declared lost with all hands in September 1943. Her fate remains an unsolved mystery.
