The USS Bibb wreck is a former Coast Guard ship that saw extensive service to her country and took part in the invasion of Okinawa during World War II. The Bibb also served as a convoy escort, protecting cargo ships against enemy attack. The Bibb rests on her side in 130 feet of water six nautical miles offshore from Key Largo. The USS Bibb was built as a Campbell class cutter in the Philadelphia Navy Yard and commissioned in 1936 with a crew of 13 officers and 132 enlisted sailors. This class of ship was sometimes referred to as the "327s" due to their length and was named for former secretaries of the United States Treasury. The 327-foot vessel had a beam of 41 feet and drew 13 feet of water. The Bibb was armed with two 5-inch guns, 40 mm and 20 mm cannon for air defense. Twin screws gave her a top speed of 20 knots. After its launch in 1937,one of the first missions of the Bibb was to protect threatened Atlantic merchants from the aggressive tensions of the war in Europe. In 1942, the Bibb was outfitted with improved guns and enlisted into the service of the Navy for convoy escort duty. During her career, the Bibb rescued survivors from the S.S. Penmar and Henry S. Mallory, as well as being involved in the Vietnam conflict. Finally, she was decommissioned in 1985 prior to being sunk as an artificial reef.
