USAF BIG DAWG is a 93-foot-long (28.5-meter) surplus Air Force Parachute Water Survival School training vessel deployed as an artificial reef in May 2021. Donated by the Air Force, USAF BIG DAWG settled upright on a sandy seabed at a depth of 104 feet (32 meters). The artificial reef offers nearly 30 feet (9 meters) of relief off the seafloor, offering divers the opportunity to explore its many levels. Holes cut in the deck prior to deployment allow access to the vessel’s mess hall, classroom and living quarters.
