A caisson gate, constructed off heavy gauge steel with several tons of ballast in the keel, is a barrier used to dam off the open end of a dry dock. The gates originated from the U.S. Navy and range in size from 110-140 feet long and roughly 30-40 feet high, with a width of 25 feet. The first deployment of a caisson gate occurred on the Atlantic City Reef in a "patch" reef now called the William Kane Reef in honor of the first New Jersey Artificial Reef Coordinator, William "Bill" Kane Figley.

Once the structure is fully flooded, it will have no more reason to remain upright and will fall over flat.

After months of multiple delays, the SS United States finally left its longtime home of Philadelphia just before 1 p.m. ET Wednesday. The storied ocean liner's next stop is Mobile, Alabama, where it will be prepared for its final mission - to become an artificial reef off the coast of the Florida Panhandle. The American maritime icon, nearly as large as the Chrysler Building, was launched in 1951 and set the transatlantic speed record in 1952.
