Cape May reef also contains large numbers of tire units and Army tanks (not shown) concentrated in the center area that appears here to be empty. This reef also received 50 redbird subways cars, which are not plotted.
The Artificial Reef Program used four types of obsolete Army armored vehicles as artificial reef materials off the New Jersey coast. These were cleaned at local military bases, loaded onto barges for transport, and pushed off at their final destination. Once the Army had disposed of its excess inventory, the program ceased, around 1999. The Artificial Reef Program has sunk almost 400 tanks altogether, far too many to list them here in this website.
The Coast Guard classification for this type was BUSL, for 'boat utility stern loading'. These boats had facilities to maintain the crew for 48 hours. They were powered by a diesel engine driving a steerable propeller, which would have made them extremely maneuverable. They were replaced by a 49-foot model.
