Gulf's New Reefs: Battle Tanks Become Fish Homes

In 1994, over a hundred M60 battle tanks, retired from Cold War service, were intentionally submerged off the coast of Alabama to create artificial reefs. These tanks, resting between 70 and 110 feet deep in the Gulf of Mexico, have since become vital habitats for marine life. The Reef-Ex program, initiated by the Alabama Department of Conservation and Natural Resources, saw the tanks stripped of harmful materials before deployment.

Initially estimated to last 50 years as reef structures, most of the 100 tanks deployed by the end of 1994 remain functional habitats. This initiative built upon Alabama's history of creating artificial reefs, which began in 1953 with sunken car bodies and later included Liberty ships. The hollow steel hulls of the tanks provide shelter for smaller fish and attract larger predators, with algae and marine growth further enhancing their reef-like qualities.

The economic impact of these artificial reefs is substantial. Studies indicate that every dollar invested in artificial reefs can return over a hundred dollars in economic benefits through fishing and diving activities. Coastal towns like Gulf Shores and Orange Beach benefit directly as charter fishing captains, dive shops, and hotels attract tourists drawn by these unique underwater attractions, demonstrating a successful transformation from instruments of war to thriving marine ecosystems.
