WASHINGTON, Aug. 26 (Reuters) — One hundred M60 tanks, stripped of guns and fuel, have spent 31 years building a reef in the Gulf of Mexico that politicians cannot name away.
The Cold War machines were sunk in 1994 under Alabama’s artificial reef program. They now host a marine ecosystem that scientists describe as rivaling natural coral formations. The renaming dispute over the “Gulf of America” is a surface-level argument. The biomass below does not care.
The tanks were cleaned of weapons, fuel, and hazardous materials before deployment. Alabama coordinated with the U.S. military to place them in two clusters about 65 feet deep. The goal was fishing economy support.
Data from recent diver surveys shows encrusting corals, sponges, and algae covering more than 70 percent of the tank surfaces. Fish biomass on the reef is estimated at 2.4 tons per acre, comparable to healthy natural reefs in the region.
Red snapper, grouper, and amberjack are the dominant commercial species. The reef has also become a breeding ground for sea turtles.
Trump signed an executive order to rename the Gulf of Mexico as the Gulf of America on his first day back in office. Mexico’s government objected. International charters have not adopted the name.
The ecological reality is indifferent to the executive order.
Alabama’s reef program spans over 1,200 permitted sites. The M60 tanks are among 500 military vehicles deployed since the 1990s. The program’s annual budget is $2.3 million. Return on investment, measured in recreational fishing revenue alone, is estimated at $18 million per year.
A parallel naming battle is playing out in Mobile. State Senator Jack Williams introduced a resolution to name the Mobile Bridge after singer Jimmy Buffett. The proposal has drawn bipartisan support.
An opinion piece in the Alabama Political Reporter argued the bridge should honor Buffett’s Gulf Coast legacy. The singer died in 2023. The bridge spans Mobile Bay, near his adopted hometown.
The debate mirrors the Gulf naming fight. Both are exercises in political branding. Neither affects the function of the structure.
Marine biologists point to a larger trend. Artificial reefs from ships, planes, and concrete modules are being deployed globally. Over 3,000 such structures exist in U.S. waters alone.
Critics call it organized dumping. Evidence suggests otherwise. A 2022 study in the journal *Marine Ecology* found artificial reefs support species richness at 87 percent of natural reef levels within a decade of deployment.
The Gulf of Mexico produces 14 percent of U.S. commercial fishing landings. Its value is measured in ecosystems, not executive orders.
The M60 tanks will outlast the political cycle. They will outlast the naming dispute. They may even outlast the oil platforms that dot the same waters.
The Gulf’s true empire is underwater. It was built in 1994. It does not require a name.

💡 Frequently Asked Questions (FAQ)
- Q: Why were 100 M60 tanks sunk in the Gulf of Mexico?
- A: They were deployed in 1994 under Alabama’s artificial reef program to boost fishing economy and create marine habitats.
- Q: How has the tank reef impacted marine life?
- A: Over 70% of tank surfaces are covered with corals, sponges, and algae, supporting 2.4 tons of fish biomass per acre, comparable to natural reefs.
- Q: Does the ‘Gulf of America’ renaming affect the reef?
- A: No, the ecological system is indifferent to political naming; the reef thrives regardless of geopolitical disputes.
