Sunken Thai Tanks Transform into Thriving Artificial Reef Ecosystem
Nearly a decade after Thailand deliberately submerged 25 military tanks, the underwater structures have become an unexpected marine sanctuary. The artificial reef now supports at least 53 fish species, demonstrating the potential of creative conservation methods in Southeast Asia.

An unconventional environmental initiative in Thailand has yielded surprising results, as submerged military hardware has evolved into a productive marine habitat. In 2010, Thai authorities sank 25 tanks in a designated area, creating what would eventually become a thriving ecosystem beneath the waves.
By 2019, nine years after the submersion, marine surveys documented that the sunken tanks were supporting at least 53 different fish species. The heavy metal structures provided ideal surfaces for coral growth and offered shelter for various marine organisms, transforming what could have been waste into a functioning artificial reef system.
The initiative highlights how decommissioned military equipment can be repurposed for environmental benefit when strategically deployed. Similar artificial reef projects have gained traction across Southeast Asia, where researchers increasingly recognize the ecological value of structured underwater habitats in supporting marine biodiversity.
The success of Thailand's tank reef project offers a model for other nations in the region grappling with both military equipment disposal and marine conservation challenges. Environmental experts suggest that such creative approaches, when properly planned and monitored, can simultaneously address practical logistics while enhancing coastal ecosystem health and fishery productivity.
