In 1999, the government of Jordan executed a project to submerge an M42 Duster anti-aircraft tank in the Red Sea near the port city of Aqaba. The primary objective of the operation was to establish an artificial reef to support local marine biodiversity and provide a unique site for scuba divers.

Twenty-seven years after the tank was placed on the seafloor, reports indicate that the structure has successfully integrated into the local ecosystem. The metal chassis is now heavily colonized by various species of coral, sponges, and diverse fish populations. The site remains a popular destination for underwater tourism in the region, demonstrating the long-term viability of using decommissioned military equipment to foster marine habitat growth. While the tank was originally designed for combat, its current function is strictly environmental and recreational, serving as a permanent fixture in the Gulf of Aqaba's underwater landscape.
