The U.S. government believes that there are an estimated 40-50 million landmines and other explosive remnants of war around the world. In an effort to combat this problem, the Humanitarian Mine Assistance (HMA) Program was established to provide nations around the world the capability to detect unexploded ordnance.

Members of Underwater Construction Team (UCT) 1 combined with members of Explosive Ordnance Division (EOD) Mobile Unit 1 from Sept. 9 – Oct. 20, 2013, in Split and Dubrovnik, Croatia, to teach the techniques of finding and mapping underwater unexploded ordnance to navy divers and special police from the countries of Croatia, Montenegro and Slovenia.

U.S. forces taught host nations side-scan sonar, magnetometer, and planning and mapping software to detect and map underwater mines.

Once the mines were located, a team of divers were dispatched to the suspected locations to provide positive identification of the hazards.

Following two weeks of classroom and three weeks of field operations, the three countries successfully mapped over four square miles of sea floor off the coast of Dubrovnik, Croatia.

The host nations were very pleased with the new technology and skills.

Petty Officer 1st Class Stankovic of Croatia said, “This technology is amazing. In the past we did everything with only divers and the searches took too long. It would have taken us years to do everything we did here in three weeks.”

Ultimately, everyone involved learned a lot about the technology, international alliances were strengthened, and three countries now have the capability to detect and map underwater ordnance to make their waters safer for the future.

UCT 1 provides responsive inshore and ocean underwater construction, inspection, repair and maintenance to ocean facilities for Navy, Marine Corps and joint forces engaged in military operations.
