Attention Iran: Stealth underwater craft targets minefields
An underwater craft that can seek out and destroy mines has been unveiled. The sub, dubbed Talisman, relies on computer software that allows it to complete its mission without being guided by an operator.Most mine-disposal missions rely on either human divers or small explosives dropped from a ship. Remotely operated vehicles (ROVs) that are tethered to a boat on the surface by an umbilical cord are also used, but their cables restrict how far the craft can roam. Most of these options require the people involved to be within a few hundred metres of the mined area, which can put lives at risk. In contrast, Talisman can travel for kilometres on its own to reach a minefield. Whenever the craft is underwater, it relies on its autonomy software to navigate a course and avoid obstructions. Once it finds a target, the craft rises to the surface, communicates with an operator and waits for further instructions. It can then descend again and take out the mine with a miniature torpedo.
