MINE COUNTERMEASURES (ORTHODOX SYSTEM)
Take something like mine
countermeasures, for example. Finding and destroying mines -- particularly those
placed on the bottom in relatively shallow areas such as ports and rivers -- is a
really tough problem.
Presently itís often done as portrayed on this slide.
Here a minehunter ship uses an underwater sonar to locate the mine, or what resembles a mine. Then it directs a submersible robot vehicle to proceed over to the object and examine it with an underwater television camera. If itís a mine, the submersible places a remotely-operated charge beside it. then chugs away. When it reaches a safe distance away, the charge is exploded, causing the mine to detonate.
A very painful process. Very time consuming, and very difficult.
