Wärtsilä ELAC SCOUT

Wärtsilä ELAC SCOUT is a forward looking 3D active sonar designed for mine and obstacle avoidance. It provides navigation support in dangerous waters. The system's high efficiency and extraordinary range performance are completed by a forward looking bottom mapping mode for tactical seabed survey. The system features a surface mapping mode for collision avoidance during surfacing operations.

Wärtsilä ELAC SCOUT can be installed in new designs or refitted on existing submarines. Wärtsilä offers customisation of the arrays to match the shape of any submarine.
