The mission is composed of 4 different tasks which must be done in a maximum time of 15 minutes. The different tasks can be undertaken in any order except the first one, which must be undertaken first.
Task nº 1: Move from launch/release point and submerge. Pass through a validation gate without contacting any part of the structure.
Task nº 2: Locate a target situated on the bottom of the tank and "hit" it using a marker dropped from the vehicle.
Task nº 3: Locate a mid-water target and contact it with the vehicle. The target will be reflective (both optically and acoustically).
Task nº 4: Surface within a designated surfacing zone which will be marked by means of an active acoustic device.
