Traditionally, mine reconnaissance was performed by a mine countermeasures (MCM) ship with a hull-mounted or towed sonar – which consumes both time and resources.
The Double Eagle PVDS – a remotely operated vehicle (ROV) – takes a new approach. It runs several hundred meters ahead of the ship, using sonar to detect any underwater mines.
The Double Eagle PVDS's Launch and Recovery System (LARS) allows for a smooth, safe beginning and end to each mission.
The ROV is connected to the ship via a tether, which provides vehicle power and control signals, as well as real-time sonar data to the operator on board the ship.
The Tether Protection System (TPS), the TPS launcher, and the Automatic Tension Control Forced Cooling (ATC-FC) allow the Double Eagle PVDS to operate without the risk of tangling the tether with other underwater ship systems. These features also provide additional stability to the vehicle when decoupling the ship's movements from the vehicle.
Using a control system, the operator in command maneuvers the Double Eagle PVDS remotely from the ship. They merge the vehicle with a track defined from the ship's tactical system.
The operator can change the track of the vehicle at any time by sending new waypoints, or they can manually control it and pilot the vehicle to investigate an object of interest. This capability allows for detection of Mine-Like Objects (MLOs) and prevents ships from accidentally sailing over suspicious items.
The Double Eagle PVDS's dynamic routing capability also allows the vehicle to operate under different layers in the water, even in adverse conditions and strong currents.
The vehicle has unlimited endurance and an operational depth of 500 meters.
The Double Eagle PVDS's forward-looking sonar is carried in the bow of the vehicle. The sonar is rotatable and tiltable, which increases its detection range and enhances situational awareness.
The forward-looking sonar enables high-performance detection and classification of MLOs in the most difficult environments.
The Double Eagle PVDS also boasts six degrees of freedom, meaning that it can be moved forward and backwards, up and down, and left and right.
