Double Eagle SAROV

The Double Eagle SAROV is a semi-autonomous underwater vehicle designed for mine countermeasures, developed by Saab Kockums. Introduced in 2008, the system functions as a hybrid Remotely Operated Vehicle (ROV) and Autonomous Underwater Vehicle (AUV). It is engineered to detect, identify, classify, and neutralize sea mines, operating in either tethered ROV mode for disposal tasks or autonomous free-swimming mode for reconnaissance. The vehicle is built for deployment from surface vessels, submarines, or shore-based craft, housed within a standard container for logistical flexibility.

Physically, the SAROV measures three meters in length, 1.3 meters in width, and 0.8 meters in height, with a fully loaded weight of 730 kilograms. It is capable of reaching speeds of up to six knots and operating at depths of up to 300 meters. The system’s autonomy allows it to conduct search operations, underwater surveys, and Rapid Environmental Assessment (REA) without constant human intervention. When transitioning to the disposal phase, it connects via a thin fibre optic tether for real-time control and data transmission. The vehicle carries a magazine with up to three charges, providing multiple disposal solutions for different types of underwater threats. Its six Degrees of Freedom (6 DOF) movement system ensures high-precision manoeuvrability in complex underwater environments.

The Double Eagle SAROV has been adopted by several European navies, including those of Sweden, Norway, and Denmark. In October 2022, Saab received an order from Remontowa Shipbuilding S.A. for additional SAROV systems intended for the Polish Navy. These units are scheduled for delivery between 2026 and 2027 to equip the Polish Navy’s Kormoran II-class minehunter vessels. The systems are integrated into the combat management systems of these new vessels, allowing for seamless deployment and recovery using standard ship cranes. Saab states that the Double Eagle family is used by navies around the world, leveraging its modular design to suit various mission requirements from mine reconnaissance to neutralisation.

The SAROV represents a cost-efficient alternative to expendable mine disposal methods. Its robust design and short turnaround time aim to provide high availability and reliability for mine countermeasure operations. By combining autonomous search capabilities with precise remote-controlled disposal, the system reduces the risk to naval personnel. The vehicle’s ability to operate from a wide range of platforms, including crafts of opportunity, enhances its strategic utility for nations seeking to secure their maritime approaches against underwater mining threats.
