U.S. Navy Orders Saab Mk66 Undersea Target for ASW Training

Defense Feeds, Washington – The Saab Mk66 undersea target has been selected by the U.S. Navy to strengthen anti-submarine warfare (ASW) training through the procurement of four advanced underwater target systems.

The acquisition is intended to provide more realistic training environments for naval crews, allowing submarines, surface warships and maritime patrol aircraft to sharpen their ability to detect, track and engage underwater threats in increasingly complex operational conditions.

The purchase highlights the Navy’s continued investment in undersea warfare readiness as strategic competition beneath the oceans intensifies. With submarine fleets expanding across several major naval powers, realistic ASW training has become an essential component of maintaining maritime superiority.

Saab Mk66 Undersea Target Enhances Anti-Submarine Warfare Training

The Saab Mk66 undersea target is designed to simulate the acoustic and maneuvering characteristics of real submarines, allowing naval forces to conduct highly realistic ASW exercises without employing operational submarines for every training event.

Unlike basic training targets, the Mk66 can replicate different underwater signatures and tactical behaviors, creating more demanding scenarios for sonar operators, helicopter crews and maritime patrol aircraft. These capabilities help prepare personnel for detecting increasingly quiet submarines operating in contested maritime environments.

The U.S. Navy intends to use the systems during routine fleet training as well as advanced operational exercises involving multiple naval platforms. The realistic target profiles allow crews to refine detection procedures, improve tactical coordination and validate the performance of sonar systems under varying operational conditions.

By investing in modern training equipment, the Navy aims to maintain proficiency across its growing network of anti-submarine warfare assets while reducing the operational burden placed on frontline submarines.

Realistic Target Simulation Improves Operational Readiness

A key advantage of the Saab Mk66 undersea target is its ability to reproduce complex underwater scenarios that closely resemble real-world submarine operations. Modern diesel-electric and nuclear-powered submarines are becoming increasingly difficult to detect due to advances in quieting technology, making realistic training more important than ever.

The Mk66 enables operators to practice tracking maneuvering underwater targets using shipborne sonar systems, airborne sensors and integrated command-and-control networks. This type of training strengthens coordination among surface combatants, helicopters and maritime patrol aircraft during multi-domain ASW missions.

Training against sophisticated target systems also helps evaluate the effectiveness of new sonar technologies and tactical procedures before they are employed during operational deployments.

The growing emphasis on undersea warfare has driven increased investment in training infrastructure across NATO and allied navies. Simulated targets provide a cost-effective method of conducting frequent exercises while preserving operational availability of frontline submarine fleets.

Strategic Importance for U.S. Naval Superiority

The Saab Mk66 undersea target acquisition reflects the U.S. Navy’s broader effort to maintain an advantage in undersea warfare as global submarine activity continues to increase. Modern submarines play a central role in intelligence gathering, sea denial and strategic deterrence, making effective ASW capabilities essential for protecting naval forces and critical maritime infrastructure.

Recent geopolitical developments have placed greater emphasis on securing sea lines of communication, safeguarding undersea cables and monitoring increasingly active submarine operations across the Atlantic, Pacific and Arctic regions.

Realistic training systems such as the Mk66 contribute directly to operational readiness by ensuring that sailors and aircrews remain proficient in detecting some of the most challenging threats encountered at sea. Continuous training also allows commanders to adapt tactics as new submarine technologies emerge.

The contract further strengthens Saab’s position as a leading supplier of naval training systems, demonstrating growing international demand for advanced simulation technologies that improve combat preparedness without requiring extensive operational resources.

As the Navy modernizes its anti-submarine warfare capabilities, investments in training are becoming just as important as investments in new ships, aircraft and sensors. The procurement of the Saab Mk66 undersea target reinforces that approach, providing U.S. naval forces with a more realistic and effective way to prepare for future undersea operations in increasingly contested maritime environments.
