Outsmarting threats for a safer world

And now, amidst the vast expanse of the sea, a new tool is emerging to give naval forces the edge they need: the Naval Laser Warning System (NLWS). The state-of-the-art NLWS is poised to contribute significantly to the frigate’s situational awareness and self-protection capabilities. With rapid threat warning and threat classification, it enables the combat management system to employ effective countermeasures against the laser threats, contributes in our shared mission of keeping people and society safe.

Laser warning systems have long been essential in ground and air combat, but their application at sea is a relatively new frontier. Saab, with over five decades of expertise in electronic warfare, stands at the forefront of this innovation. Francois Raubenheimer, Marketing Executive for Saab EW Naval, reflects on the journey of its development spanning more than three decades. From its humble beginnings in 2002 to the present day, where demand for the system has skyrocketed, the evolution has been swift yet steady.

In a fraction of a second

In mere milliseconds, the Naval Laser Warning System swiftly detects radar or laser signals, serving both to locate adversaries and protect our own forces and platforms. The system can identify various types of lasers- including beam lasers, designation lasers, rangefinders and powerful blinding lasers, comparing them with its extensive signature database. Additionally, new signals can seamlessly integrate into this database upon request.

While the mechanics of laser warning systems are intricate, their operation is straightforward: when a laser beam targets a platform, the system rapidly recognizes the threat, providing critical data about the emitter almost instantaneously. Not only does it determine the type and origin of the signal, but it also calculates the direction from which it originates. Currently boasting an accuracy of 7.5 degrees, with ongoing efforts to achieve a remarkable 1-degree prediction, the system is continuously evolving. With the ability to process up to eight laser signals simultaneously, the NLWS is remarkably robust, experiencing only one known failure despite years of operation.

Naval Laser Warning Systems for Spanish Navy

Just recently, Saab has secured a contract to supply the Spanish Navy with a Naval Laser Warning Systems. The contract marks an important milestone for us because this is a new customer, on a state-of-the-art vessel, for our latest laser warning technology. Under the terms of the contract, Saab will deliver the first Naval Laser Warning Systems in 2026, with ongoing annual deliveries thereafter. Notably, Saab will collaborate closely with Navantia, the esteemed international naval shipyard responsible for the construction of the F110 frigates, to ensure seamless integration of NLWS sensors onto the frigates' superstructure. The F110- class, the new multi-purpose frigate of the Spanish Navy will integrate industry 4.0 technologies and be the first Spanish naval programme designed to have a Digital Twin.

Deception and Defensive Measures

The integration of NLWS with other interfaces enables automatic deception and countermeasures once an enemy signal is detected. For instance, the system can emit a massive cloud of smoke to obscure the view of the platform from guided missiles. Remarkably, most guided weapons self-destruct when unable to identify a target. Therefore, this deceptive manoeuvre not only evades the attack but also renders the attacker's weapons harmless.

Enhancing Situational Awareness

Laser warning systems provide a critical advantage in situational awareness. Equipped with 16 sensors, the system offers comprehensive coverage. Even on a combat ship spanning 140 meters, only eight to ten sensors are required to achieve 360-degree observation. The compactness of the system is truly remarkable, fitting into just two suitcases. This portability allows for easy transport, installation, and live demonstrations, making it exceptionally user-friendly, especially for military personnel unfamiliar with the system. Furthermore, this simplicity extends to training, as users can grasp all key functions within three days without any prerequisite knowledge. Moreover, the feedback from customers continuously informs the system's development, ensuring its effectiveness and adaptability in diverse operational scenarios.

Insights from other domains

As the threat landscape evolves, so too must the technology that counters it. Saab draws on its expertise across domains to enhance the performance of the Naval Laser Warning System. And with each advancement, the system becomes more indispensable to naval operations. Looking ahead, Raubenheimer envisions even greater speed and efficiency in signal detection, ensuring that naval forces stay one step ahead of their adversaries. In an era where danger lurks from every direction, a reliable 360-degree warning system is not just an asset—it's a necessity.

In general, Saab also relies heavily on feedback from its customers and their individual challenges in development. "A system is only as good as its ability to meet the needs of the user", says Raubenheimer. In the vast expanse of the sea, where threats can emerge from the shadows, the Naval Laser Warning System stands as a beacon of safety, guiding naval forces through the fog of war.
