At the NATO Technical Interoperability 2024 (TIE24) C-UAS exercise, the topic of directed energy weapons (DEWs), particularly lasers, and their use in C-UAS strategies was once again a key point of discussion.
One of the projects discussed was ‘Project Jupiter,’ which is a combined effort from Germany and the Netherlands, is said to be under development for integration with the GTK Boxer vehicle. The project aims to provide mobile, 360-degree laser coverage for countering hostile UAS.
Laser DEWs are widely considered as an answer to one of the greatest challenges involved with developing effective C-UAS strategies, as they tip the scales when it comes to cost-asymmetry. However, according to Lieutenant Colonel Reinout de Vries of the Dutch MoD, Project Leader for Jupiter, lasers are “an addendum, an additional tool in the toolkit of the commander. Nothing more, nothing less.” The broader conversation on laser DEWs often highlights their potential in counter-drone operations. Lasers can offer near-instantaneous targeting, with virtually limitless ‘ammunition,’ provided sufficient energy supply.
The increasing proliferation of drones, from commercial off-the-shelf models to advanced military systems, poses significant challenges to NATO forces and their allies. This has been particularly evident in the ongoing war in Ukraine, where drones have become one of the primary offensive tools applied by both sides. Exercises like TIE24 offer the opportunity for member states to explore innovative technologies, share best practices and collaborate on future solutions. As the defence landscape evolves, lasers will likely play an ever-growing role in counter-UAS strategies. However, they are not a one-size-fits-all solution. The future of defence lies in a layered, integrated approach, where technologies like lasers complement existing systems, ensuring a robust and adaptable response to emerging threats.
Their precision is another advantage, allowing the neutralisation of fast-moving, small aerial targets like drones. However, as de Vries noted at TIE24, while lasers bring significant advantages to the battlefield, they are not a standalone solution. Lasers have some key limitations, as they can struggle in adverse weather conditions, such as rain or fog, and require precise alignment with targets. These factors mean that lasers, though promising, are not a “silver bullet” for modern defence. Instead, they should be integrated into a broader, layered defence strategy. A holistic approach would combine traditional kinetic interceptors, electronic warfare and aerial drone-to-drone effectors to address a wide range of aerial threats effectively. The discussions around Project Jupiter align with NATO’s ongoing efforts to advance counter-UAS technologies.
