Denmark Considers Reactivation of Coastal Defence with NSM Batteries

Published on April 18, 2025, by Robin Häggblom

In a move reflecting the increasing focus on coastal defence, Denmark is contemplating the reactivation of its coastal missile capabilities using the Norwegian Kongsberg Naval Strike Missile (NSM) system. This decision comes amid the broader context of rearmament observed globally, notably in response to recent security challenges.

Historical Context of Coastal Defence in Denmark

During the Cold War, coastal anti-ship missile systems were commonplace among several nations. However, following the Cold War's conclusion, many countries, including Denmark, gradually retired these systems. Denmark previously operated mobile missile batteries equipped with Harpoon launchers, adapted from decommissioned Peder Skram-class frigates. These truck-mounted systems were part of a Mobile Missile Battery unit until their disbandment in 2003. The situation shifted in 2022 when Denmark leveraged this existing expertise to support Ukraine amidst escalating tensions due to the invasion by Russia. Denmark donated a mobile Harpoon battery to bolster Ukraine's coastal defenses, particularly around the critical area of Odesa.

New Developments in Danish Defence Strategy

Following recent announcements regarding a significant investment in the Royal Danish Navy, discussions surrounding the reactivation of coastal missile defence have gained traction. Reports from Danish newspaper Berlingske indicate that plans are in motion to acquire a mobile solution featuring the NSM.

The Danish Agency for Procurement and Logistics (DALO) has yet to confirm specific details regarding this procurement, citing ongoing negotiations that are expected to conclude after Easter. According to DALO spokespersons, "DALO can neither confirm nor deny information from leaked drafts of the final agreement."

Strategic Importance of the NSM

The NSM, which Denmark has already selected to replace ship-based Harpoons, aligns with the strategic needs of the country. With Denmark located at the entrance to the Baltic Sea, establishing effective coastal defence systems is essential. The War in Ukraine has underscored the value of such capabilities, especially in enhancing littoral defence.

The NSM's proven effectiveness in various coastal systems around the world, including use by the United States Marine Corps and Polish Maritime Missile Units, strengthens the case for Denmark. The Polish model, which features several truck-mounted missiles arranged in batteries, is likely to serve as a reference for Danish planning.

Conclusion

As Denmark continues to evaluate its defence posture, the potential reactivation of coastal missile defence with NSM batteries marks a significant step. This initiative not only reflects the evolving security environment in Europe but also emphasizes Denmark's commitment to safeguarding its territorial waters. The upcoming months will be crucial as negotiations finalize and details emerge about Denmark's coastal defense strategy.
