Kongsberg Finalizes Zone 5 Acquisition, Pairs JSM with Rusty Dagger for High-Low Cruise Missile Mix

Kongsberg Completes Zone 5 Acquisition

Norwegian missile-maker Kongsberg has finalized its acquisition of a majority stake in Zone 5 Technologies, bringing under its umbrella the U.S. start-up’s Rusty Dagger low-cost cruise missile, among others. The deal, first announced in December, sees Kongsberg now holding a 90 percent stake in California-based Zone 5, which will continue to operate as an independent subsidiary. The announcement was made at the ILA Berlin airshow, where officials from both companies detailed the strategic rationale and provided updates on the Rusty Dagger program.

High-Low Mix Strategy

With both weapons already moving into large-scale production, Kongsberg is making the case for combining its stealthy Joint Strike Missile (JSM) with the low-cost Rusty Dagger in operational scenarios. This tiered approach offers a high-low mix: the JSM provides advanced stealth and long-range precision for high-value targets, while the Rusty Dagger delivers cost-effective mass for saturation strikes. Thomas Akers, founder and CEO of Kongsberg, explained, “What we’re doing here is that we’re combining Kongsberg’s niche, exquisite technologies with a company very capable of designing for cost efficiency and mass production.”

Rusty Dagger Progress and Fighter Integration

Zone 5 has confirmed that the Rusty Dagger, which is already being supplied to Ukraine, is now cleared for use on four different types of fighter aircraft, including the F-16. This marks a significant expansion of the weapon’s operational flexibility. The missile is designed for rapid deployment and low cost, making it suitable for high-volume production and use in contested environments where affordability and numbers matter.

Zone 5 Technologies Background

Founded in 2011, Zone 5 is one of an emerging class of defense companies gaining prominence for developing low-cost, rapidly deployable capabilities. In many ways, they represent the inverse of traditional defense contractors, favoring speed, scalability, and cost efficiency over highly customized, high-priced systems. The acquisition allows Kongsberg to offer a broader portfolio that includes both premium and cost-effective strike options, particularly for the European market.

Implications for European Defense

Kongsberg executives noted that buying a stake in Zone 5 offered the fastest path to offering lower-cost missiles that still deliver meaningful combat capability, especially in terms of bringing these to the European market. The combination of JSM and Rusty Dagger provides NATO allies with flexible options for standoff strike, from high-end precision to massed salvos. As the war in Ukraine continues to demonstrate the value of both high-end and low-cost munitions, Kongsberg’s strategy positions it to meet diverse operational needs.

Looking Ahead

With production already underway for both missiles, Kongsberg and Zone 5 are poised to scale up deliveries. The Rusty Dagger’s integration with multiple fighter types, including the F-16, opens up a wide customer base. Meanwhile, the JSM remains a key asset for stealth platforms like the F-35. Together, they offer a comprehensive solution for modern standoff strike requirements.
