Denmark has ordered Rheinmetall’s MASS naval decoy system for its ABSALON-class and IVER HUITFELDT-class frigates in a contract worth a double-digit million-euro amount. A separate supply agreement lasting up to 21 years will allow the Royal Danish Navy to replenish its MASS stocks.

The procurement also covers systems for the Royal Danish Navy’s Weapons School and a quantity of Omnitrap-ER decoys. Deliveries are scheduled to begin in the fourth quarter of 2027, with the main contract value to be recognised in Rheinmetall’s second-quarter 2026 figures.

“The past few months have demonstrated the outstanding role played by the Danish Navy in NATO’s maritime defence in the Baltic Sea, the North Sea and also in the Arctic,” said Hauke H. Bindzus, CEO of Rheinmetall’s Business Unit Protection Systems. “Against this backdrop, we are particularly grateful that we have now also been able to convince the Danish Navy of the superiority of our MASS system as a soft-kill protection system for its frigates.”

Denmark becomes the 18th country to operate MASS, according to Rheinmetall. The company said more than 400 decoy launchers are currently in service worldwide.

“With this order from Denmark, every Scandinavian navy now has the Rheinmetall MASS launcher in service. Denmark becomes the 18th country to use this technology,” Bindzus said.

MASS is designed to protect naval vessels against threats including anti-ship missiles and laser-guided weapons. Rheinmetall said the system can be used in open-water, shallow-water and riverine operations.

The system deploys multispectral decoys covering radar, ultraviolet, electro-optical, laser and infrared wavelength ranges. It is intended to counter threats using different sensors and guidance technologies through a single soft-kill architecture.

Rheinmetall said MASS has a modular design that allows installation on vessels ranging from offshore patrol ships to frigates. It can be integrated with existing command and weapon-control systems or operated as a stand-alone system.

The Danish order extends MASS across all Scandinavian navies and adds a long-term replenishment mechanism for the Royal Danish Navy. The procurement also strengthens Denmark’s soft-kill protection capability for frigates operating in NATO maritime areas including the Baltic Sea, North Sea and Arctic.
