The Danish Defence Acquisition and Logistics Organisation (Forsvarsministeriets Materiel- og Indkøbsstyrelse, FMI) has signed an agreement to procure the Blocker sea mine system from the Finnish defence and technology company FORCIT. The agency announced this on 5 November in a press release. The procurement is intended to strengthen Denmark's maritime defence and takes place within the Naval Mines Cooperation (NMC), in which Finland is the lead nation.
"With the acquisition of Blocker, we are strengthening Denmark's maritime defence and our ability to carry out tasks together with our allies. Through international cooperation, we can jointly acquire an important capability while also strengthening cooperation on materiel and operational requirements between countries," says Commander Steen Balslev, head of the maritime division at FMI.
According to the manufacturer, Blocker is a bottom mine with a target-seeking system and an explosive effect equivalent to more than 1,000 kilograms of TNT. According to FMI, sea mine systems can help protect Danish waters and support the defence's tasks. The press release does not state how many mines Denmark is purchasing or what the Danish share of the cost will be.
In addition to Denmark and Finland, Germany, Lithuania and Norway are taking part in the initial joint procurement of Blocker, which is led by Finland. On 25 June, FORCIT signed a framework agreement with the Finnish Defence Forces Logistics Command for deliveries to the five countries. The agreement is worth "hundreds of millions of euros," NDS reported in July. The procurement may eventually be expanded to include five additional countries.
According to Hannu Hytti, head of the naval unit at FORCIT, the framework agreement is based on a common Blocker configuration for all participating navies, which is intended to ensure interoperability and interchangeability. Each country will then develop its own algorithms based on its operational requirements.
The NMC was launched in 2024 and further developed through a framework agreement between the countries in 2025. Among other things, it is intended to support joint procurements and strengthen cooperation on logistics, training, exercises and the systems' service life. When NDS reported on the cooperation in October 2025, ten countries were taking part, including Sweden.
