On 27 May 2026, the Rijksoverheid announced that the Netherlands would increasingly collaborate with other European countries on the development and procurement of military equipment by joining OCCAR. The government said the move would enhance European defence cooperation and offer new participation opportunities for the Dutch defence industry. According to the same announcement, OCCAR’s membership would stand at seven states and the organisation managed 24 cooperative armament projects.
The Rijksoverheid described OCCAR as a framework for European partners to run joint development and procurement efforts, with the intent of pooling requirements and coordinating complex programmes. By entering OCCAR, the Netherlands positioned itself to align future capability plans with partners through established multi‑nation project structures managed by the organisation.
This step followed a broader pattern of European collaboration in which the Netherlands has participated. In April 2026, Germany, Denmark, Sweden and the Netherlands tested drones to protect subsea data cables and pipelines during the SeaSEC 2026 activity near Warnemünde, the Bundeswehr reported. In parallel, NATO has pursued interoperable, digitally enabled training tools, including a shared AI‑supported workbench for exercises, according to NATO Allied Command Transformation.
The decision also sat within a week of wider allied security moves. On 27 May 2026, the United Kingdom published a bilateral security and defence partnership treaty with Poland that addressed challenges posed by the Russian Federation and reaffirmed NATO commitments, as HM Government set out. Together, these actions indicated a tightening European focus on coordinated capability development and collective defence planning across procurement, training and operational protection of critical infrastructure.
