Netherlands to Join OCCAR as Seventh Member State — Both Chambers Approve the Accession The Hague Shelved in 2002
Bonn, 20 October 2026
Key points
- The Netherlands is to become the seventh member state of OCCAR, the organisation that manages European cooperative armament programmes, on 1 January 2027, it was announced at OCCAR's 25th-anniversary event at the Petersberg near Bonn on 20 October
- The Tweede Kamer, the lower house, passed the bill approving the OCCAR Convention and the OCCAR Security Treaty (36952) without a vote on 10 September; the Eerste Kamer adopted it and notified the lower house on 6 October
- The Hague tabled an accession bill in 2001 and a year later asked parliament to stop handling the bill, after several parties doubted OCCAR's "global balance" between contributions and industrial work would favour Dutch industry; the 2001 bill was withdrawn when the new one was tabled in May 2026
- Membership costs about EUR 1.5 million a year net; OCCAR runs 28 programmes worth about EUR 8.5 billion a year, and the Netherlands already takes part as a partner in three of them, the Boxer among them
- Stéphane Kammerer of France's DGA succeeds Joachim Sucker as OCCAR's director in February 2027
The Netherlands is joining the organisation it declined to join in 2002.
OCCAR was founded by France, Germany, Italy and Britain; Belgium and Spain joined later. The Netherlands received its invitation in February 2025, and the convention enters into force for an acceding state thirty days after its instrument of accession is received. The government's case to parliament is influence and access: more influence over programmes OCCAR is preparing in which the defence ministry is interested, and a chance for Dutch firms to work on OCCAR projects the Netherlands does not join. The Boxer is the reference case: bought with Germany since 2006 under OCCAR project management, 200 Dutch vehicles delivered by 2020, and an OCCAR contract for 72 more signed in October 2025. The government had aimed to accede in 2026; the anniversary event gave the first day of 2027.
The question that stopped Dutch accession in 2002 will be answered in reports the Dutch parliament cannot read. OCCAR reports to member states on the global balance, the long-run match between what each pays and the work its industry wins, and those reports are confidential. Asked by the PVV and CDA parties for periodic briefings, even confidential ones, the government replied that it cannot change the arrangements alone and will ask partners after accession whether abstracted data could be shared with parliament in confidence. Its argument that defence-industrial prospects are "entirely different" from 2002 may be right; the balance is a place it could be shown. The first test after 1 January is whether the Tweede Kamer receives any global-balance figure at all.
