The NSPO ASB has the authority to establish subordinate bodies of experts comprising national representatives to provide technical support and assistance in carrying out ASB's duties. Particularly, the ASB is assisted by the Logistics (LOG) Committee and the Finance, Administration and Audit (FAA) Committee, established to review technical logistics and finance related topics. The two Committees advise and assist the ASB by making recommendations and endorsements for ultimate ASB decision. Working groups may be established by the Board or by the Subordinate Committees as consultative bodies for specific tasks.
Multinational Programmes are established within NSPO following recommendation by the ASB, in consultation with the CNAD for NATO Armament Procurement Programmes, and approval by the North Atlantic Council. Multinational Programmes are governed trough a dedicated governance structure, which consists of a Programme Board (PB), directing the execution of the Programme and retaining full autonomy with regard to the requirements, priority settings and financial management.
The Central Europe Pipeline System (CEPS) and the NATO Airlift Management (NAM) are the two Multinational Programmes currently established within NSPO. Two separate Annexes within the NSPO Charter lay out specific provisions and responsibilities for both programmes.
Support or Procurement Partnerships may be established within the NSPO on the initiative of two or more NATO nations wishing to organise in common the support and services of activities within the scope of the NSPO's mission. NSPO currently comprises 31 Support Partnerships , reporting to the ASB for approval of any decision of principle before measures are implemented within the NSPO.
Both Multinational Programmes and Support or Procurement Partnerships constitute an integral part of the NSPO and share in the juridical personality of NATO.
The NSPO may also conclude, subject to an advance approval in principle by the NAC, agreements or contracts involving a non-NATO Nation and agreements with an international organisation. Particularly, the NSPO ASB is authorised to conclude agreements on support cooperation with Nations that have received authorisation from the NAC to contribute to a NATO-led operation or Nations that have a partnership programme with NATO, such as such as Partnership for Peace, Mediterranean Dialogue and the Istanbul Co-operation Initiative.
