proposed in its 1966 report to establish an institute, later named the Stockholm International Peace Research Institute, SIPRI.

. The commission also recommended that SIPRI work is of "an applied research character directed towards practical-political questions
should be carried on in a constant interchange with research of a more theoretical kind". SIPRI has built its reputation and standing on competence, professional skills, and the collection of hard data and precise facts, rendering accessible impartial information on weapon developments, arms transfers and production, military expenditure, as well as on arms limitations, reductions and disarmament. The task of the institute is to conduct "scientific research on questions of conflict and cooperation of importance for international peace and security with the aim of contributing to an understanding of the conditions for peaceful solution of international conflicts and for a stable peace".

SIPRI's organisation consists of a Governing Board, Director, Deputy Director, Research Staff Collegium and support staff. An Advisory Committee serves as a consultative body to the institute. The Governing Board takes decisions on important matters concerning the research agenda, activities, organisation and financial administration of the institute. Other matters are decided by the Director. The Research Staff Collegium advises the Director on research matters. The staff of about 70 employees is mainly international, with 25 different nationalities reported in 2019. The researchers are recruited for specific project periods and represent various academic disciplines. SIPRI also hosts guest researchers who work on issues related to research programmes as well as interns in relevant fields whose programmes of study can contribute to and benefit from SIPRI's research. The institute works in a global network, with partnerships and cooperation between other institutes and with individual scientists. SIPRI has close cooperation with many multilateral organisations, for example, the
