SIPRI Yearbook 2022

I. Developments in arms transfers, 2017–21

Chapter:: 9. International arms transfers
Source:: SIPRI Yearbook 2022
Author(s):: Siemon T. Wezeman

The volume of International transfers of major arms in 2017–21 was 4.6 per cent lower than in 2012–16, but was 3.9 per cent higher than in 2007–11 and 30 per cent higher than in 2002–2006 when arms transfers were at their lowest volume for any five-year period since 1952–56 (see figure 9.1).¹ However, the total volume in 2017–21 was still around 35 per cent lower than the peak reached in the periods 1977–81 and 1982–86, at the height of the cold war.
