SIPRI's arms production project monitors, describes and analyses trends and developments in arms production world-wide. The project was initiated in 1989 to study developments in the arms industry. It collects information on the major arms-producing companies and describes and analyses their adjustment to the changed economic and political context and the resulting changes in industrial structures. The amount of available information on the level of arms production is limited, both at the company and national level and there is a great need for further transparency.
The project maintains the SIPRI Arms industry database, which gives information on the 100 biggest arms and weapons-producing companies in the world. The data is released in annual data launches and is described in the SIPRI Yearbook.
