The SIPRI Arms Industry Database contains information on arms-producing and military services. It includes public and private companies, but not manufacturing or maintenance units of the armed services. The database contains financial data and employment data for arms-producing companies in the OECD and developing countries (except China) based on open sources. Sources include company annual reports and articles in journals and newspapers. Estimates of arms sales are made on the basis of open information.
The SIPRI Arms Industry Database was initiated in 1989. At that time it excluded data for companies in Eastern European countries, including the Soviet Union. However, the current version contains data from 2002, including data for companies in Russia.
