Revealed: World's top 10 defence companies

The original 'SIPRI Top 100' lists the world’s 100 largest arms-producing and

military services companies (excluding Chinese companies), ranked by

their arms sales in 2011.

The list is based on the comprehensive SIPRI Arms Industry Database, which contains financial and employment data on the world’s major arms-producing and military services companies.
