Largest European Defense Companies by Market Capitalization

A total of 27 European companies appear on SIPRI’s Top 100 arms-producing companies list, with the bulk of them headquartered in France, Germany, Italy, Sweden, and the United Kingdom. The European defense industry is highly dispersed — a few large publicly traded firms sit alongside roughly 1,350 small and medium-sized enterprises.

These companies cover a wide spectrum of military capabilities:

• Military aeronautics: BAE Systems (LSE) contributes to both the Eurofighter Typhoon and the F-35 Lightning II program, while Airbus Defence & Space produces the A400M Atlas military transport aircraft.
• Land systems & ammunition: Germany’s Rheinmetall is a leading producer of armored vehicles — including the Lynx and Boxer infantry fighting vehicles — along with advanced munitions and air defense systems.
• Naval & submarine platforms: Sweden’s Saab has over 100 years of experience building submarines and also manufactures the Gripen fighter jet.
• Defense electronics & cybersecurity: Thales (Euronext Paris) specializes in radars, avionics, satellites, and cybersecurity, while Safran — formed through the 2005 merger of SNECMA and SAGEM — produces aircraft engines, navigation systems, and missile propulsion.
• Helicopters & unmanned systems: Italy’s Leonardo is a world leader in military helicopters and unmanned aerial vehicles, and participates in the Global Combat Air Program (GCAP) alongside BAE Systems and Mitsubishi Heavy Industries.
• Propulsion & engines: Rolls-Royce (LSE) is the world’s second-largest maker of aircraft engines and maintains major defense-related businesses in marine propulsion.

Ownership structures in this sector reflect its strategic nature. In many cases, national governments hold blocking or controlling shares to safeguard alignment with defense priorities. Family-controlled enterprises also play a role — Dassault, for example, remains nearly 70% owned by the Dassault family. Cross-border collaboration is common: MBDA, a multinational missile systems company founded in 2001, is jointly owned by BAE Systems, Airbus, and Leonardo.
