European defence, aerospace and security contractor delivering technology-led systems across land, air, maritime and cyber domains for government buyers.
Governments and armed forces need complex military capability delivered at national scale, from combat aircraft and warships to cyber defences, on programmes that run for decades. BAE Systems builds these systems through long-term government contracts, combining its own engineering workforce with partner suppliers across combat ships, submarines, fighter aircraft and defence electronics.
Unlike the larger United States primes Lockheed Martin, RTX and Northrop Grumman, it anchors its business in European and NATO procurement while spanning every operating domain from maritime shipbuilding to counter-drone systems. That breadth and home-market access position it as Europe's largest defence contractor and the European anchor among Western primes.
