BAE Systems is the UK's largest defence company and one of the world's top five defence contractors — manufacturing fighter jets, naval vessels, armoured vehicles, electronic warfare systems and cyber security solutions for NATO and allied nations globally. The European rearmament cycle that began with Russia's Ukraine invasion in 2022 significantly expanded BAE's order pipeline across all segments.
Why Defence Spending Drives BAE Systems
BAE Systems' revenues are split across four segments: Electronic Systems (US-focused), Platforms & Services (vehicles and munitions), Air (Typhoon, F-35 components), and Maritime (nuclear submarines, Type 26 frigates). This diversification means BAE benefits from both the UK's own defence spending and from US and international programmes — making it less dependent on any single NATO member's budget than purely European peers like Rheinmetall.
BAE's nuclear submarine programme (Astute class, AUKUS SSNX) provides particularly stable, long-duration revenue — submarine contracts run 15–20 years and are essentially immune to short-term political cycles.
The 2022–2025 Defence Cycle: +103% in 46 Months
BAE Systems traded at GBp 680 in February 2022. By December 2025 it reached GBp 1,380 — a gain of 103% in 46 months. This underperforms Rheinmetall (+767%) and Saab (+193%) in percentage terms, reflecting BAE's larger size and more diversified revenue base. However, in absolute return terms, BAE delivered one of the FTSE 100's best performances of the period.
BAE vs. Rheinmetall — Different Rearmament Exposures
Rheinmetall benefits primarily from European land warfare rearmament (ammunition, tanks). BAE benefits from maritime rearmament (nuclear submarines, frigates) and aerospace (Typhoon upgrades, F-35 components). Investors seeking pure European rearmament beta choose Rheinmetall; investors seeking diversified NATO exposure with US programme upside choose BAE.
Key Risks
BAE's main risks are UK government austerity (which could affect domestic contracts), execution risk on complex programmes (submarines are notoriously difficult to build), and the AUKUS programme's dependency on UK-Australia-US political alignment. Currency risk (substantial USD revenues reported in GBP) is also a factor.
