Defense & Security Systems Market Research & Consulting

Defense and security systems are bought against threats that change faster than procurement cycles: cheap drones now cost air defences more per interception than the drones themselves, navies are rearming for contested sea lanes, and critical sites need one control room that sees every sensor. This page brings together the Douglas Insights studies on those systems, sized from programmes, fleets and installed sites rather than from vendor revenue alone, so buyers can see which spending is locked into multi-year budgets and which depends on the next threat. The largest market covered is integrated air and missile defence, worth USD 39.9 billion in 2025 and analysed in the Integrated Air and Missile Defence Systems Market study, where interceptor stocks run out long before launchers do. Naval combat systems follow at USD 23.0 billion, military training and simulation at USD 17.9 billion and electronic warfare at USD 17.2 billion. Growth sits with uncrewed systems and the defences against them: the Anti-Drone Market grows 22.4% a year, military unmanned ground vehicles 12.9% and military drones 10.1%. On the civil side, the Physical Security Information Management (PSIM) Market study covers the software that unifies security at airports, utilities and cities. Every study carries its build receipt, regional split and scenario bands to 2035.
