The Close-in weapon systems serve as the final layer of a ship’s defense, designed to neutralize fast-moving threats that slip past long-range interceptors. Their rapid reaction and automated operation allow them to respond in the seconds available before an impact.

The global close-in weapon systems market is witnessing strong growth as defense forces increasingly focus on protecting military platforms from rapidly evolving short-range threats. The market size is projected to reach US$ 17.51 billion by 2034, increasing from US$ 7.61 billion in 2025. The market is anticipated to register a CAGR of 9.70% from 2026 to 2034.

Close-in weapon systems are important defensive solutions deployed across land-based and naval platforms. The market is segmented by type into gun-based systems and missile-based systems. By platform, the market covers land-based and naval-based systems. Armament categories include 20 mm, 30 mm, 35 mm, 40 mm, and others. Technology segments include radar, active homing, passive homing, infrared, and other technologies.
