Air defense systems market seen reaching $78.2 billion by 2031

The global air defense systems market is projected to grow from $46.2 billion in 2021 to $78.2 billion by 2031, driven by cross-border conflicts, defense spending and newer threats such as drones. North America led the market in 2021, while Asia-Pacific is expected to post the fastest growth through 2031. Why it matters: - Air defense systems are becoming more central as governments respond to cross-border conflicts, drones and other modern threats. - Rising defense budgets are helping offset the high upfront cost of these systems and supporting deployment across more platforms. - The market’s projected climb to $78.2 billion by 2031 signals sustained demand for missile defense modernization. What happened: - Air defense systems market size was valued at $46.2 billion in 2021. - The market is projected to reach $78.2 billion by 2031. - The market is expected to grow at a 5.6% CAGR from 2022 to 2031. - Allied Market Research released the report June 17, 2026. - The report covers components, range, platform, type and region. The details: - The market is driven by rise in cross-border conflicts, technological advancements in weapon systems and use of newer weapons, including drones. - Growth is also supported by a global surge in defense budgets. - High costs remain a constraint on adoption. - Development of next-generation air and missile defense systems is expected to create new opportunities. - Internet of things adoption is expected to alter market dynamics during the forecast period. - AI-powered systems such as Iron Dome are identified in the report as a major example of the shift toward smarter interception. - The report says Iron Dome is reportedly 90% effective. - AI and machine learning can help process large volumes of missile-testing data, including ground-based midcourse defense tests that generate terabytes of information. - Market participants are focusing on product launches, contracts and partnerships to meet changing end-user needs. - The component segment includes weapon system, fire control system, command and control system and others. - The range segment includes short-range, medium-range and long-range air defense systems. - The platform segment includes ground, naval and airborne. - The type segment includes missile defense system, anti-aircraft and counter rocket, artillery and mortar system. - The regional split includes North America, Europe, Asia-Pacific and LAMEA. - Global defense spending reached $1,981 billion in 2020, up 2.6% year over year, according to Stockholm International Peace Research Institute. - Military expenditure accounted for 2.4% of global GDP in 2020. - The report cites THAAD, Iron Dome and S-400 as examples of widely adopted missile defense systems. - North America held nearly one-third of the global market in 2021. - Asia-Pacific is forecast to post the fastest CAGR at 6.3% through 2031. Between the lines: - The report points to a market shifting from basic air defense toward integrated, software-driven systems. - AI, ML and IoT are emerging as differentiators because they improve target identification, data analysis and response speed. - The regional outlook suggests mature procurement in North America and faster capability building in Asia-Pacific. - The presence of large defense contractors across the competitive set indicates a consolidated market with heavy reliance on government contracts. What’s next: - Governments are likely to keep investing in air and missile defense as threats diversify. - New product launches and defense contracts should remain a key growth lever for suppliers. - Asia-Pacific spending is expected to be a major focus area as countries strengthen regional defense networks. - The report is available as a sample and for purchase through Allied Market Research.
