Future of US CBRN Defense Market: 2025–2035 Forecast and Opportunities

The landscape of national security and emergency preparedness in the United States is undergoing a subtle but significant transformation, driven by rising concern over chemical, biological, radiological, and nuclear threats. The latest report from MRFR puts the value of the US CBRN Defense Market at USD 3.88 billion in 2023, with projections showing growth to USD 8.0 billion by 2035 — a compound annual growth rate (CAGR) of about 5.37%. This projected expansion signals a mounting focus on CBRN defense capabilities, as government agencies, defense contractors, and civil-security stakeholders brace for emerging risks.

Central to this US CBRN Defense Market Growth is increasing investment by defense and homeland security agencies. Firms like Raytheon Technologies, General Dynamics, BAE Systems, Sierra Nevada Corporation and others are playing a pivotal role in supplying next-generation detection systems, protective gear, decontamination tools, and integrated response platforms. The emphasis is not just on conventional defense, but on building a layered, resilient infrastructure capable of handling everything from chemical warfare to biosecurity incidents.

Within the market, the chemical defense segment remains the largest due to ongoing concerns over chemical warfare agents, industrial chemical hazards, and potential attacks involving toxic chemicals. Meanwhile, growing attention to biological threats — following recent global health crises — has increased demand for biological defense solutions. The radiological and nuclear segment, though smaller, retains strategic importance given the catastrophic consequences of nuclear or radiological events. This wide threat coverage has spurred demand across detection, protective equipment, and decontamination and containment solutions.

Another dimension shaping the market is a shift toward sophisticated detection and monitoring technologies. According to broader CBRN/CBRNE market analyses, detection systems account for a dominant share of demand globally.  For the U.S., this means growing procurement of advanced sensors, real-time monitoring networks, portable detection kits, and fixed installation systems — all designed to identify chemical, biological, or radiological threats rapidly and reliably. Protective wearables, decontamination gear, and simulation-based training further round out the suite of CBRN capabilities, making for a comprehensive defense posture.

Looking ahead to 2035, the forecasted market value of USD 8.0 billion indicates robust, sustained demand for CBRN defense solutions. With evolving geopolitical dynamics, continued threat of non-state actors, and growing public awareness around biosecurity and radiological hazards, the expansion of the U.S. CBRN defense market seems inevitable. For policymakers, defense contractors, and civil-defense agencies, this implies a long-term commitment to technological innovation, preparedness, and multi-layered defense strategies.
