Counter-UAS Explained: What CUAS Means and Who Can Deploy It | Airsight
AI Analysis
The US counter-UAS market is rapidly expanding, projected to exceed $4 billion by 2026, with increasing authority delegated to state and local agencies via the SAFER SKIES Act. Federal agencies like FEMA, DHS, and TSA are actively investing in and testing C-UAS technologies, moving beyond a purely military focus. The standard operational framework for all C-UAS systems is Detect, Track, Identify, Mitigate (DTIM).
Key Takeaways
- Projected US spending on counter-UAS systems will surpass $4 billion in 2026.
- The SAFER SKIES Act grants counter-drone authority to state and local law enforcement.
- FEMA has allocated $500 million in grants for C-UAS detection equipment with full federal funding.
- The DoD has been developing C-UAS capabilities since the mid-2010s, fielding systems like LIDS (Army) and MADIS (Marine Corps).
- The DTIM (Detect, Track, Identify, Mitigate) framework is universally applied across all C-UAS systems.
Why It Matters
The proliferation of drone technology necessitates robust counter-UAS capabilities to protect critical infrastructure, public safety, and national security. Expanding authority to state and local agencies signifies a decentralized approach to airspace security, requiring interoperability and standardized procedures. The significant investment indicates a long-term commitment to addressing the evolving drone threat.

Counter-UAS Explained: What CUAS Means and Who Can Deploy It | Airsight
The United States will spend more than $4 billion on counter-UAS systems in 2026. The SAFER SKIES Act extended counter-drone authority to state and local agencies for the first time. FEMA launched a $500 million C-UAS grant program to fund detection equipment at 100% federal coverage. The DHS Science and Technology Directorate is testing cutting-edge counter-drone technologies at federal facilities. The TSA operates C-UAS test beds at Miami International and LAX. And a Congressional Research Service report now tracks DOD counter-UAS programs as a dedicated policy issue. Counter-UAS, once a military niche, is now a national security priority with active programs at every level of government.
If you are encountering the terms CUAS, C-UAS, counter-UAS, or counter unmanned aerial systems for the first time, you are not alone. These terms all refer to the same discipline, and the market around them is evolving faster than most organizations can track. This guide defines what counter-UAS means, explains the operational framework that every C-UAS system follows, maps who is authorized to deploy each capability tier, and helps you determine where your organization fits in this landscape.
What Does Counter-UAS Mean?
Counter-UAS (also written as C-UAS, CUAS, or counter unmanned aerial systems) refers to the technologies, systems, and procedures used to detect, track, identify, and mitigate threats from unauthorized unmanned aircraft systems. A UAS includes the drone itself (the UAV or unmanned aerial vehicle), the ground control station, and the communication link between them. A counter-UAS system is designed to detect the presence of a UAS in protected airspace and, where authorized, take action to neutralize the threat.
The term originated in military doctrine, where the DOD has been developing counter-drone capabilities since the mid-2010s in response to threats from weaponized commercial drones in Iraq, Syria, and other conflict zones. The Congressional Research Service documents that the DOD has fielded multiple counter-UAS systems, including the Army's Low, Slow, Small UAS Integrated Defeat System (LIDS) and the Marine Corps' Marine Air Defense Integrated System (MADIS), across all service branches.
Today, counter-UAS has expanded far beyond the military. The same technology framework applies to airports, correctional facilities, stadiums, critical infrastructure, and public safety agencies. The terminology is the same. The operational framework is the same. The difference is who is authorized to use which capabilities.
The DTIM Framework: How Every C-UAS System Operates
Every counter-UAS system, regardless of vendor, price point, or deployment context, follows the same four-phase operational framework: Detect, Track, Identify, Mitigate (DTIM). We covered the full DTIM workflow in a previous
