U.S. Threat Assessment: 16,000-Plus Foreign Systems Could Target America by 2035

More than 16,000 foreign delivery systems could be capable of targeting the United States by 2035, according to the 2026 Annual Threat Assessment of the U.S. Intelligence Community. That is up from roughly 3,000 today a fivefold-plus increase that would make homeland defense as much a capacity and systems-integration problem as an interceptor problem.

The figure does not mean 16,000 missiles are currently deployed against the United States. It is a projection covering a growing inventory of foreign delivery systems with the capability to reach or otherwise target the country. The unclassified assessment, prepared by the National Intelligence Council under the Office of the Director of National Intelligence, attributes that expansion to development by China, Russia, North Korea, Iran and Pakistan.

The more consequential detail is the projected mix. Foreign militaries increasingly plan to combine sophisticated long-range missiles with cheaper, expendable one-way attack drones, according to the assessment. For defenders, those categories create different sensing, tracking and response demands while competing for finite attention and interception capacity.

Volume changes the systems problem

A layered defense must do more than detect an object. Its sensors and command network have to establish and maintain tracks, distinguish relevant threats from other objects, assign an appropriate response and pass information between systems quickly enough to act. Increasing the number and variety of potential threats raises the processing and coordination burden at each stage.

That is why the projected rise cannot be evaluated simply by comparing the number of delivery systems with the number of interceptors. Geography, warning time, sensor coverage, system availability and the ability to connect data from different domains all affect defensive capacity. A low-cost drone and an advanced long-range missile also do not present equivalent technical problems or justify identical responses.

The assessment reportedly finds that the existing U.S. nuclear deterrent continues to safeguard the homeland. At the same time, it warns that precision-strike weapons, hypersonic systems, drones and dual-use technologies will make domestic airspace progressively more difficult to defend. Deterrence and active defense therefore remain related but distinct missions: one seeks to prevent an attack through consequences, while the other must detect and respond to systems that are already in motion.

North Korea has tested intercontinental ballistic missiles described as capable of reaching the entire U.S. mainland and continues flight testing and uranium enrichment as it expands its operational nuclear arsenal. Iran, meanwhile, has developed space-launch technology that could be adapted into a militarily viable intercontinental ballistic missile by 2035 if Tehran chooses that path, the assessment says. That finding is conditional rather than a declaration that Iran has fielded such a missile.

China and Russia remain the principal strategic drivers. Russia is modernizing its air-, land- and submarine-based nuclear delivery forces while pursuing additional systems intended to bypass existing interception networks. Chinese planners are focusing on counters to planned U.S. missile defenses, including Golden Dome for America.

Golden Dome’s integration test

Golden Dome is intended to connect persistent space-based sensing, multiple interceptor layers and integrated command and control. An April 2026 official program update said its initial architecture blueprint had been completed, a command-and-control consortium established and contracts awarded for critical components.

Initial large-scale tests concentrated on command-and-control software and connections among sensors and response systems. That focus matters because a broad homeland architecture will combine existing equipment with new technology developed by different military organizations and contractors. The Missile Defense Agency has been assigned an engineering, integration and test role, while capabilities it already developed are expected to feed into the wider architecture.

Open and modular designs may make it easier to add sensors, software and interceptors over time, but they do not eliminate the need for disciplined interface management, realistic testing and long-term maintenance funding. Reliability and life-cycle cost become more important when an architecture must remain continuously available rather than perform only during occasional demonstrations.

The 16,000-plus projection is therefore best read as a measure of scale and diversity, not as a count of missiles presently aimed at America. The defining engineering question through 2035 will be whether U.S. detection, tracking and command systems can expand coherently enough to manage many more potential threats without letting complexity outpace the architecture built to handle them.
