The Impact of Artificial Intelligence on Military Defense and Security

AI is transforming nearly every industry, including military defense and security. It’s already enhancing capabilities in decision-making, operational efficiency, and threat mitigation.

DoD has developed many use cases, and defense contractors have multiple products in the development stage and in the field. There are two notable projects: the Replicator initiative and collaborative combat aircraft. Scheduled for an August 2025 deployment, Replicator is expected to include autonomous systems spanning multiple domains, and autonomous collaborative combat aircraft initiatives are intended to produce uncrewed aircraft capable of surveillance, reconnaissance, and dogfighting.

However, much more needs to be done.

The Impact of Artificial Intelligence on Military Defense Systems

AI and machine learning are changing warfare and defense, creating autonomous systems, and enhancing situational awareness with aided real-time decision-making.

AI-Powered Sensors and Sensor Networks

AI can improve government defense sensors and sensor-enabled kill webs by aggregating data across multiple sources simultaneously, identifying anomalies and potential threats, and triggering immediate alerts to personnel. This data can help predict field movements and adversary actions, giving field commanders deeper insight into possible strategies.

Autonomous Systems and Platforms

The use of AI in autonomous drones, ground vehicles, and naval systems is becoming more common. For example, autonomous surveillance systems can be used for border control and reconnaissance. Drone and autonomous platforms reduce human risk and operational costs.

Ukraine has become an “AI War Lab” for testing technology. In fact, Time dubbed it “The First AI War.” Dozens of AI-enhanced defense systems, including autonomous drones, targeting systems, and facial-recognition tools, are being tested on the ground.

Improving Military Decision-Making Through AI and Data Analytics

Another way that AI impacts military operations is by analyzing vast data sets to predict potential conflict zones or areas that require attention.

Advanced Analytics for Predictive Modeling

Predictive analytics in threat detection and resource allocation have significant roles in modern warfare and defensive capabilities. Applying AI to military systems fosters real-time decision-making in high-stakes situations, such as battlefield command and control.

The Strategic Studies Institute recently completed a two-year study, and it concluded that the military must prepare for large-scale operations that require rapid decision-making, which can only be achieved through the integration of advanced AI.

Cybersecurity and Defense Against Emerging Threats

Cyber warfare is becoming more frequent. NATO characterizes it this way: “Cyberspace is contested at all times, and malicious cyber events occur every day, from low-level to technologically sophisticated attacks.”

The same AI tools that are helping defend against attacks are being used by adversaries to scale hacking efforts. Nation-states are increasingly targeting defense infrastructure to disrupt systems and interfere with operational technologies.

AI-enabled cybersecurity tools for detecting anomalies and breaches and responding to cyberattacks proactively have become a high priority. Safeguarding military networks from cyber threats and adversarial attacks is critical, even during peace times. For example, the Cybersecurity and Infrastructure Security Agency used AI tools to eradicate the Volt Typhoon attack on critical infrastructure across multiple sectors, a crucial vector for national security.

Counterintelligence

AI is also helping to detect and neutralize espionage and fraud. For example, it analyzes communications and data patterns to identify and thwart enemy intelligence efforts.

The Integration of AI with Existing Military Infrastructure

Of course, integrating AI with existing military infrastructure presents challenges, as certain components have been in place for decades. A holistic approach is required to ensure seamless integration. That said, AI is already making a difference in key areas.

AI-Enhanced Communication Systems

Optimizing communication networks for military personnel enables seamless and secure data transfer. AI-managed communication systems allow for more efficient coordination during complex operations.

Maintenance and Logistics Optimization

Supporting personnel and materiel movement and maintaining operations are fundamental. AI is transforming logistics, predicting maintenance needs, and ensuring mission readiness. Anticipating demand and optimizing routing increases planning accuracy. Furthermore, preemptive maintenance, based on sensors and historical performance, helps avoid operational disruptions in the field.

"We want to fight with an unfair advantage," said Air Force Gen. CQ Brown, Jr. He points to lessons learned most recently in Ukraine, where logistics was not as interoperable as initially hoped, creating limiting factors. While AI is helping streamline data analysis and aid in decision-making for logistics and maintenance, communication and coordination still need to be improved.

Looking Forward: The Future of AI in Military Defense and Security

Emerging AI technologies like quantum computing can reshape military defense systems. A Congressional Research Service report shows various potential use cases, including:

1. Quantum Sensing: Offering enhanced capabilities, such as detecting underground structures, nuclear materials, and stealth submarines
2. Quantum Computers: Enabling significant advances in pattern recognition for autonomous weapons and cryptography, such as breaking current encryption methods
3. Quantum Communications: Facilitating secure communications via quantum key distribution to strengthen networking among quantum systems

Quantum computing recently took a major step forward. For example, in less than five minutes, Google’s Willow quantum chip performed a benchmark computation that would take today’s fastest supercomputer 10 septillion years—a number that exceeds the age of the universe. Such data analysis at rapid speed holds significant potential for defense initiatives.

Another frontier is the future integration of AI with space defense and hypersonic weapons. For instance, hypersonic missiles and glide vehicles travel at speeds exceeding Mach 5, making them difficult to intercept. AI provides faster detection of heat signatures for earlier warnings.

Leveraging AI for a Competitive Edge in Defense

The US military’s long-held technological overmatch is quickly eroding, so steps must be taken to regain the lead. “Preserving U.S. military overmatch requires an acceleration of AI development across the DoD,” said Col. Joshua Glonek, US Army.

The DoD, intelligence agencies, and contractors must explore opportunities for leveraging AI to maintain a competitive edge in national defense.
