Lockheed Martin NetSense Uses 5G to Detect Unauthorized Drones

This article is based on an official press release from Lockheed Martin Corporation.

Lockheed Martin has unveiled a new prototype system that leverages existing commercial 5G cellular networks to detect unauthorized drones. According to an official press release from the company, the technology, dubbed NetSense™, is designed to identify aerial intrusions in crowded and complex environments without the need for traditional radar or camera systems.

As small uncrewed aerial systems (sUAS) become increasingly common in both civilian and conflict zones, detecting them in dense urban settings or near event venues has proven difficult. Lockheed Martin’s approach turns everyday cellular infrastructure into a real-time drone detection layer, offering a novel solution to a growing security challenge.

The rapid development of the NetSense system highlights a shift in defense contracting toward faster, more agile innovation cycles. Built in a matter of months by the company’s 5G.MIL® team, the project demonstrates how commercial technology can be rapidly adapted for critical safety and situational awareness applications.

How NetSense Turns 5G into a Sensor Network

Cell networks constantly exchange radio frequency (RF) signals with connected devices, creating an invisible field of waves that stretch, compress, and reflect as they interact with the physical environment. When a new object, such as a consumer drone, enters this RF field, it causes observable changes in the signal patterns.

According to the Lockheed Martin release, NetSense utilizes artificial intelligence to interpret these RF disruptions. The system translates the complex data into immediate, actionable cues, allowing users to determine if an object is in the airspace and track its trajectory. Notably, the system successfully detected a small drone that was not connected to the cellular network during a recent demonstration.

To visualize this data, the NetSense team integrated Lockheed Martin’s newly launched STAR.UI™ software. This interface features built-in AI agents that help operators monitor mission-relevant data in real time, serving as the visualization component of the broader STAR.OS™ modular architecture.

Rapid Innovation and Real-World Applications

The development of NetSense represents a departure from traditional, multi-year defense procurement timelines. Lockheed Martin noted that its 5G.MIL team operated much like a startup, utilizing small teams, rapid iteration, and tight feedback loops to prove the concept quickly.

“As a project concept in a new innovative space, we had more questions than answers as we started the project,” said Amir Stephenson, director of 5G.MIL Programs at Lockheed Martin.

Because the system relies on existing 5G towers and off-the-shelf mobile devices acting as receivers, it eliminates the need for specialized hardware or lengthy installation processes. The company emphasized that the technology is designed to maintain the privacy of commercial 5G users while providing an added layer of security.

The potential applications for this technology span multiple sectors. Lockheed Martin highlighted that stadiums could use the system to monitor restricted airspace during major events, while cities and port authorities could track drones navigating between buildings or shipping lanes. Additionally, schools could leverage the network to alert local law enforcement of unexpected drone activity.

AirPro News analysis

The introduction of NetSense underscores a broader industry trend of dual-use technology, where commercial infrastructure is repurposed for defense and security missions. By utilizing the ubiquitous nature of 5G networks, Lockheed Martin is addressing one of the primary limitations of traditional counter-UAS (C-UAS) systems, the high cost and logistical burden of deploying dedicated sensors across vast urban landscapes.

We observe that this “situational awareness as a service” model could significantly lower the barrier to entry for civilian organizations seeking drone detection capabilities. However, the reliance on commercial cellular networks will likely require ongoing collaboration with telecommunications providers to ensure seamless integration and address any potential regulatory or privacy concerns.

Frequently Asked Questions

What is Lockheed Martin’s NetSense system?

NetSense is a prototype drone detection system that uses existing commercial 5G cellular networks and artificial intelligence to identify unauthorized drones in complex environments.

How does the 5G drone detection work?

The system monitors the invisible field of radio frequency (RF) waves created by cell networks. When a drone enters the area, it disrupts these waves. NetSense uses AI to interpret these changes and alert operators, even if the drone is not connected to the network.

Does NetSense require new hardware to be installed?

No. According to Lockheed Martin, the system uses existing 5G towers and off-the-shelf phones as detection receivers, avoiding the need for new sensors or long installation timelines.
