From Edge AI and GPS-Denied Navigation to Tactical IMUs, Position Sensors and Temperature Sensors – The Engineering Challenges Behind the Next Generation of Autonomous Combat Aircraft
For decades, discussions about advanced fighter aircraft focused on their engines, radar, weapons, stealth and aerodynamic performance.
But the next generation of combat aircraft introduces another variable that changes almost the entire architecture:
There may be no pilot in the cockpit.
That does not mean simply removing the ejection seat, closing the canopy and connecting a remote control.
An unmanned combat aircraft required to operate autonomously or semi-autonomously must perform some of the functions currently handled by pilots and ground crews: understand the state of the aircraft, monitor the mission, detect changes in its environment, respond to failures and changing operational conditions, and maintain the ability to operate even when communication with the operator is limited.
This represents a significant transition from Automation to Autonomy.
An automated system can receive a predefined route and execute it. An autonomous system must receive information from its sensors, understand how conditions have changed, and adapt its behavior according to the mission parameters.
This distinction becomes particularly important on the modern battlefield. Breaking Defense has described a trend toward unmanned systems performing more processing and decision-making through Edge AI, directly onboard the platform, allowing them to continue operating in environments where GPS or communications may not be continuously available.
In Israel, this direction is already becoming visible. The Israeli Ministry of Defense has established a dedicated AI and Autonomy Administration and, in 2026, described the widespread deployment of autonomous systems across multiple operational arenas. Israel Aerospace Industries has also unveiled OPAL-NG, incorporating Edge AI and intended, among other applications, for Manned-Unmanned Teaming and Collaborative Combat Aircraft – CCA.
All of this raises an interesting engineering question:
If the Aircraft Must Make More Decisions on Its Own – How Does It Know What Is Actually Happening to It?
An AI algorithm can analyze a radar image.
A computer vision system can identify an object.
A Mission Computer can determine that a change in flight path is required.
But before the aircraft can decide what to do, it needs reliable answers to much more fundamental questions:
What is my attitude?
How fast am I rotating?
What is my acceleration?
Did the control surface actually reach the position I commanded?
Is a particular actuator beginning to overheat?
Did the system that received a command actually execute it?
And can I still trust the data I am receiving?
In a manned aircraft, there is another layer inside this loop: the pilot.
A pilot can sense that something is not behaving normally. The pilot sees indications, feels changes in aircraft behavior, compares information from different systems and makes a decision.
In an autonomous aircraft, an increasing portion of that capability must be converted into data.
In other words:
The more we remove the human from the cockpit, the better the aircraft’s nervous system needs to become.
And that nervous system begins with sensors.
Cameras and radar tell the aircraft what is happening outside it.
But another layer of sensors must tell it what is happening inside.
The IMU tells the system how the platform is moving.
Rotary and linear position sensors provide feedback on the actual position of control surfaces, actuators and other mechanisms.
Temperature sensors allow the system to monitor the thermal condition of motors, electromechanical systems, electronics and power systems.
The electrical system itself must detect abnormalities, isolate faults and help prevent a localized failure from becoming a platform-level loss.
Each of these components is small compared with the aircraft.
Together, however, they create something much larger:
Machine State Awareness – the ability of the machine to know its own state at any given moment.
And that is one of the fundamental requirements for meaningful autonomy.
Because autonomy does not begin with the decision.
It begins with the quality of the information on which that decision is based.
