Military Aviation‭: ‬
When the Hunter‭ ‬Becomes the Hunted

For decades, military aviation has invested extraordinary effort in protecting aircraft from the threats we understood best. We learned to detect radar-guided missiles and developed warning receivers, electronic countermeasures, flares, chaff and increasingly sophisticated defensive aids suites. Aircraft survivability became an engineering discipline built around a familiar proposition: understand the threat, detect it early enough and defeat it before it reaches the aircraft. But the battlespace is changing faster than some of those assumptions. 

Today, a small uncrewed aircraft can fly low through terrain and urban clutter, approach from unexpected directions, operate with increasing autonomy and, in some cases, pursue an aircraft itself. The hunter can now become the hunted.

The economics, geometry and timelines of this threat are fundamentally different. A relatively inexpensive uncrewed system does not need to destroy an aircraft in a traditional air-to-air engagement to have operational effect. It can threaten a helicopter during hover or landing, force evasive action, damage exposed systems or create collision hazards. As speed, autonomy and coordinated routing improve, several uncrewed systems may eventually attack from different directions at once.

The question is no longer whether uncrewed aircraft will become an aviation survivability problem. They already are. The more important question is whether our thinking about aircraft protection can evolve as quickly as the threat.

The instinctive response is often to search for a new weapon. A laser perhaps. A high-power microwave. An interceptor. But after looking closely at the airborne counter-UAS problem, I believe that framing
is incomplete.

The hardest problem may not ultimately be firepower. It may be time. Before any defensive system can defeat a drone, the aircraft must detect it. The track must be correlated, the object classified, an engagement decision made, the defensive system cued and the threat engaged.

Find. Fix. Finish.

Against a small, fast-moving target emerging from terrain or clutter at short range, those steps become brutally compressed. A drone travelling at approximately 600km/h covers 10km in about a minute. At 2km, it may be only around 12 seconds away. Those 12 seconds are not merely weapon-engagement time. They contain the entire decision chain.

A weapon capable of defeating a target is of limited value if the aircraft cannot detect, classify, authorise and engage it within the available window. Aircraft survivability may therefore depend as much on decision speed as on weapon power.

High-energy lasers are understandably attractive. Once a target has been detected, tracked and locked, the effect travels at the speed of light and can concentrate energy with great precision. But a laser must generally remain on a vulnerable point long enough to produce the desired effect while aircraft may be manoeuvring. Weather, vibration and geometry matter, and one beam normally deals with one aimpoint at a time.

There is also the aircraft itself. A weapon-class laser requires power, energy storage, cooling and structural support, bringing weight, volume, drag and heat. The engineering question is therefore not simply: can the laser defeat the drone? It is: can the aircraft carry the capability required to defeat the drone and still accomplish its mission?

High-power microwave systems offer a different proposition. They can potentially address a broader sector and offer one-to-many engagement against susceptible unmanned systems. But targets may have hardened electronics, while the defending aircraft is itself full of electronics that must be protected from its own defensive system. There is no free technological advantage.

It is tempting to imagine that technology will eventually produce a single pod that can simply be attached to any aircraft and solve the problem. I call that conceptual destination the Panacea Pod.

No such panacea exists today. Nor should we expect every aircraft to require the same solution. Large fixed-wing aircraft, light aircraft and helicopters operate with very different margins of power, payload, cooling and geometry. This is why ‘laser or microwave?’ is the wrong question.

It is better to ask what combination of sensing, processing, decision-making and effects gives this aircraft the greatest probability of completing its mission in this threat environment.

Sometimes the answer may include a laser. Sometimes high-power microwave. Sometimes an interceptor.

The future architecture is more likely to be layered and modular than universal.

The future solution cannot simply bolt a new weapon onto an old survivability architecture. Sensing, processing, automation and effects must evolve together. And there is a principle I would place above every technology. The purpose of aircraft survivability is not simply to save the aircraft; it is to allow the aircraft to accomplish its mission.

Every kilogram of defensive equipment, every watt consumed and every additional unit of drag competes with payload, range, endurance and combat capability. At some point, a defensive solution can protect an aircraft so heavily that it compromises the reason we sent it into the battlespace. That is not survivability. That is mission failure by another route.

The measure of success must therefore be mission-preserving survivability. Technology will undoubtedly shift that balance. Sensors will become smaller and more capable. Artificial intelligence and autonomy will compress the find-fix-finish cycle. Directed-energy systems will become lighter and more efficient. Advances in energy storage and thermal management may make capabilities practical tomorrow that many aircraft cannot accommodate today.

But there may also be another path. Perhaps the next step is to stop thinking of aircraft survivability as something that must reside entirely within the aircraft. Some sensing, processing and defensive effects could increasingly be carried by other platforms operating as part of the same combat system. This suggests a different model: distributed survivability.

Protection becomes a property not simply of an individual aircraft, but of a team: crewed and uncrewed platforms, distributed sensors, autonomous processing and multiple effects working together. Instead of continually asking how much more protection can be placed on one aircraft, we may increasingly ask how survivability can be distributed across the force.

The history of military aviation is a history of adaptation. Every improvement has produced a countermeasure, and every countermeasure another adaptation. Uncrewed systems are accelerating that cycle. This is not simply a race between weapons: it is a race between learning curves.

The side that prevails may not be the one with the most powerful laser or the strongest microwave pulse. It may be the one that learns fastest how to connect sensing, decisions, effects and platforms into a survivability architecture that evolves as rapidly as the threat.

For generations, military aircraft were largely designed to protect themselves from weapons launched against them. We are entering an era in which the weapon may itself hunt the aircraft. When the hunter becomes the hunted, survivability must be reimagined, not around the aircraft alone, but around the team that keeps it in the fight.
