SUMMARY

For Ukrainian air-defense units, the biggest challenge is not always having enough missiles to intercept incoming threats. Some crews say the harder problem is having enough equipment to detect, identify and track Russian aircraft, drones and missiles before they reach their targets. The shortage highlights a less visible part of modern warfare: air defense depends on an entire chain of sensors, communications, radar and weapons working together.

THE HIDDEN SHORTAGE IN UKRAINE'S AIR DEFENSE — When discussions turn to Ukraine's air-defense needs, the focus often falls on missiles.

Missiles are expensive, limited and essential for intercepting Russian drones, cruise missiles and other aerial threats.

But for some Ukrainian air-defense crews, the shortage that creates the biggest operational problem comes before the missile is ever launched.

It is the equipment needed to find the enemy.

A Ukrainian air-defense sergeant has described target-detection equipment as one of the most difficult shortages facing his unit.

The problem highlights an important reality of modern warfare: having an interceptor missile is useless if a military cannot reliably detect and track the object it needs to shoot down.

Air Defense Starts With Detection

An effective air-defense system is much more than a launcher and a missile.

The process begins with detection.

Radar systems, sensors and other surveillance equipment must identify an approaching aircraft, drone or missile.

That information then has to reach the appropriate command and air-defense unit quickly enough for personnel to determine whether the object represents a threat.

Only after the target has been detected and tracked can an interceptor be assigned.

That makes surveillance equipment a critical part of the entire system.

If the detection layer is weak, even a well-stocked missile launcher can struggle to protect a city, military position or critical infrastructure.

The Growing Importance of Sensors

Russia's use of drones and missiles has made detection increasingly complicated.

Modern attacks can involve multiple types of weapons arriving from different directions and at different speeds.

Some drones fly relatively slowly and at low altitude.

Cruise missiles can move much faster and may follow routes designed to make interception more difficult.

Other aerial threats can attempt to overwhelm defensive systems by arriving in large numbers.

That creates a demanding requirement for Ukrainian air-defense crews.

They need to know what is coming, where it is coming from and where it is going.

Why Finding the Target Can Be Harder Than Shooting It

The logic appears simple: detect the threat, launch a missile and destroy it.

In reality, every stage can fail.

A radar may not have the ideal coverage.

A target may be difficult to distinguish from other objects.

Communications can be disrupted.

The information reaching an air-defense crew may arrive too late.

And an incoming attack can involve multiple targets simultaneously.

This is why air-defense warfare increasingly resembles a contest between networks rather than individual weapons.

Russia's Drone Campaign Adds Pressure

One of Ukraine's biggest air-defense challenges has been Russia's extensive use of relatively inexpensive drones.

Large drone attacks can force Ukrainian forces to monitor huge numbers of aerial objects simultaneously.

The economics can be difficult for the defender.

Using a highly expensive interceptor against a comparatively inexpensive drone may not always be sustainable.

But allowing the drone through could result in damage to civilian infrastructure, military facilities or energy systems.

Ukraine therefore needs multiple layers of defense, including radar, electronic warfare, mobile air-defense units and different types of interceptors.

The Equipment Behind the Missile

The equipment used to detect and track threats can take many forms.

  • Air-surveillance radar
  • Target-tracking systems
  • Electro-optical sensors
  • Command-and-control equipment
  • Communications systems
  • Mobile surveillance platforms
  • Electronic-warfare systems
  • Other battlefield sensors

These systems create the information needed by air-defense operators.

The more accurate and timely that information is, the better the chances of responding to an incoming threat.

Mobile Systems Are Particularly Valuable

Ukraine's air-defense forces also need equipment that can operate in different locations.

Mobility is important because fixed positions can become targets themselves.

Mobile radar and surveillance systems can potentially be moved to protect different areas or to avoid becoming predictable targets.

That creates another logistical challenge.

The military needs not only the equipment but also vehicles, power supplies, trained personnel, spare parts and secure communications to keep the systems operating.

The Information War in the Sky

Modern air warfare is increasingly an information battle.

The side that detects an incoming threat first gains valuable time.

Even a few minutes can determine whether an air-defense unit has enough time to respond.

This is particularly important against fast-moving missiles.

For slower drones, early detection can allow defenders to choose a less expensive method of interception instead of immediately using a sophisticated missile.

That can preserve high-end interceptors for threats that require them.

Missile Stocks Still Matter

The emphasis on detection equipment should not be interpreted as meaning that Ukraine has no missile shortage.

Interceptor missiles remain one of the most important components of Ukraine's air-defense network.

Advanced systems require specialized ammunition, and replacing those interceptors can take time.

Ukraine therefore faces two related problems.

It needs enough weapons to destroy incoming threats.

And it needs enough sensors and surveillance systems to identify those threats before it is too late.

The shortage of one component can undermine the effectiveness of the other.

The Cost of Modern Air Defense

Building an effective air-defense network is extremely expensive.

It requires a combination of hardware, software, trained personnel and continuous maintenance.

Radar systems themselves can cost millions of dollars.

Advanced interceptors can be even more expensive.

That creates a difficult strategic calculation for countries supporting Ukraine.

Providing additional missiles is important, but supplying the surveillance and command systems needed to use those missiles effectively can be equally important.

Training Is Another Constraint

Equipment alone does not solve the problem.

Air-defense operators need extensive training to interpret radar information, identify threats and coordinate responses.

They also need experience operating under pressure.

A large-scale attack can produce an enormous amount of information in a short period.

Operators must determine which objects are genuine threats and which may not require an expensive interceptor.

That requires judgment as well as technology.

Electronic Warfare Changes the Battlefield

Another complication is electronic warfare.

Modern militaries can attempt to interfere with communications, navigation systems and other electronic signals.

That means air-defense units cannot assume that every sensor will always work perfectly.

They need systems that can continue operating even when parts of the electronic environment are disrupted.

This increases the value of having multiple sources of information rather than depending entirely on one radar or sensor.

Ukraine's Air Defense Is a Layered System

Ukraine's defense against aerial attacks relies on multiple layers.

Different systems are intended to deal with different threats and distances.

Long-range systems can provide protection against some high-value threats, while shorter-range systems and other technologies can deal with drones and lower-flying objects.

Mobile teams can also operate closer to areas being protected.

The effectiveness of the overall system depends on these layers being connected.

The Economic Problem of Drone Warfare

The increasing use of inexpensive drones creates another major challenge.

An attacker can potentially launch large numbers of relatively cheap systems.

The defender then has to decide how to destroy them without exhausting expensive interceptors.

This has encouraged greater interest in lower-cost methods of countering drones.

Electronic warfare, guns, specialized anti-drone systems and other technologies can potentially complement traditional surface-to-air missiles.

But those systems still depend on detection.

Again, the chain begins with finding the target.

Why the Sergeant's Complaint Matters

The observation from the Ukrainian air-defense sergeant reveals something that is easy to overlook when examining the war from outside.

Military capability is not simply measured by the number of missiles sitting in storage.

A modern air-defense network is an ecosystem.

If radar coverage is insufficient, if communications are unreliable or if tracking equipment is unavailable, the effectiveness of the entire system can suffer.

That means military aid must address the complete architecture of defense rather than focusing on one highly visible component.

The Challenge for Ukraine's Allies

For countries supporting Ukraine, the issue creates a complicated procurement question.

Should additional resources go toward interceptors, radar systems, electronic warfare equipment, mobile sensors, communications infrastructure or training?

The answer is not simply one of these.

Ukraine requires a combination of capabilities.

But the experience of Ukrainian air-defense crews suggests that detection and tracking equipment deserves much greater attention in discussions about air-defense assistance.

Technology Is Changing the Nature of Air Defense

The battlefield is becoming increasingly dependent on sensors and data.

Drones can collect information.

Satellites can provide surveillance.

Radar can identify objects at distance.

Electronic systems can detect signals.

Command networks can combine information from different sources.

The result is an increasingly interconnected battlefield where information can be as valuable as ammunition.

What Happens Next?

Ukraine's need for air-defense equipment is unlikely to disappear as long as Russia continues conducting aerial attacks.

The challenge will be maintaining enough capacity to protect cities, infrastructure and military positions over the long term.

That means replacing missiles, repairing radar systems, training operators and expanding surveillance coverage.

It also means developing cheaper ways of dealing with inexpensive drones so that sophisticated interceptors can be reserved for the most dangerous threats.

Conclusion

The Ukrainian air-defense sergeant's warning highlights a critical part of modern warfare that can easily disappear behind discussions about missiles and launchers.

You cannot effectively destroy a target that you cannot detect and track.

Ukraine therefore needs more than additional interceptors.

It needs the sensors, radar, communications systems and trained personnel that allow those weapons to be used effectively.

As drone warfare becomes more widespread and aerial attacks become increasingly complex, the ability to see the battlefield may become just as important as the ability to strike it.

For Ukraine, that makes the equipment that finds the enemy one of the most strategically important shortages in the air-defense fight.
