For decades, ground forces relied on a simple assumption: keep moving and you stay alive. That logic no longer holds.

According to Tobias Lehmann, Product Manager Command and Control at Rheinmetall, the threat picture from the air has changed so radically that it is forcing armed forces worldwide to rethink how they fight, maneuver, and defend themselves. What was once dismissed as a marginal, asymmetric danger has become a decisive factor on the modern battlefield.

“What used to be a fringe threat can now wipe out mechanized formations within minutes,” Lehmann explains. The drivers of this shift are well known—but their combined impact is unprecedented: FPV drones, swarm tactics, hypersonic weapons, and new forms of electronic resilience such as fiber‑optic control links that are largely immune to jamming.

Cheap Attack, Expensive Defence

Perhaps the most disruptive element is economics.

An FPV attack drone today can cost less than a set of tires for a mid‑size car, yet deliver precise and lethal effects. At the same time, traditional air‑defence systems remain expensive, limited in numbers, and often optimized for very different threat profiles.

This imbalance has strategic consequences. “Mobility no longer protects,” Lehmann says. What was once a covered relocation is now “a target with coordinates.” Persistent sensors, ubiquitous drones, and real‑time data sharing have turned movement itself into a vulnerability.

From Guns to Systems

These changes are also reshaping air defence.

Classical point‑defence systems, designed to operate largely in isolation, are reaching their limits. What is required now are networked solutions that fuse sensors, command‑and‑control, and effectors in real time.

Rheinmetall’s response is exemplified by its Skyranger air‑defence turret. “This is no longer a gun in the classical sense,” Lehmann says. “It is a digital effector.” The decisive factor is not just firepower, but how seamlessly the system is embedded into a larger defensive architecture.

At the heart of that architecture lies Skymaster, Rheinmetall’s command‑and‑control software. Skymaster aggregates sensor data from multiple sources—organic sensors as well as external radars—into a single, shared air picture. Threats are automatically evaluated and assigned, with the goal of reducing the time between detection and engagement to mere seconds.

Interoperability as a Requirement

A defining feature of modern air defence is interoperability.

Armed forces no longer want closed systems from a single vendor. “Customers want to mix and match,” Lehmann notes—radars from one manufacturer, effectors from another. Rheinmetall has therefore designed Skymaster and its air‑defence portfolio around an open system architecture, allowing new sensors, weapons, and capabilities to be integrated quickly.

This flexibility is critical in a threat environment that evolves faster than traditional procurement cycles. Systems must be upgradable, adaptable, and scalable—without requiring a complete redesign every time the threat changes.

A Fundamental Shift in Defence Thinking

For militaries, the implications are profound.

The future of short‑range air defence is not defined by individual platforms, but by speed, data fusion, and system‑of‑systems thinking. The ability to detect, decide, and act faster than the attacker is becoming the primary measure of effectiveness.

Rheinmetall’s facility in Zurich‑Oerlikon, home to its air‑defence expertise, is currently ramping up operations in response to this demand. The focus is no longer on single weapons, but on integrated defensive networks capable of dealing with mass, speed, and complexity.

In the new air‑threat reality, protection is no longer about armor or mobility. It is about information, connectivity, and seconds.

And those who cannot compress the kill chain fast enough may not get a second chance.
