The rapid growth of drone warfare is reshaping Ground Based Air Defence (GBAD). Land forces need systems that can detect, track and respond to an increasing range of sophisticated aerial threats without requiring costly and operationally disruptive system overhauls.
This has necessitated a strategic shift from single-solution systems toward layered, upgradeable architectures that can be adapted over time to meet the latest threats and operational needs.
No one-size-fits-all
As aerial threats continue to evolve, no single sensor or effector can address the full spectrum of airborne challenges. Ground forces need protection from a range of threats, from small drones and loitering munitions to helicopters, fixed-wing aircraft and missile systems, in order to maintain freedom of action. These threats require different responses at varying ranges, while viewing them in isolation can also create vulnerabilities. Effective air defence therefore depends on the ability to detect, track and respond across the full threat spectrum.
This is particularly critical in land environments where platforms must operate across diverse terrain with varying threat profiles, from open plains to complex mountainous regions. Further compounding this is the operational climate, requiring capabilities that can operate reliably across harsh, dry environments and cold, wet and windy conditions.
Layered approach to air defence
Effective capability therefore requires a multi-layered approach combining surveillance, tracking and both soft- and hard-kill response options.
This need has driven a marked change in multinational programmes and organisation expectations, with demand for solutions that can be enhanced over time, not replaced, being of paramount importance. The ability to insert or upgrade sensors and tracking capability without disrupting the wider platform is now considered a key requirement for long-life GBAD systems.
Spiral development and open architecture solutions underpin this approach. Spiral development enables militaries and organisations to deploy capability quickly, then upgrade and adapt it as threats evolve and budgets allow. Vitally, it is open architectures that enable system upgrades and insertions as well as interoperability. At a multinational level, this is key to enabling collaboration and providing nations with the flexibility to enhance their capabilities at different speeds in response to the threat environment, rather than moving in lockstep.
Open architecture enables adaptation
The foundation of a GBAD capability is a solution that can be adapted throughout its lifespan in response to evolving threats and military need. Open architecture systems illustrate this approach and have been deployed in GBAD configurations. Open architecture allows payload modules to be replaced in the field without major redesign of the wider system, providing vital flexibility and reliability. This approach can also reduce through-life costs and maintenance demands, while improving availability by allowing modules to be upgraded or replaced individually. In turn, this reduces the risk of unplanned downtime and potential capability gaps.
Modularity also enables integration of emerging technologies including the latest AI-powered deep learning trackers and edge processors, to ensure the capability benefits from the latest innovations throughout its lifespan.
Robust and reliable targeting and tracking capabilities are critical enablers, particularly as new effectors such as directed energy weapons (DEW) continue to evolve. There will be a constant requirement for integration into existing system-of-system solutions without re-architecting the entire system.
Future-proofing GBAD
As aerial threats continue to diversify, land forces need GBAD systems that are layered, modular and open by design. The ability to integrate new sensors, trackers and effectors to counter evolving threats will be central to maintaining freedom of action, protecting deployed forces and ensuring that air defence systems remain operationally relevant throughout their service life.
