Indra Reveals Counter-Drone Details in Spain's €2 Billion Air Defence Modernisation Plan
Spanish defence technology group Indra has disclosed further details of its plan to modernise Spain's COAAAS semi-automatic air defence command centre at the Full Spectrum Air Defence (FSAD) event in London. The €2 billion programme will deliver 19 new SAMOC systems and the MTR-10 full-AESA multifunction tactical radar, with counter-UAS capabilities integrated into the overall air defence architecture.

Highlights
- Indra was awarded a €2 billion contract in 2025 by the Spanish Army to modernise the COAAAS semi-automatic air defence command centre.
- The programme includes the deployment of 19 new SAMOC systems integrated with Indra's AirDef C2 tactical command-and-control system, already operational at Spanish Air Force ARS centres.
- The new MTR-10 full-AESA multifunction tactical radar can transition from transport to operational status in under 5 minutes and fits an ISO 20 footprint compatible with standard logistics.
- Counter-UAS (C-UAS) capabilities have been explicitly integrated into the COAAAS upgrade, reflecting increasing drone threat prioritisation in Spanish air defence planning.
- Indra presented the COAAAS modernisation details at the Full Spectrum Air Defence (FSAD) event held in London.
Indra Reveals Counter-Drone Details in Spain's €2 Billion Air Defence Modernisation Plan
Spanish defence technology group Indra has provided further details on its upgrade of Spain's COAAAS (Semiautomatic Anti-Aircraft Artillery Operations Centre) at the Full Spectrum Air Defence (FSAD) event held in London, with a particular focus on next-generation air defence systems and counter-UAS (C-UAS) capabilities.
A €2 Billion Modernisation Programme
In 2025, the Spanish Army selected Indra to lead the COAAAS modernisation effort, with a total budget of €2 billion. The programme covers the deployment of 19 new SAMOC systems and the integration of next-generation sensors.
Dual-Core Architecture: AirDef C2 and the MTR-10 Radar
At a press briefing during the event, Indra outlined the two core elements underpinning the modernised COAAAS:
The Tactical Control Layer is built around Indra's AirDef C2 system, already operational at the Spanish Air Force's ARS air defence centres. This ensures seamless integration between the new SAMOC units and existing air defence infrastructure.
The Sensor Element introduces Indra's new MTR-10 Full AESA Multifunction Tactical Radar, which offers:
- Both rotating and static operating modes
- Improved tracking refresh rates against fast-moving targets
- Rapid deployment capability: ready for operation within 5 minutes of transport configuration
- An ISO 20 footprint, compatible with standard trucks and air logistics supply chains
These features make the MTR-10 particularly suited to fast-paced frontline deployment scenarios.
Counter-Drone Capabilities Integrated into the Framework
Indra placed special emphasis at FSAD on the tactical C-UAS component of the COAAAS upgrade, signalling that the Spanish Air Force is actively embedding drone threat response within its broader air defence architecture. This reflects the growing priority placed on countering the increasing threat posed by unmanned aerial systems on the modern battlefield.
