Indra is presenting at the BACSI 2026 Exercise —scheduled for 18 and 19 March
at the Albacete Air Logistics Centre as part of the Connected, Sustainable and Smart Air Base programme—
four use cases featuring cutting-edge systems for the sustainment of aerial platforms, inflight 5G
connectivity, new modes of pilot–fighter interaction and enhanced counterdrone capabilities. In addition, the
company will demonstrate its NIMBUS combat cloud, a revolutionary technology that will radically change
the way air forces operate and will be decisive for achieving true multidomain capabilities.
Of the five areas defined in the BACSI exercise organised by the Spanish Air and Space Force, Indra is
contributing key solutions to four of them: digitalised maintenance, 5G connectivity applied to aircraft,
advanced pilot–aircraft interaction systems and counterdrone defence systems.
Aircraft sustainment: mixedreality remote assistance In the field of sustainment, Indra will showcase its remote assistance system based on mixed reality goggles
(holographic glasses). This system is designed to enable operators and mechanics to connect with remote
experts, share realtime video and receive guidance or annotations during interventions. Tools of this kind are
particularly useful in international missions, where immediate access to specialists may be limited.
The system is aligned with the PERAM framework, which serves as the regulatory standard for military
aircraft maintenance and is comparable to EASA regulations in civil aviation. This alignment ensures
adherence to the safety and certification requirements that are characteristic of such operations.
The aircraft as a node in the logistics ecosystem
Another capability Indra will be presenting at BACSI is the application of 5G connectivity to aerial platforms,
with a particular focus on transmitting maintenance data during flight. This pioneering functionality enables
technical information to be sent to ground crews before landing, streamlining resource preparation and
improving logistical decisionmaking.
To achieve this, a C101 aircraft has been fitted with antennas and an onboard modem developed by Indra.
Ground tests using satellite connectivity have been successfully completed, and inflight trials are planned.
The solution combines 5G network connectivity with satellite communications, allowing for the transmission
of logistics or platformstatus data during operations.
These capabilities pave the way for more efficient aircraft sustainment management by integrating the
aircraft into the logistics cycle in nearreal time. This is stateoftheart technology that positions Indra at the
forefront, leading its development globally.
Fighter aircraft and neurotechnology
BACSI 2026 will also serve as a platform to showcase advances in physiological monitoring and multimodal
cockpit interaction. Indra is working on integrating biometric sensors, eyetracking systems and interaction
technologies that make it possible to analyse variables related to cognitive load and pilot status during the
mission.
A flight simulation cockpit will be displayed at the stand to demonstrate this proof of concept. These
technologies aim to explore new forms of interaction between pilots and onboard systems, capable of
adapting to the operational context and contributing to more efficient information management in complex
missions.
Counterdrone defence with an integrated view of airspace
In the field of drone defence, Indra is participating in a use case developed jointly with the Spanish Air and
Space Force that integrates its CUAS CROW system with crewed (ATM) and uncrewed (UTM) air traffic
management information.
A command-and-control post has been deployed during the exercises, combining data from Indra’s
counterdrone system sensors with air traffic information managed by ENAIRE through Uspace services. This
integration provides a unified picture of crewed and uncrewed traffic within the airport environment.
This capability makes it possible to distinguish authorised flights from potential threats, reduce false alarms
and improve coordination of the response to dronerelated incidents. The exercise features different
operational scenarios with cooperative and noncooperative uncrewed aircraft, as well as participation from
the State Law Enforcement Forces. Additional associated capabilities, such as the Nemus radar and the
SmartEar V3 RF sensor, will also be showcased during BACSI.
Combat cloud for multidomain operations
In addition to the defined use cases, Indra will conduct a demonstration of its combat cloud based on
NIMBUS nodes—a technology already tested in several pioneering flights in Europe and presented to the
Spanish Air and Space Force as part of the experimental and validation capabilities Indra maintains in
Galicia.
This combat cloud architecture enables sensors, platforms and decision centres to be connected within a
common network that facilitates secure realtime exchange of operational information and far more advanced
and precise decisionmaking. Solutions of this kind are essential for multidomain operations and for the
development of future nextgeneration air systems.
Indra has become a pioneer in developing this system in Europe and globally. This technology will, in the
coming years, completely transform military aviation, the way fighter aircraft operate and the role of the pilot.
