Indra is showcasing satellite communications, electronic warfare systems and navigation radars currently used by several leading navies. These include forces from Spain, Germany, Norway, Portugal, Italy, India and South Korea.
The company’s technologies are designed to improve situational awareness and operational effectiveness. They also support submarines in modern multi-domain operations.
Ana Belén Buendía, Head of Indra’s Naval Business Unit, said: “our systems enable superior situational awareness and intelligence-gathering capabilities and prepare submarines to act as key assets in modern multidomain operations, while simultaneously enhancing their stealth and survivability.”
At the exhibition, Indra will display a submarine sail model integrating its systems across multiple masts. The design focuses on maintaining performance while reducing size and improving robustness.
Particular emphasis is placed on the TSUB 40 satellite communications suite. The system offers variants across X, Ka and Ku bands and includes three-axis pointing capability to ensure a stable and secure data link.
The TSUB 40 system is certified for use with the Spainsat NG satellite. It is also prepared for certification with the Wideband Global SATCOM constellation.
Indra is also presenting the iKeeper iS20 navigation radar. This silent, solid-state radar operates in X band and offers low probability of intercept.
The radar supports both standard and continuous wave modes. It provides surface surveillance and navigation support with high resolution.
The company is also highlighting its Full Digital electronic warfare systems. These systems, including the PEGASO family, provide early warning, surveillance and detection capabilities.
They feature broad electromagnetic spectrum coverage and advanced analysis tools. Artificial intelligence is used to process data and improve detection, identification and tracking performance.
Indra is additionally presenting simulation systems for crew training and mission preparation. These systems are designed to replicate operational environments with a high degree of realism.
The company is also showcasing maintenance services for naval systems. These services comply with NATO requirements and aim to maximise availability and extend platform life.
Rafael Arcos, Senior Manager at Indra, will present research on seabed control and maritime security. He said the focus is on achieving comprehensive situational awareness from the seabed to space and enabling autonomous threat detection and response.
Indra is involved in European research programmes such as SMAUG. These initiatives aim to advance capabilities in maritime surveillance and security.
The company’s technologies are integrated into a range of submarine platforms worldwide. These include classes such as S70, S80, U209, U214, U212, Kilo and KSS III.
Indra stated that its presence at UDT reflects its role across multiple defence domains. The company continues to develop systems for both surface ships and submarines for international customers.
