The system, designed to equip next-generation European and allied naval vessels, is built around fully digital 4D AESA technology and is intended to provide advanced air and surface surveillance in demanding operational environments.
According to the company, the Prisma-S radar combines range, azimuth, altitude and target velocity information, supporting simultaneous anti-air warfare, anti-submarine warfare, and long-range target designation.
This multifunction capability, coupled with digital signal processing, enables more precise trajectory tracking and target designation in increasingly congested electromagnetic conditions.
In addition to the radar, Indra is using the event to present developments in multi-domain capability, specifically the NIMBUS combat cloud.
The company claimed that this is the first solution of its type to demonstrate performance in Nato naval exercises and was featured at REPMUS 26, enabling real-time connectivity and information sharing between ships, uncrewed surface vessels, and Indra’s TARSIS fixed-wing uncrewed aerial vehicle.
During the exhibition, Indra will also outline its approach to seabed surveillance, which it says is needed to help protect European gas pipelines, power and communications cables, and ports.
In addition,Top of Form Bottom of Formthe company will present a portfolio of systems designed to support submarine surveillance, connectivity, and stealth.
These include the iKeeper-iS20 navigation radar with standard and continuous wave operating modes, the TSUB-40 satellite communications system supporting multiple frequency bands and offering three-axis pointing capabilities, the PEGASO NG electronic warfare system for situational awareness and intelligence, and the company’s Identification Friend or Foe (IFF) system.
According to Indra, these systems are configured to meet the size, power, and pressure requirements of submarine operations.
