Indra Radar to Track Air and Sea Targets at Euronaval
Indra's Prisma-S AESA radar and NIMBUS combat cloud go on show at Euronaval 2026, with no published performance figures yet.
Updated on Nov. 2, 2026 in Cybersecurity
Spanish defence firm Indra is set to unveil its Prisma-S naval AESA radar at Euronaval 2026, running 3 to 6 November 2026 at Paris Nord Villepinte. The radar is described as an active electronically scanned array for naval air and surface surveillance, built on fully digital 4D AESA technology. The product is announced for showing at the exhibition; it has not been shown in operation in this source.
Why it matters
Naval radars that combine air, surface and submarine-warfare tasks in one array point to consolidated multi-role sensing on warships. Indra is also presenting its NIMBUS combat cloud, which links ships, uncrewed surface vessels and its TARSIS uncrewed aircraft, suggesting the sensor and networking layers are being developed together.
The source gives no measured specifications for the Prisma-S, so no performance figure can be reported against a baseline. It is described qualitatively as an active electronically scanned array combining range, azimuth, altitude and target velocity data.
The players
Indra
Spanish defence and technology company whose portfolio spans radars, satellite communications, electronic warfare systems and the NIMBUS combat cloud.
The details
The Prisma-S is an active electronically scanned array (AESA), a radar whose many small transmit-receive elements steer the beam electronically rather than by rotating an antenna. Its fully digital 4D design combines range, azimuth, altitude and target velocity in one picture. Digital signal processing, which turns received radar echoes into numerical data in software, is cited as enabling more precise trajectory tracking and target designation in crowded electromagnetic conditions. The radar is positioned for simultaneous anti-air warfare, anti-submarine warfare and long-range target designation.
Timeline
3 to 6 November 2026: Euronaval 2026 exhibition at Paris Nord Villepinte, France.
Euronaval 2026 is the 30th edition of the event.
The Tech Race
Indra is positioning the Prisma-S within the naval AESA segment, where digital multi-function arrays are replacing mechanically scanned radars on modern warships. The source does not name a specific competing program to compare against.
The Prisma-S and NIMBUS are shown at Euronaval 2026 with no availability, pricing or delivery timeline stated. Navies and defence buyers attending the 3 to 6 November exhibition are the audience most likely to evaluate them first.
The takeaway
Watch Euronaval 2026 from 3 to 6 November at Paris Nord Villepinte for Indra's first live presentation of the Prisma-S and NIMBUS, including any performance or delivery figures released there.
