LANZA LTR-25 is a Spanish Indra deployable long-range 3D air-surveillance radar used to extend air-defense warning, tracking, and command-and-control coverage. Spain approved manufacture and supply of an LTR-25 for Ukraine in January 2026, while Indra describes the model as part of NATO's deployable radar component and in service with Ukraine's armed forces.

Radar Role

The LTR-25 is a sensor and air-picture asset rather than a missile launcher. Its conflict relevance comes from extending early warning, target tracking, and command-and-control inputs for other air-defense weapons.

Service Context

Public official material places the LTR-25 in allied deployable air-surveillance service before the Ukraine contract. Indra described NATO, Spanish, and United Kingdom users for the deployable LANZA DADR/LTR-25 branch, while NATO public reporting documented deployable radar coverage added in Romania in 2024.

Ballistic-missile tracking

Indra reported that the deployable LANZA DADR completed NATO tactical-ballistic-missile detection and tracking tests in 2022.

Ukrainian sources identify Iskra as the enterprise behind ST-68U/19Zh6 development history and later 35D6/36D6M modernization, while open technical references describe the 36D6 as an S-band radar with 360-degree azimuth coverage, four beams, 350 kW peak transmitter power, and target-data output to automated air-defense users. In the 2014 Russia-Ukraine War, visually documented loss lists, WarSpotting entries, and General Staff-derived reporting place 36D6/ST-68U radars on both Russian and Ukrainian sides of the air-defense fight, including repeated Russian radar losses in occupied Crimea.
