The LANZA radar family is Indra's Spanish L-band 3D air-surveillance and air-defense radar line, built around modular solid-state hardware and software-configurable operating modes. The family spans fixed long-range LRR sites, deployable LTR-25 radars, medium-range LTR-20 coverage, dual-use 3D PSR air-traffic-control radars, and LANZA N naval installations, with public Indra material tying newer LANZA radars to Spain's NATINAMDS-linked air-surveillance network and NATO deployable radar coverage.
LANZA is best read as a modular sensor family rather than a single fixed radar. Indra's 2019 family sheet describes shared solid-state L-band radar architecture, pencil-beam operation with electronic elevation control, distributed and redundant critical elements, and software-configurable exploration modes that let each configuration be adapted for different operators and sites.

Direct public Ukraine sourcing identifies the LTR-25 model rather than every LANZA configuration, so this family page links the published LTR-25 record instead of broadening family-level conflict claims.

Indra public material presents LANZA as a family rather than a single radar model, with variants for fixed long-range surveillance, deployable long-range coverage, medium-range mobile coverage, civil-military air-traffic control, and naval air warfare.
| Variant | Configuration | Designation notes |
|---|---|---|
| LANZA LRR | Fixed long-range early-warning radar | Indra describes LRR as a long-range model with up to 256 nautical miles of instrumented range and a backbone early-warning air-defense mission. Sources: Indra LANZA Radar Family |
 | Deployable long-range radar | Indra describes LTR-25 as the latest-generation deployable long-range LANZA model and NATO DADR-classified radar; the linked catalog record covers the Ukraine-destined LTR-25 conflict-use case. Sources: Indra Air Defence Radars, Indra FIDAE 2026 |
| LANZA LTR-20 | Mobile medium-range radar | Indra's family brochure lists LTR-20 as a medium-range tactical radar with selectable 200, 120, or 60 nautical mile instrumented range configurations for air-defense and gap-filler coverage. Sources: Indra LANZA Radar Family |
| LANZA 3D PSR | Dual-use civil and military air-traffic-control radar | Indra's family brochure identifies the 3D PSR branch as an en-route and approach ATC radar with 150 or 100 nautical mile instrumented range configurations. Sources: Indra LANZA Radar Family |
| LANZA N | Naval air-warfare radar | Indra's LANZA family brochure identifies LANZA N as the naval air-warfare configuration, with 180, 120, or 60 nautical mile instrumented range configurations; Indra and Tata later described Lanza-N commissioning aboard an Indian Navy warship.
