Spain has transferred the Lanza LTR-25 radar to Ukraine to strengthen air defence

Ukraine has received the Lanza LTR-25 radar from Spain, which enhances the air defence’s ability to detect massive Russian air attacks in advance. This is not just about a new piece of equipment, but about a change in the very logic of sky protection – with increased response time and defence coordination.

The transfer of the radar is part of a broader shift in Spain’s policy regarding support for Ukraine. The Spanish publication Xataka reports on the radar handover.

Madrid has taken a step that some key allies hesitated to take for a long time – providing not only interception means but also critically important "eyes" for the air defence system. The shortage of long-range sensors has long been one of the main bottlenecks of Ukrainian air defence.

The LTR-25 radar, developed by Indra, has already been tested in NATO systems on the Alliance’s eastern flank. It is capable of detecting a wide range of threats – from drones and cruise missiles to ballistic targets and low-observable aircraft. Its detection range exceeds 450 kilometers, allowing Ukraine to receive warnings about air strikes much earlier.

How the Lanza Radar Works

The LTR-25 operates in the L-band, uses a phased array antenna, and employs digital beamforming. This enables it to track hundreds of targets simultaneously, even under conditions of active electronic warfare. This feature is particularly significant for detecting Shahed drones and cruise missiles, which Russia uses to overload Ukrainian air defences.

Another key advantage is mobility. The radar is adapted to the "turn on – detect – relocate" tactic, reducing the risk of destruction by Russian strikes on command and reconnaissance assets. Additionally, the system seamlessly integrates with Ukraine’s existing Patriot, SAMP/T, IRIS-T, and NASAMS complexes, acting as an efficiency multiplier for them.

Political and Strategic Context

The transfer of the LTR-25 demonstrates Spain’s new role – transitioning from a cautious partner to a supplier of critically important defence technologies. According to Xataka, Ukraine has received from Madrid the very long-range detection capabilities it had previously sought unsuccessfully from the United States due to political constraints.

Furthermore, the radar supply fits into a larger package of military and financial aid to Ukraine, publicly supported by Spanish Prime Minister Pedro Sánchez. If the LTR-25 proves successful in use, cooperation with Indra could evolve into a long-term partnership, strengthening the European component of Ukrainian air defence.

The Lanza LTR-25 is not just another radar. It is a tool that changes the depth of defence, giving Ukraine time and space for maneuver while reducing the effectiveness of Russian air attacks. In a war of attrition, such "invisible" changes often prove decisive.
