Royal Air Force Takes Delivery of Indra Lanza LTR-25 Deployable Long-Range Air Defense Radar

The UK Royal Air Force (RAF) took delivery of Indra Lanza LTR-25 (Long Tactical Range 25) deployable long-range air defense radar.

Now the radar has arrived in the UK, it will undergo extensive trials and is due to be accepted into service with the RAF by mid-2021. The new state-of-the art radar can be deployed in support of worldwide operations or used to cover gaps in coverage on UK home shores.

Last year, the UK Ministry of Defence (MoD) Defence Equipment & Support (DE&S) Air Defence and Electronic Warfare Systems (ADEWS) team based at RAF Henlow awarded a £13.1 million contract to Spanish company Indra to produce their Lanza LTR-25 radar for the RAF’s Battlespace Management Force which controls the UK Air Surveillance and Control System (ASACS).

Due to its small number of components, this LTR-25 radar system can be rapidly deployed worldwide using RAF’s in-service military vehicles and transport aircraft such as the C-130J Hercules tactical airlifter. The radar also benefits from being highly capable of mitigating the effect of windfarms and can rotate at two different speeds providing an Air Traffic Radar Service mode long desired by the RAF.

The radar will be used mainly for long range surveillance of co-operative (secondary surveillance) and non-co-operative aircraft. The flexibility of the system means that the RAF will be able to carry out a variety of Battlespace Management Missions, including long and short term deployments worldwide, as well as gap-filling in the UK in response to national operational requirements.

Indra Lanza Radar LTR-25

The LTR-25 is a state-of-the-art, full solid-state three dimensional (3D) long range radar developed by Indra, which incorporates years of experience together with the latest technological advances.

The system also includes an Identifier Friend or Foe and Secondary Surveillance Radar (IFF/SSR), capable of providing target identification through interrogation and automatic processing of transponders replies in modes 1, 2, 3/A, C, 4, S and 5. The LTR-25 integrates a 3D Primary Surveillance Radar (SR) based on a pencil beam architecture which provides long range coverage.

The main function of the SR is the detection of non-cooperative aircrafts within the instrumented coverage volume, even under adverse conditions, including clutter and ECM environment. Target coordinates provided by the LTR-25 include target altitude (3D position).

The LTR-25 has been designed as a tactical deployable radar, with the capability of being transported by a variety of means, (road, rail, air or sea). All the LTR-25 associated equipment is completely integrated, so that all operative, transportable and deployable capabilities of the system are maintained.
