Indra to Supply AESA S-Band Radar Components for Spanish Navy F110 Frigates

Indra has signed a contract with the U.S. company Lockheed Martin to supply the main components of the AESA (Active Electronically scanned Array) S-band radar antenna of the Spanish Navy’s future F110 frigates.

The value of the contract amounts to over €150 million and will last for 7 years.

Lockheed Martin’s Vice President & General Manager of the Integrated Warfare Systems and Sensors line of business, Paul Lemmo, and Indra’s Executive Director of Transportation and Defence, Ignacio Mataix, sealed the agreement at an event held at Navantia’s headquarters in Madrid, Spain. The signing of the agreement was immediately preceded by the signature of Lockheed Martin’s contract with Navantia to equip the Spanish Navy’s five F110 frigates with S-band radars, as well as the Integrated Ground Systems Center (CIST) in which the system will be tested.

It was announced earlier this month that Lockheed Martin’s solid state S-band radar, designated by the U.S. military as AN/SPY-7(V)1, was selected to equip the Spanish Navy’s five new F-110 multimission frigates. The contract was signed with the builder of the frigates, Navantia. The contract is also for the installation of the radar at Navantia’s land-based test site, Centro de Integración de Sistemas en Tierra (CIST).

This subcontract signed with Indra is within the framework of Lockheed Martin’s S-band Radar contract and will supply the critical elements to support the digital transmission and reception of each of the radars elements. This is the first of the contracts that Indra expects to be awarded during the construction phase of the five frigates to equip them with the sensors that their built-in mast carries.

The S-band anti-air warfare (AAW) radar is one of the ship’s key sensors and will give it supremacy and a dominant edge in combat. The radar is also one of the sensors that will make this frigate one of the most advanced of its kind in the world.

It is a fully digitized system composed of hundreds of small independent blocks or tiles. Its flat facets laid out around the mast minimize the ship’s radar profile. Thanks to these digital tiles, this system will be able to operate as if it had several radars working simultaneously, which gives it its multitasking capability. It may, for example, operate as a long-range radar and integrate missile control, as well as setting tracking on multiple targets.

Indra leads the development within the F110 Program of some of the most advanced sensors that will be available in the international market in the coming years. In addition to the aforementioned tiles for the S-band radar, Indra is developing:

+ The 25X Prisma Radar: whose mission is surveillance of the surface and low-altitude aerial targets.
+ The IFF System: which will identify allied from enemy aircraft and will have an integrated ADS-B surveillance system that will give support to air control in international missions.
+ Electronic defence systems: which will track the communications band and the radar band. They will detect and identify any vessel, submarine or nearby aerial or land platform, allowing the ship to circumvent multiple threats simultaneously
+ IRST i110: which will provide protection capacity against sea-skimming missiles or swarms of vessels, which typically attempt to impact the waterline of ships. It is a system on which Indra is working in conjunction with Tecnobit.
