Spain is gearing up for a high-tech leap in intelligence gathering, selecting Airbus and Indra to develop a small fleet of next-gen signals intelligence (SIGINT) planes.

Over the next 18 months, the companies will run a conceptual study to figure out the most suitable base aircraft and intelligence systems for the Spanish Air and Space Force.

Led by the Ministry of Defence, the program aims to deliver a platform that can detect, track, classify, and identify key targets, essentially giving Spain’s armed forces a high-tech “eye in the sky.”

Airbus will lead the aircraft design, while Indra will focus on integrating electronic and communications intelligence systems.

In a later phase, Airbus will modify the selected aircraft, install Indra’s proposed SIGINT system, and oversee overall production.

Picking the Backbone

Imagery suggests the Airbus A320 family is in the running, with the A321 variant emerging as the likely candidate.

This narrow-body, single-aisle aircraft combines medium-haul performance with lower operating costs, cruising at 540 miles (870 kilometers) per hour.

It also boasts an operational range of 5,950 kilometers (3,700 miles), enough to sweep across regional and continental airspace.

Powered by twin turbofan engines and operated by two pilots with cabin support, the A321 could serve as a capable “backbone” for Spain’s next-gen intelligence missions.
