Defence

Technology for a safer world

Strategic partner in European defence programs and national sovereignty

We believe in the importance of advancing sovereign, technologically robust capabilities to protect society. Our role in defence focuses on developing high-value systems across land, air, sea, space and cyberspace. With decades of experience and a strong industrial vocation, we design and deliver critical systems for missile guidance, electronic warfare, command and control, and autonomous platforms — all tailored for modern and future combat environments.

We are active contributors to programs such as FCAS/NGWS, Eurodrone, PAZ 2 and SpainSat NG. Our participation reinforces European strategic autonomy and strengthens Spain’s technological sovereignty. We lead the development of systems that ensure operational superiority, such as guidance units, active antennas and autonomous navigation platforms.

Defence innovation for strategic autonomy

At Sener, we develop critical defence technologies across land, air, sea, space, and cyberspace. From missile guidance to autonomous systems, we support European strategic autonomy with scalable, certifiable solutions. Our combat-proven systems integrate communications, navigation and control for today’s and tomorrow’s missions — ensuring operational superiority and national resilience.

Why choose us

We integrate the entire life cycle of our systems: design, engineering, manufacturing, testing, qualification and logistical support. Our recognized centers of excellence in actuation and control for missile systems have made us a trusted partner in Europe’s most ambitious defence initiatives. Our systems are combat-proven, exportable and ready for integration into NATO and allied frameworks.

More than 1,000 deployed systems across air, land and naval platforms

Our electromechanical and RF systems have been integrated into guided missiles such as METEOR, Taurus KEPD 350, RBS 70 NG, PAC 3 MSE and IRIS-T. Our extensive experience enables us to scale solutions, from single-platform deployments to large defense programs involving hundreds of units with full lifecycle support.

How we work

We design modular, scalable, and certifiable systems for different mission profiles. Whether it’s an autonomous vehicle, a missile, or a surveillance system, we provide engineering and manufacturing adapted to operational needs. From mechanical actuation to AI-enhanced navigation and secure communications, we deliver mission-critical subsystems fully tested and certified.

Integrated subsystems across COMINT, datalinks, navigation and aircraft modernization

We offer interoperable technologies that combine RF communications, electronic warfare, autonomous mobility, and platform modernization. For example, our NATO CMP POD integrates multiple capabilities — from IMINT and SATCOM to GPS anti-jamming — for current and next-gen RPAS such as MQ-9 and Eurodrone.

Integrated systems for defence

We deliver advanced defence systems including electromechanical actuators, RF communications, data links, AI-based autonomous navigation, aircraft modernisation, and multidomain PODs — all designed to enhance operational capability, mission adaptability, and technological sovereignty across land, air, and naval platforms.
