ALTEN offers its clients flexibility and added value in cutting-edge projects in the aeronautical sector

ALTEN is a preferred supplier of the largest manufacturers in the aeronautical sector. It ensures a local presence close to the Spanish factories and the possibility of giving support at the transnational level. In addition, it has the ability to intervene throughout the life cycle of the product.

It stands out in the creation of design activities and calculation of structures as well as in the setting and integration of systems, testing, hardware and embedded software design and support to the production lines and the supply chain. In addition, it participates in the challenges of improving productive capacity, aircraft safety and sustainability. This takes place within a context of continuous growth in the demand for products and services in the aeronautical sector.

ALTEN is positioned as one of the national leaders in the aeronautical sector

ALTEN participates in the main international space programmes. In them, it provides design and validation solutions for electronic components, software and structures for satellites and shuttles. All this makes ALTEN a reference company in the aeronautical sector.

In the defence area, ALTEN develops military and combat transport aircraft, military multi-role vehicles and submarines. Our teams offer support for the development of specific versions, thus responding to the needs of different military forces.
