Indra Group of Spain has signed a collaboration agreement with engineering consultancy Tresca to support the development of a new drone manufacturing facility in León as demand for unmanned systems continues to rise across Europe.
The memorandum of understanding integrates Tresca into Indra’s global supply chain and assigns the León-based firm responsibility for providing specialized engineering support for the new industrial site. The facility will be located in the Villadangos del Páramo industrial estate and forms part of Indra’s broader strategy to expand domestic production of defense technologies, including drones, air defense systems, and land vehicles.
According to the company, the plant will focus on manufacturing uncrewed aerial systems (UAS) and loitering munitions, capabilities that have become increasingly important in modern warfare. Once operational, the facility is expected to generate around 200 jobs and strengthen Spain’s defense industrial base.
With more than 25 years of engineering experience, Tresca will assist in designing and implementing the infrastructure required for the site. Indra noted that the partnership will help establish a distributed defense manufacturing ecosystem across Spain, enabling faster delivery of military technologies.
Drone Manufacturing Expands Across Europe
Indra’s project follows a wave of drone manufacturing investments across Europe. In November 2025, STARK opened a production facility in Swindon, United Kingdom, its first factory outside Germany, to produce the Virtus loitering munition and other autonomous systems, with plans to manufacture thousands of drones annually.
In February 2026, Ukrainian drone manufacturer Ukrspecsystems launched a production complex in eastern England, including a factory in Mildenhall and a testing facility in Elmsett, aimed at securing long-term supplies of surveillance drones for Ukraine and strengthening defense cooperation with United Kingdom.
Meanwhile, Meridein Group from Estonia announced plans in 2025 to build a high-capacity UAS plant capable of producing up to 2,000 drones per day to support the Baltic region’s defense needs, with initial production expected this year.
Another initiative emerged in 2024, when Summa Defence revealed plans to establish a drone production facility in Finland in cooperation with Ukrainian companies, aimed at expanding large-scale drone manufacturing for both Ukrainian and European defense customers.
