Defence Tech Companies in Spain

Spain hit NATO's 2 per cent GDP defence spending threshold in 2025, committing roughly €33 billion annually through a national industrial plan that channels 83 per cent of contracts to Indra, Airbus and Navantia. Indra holds 45 per cent of that share with contracts running to 2037 and is the national industrial lead for the Future Combat Air System. Navantia anchors the naval side, covering frigate modernisation and new vessel construction out of its shipyards in Ferrol and Cadiz.
