Such a publication would have to provide verified and unclassified information on the capabilities of our industry in a user-friendly format, thus facilitating its dissemination as widely as possible. Another essential requisite was its impartiality and openness to the entire industry of the sector. In line with these parameters, which are still valid, we present today what is already the fourth edition of the ?Catalogue of the Spanish Defence Industry 2023-2024? (former editions are from 2016, 2017-2018, 2019-2020 and 2021-2022). It is therefore a fully consolidated publication in its specific field. The catalogue has been very well received in all forums in which it was presented, both through our Defence attachés and counsellors, who carry out their work in our embassies and in international organisations, and also through the activities developed by the OFICAEX in its various international undertakings. It has thus proved to be a very useful tool in the institutional support to the internationalisation of our defence industry, for which the OFICAEX is responsible.
