More than 100 participants from 21 German and 30 Slovenian companies gathered at the Slovenian-German Defence Industry Day in Ljubljana on February 13, 2024. Both sides expressed significant interest in expanding their already highly fruitful cooperation, which was clearly demonstrated during more than 170 B2B meetings. The Slovenian Defence Industry Cluster GOIS, which co-organised the event, and its 58 members look forward to collaborating with colleagues from the German Security and Defence Industry Association e.V. to identify needs and business opportunities for both parties. We also extend our gratitude to the Ministry of Defence of the Republic of Slovenia for its continuous support, and to SPIRIT Slovenia and the Chamber of Commerce and Industry of Slovenia for the excellent organisation of the event.
