Partnerships

Four partnerships are on record, tiered core and minor.

• STM (Savunma Teknolojileri Mühendislik ve Ticaret A.Ş.)coreStrategic or Co-development Partner · 23 September 2021STM and Gürdesan partnered to manufacture the torpedo tube section (Section 50) for Reis class submarines — the first domestically produced such component in Turkey. STM served as the main contractor and coordinator, with Gürdesan as the submarine shipyard (alt-yüklenici) manufacturing Section 50 at Gürdesan facilities. The first unit was delivered to Gölcük Naval Shipyard in September 2021. Sections for submarines 3, 4, 5, and 6 were targeted for delivery by March 2022. The project represents a critical technology transfer milestone for Turkey's naval defense industry.
• ThyssenKrupp Marine Systems (TKMS)coreTechnology or IntegrationGerman prime contractor for Reis class submarine project. TKMS originally manufactured Section 50 (torpedo tube section) for the first two submarines in the class. For submarines 3-6, production was transferred to Turkey under STM coordination and Gürdesan manufacturing, representing a technology transfer from TKMS to the Turkish industrial ecosystem.
• İstanbul Technical University (İTÜ)minorStrategic or Co-development PartnerGürdesan fabricated and installed a cavitation tunnel for İstanbul Technical University's hydrodynamics research facility, demonstrating engineering collaboration between industry and academia.
• Gölcük Tersane Komutanlığı (Gölcük Naval Shipyard)coreOthersGölcük Naval Shipyard is the primary Turkish Navy shipyard and recipient of Gürdesan's domestically manufactured submarine components. Gürdesan delivered the first Section 50 torpedo tube section for Reis class submarines to this facility.
