Indigenous systems
Turkish-built systems aboard TCG Giresun include:
- GENESIS Muharebe Yönetim Sistemi (HAVELSAN + Deniz Kuvvetleri)
- ASELSAN elektronik sistemler
SSB’s role
Turkey’s Presidency of Defence Industries (SSB) acts as the procurement authority and coordinator for naval platforms: it sets requirements, manages contracts and oversees integration of domestic subcontractors (ASELSAN, HAVELSAN, ROKETSAN, STM, TÜBİTAK). The physical construction is carried out by the prime contractor shipyard and the systems are developed by the respective defence companies — SSB does not itself build the ship.
