The Turkish Navy will identify vessels on the sea with the Identification Friend or Foe (IFF) Mod 5 Systems as ASELSAN’s systems pass temporary acceptance tests. Within the scope of the Identification Friend or Foe (IFF) Mod 5 Procurement and Reverse IFF Development Projects, signed between the Secretariat of Defence Industries (SSB) and ASELSAN, temporary acceptance activities have been completed for the integration of IFF Mod 5 Long Range Interrogator (LRI) Systems with the Maritime Surveillance Patrol Command Posts and the İzmir and Karadeniz Ereğli Surveillance Coordination Centres (GKM).
During these temporary acceptance activities, tests were conducted using the C72 maritime multi-purpose aircraft and the KILIÇ-2 Class Fast Attack Craft TCG İMBAT (P-337) as counter-test stations. Query/response and target tracking tests were carried out using NATO cryptography.
The test scenario was repeated via control transfers over the İzmir and Karadeniz Ereğli GKMs. This significant test was performed by adding NATO IFF Mod 5 information to the maritime picture using a system developed by ASELSAN with national resources. This project stands as the most comprehensive modernization project conducted with the Naval Forces Command to date in terms of the number of platforms and variety of design solutions. It includes numerous floating platforms and four Maritime Surveillance Patrol Command Posts.
Temporary acceptance activities have been completed for many naval platforms and several Maritime Surveillance Patrol Command Posts, with integration and temporary acceptance activities ongoing for the remaining elements. Surveillance Coordination Centres create a comprehensive maritime picture covering all Turkish waters by integrating information from shore-based radar stations located at the DGKKs with data from all maritime platforms, maritime patrol aircraft, other commands, and relevant public institutions.
Through integrating IFF Mod 5 LRIs with various DGKKs, advanced target detection/tracking algorithms generate track information from the plots provided by the LRIs via the VATOZ Interrogator Control and Display Unit (ICDU). These generated tracks are then transmitted to all maritime and maritime air elements and relevant public institutions through the GKMs.
