IDEF 2021: Meteksan showcases submarine sonar systems

Meteksan Defence showcases a submarine sonar system at the International Defense Exhibition, IDEX 2021. The firm was assigned by the Defence Industries Presidency of the Republic of Turkey with the approach of "Turkey's Underwater Center of Excellence", transfers its sonar capabilities for surface platforms to submarine platforms.

Systems developed by MeteksanDefence for submarine platforms include hydrophones, side-scan sonar arrays, intercept passive sonar, intercept detection and ranging sonar, digital underwater acoustic modem, hardware and software for sonar systems pre-electronics, signal processing and beamforming, sonar operator interface software. While these completely domestically and nationally developed systems are being used for the modernization activities of existing submarines in the Naval Forces Command inventory, they are also of great importance for Turkey’s MİLDEN National Submarine Project, where national design activities are ongoing.

MSH-01 Hydrophone, which is completely developed by MeteksanDefence with its own resources, is being used as sensors of passive sonar cylindrical hydrophone array (CHA), passive ranging sonar hydrophone array groups, wet-end side own noise analyses (ONA) systems, and cavitation indication (CI) systems of AY/PREVEZE class submarine ships. MSH-01 can be used in the said sonar systems of Type 209 Mod 1000 to Type 209 Mod 1400 class submarines, which are in service both in the Turkish Navy and in worldwide Navies.

MeteksanDefence also produces the sensors, which are mounted along starboard and port sides of submarine hull and form the wet-end side of flank array sonar. The MSH-11 sensor is also intended to be used in flank array sonar systems of Type 209 Mod 1400 class submarines, which are in service both in the Turkish Navy and in worldwide Navies.

Being Contractor of the Sonar Sub Systems of TÜBİTAK BİLGEM in the MUREN PREVEZE National Production Integrated Underwater Combat Management System Development Project, MeteksanSavunma is assigned as responsible for the development of pre-electronic equipment that amplifies and converts the analog signals coming from sensors to digital, as well as the signal processing and beamforming hardware and software of these digital signals. In addition, the sonar developed by Meteksan within the scope of the Intercept Detection and Ranging Sonar (IDRS) Project will be integrated into our PREVEZE Class submarines (Type 209) within the scope of the Project.

The Type 209 is a class of diesel-electric attack submarine developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. The original variant (Type 209/1100) was designed in the late 1960s. The class is exclusively designed for export market. Despite not being operated by the German Navy, five variants of the class (209/1100, 209/1200, 209/1300, 209/1400 and 209/1500) have been successfully exported to 13 countries, with 61 submarines being built and commissioned between 1971 and 2008.
