HAVELSAN completed the command control and warfare management systems of six submarines and the submarine information distribution systems as part of the New Type Submarine Project of the Undersecretariat for Defense Industries (SSB).


In the first phase, HAVELSAN completed the DBDSs which are considered the heart of all submarines, and delivered them to the Gölcük Naval Shipyard Command as part of the Submarine Information Distribution System (DBS) Project, which began in 2001. The last DBDS was delivered in 2021 for the TCG Selman Reis Submarine. As part of the command control and warfare systems delivery, HAVELSAN completed the systems of the last submarine, the TCG Selman Reis Submarine last week. Acceptance procedures were successfully completed with the participation of the SSB, the Turkish Naval Forces Command and HAVELSAN personnel. With the last command control and warfare management system handed over to the Gölcük Naval Shipyard Command in the coming days, HAVELSAN will have be handed over to both the DBDS and command control and warfare systems.


As part of a project to meet the needs of Naval Forces Command, the development of the DBDS for the first submarine was initiated in September 2011. A team of technicians and experts worked at HAVELSAN to develop, manufacture and test the DBDS systems. The project, which primarily involved embedded software, electronics, and hardware engineers, benefited from contributions from system, mechanics, configuration, production, quality, test engineers, project monitoring, integrated logistics support, risk experts, project manager, and technical managers. Prior to this project, the distribution of weapons, sensors and information was carried out via foreign systems, one of the most vital functions of the submarines, and there were significant maintenance and modernization challenges.

The DBDS Project for the TCG Piri Reis, TCG Hızır Reis, TCG Murat Reis, TCG Aydın Reis, TCG Seydi Ali Reis and TCG Selman Reis submarines involved all deliveries in a timely and full-performance process. The system was produced with domestic facilities, from design to integration. The share of the domestic contribution, envisioned at 70 percent, was near 75 percent under the DBDS Contract. The DBDS has passed all these procedures successfully after  being subjected to long and extensive testing of endurance, as it will be used in harsh environmental conditions. All DBDS environmental testing was conducted domestically with the use of local facilities. Using embedded software technology that works in real time, DBDS has uninterrupted integration with 105 different units within the submarine. The DBDS Project covers the production of a total of 7 sets of systems, one of which is in a land-based test environment, 6 of which are in submarines.


The command control and warfare management system of class Reis submarines were all carried out under the responsibility of HAVELSAN. The configuration management, system integration and testing of the software source code was also carried out. For this purpose, the Land-Based Testing System (KKTS) was established at HAVELSAN’s Ankara facilities to provide one-to-one conjugation of submarine hardware and software. HAVELSAN contributes locally to the submarine project with nine business packages and a Mk 48 torpedo integration as part of the Warfare Management System. Finally, with seven separate acoustic sensors, the command control system designed for TCG Selman Reis improved the submarine's listening capabilities and target detection range, as well as its listening and adaption skills to underwater environments. The Port Admission Tests, which are expected to be carried out after the Factory Admission Tests, will be carried out at Gölcük Naval Shipyard. After the installation of devices and the activation of radar and acoustic systems, Sea Admission Tests will begin. As part of the project, HAVELSAN delivered the command control systems of the fifth submarine last year.

Furthermore, in 2021, the Submarine Information Distribution System (DBDS) of TCG Selman Reis, the sixth of the 6 Reis class submarines, was delivered and all DBDS deliveries of the project were finalized. The heart and brainchild of all Reis submarines will be completed with the delivery of command control systems. As part of the project, HAVELSAN undertakes all system development and testing activities for the Land-Based Testing System in its facilities. When the submarines are completed, HAVELSAN engineers will take their signature on critical components such as warfare management, information distribution and torpedo firing control systems. This immense experience of HAVELSAN is targeted at the National Submarine Project (MILDEN), one of Turkey’s most important projects. "We successfully completed the mission in first-class submarines, and we are ready to begin work on the MILDEN Project," stated HAVELSAN engineers.
