National Production Integrated Underwater Combat Management System – Preveze (MÜREN-PREVEZE)


The National Production Integrated Underwater Combat Management System (MÜREN-PREVEZE) Project aims to develop a unique underwater warfare management system for Preveze class submarines. This system has the ability to work integrated with acoustic sensors, as well as the ability to be adapted to non-acoustic sensors. It also offers important capabilities such as TMA-based track/target management and weapon engagement management. National integrated underwater systems, precision positioning module and weapon control unit for DM2A4/AKYA torpedoes included in the project are among the remarkable features. This innovative project will strengthen our national defense capacity by increasing the effectiveness of our Preveza class submarines in underwater operations. The technical features of the system can be listed as follows:

• National Integrated Underwater SYS,
• Sensor integration and trace/target management,
• Integrated Sonar dry side signal processing,
• Target Movement Analysis (TMA) and tactical planning,
• Precise Positioning Module,
• Weapon control unit for DM2A4/AKYA torpedoes,
• National Acoustic Warfare Support Center.

MILSEC 4 - Secure IP Terminal


While the MİLSEC-4 terminal offers an up-to-date solution for next-generation secure communication (voice, data and video) in IP networks, it provides an uninterrupted communication service by maintaining the compatibility of secure voice communication in PSTN networks with PSTN secure phones in use.

Configuration, surveillance and software update processes of MILSEC-4 terminals are carried out securely remotely using the Security Management Center (GYM). MİLSEC-4 terminal is capable of IP Network Key Loading (IPAAY) through secure communication with GYM without the need for an additional device.

MİLSEC-4 terminals are interoperable with MİLSEC-1A and MİLSEC-2 phones and offer the opportunity to replace MİLSEC-1A and MİLSEC-2 phones without interruption in the gradual transformation of PSTN networks to next generation IP networks.


  • End-to-end secure voice communication in PSTN networks
