STM, recognized for its contributions to naval engineering within Turkey, has been selected to manage system procurement and integration for the mid-life update of the Type-209/1400 Gür-class Submarines. This project is aimed at modernizing vital navigation, mechanical, and communication systems to prolong the submarines' operational lifespan.

This initiative is conducted under the guidance of the Presidency of the Republic of Turkey’s Defence Industry Agency (SSB), involving STM alongside other Turkish defense entities such as Aselsan, ASFAT, and HAVELSAN.

This collaborative effort is part of a strategic push towards enhancing the self-reliance of Turkey's defense technology capabilities, specifically targeting the modernization of the Turkish Navy's submarine fleet to bolster its presence in the strategic maritime domain known as the Blue Homeland.

 An extension to the scope of the Preveze-Class Submarine Modernization Program to include the Gür-Class Submarines was formalized with a contract amendment signed on January 17, 2024. The program's initial phase will concentrate on updating selected navigation, machinery, and communication systems, aiming for completion within six years.

Additionally, STM has been tasked with the integration of the domestically developed Integrated Combat Management System (MÜREN) by TÜBİTAK BİLGEM into both Preveze and Gür-class submarines.

The upgrade of the Gür-Class submarines, which began commissioning in 2004, is part of a wider modernization effort that also includes the Preveze-Class Submarines, started in 2019. This effort has seen the integration and acceptance of several systems on board the TCG Preveze.

Beyond the national scope, STM's expertise extends to international projects, including the modernization of Pakistan's Agosta 90B Khalid-class submarines, and the development of new Reis-class submarines with air-independent propulsion systems for the Turkish Navy.
