"Designed by STM engineers and having started the production of the resistant hull test in June 2022, Turkey's first national submarine for special operations and attack purposes, the STM500, was successfully completed in 2023, including the production of the resistant hull test and quality test processes. With the successful production of the first test block at TEKFEN Manufacturing and Engineering Inc. facilities under the supervision and control of STM engineers, with completely domestic infrastructure and facilities, the test blocks of a war submarine were produced domestically in the civilian industry for the first time in Turkey."

They've completed the test hull in 2023, and only just shown it off Today. I wonder what state actual production model is in.

While I was on the ferry on the Bosporus, look what I was lucky enough to take some pics

"The Malaman is over 1.8 metres long, has a diameter of 533 mm, compatible with heavy torpedo launching tubes, weighs 600 kg and can operate at temperatures between –2.5°C and +36°C, and at depths over 100 metres. It contains an undisclosed amount of in sensitive plastic-bound explosive. The mine is fitted with acoustic, magnetic and pressure sensors which data, combined together, allow precise identification of naval vessels. The identification friend or foe algorithm avoids the mine to be set off when friendly assets navigate in the area. No details were provided on the level of intelligence contained in the detection system, but it is quite probable that a database allows to precisely identifying the traffic, eventually activating the Malaman on pre-selected targets."
