Turkish defence vendor STM showcases MILDEN submarine proposal

Turkish defence firm Savunma Teknolojileri Mühendislik A.Ş. (STM) unveiled its design proposal – i.e. x-TS1700 – for the Turkish Navy’s National Submarine/Milli Denizaltı (MILDEN) program at the International Defence Industry Fair (IDEF), which concluded in Istanbul last week.

STM CEO Davut Yilmaz (via Anadolu Agency) said that the x-TS1700 was the outcome of STM’s submarine design studies, which were commissioned by Turkey’s Undersecretariat for Defence Industries (SSM). For STM, utilizing domestic resources and industry capabilities.

As per Shephard Media, the x-TS1700 has a displacement of 1,740 tons. It has a length of 60.14 m and a diameter of 6.5 metres, and can accommodate a crew of 25 (as well as six special forces operatives). The submarine has eight torpedo tubes for heavyweight torpedoes and anti-ship missiles. STM is aiming for a diving depth of 300+ m, top speed of 20+ kts and endurance of 90 days (with air-independent propulsion).

With the aim of ultimately replacing the Turkish Navy’s Type 209 submarines, the MILDEN will take on a wide range of roles including, among others, anti-submarine warfare (ASW), anti-ship warfare (AShW), land attack, intelligence, surveillance and reconnaissance (ISR) and special operations.

Notes & Comments:

Turkey is aiming to ensure that the six upcoming ThyssenKrupp Marine Systems (TKMS) Type 214TN air-independent propulsion (AIP) submarines are the last of its submarine imports. In fact, the Type 214TN program could be considered a bridge to the MILDEN in that a significant portion of the Type 214TN’s sub-systems, such as the combat management system, are being sourced domestically (via Havelsan and Aselsan). The next phase would be to extend these efforts to a locally designed platform – i.e. the MILDEN.

Besides the x-TS1700, STM is also budding to design and develop a miniature diesel electric submarine (SSK) for replacing the Pakistan Navy’s MG110 Cosmo mini-SSKs (MSI Turkish Defence Review). This is one of four naval development programs on STM’s Pakistan roadmap, the other three being the Fleet Tanker, Agosta 90B submarine upgrade program and sale MILGEM Ada corvettes. If the Pakistan Navy proceeds with the proposal, the mini-SSK program could be an avenue for STM – as well as Pakistan’s Maritime Technologies Complex (MTC) – to gain development experience in submarines ahead of the MILDEN.

    We were discussing on Aselsan radars, but I could not reply you as discussion was closed. You said all Aselsan radars are renamed products of original US made radars, and claimed that you can show me “the original products” that Aselsan produces under licence with “different name”. When I give the list of Aselsan radars in production, you didn’t tell the names but simply told these are pesa radars, not state of art.

    Honestly, I was initially surprised with that claim (licence production with differet names) and I honestly ask myself if true. But I am not convinced with your reply.

    Aselsan has shareholders in an international stock market. It has to share any financial movements with public. As a EU candidate, these companies also have to share their Strategic Plans of next year, have to obey that plan and show each progress in their Performance Program Reports once in every 4 monts. So everything is perfectly transperent. Thanks to these reports, we are well aware of technology transfers and licence productions like that of a-129, kt-1 Woongbi, k2, k9. Besides we are aware of the origin of each sub-systems and components of Turkish solutions like the MTU engine on Altay. However, your claim is whole lot of different thing and indeed “misleading”.

    Turkey will soon commission a nuclear plant ( a buy now or never with the limited life supplies thing of course). But making miniaturized ones for submarines is quite far from realization. Their attempt however in that direction, will lead to many other endeavors also and will land them in the pit with Iran etc
