During IDEF 2017, the international defense exhibition held in Istanbul, Turkish company STM signed a LOI (letter of intent) with German Shipbuilding group ThyssenKrupp Marine Systems (TKMS).
Talking to Navy Recognition, an STM representative explained that the LOI calls for cooperation between the two companies on a potential contract to built three submarines for the Indonesia Navy (TNI AL). The first submarine would be built in Turkey and two more in Indonesia.
The design being offered is based on the future Turkish-configuration Type 214 diesel-electric submarine (SSK) currently being built by Gölcük Naval Shipyard in Kocaeli for the Turkish Navy (six Type 214TN submarines have been ordered).
As part of the agreement, STM would act as prime contractor if Indonesia was to select the Type 214 design. Other companies such as DSME from South Korea and DCNS from France are also proposing their design to Indonesia.
The Type 214 SSK is developed by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The Type 214 submarine is derived from the Type 212.
Type 214 submarines have a length of 65 m., a beam of 6.3 m, a draught of 6 m. and are capable of diving to a depth of 400 m. Their crew is comprised of 40 sailors. Their weapons include mines, torpedoes and anti-ship missiles which are launched from eight 533 mm. tubes.
