The first new Reis-class Type 214TN submarine for the Turkish Navy will be ready for outfitting by the end of the year.
Steelwork on the boat – named Pirireis – is ongoing and is being completed at Golcuk Naval Shipyard following the delivery of material packages from German company Thyssenkrupp Marine Systems, which designs the selected Type 214TN.
Meanwhile the combat system for the submarines has completed testing by Turkish systems house Havelsan and is ready for installation.
Ahmet Muhtar Erdogan, project manager at Havelsan for the Turkish Navy's NTSP (New Type Submarine Programme), told Shephard that the company has been sub-contracted by Atlas Elektronik to develop the software for the ISUS 90-72 CMS for Turkish use.
He said that the CMS was installed at Havelsan's land-based test site and it is 'waiting for the ship to be built'. Erdogan added that after this first boat is completed, Havelsan will complete the entire integration of the software and hardware of the ISUS system into the remaining five boats in the class. This is an important task because of the high percentage content of Turkish systems on the new boats that needs to work seamlessly with each other.
The infrastructure for the land-based test site was completed in 2016 and it can complete factory acceptance tests, further testing and integration testing before installation in the submarines. Havelsan will also perform maintenance, software development and test new sensors and weapon integration activities on the submarines.
Havelsan is also working on designing and producing the Submarine Data Distribution System (NTSP-DBDS), which collects the navigation and sensor data the boat needs and distributes it to the systems. The company is also under contract to Raytheon IDS to manufacture the Mk48 torpedo for the submarines and do the hardware and software integration. Havelsan is also developing the Torpedo Fire Control System (TORAKS) for the Mk48.
A source at TKMS told Shephard that CMS development and integration is usually the most complex task on a submarine. He said the first boat is due to enter service at the end of 2020 or early 2021 with the rest following on a 12-months drumbeat, although the schedule has to be confirmed by SSM.
TKMS and SSM signed the contract for the NTSP in July 2009 to build the 66.3m-long 1,845t boats at Golcuk and after a two year delay this became effective in June 2011 with production starting in late-2015. Golcuk has previously built the Turkish Navy's Type 209 submarines using work packages from TKMS.
Erdogan added that the other major project he is working on is the mid-life upgrade of the Pakistan Navy's Agosta 90B submarines, where Havelsan is responsible for design, development, manufacturing, test and integration of systems onto the platforms, as well as logistics support and training.
The project started in December 2016 and company is managing the sonar systems – both the 'wet' end arrays and the 'dry' end signal processing; the C2 system's tactical situation presentation and sensor integration and coastal and tactical navigation elements; the weapon control system – both torpedo and missile integration; and the DBDS acoustic and non-acoustic sensor integration.
Erdogan said that the Pakistan Navy also wants the integration of some existing sensors that will not be replaced into the new CMS. He added that Havelsan is a sub-contractor to Turkish shipbuilder STM, which is managing the whole project and is looking after the mechanical upgrades to the class.
He said that the upgrade will take 44-months and the project is due for completion in May 2020 after sea acceptance tests.
