Delivery schedule for New Type Submarine Project (NTSP) Contract which was signed on July 2nd 2009 has been effective started on June 22nd 2011. In this context, infrastructure activities and preparations related with submarine construction has been completed at Gölcük Naval Shipyard and the construction of the first submarine has been actually begun.

The launch ceremony of the TCG Piri Reis (S-330) Submarine, the first of the Type 214TN REIS Class Submarines being constructed at the Gölcük Naval Shipyard Command under the €2,060 Billion New Type Submarine Project (NTSP), was held on December 22, 2019, with the participation of President Recep Tayyip ERDOĞAN, Minister of National Defence Hulusi AKAR, Force Commanders and President of Defence Industries İsmail DEMİR. The keel of the TCG Seydi Ali Reis (S-334), the 5th Submarine of the Project, was also laid at the ceremony. In the next phase, the outfitting activities of the TCG Piri Reis Submarine will continue, and the submarine will enter service with the Turkish Navy in 2022 following the Factory Acceptance (FAT), Harbor Acceptance (HAT) and Sea Acceptance (SAT) Tests, respectively.

The Turkish Submarine Fleet has a long history spanning 134 years and has an indispensable place among world navies with its respectable traits and capabilities. With its modern vessels, the Submarine Fleet is one of the most vital combat elements that forges the striking force of the Turkish Navy. The Submarine Fleet Command currently operates a total of 12 submarines, including four AY Classes, four PREVEZE Classes, and four GÜR Classes. The Turkish Navy Submarine Fleet, which is always ready with 12 submarines, is an outstanding deterrent both in our region and worldwide...

To ensure the continued effectiveness of the Submarine Fleet in operational areas in the surrounding seas, the Turkish Naval Force Command (TNFC), seeing the need for modern submarines with quieter hull forms for reduced flow noise, the New Type Submarine Project was launched to acquire a variety of capabilities; an Air Independent Propulsion (AIP) System for long endurance underwater tasks, low acoustic, thermal and magnetic signatures, high capacity batteries, hybrid propulsion, and modern countermeasure systems. The administrative responsibility for this project was given to the Presidency of Defence Industries with the decision of the Defence Industry Executive Committee (DIEC/SSIK) dated June 22, 2005.

The €2,060 Billion New Type Submarine Project (NTSP) contract was signed between the SSB and German TKMS Joint Venture (formerly the HDW-MFI Joint Venture) on July 2, 2009 and entered into force on June 22, 2011. The project covers the construction of six Type 214TN Air Independent Propulsion (AIP) Submarines with the technical support and technology transfer to be provided by TKMS Joint Venture at the Gölcük Naval Shipyard Command, which has previously constructed 11 submarines (three AY, four PREVEZE, and four GÜR-Classes).

The construction of five submarines (the first steel plate of the 5th submarine was cut on December 22, 2019) is underway and the first submarine, TCG Piri Reis (S-330), was launched in December 2019 and will be commissioned with full operational capability in 2022. It will be followed by TCG Hızır Reis (S-331), TCG Murat Reis (S-332), TCG Aydın Reis (S-333), TGC Seydi Ali Reis (S-334) and TCG Selman Reis (S-335). The last submarine in the project will be delivered to the Turkish Naval Forces Command (TNFC) in 2027.

Initially, the class was to be called CERBE and was planned to be 66.3m long with a surface displacement of 1,845 tons. However, significant design modifications were made to meet Turkish Naval Forces Command (TNFC) requirements because of some technical problems with the HDW design, and Turkish engineers found five major design flaws and developed solutions for them. The resulting submarine, which is longer and heavier than CERBE, was renamed as REIS Class in 2014. However, the technical specifications of the REIS Class Submarines were revised, and the total length was increased again following the modifications. Additionally, the number of Cylindrical Metal Hydride Tanks (MHT) that are used to store Liquid Hydrogen, an essential element of the Air Independent Propulsion (AIP) System, has also been increased. The PEM (Polymer Electrolyte Membrane) Fuel Cells of the AIP System use pure hydrogen (H2) to generate power; however, pure hydrogen has toxic properties and is carried in cylindrical double-walled metal hydride tanks. Using seven rows of Cylindrical Metal Hydride Tanks instead of six rows in a CERBE Class design (Each carries a horizontally placed 15.3-ton capacity Liquid Oxygen [LOX] tank in its pressure hull) will considerably increase the amount of hydrogen carried in the Metal Hydride Tanks, which provide the necessary energy for the fuel cells used in the AIP System and will also increase the maximum amount of time that a submarine can stay underwater (Submerged Endurance). The Type 209PN and Type 214 Class submarines have six rows of metal hydride tanks (each row includes six cylinders, three on the right and three on the left) located outside the pressure hull in the bottom of the submarine hull while the Type 209 AIP submarines have five rows. However, the scale model of the Type 214TN New Type Submarine Project, which was revealed by TKMS for the first time at the 8th Naval Systems Seminar held in October 2017, has seven rows of metal hydride tanks outside the pressure hull. This means that REIS Class Submarines will have 6x7 = 42 metal hydride tanks. Before the second revision, the delivery schedule of the REIS Class Submarines was planned as 2021-2026 with a 12-month phase difference, while the new calendar was updated as 2022-2027.

While the height (13.1m/16.5m with the periscopes), width (6.3m), draught (6.8m) and the surface displacement (about 1,855 tons) of this new version, which we call REIS-II, didn’t change; the total length of the submarine was increased to 68.35m (0.75m longer than the first version of the REIS-Class and 2.05m longer than the CERBE Class). The submerged displacement of the submarine is around 2.050 tons. According to the TKMS product brochure, the total length of the new Type 214 Class submarines is 72m, and the surface displacement is about 2,000 tons.

On the other hand, the National Submarine (MILDEN), which will open a new page in the history of Turkish Submarines, is expected to enter service by the second half of the 2030s. Currently, the studies on the feasibility of MILDEN and the technical and operational characteristics of the submarine are continuing while the TNFC carries out manufacturability analysis for the MILDEN vessel. MILDEN will be built at the Gölcük Naval Shipyard Command, which has been doing overhauls of submarines in the TNFC service for 55 years and built submarines for 37 years. Gölcük Naval Shipyard Command is one of the 16 shipyards in the world that can build submarines.

Two BZM120 Proton-Exchange Membrane (PEM, also called Polymer Electrolyte Membrane) Fuel Cell modules (each generates 120kW power) lie at the heart of the Air Independent Propulsion (AIP) System of the Type 214 Class Submarines (the first batch of the U212A submarines and the first batch of the Type 214 boats ordered by the Republic of Korea Navy have 9 (one backup, eight active) BZM34 PEM modules that generate a total of 306kW (400hp) power). The service life of the BZ120 PEM Fuel Cell modules (each weighs 900kg, has a capacity of 500 liters and constitutes of 320 cells), is estimated between 2,000-4,000 hours. This means that after running 2,000-4,000 hours, the BZM120 PEM Fuel Cell modules will need to be replaced. The BZM120 PEM module enables the submarine to navigate at a cruising speed of 2 to 6kt (3.7 to 11.1km) and stay underwater without surfacing for about three weeks, depending on the speed. The Type 214 submarines can reach 12 knots on the surface and 22 knots while submerged. Thanks to its AIP System the submarines can stay underwater for 18 days (approximately 1,248nm/2,311km at 4 knots) without snorkeling to charge its batteries or can travel 12,000nm (2,311km) at 4 knots with maximum fuel and snorkeling.

The Type 214 submarine uses its diesel engines while cruising at high speeds and AIP System for low-speed silent cruising. The main components of the AIP System consist of the PEM Fuel Cell module, cylindrical metal hydride tubes, liquid oxygen tank, and control unit. The submarine can operate for an extended time without surfacing by using the electrical energy generated in the fuel cell module as a result of the chemical reaction between the liquid oxygen and the hydrogen stored in metal hydride tanks. Since the fuel cells use pure hydrogen to generate power, the module can continuously produce electricity as long as there is hydrogen feeding the system.

Construction Process of REIS Class Submarines

While the AY, PREVEZE, and GÜR Class submarines were built with the horizontal construction method using HY-80 high yield steel plates at the Gölcük Naval Shipyard Command, the REIS Class Type 214TN Submarines are being constructed with the vertical construction method, which has been newly introduced to the Shipyard. Vertical construction allows faster production by using more automation and automated welding technologies, including more advanced welding machines and systems which has increased the welding quality. Since Erdemir could not produce ferromagnetic HY-100 and HY-80 high yield steel alloys, the REIS Class Type 214TN Submarines are being constructed with steel plates supplied from Austria.

In the vertical construction method, the steel plates of the pressure hull and the keels supporting them from the inside are built vertically as ring-shaped sections with a length of about 3m, and later the steel hull of the submarine is assembled by rotating the rings and combining them end to end with automatic welding machines. Both ends of this long cylindrical steel hull are sealed with the addition of the forward elliptical bulkhead (dome) and the aft conical bulkhead and the construction of the waterproof and pressure-resistant submarine hull is completed. Apart from the pressure hull, the boat's construction is finalized by adding the upper deck, sail, ballast tanks (aft ballast tank is not pressurized), and the inner compartments. Because of the way the pressure hull is constructed, all the devices, systems, and equipment to be used in the submarine must be outfitted before the pressure hull blocks are combined.

To prevent corrosion and provide durability, the upper deck and the sail sections of the submarines are constructed from Fiber-Reinforced Plastic (FRP), while the hull is built from high-yield stainless steel alloys (HY-80/100) with high corrosion resistance. The bow of the submarine, which is the most critical part of the vessel, will be built domestically at the Gölcük Naval Shipyard Command. Thus, the entire submarine hull will be built for the first time in Turkey. The bow of the TCG I. İnönü (S-360), last Gür-Class (Type 209/1400 Mod) submarines, was also built by Turkish engineers and workers at the Gölcük Naval Shipyard Command. Another critical section to be constructed under the project for the first time at the Gölcük Naval Shipyard Command is the aft conical bulkhead that forms the stern (dome) of the submarine.

REIS Class Submarines consist of 22 sub-blocks, each approximately 3m long, and five main blocks. There are also three internal reinforcements (six in AY, PREVEZE and GÜR Classes) built from the HY-80 steel in different parts of the hull to increase the strength of the submarine further. A single main section of the pressure hull is formed by combining 6-7 sub-sections. The hull of the submarine, on the other hand, is constituted by combining five different main sections, each weighing 840 tons. The internal support elements/parts that provide the main strength of the hull are called ‘keels.’ The keels consists of two parts: WEB and FLENC. WEBs are made of HY-100 steel plates.

Each REIS Class submarine will have around 100 keels (reinforcement element). According to the information we received, during the construction process, first, the non-pressurized aft ballast tanks will be built, and then the keels that form the basis of the pressure hull will be manufactured. Subsequently, the main sections called Section 10, Section 20, Section 30, Section 40, and Section 50, will be constructed.

A special hull constructed from fiberglass is placed on the outside of the pressure hull to reduce the acoustic signature and improve hydrodynamics. Carbon fiber materials are also partially used in the construction of the outer hull, which uses special Radar Absorber Materials (RAM) and paints. Under the leadership of STM, studies were carried out to produce RAM materials and paints to be used in REIS Class Submarines with domestic capabilities.

Incorporating around 100 keels, the construction of each single-hull REIS Class Submarine is estimated to cost 180,000 Man-Days (160,000 for TCG Heybeliada and 140,000 for TCG Büyükada Ada Class Corvettes) and 1.5 Million Man-Hours in total

Timeline:
Design has been evolving since it has initiated, while first profiles were hinted as 80 meters corvette, regional developments has brought new additions and replacements of the systems, first batch of the project, which was shaped in 2002-2003 has been named as "Ada-Class corvette"
2005 - Steel cutting of first ship
2008 - 1st ship is launched
2010 - 1st ship is commissioned


Through 1st to 4th ship the ship has evolved, systems were built and integrated with local components, thus all 4 ships may resemble differences in minor configuration but in overall serves the same purpose.

How is that even possible ? Looks like a Ro-Ro ship ? Where is the living quarters and everything ? Is it down below the water line ? There shoudnt be all that open areas because of the exhaust system and ventilations.

Just representing the shell plating, helicopter hangar arrangement and rhibs. They havent published details yet.
The overall 3D model is meant to demonstare basic utilities, not to great extends of deck plans.

Regarding our domestic amphibious attack ship (LHD) the "Advent" integration to TCG ANADOLU is about to be completed.

Ten million lines of code have been written in the development processes of "Advent", one of the best combat management systems in the world.

More than 50 systems and applications will accompany this masterpiece.

I haven’r had a chance to watch the video yer, but I remember @ANMDT was worried about cancellation and postponements.
These guys are not insiders probably reading some forums and making conclusion and guesses, the projects are still ongoing (ISTIF -TF2000 - DIMDEG - REIS Class -FAC)

Edit: told it without watching the video completely and reading their biography, my bad :)

The host is a former officer, but they give their qualified guesses. I would expect that TSK has their own budget that doesn’t get cut regardless of national economy. National security is priceless.

Majority of projects are on naval shipyards and subcontractors are companies affiliated with state. Only issue could be payment of material and subsystems which i believe is already included in budget for ongoing projects.

As far as I know, a fixed budget for armaments expenditure is set at the beginning of each year, this is then separated from the federal budget and is not available for other things. Unless there are unexpectedly additional costs, the current economic situation should not have any effects on armaments and the military - at least that is how it is handled in most countries....

Yesterday I saw a documentary about Vladivostok and a Russian frigate that was put into service relatively recently and it is said to have the fastest onboard cannon in the world - I forgot the exact date, but I'd be interested in how fast the mentioned one is in an international comparison? Any data about it?
Due to the high frequency of the Russian canon, it should achieve the same performance as 2 onboard cannons -

______________

Edit:

I just did some research - it was probably Russian propaganda, the mentioned vessel is a stealth, multi-purpose corvette - the F532 Bojki -
Features:

The A-190 100mm Canon with a rate of 80 rounds per minute and a range of around 20,000 meters
