Turkish President Recep Tayyip Erdogan was the chief guest at the event, which was attended by numerous Turkish officials, including the Defense Minister, and the Command Echelon of the Turkish Armed Forces.
Speaking at the ceremony, President Erdogan said Turkey plans to commission one Reis-class (Type-214 TR) submarine each year so that the Turkish Navy will have six new submarines by 2027.
One of the most important details of the ceremony was the President’s announcement about Turkey’s future national submarine, the MILDEN (Milli Denizalti). This was the first-ever official statement about this project.
After his speech, President Erdoğan conducted the first welding of the Selmanreis submarine. President Erdoğan and his entourage posed for a commemorative photo afterward.

The contract signed in July 2009 between the Presidency of the Turkish Defense Industries (SSB) and Thyssen Krupp Marine Systems is to build 6 submarines with an air-independent propulsion (AIP) system and place them in the service of the Turkish Naval Forces.
As part of the project, the first submarine PIRI REIS, which is being built at the Golcuk Naval Shipyard, was launched in 2019, floated in the water in March 2021, and is scheduled to enter service for the Turkish Navy in 2022. The second submarine HIZIR REİS, which was dry-docked on 24 May, is scheduled to be commissioned in 2023. From this year on, one submarine will be commissioned every year, and 6 Reis-class submarines will be delivered to the Turkish Navy by 2027. The delivery schedule of the submarines is given below;
TCG Piri Reis – 2022
TCG Hizir Reis – 2023
TCG Murat Reis – 2024
TCG Aydin Reis – 2025
TCG Seydi Ali Reis – 2026
TCG Selman Reis – 2027
About 30 local companies are involved in the project, including Aselsan, Havelsan, STM, Milsoft, and so on.
About Reis-class submarines

The Reis-class submarines feature a single-hull, one-compartment design and an air-independent propulsion system on the proven Howaldswerke-Deutsche Werft (HDW) fuel cell. The submarines have a length of 68.35 meters, an outer diameter of 6.3 meters, a displacement of 1,850 tons, and a capacity of 40 personnel.
ThyssenKrupp Marine Systems have been building the Reis-class submarines (known initially as Type 214 TN) in Turkey’s Golcuk Shipyard. The AIP system uses fuel cell technology, PEM Fuel Cell (2x120kw), and high-capacity batteries (2×324 units). This provides the submarine with the ability to conduct long-endurance deployments without snorkeling.
The boats will deploy heavyweight torpedoes (MK48 Mod 6AT and DM2A4), anti-ship missiles (Sub-Harpoon), and mines. Indigenous heavyweight torpedo Akya and anti-ship missile Atmaca are expected to be fitted to the next submarines of the project. The Reis-class submarine will be able to undertake missions such as littoral water operations to ocean-going patrols, including anti-surface and anti-submarine operations, ISR tasks, and special forces operations. This is mainly thanks to their increased diving depths and their modular ωєαρσи and sensor mix.
