Reis-Class AIP Attack Submarine

The Reis-class submarine, Turkey’s latest generation air-independent propulsion (AIP) attack submarine, represents a major leap forward for the Turkish Navy’s underwater warfare capabilities. Based on the German Type 214TN design, the class integrates advanced stealth shaping, fuel-cell AIP technology, and modern combat systems tailored for littoral and deep-water operations. Built by Gölcük Naval Shipyard in partnership with thyssenkrupp Marine Systems (TKMS), the program significantly boosts Türkiye’s maritime deterrence in the Mediterranean, Aegean, and Black Sea regions.

Equipped for multi-mission roles, the Reis class excels in anti-surface warfare, anti-submarine warfare, intelligence gathering, and special operations deployment. Its hydrogen fuel-cell AIP system allows the submarine to remain submerged far longer than conventional diesel-electric boats, offering weeks of silent operation with minimal acoustic signature. This makes the platform especially relevant to U.S. and NATO naval watchers monitoring developments in the region.

The submarine carries eight 533 mm torpedo tubes, supporting heavyweight torpedoes, anti-ship missiles such as the Harpoon, and naval mines. Advanced sonar arrays, flank sensors, and integrated combat management systems enable high-fidelity tracking and engagement in cluttered coastal environments.

With a modern hydrodynamic hull, low-magnetic steel structure, and extensive acoustic dampening, the Reis class is optimized for stealth. Crew efficiency is enhanced through high automation levels, reducing workload while improving mission endurance. As Turkey expands its indigenous defense production, the class serves as a stepping-stone toward fully domestic submarine manufacturing.

Overall, the Reis-class submarine provides a capable, modern, and stealth-focused platform that aligns closely with NATO operational standards and reflects the Turkish Navy’s ongoing modernization strategy.

Reis-class Submarine Price

While the Reis-class submarine is not exported to the United States, its estimated unit cost—derived from the Type 214 program—ranges between $550–650 million, depending on configuration, sensors, and weapons packages.
