What is the German Type 214 submarine?

The German Type 214 is an advanced diesel-electric attack submarine equipped with hydrogen fuel-cell air-independent propulsion (AIP). Developed by HDW, now part of thyssenkrupp Marine Systems, it is one of the world's most capable non-nuclear submarines.

Which countries operate the Type 214 submarine?

As of 2026, the Type 214 submarine is operated by Greece, Portugal, South Korea, and Turkey. These countries use variants known as the Papanikolis class, Tridente class, Son Won-il class, and Reis class.

What propulsion system does the Type 214 submarine use?

The Type 214 uses a diesel-electric propulsion system combined with Siemens PEM fuel-cell air-independent propulsion technology, allowing it to remain submerged for weeks without snorkeling.

How deep can the Type 214 submarine dive?

The Type 214 submarine has a test depth of approximately 400 meters (1,300 feet), although its maximum operational depth is believed to be greater.

What weapons can the Type 214 submarine carry?

The Type 214 carries eight 533 mm torpedo tubes and can deploy DM2A4 SeaHake torpedoes, Black Shark torpedoes, UGM-84 Sub-Harpoon anti-ship missiles, and naval mines.

How long can the Type 214 submarine remain underwater?

Using its air-independent propulsion system, the Type 214 can remain submerged for up to two to three weeks without snorkeling, significantly improving stealth and endurance.

What is the crew size of the Type 214 submarine?

The Type 214 submarine is operated by a crew of approximately 27 personnel, including five officers and twenty-two enlisted sailors.

How much does a Type 214 submarine cost?

Depending on configuration and local construction requirements, a modern Type 214 submarine typically costs between 500 million and 700 million US dollars.

How does the Type 214 differ from the Type 212A submarine?

The Type 214 is an export-oriented development of the German Type 212A. While both share fuel-cell AIP technology, the Type 214 lacks certain classified features such as the Type 212A's non-magnetic steel hull.

Why is the Type 214 considered one of the best conventional submarines?

The Type 214 combines low acoustic signatures, advanced sensors, fuel-cell air-independent propulsion, long endurance, and versatile weapon systems, making it one of the most advanced conventional submarines in service.

German Type 214 Submarine: Advanced Air-Independent Propulsion Attack Submarine

The German Type 214 submarine is a highly advanced export-oriented diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft (HDW), now part of thyssenkrupp Marine Systems (TKMS). Combining stealthy air-independent propulsion (AIP), long endurance, and powerful weapon systems, the Type 214 has become one of the most capable conventional submarines in service today. It is operated by Greece, Portugal, South Korea, and Turkey, making it one of the most successful export submarine designs of the 21st century.

    Key Innovation: The integration of Siemens PEM Fuel-Cell Air-Independent Propulsion (AIP) allows the Type 214 to operate submerged for weeks without snorkeling, drastically lowering its acoustic and thermal signature.
  

Background & Development

The Type 214 was developed by Germany's HDW as an export-oriented evolution of the Type 212A submarine. While sharing many technologies with the Type 212A, the Type 214 omits certain classified features such as the non-magnetic steel hull to comply with export regulations and reduce procurement costs.
