The Type 214 is a class of diesel–electric submarines developed exclusively for export by Howaldtswerke-Deutsche Werft GmbH (HDW).^[2] It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class combines the design principles of the Type 209 submarine family and the features of the Type 212A submarine.^[2] However, as an export design, it lacks some of the classified technologies of the Type 212 such as the non-magnetic steel hull that makes it difficult to detect using a magnetic anomaly detector.^[3]

Due to improvements in the pressure hull materials, the Type 214 can dive nearly 400 metres (1,300 ft).^[4] It can also carry food, fresh water and fuel for 84 days of operation.

A contract to build four submarines for the Hellenic Navy was signed 15 February 2000 and a fourth unit was ordered in June 2002. The first submarine was built at HDW in Kiel, Germany and the rest at the Hellenic Shipyards Co. in Skaramangas, Greece. The Hellenic Navy named them the Papanikolis class.

The Republic of Korea Navy has ordered nine Type 214 submarines, designated as Son Won-Il class, to be built in Korea by Hyundai Heavy Industries and Daewoo Shipbuilding & Marine Engineering; three first batch models entered service since 2007, and six second batch models entered service from 2012.
