The Type 214-class submarines, also known as U214 or 214 Type 1200, are an advanced and larger derivative of the German Navy U212 class of conventionally powered submarines. The U214 submarines are provided with eight 533mm torpedo tubes capable of firing missiles through them. The new class of submarines will feature improved hydrogen fuel cells and diesel propulsion system. They have been designed to be stealthier and more capable than previous U212-class submarines.

Greece and South Korea have ordered three U214 submarines each respectively with the first one commissioned by the Greek Navy in 2005, delayed to 2010, and the first Korean submarine commissioned in December 2007. Greece was expected to get one additional U214 submarine as option increasing the total number of U214s owned by its Navy to four, but was cancelled due to the economic crisis. These submarines were built by Hellenic Shipyards and Hyundai Heavy Industries for Greece and South Korea respectively. The Republic of Korea ordered six additional boats with deliveries beginning in late 2014. Between 2009 and 2011 the Turkish Navy ordered six Type 214TN to be built locally by Golcuk Shipyard beginning in 2015.
