   Ordered by Greece and South Korea, the U-214 class submarine is basically a development of the U-209 class design with a hull further optimized for hydrodynamic efficiency and therefore stealthiness, but with the U-212A class's AIPS (Air-Independent Propulsion System) based on the Siemens PEM (Polymer Electrolyte Membrane) fuel cell technology rather than the Stirling system used in Swedish submarines. Each of the boats has two PEM cells, producing 120 kW (161 hp) per module, and this translates into a submerged endurance of 14 days.

   In October 1998 the Greek government announced that the Greek navy was to procure four U-214 class submarines with the local designation Katsonis class. The first boat is being built by Howaldtswerke of Kiel for planned launch in December 2003 and commissioning in 2005, and the other three are to be completed by the Skaramanga yard of Hellenic Shipyards. The four Greek boats are the Katsonis, Papanilolis, Pipinos and Matrozos. Changes differentiating the U-214 class from the U-212A class include the location of the diving planes on the forward part of the hull rather than the conning tower, more conventional control surfaces (horizontal and vertical elements rather than an X-configuration) at the stern, eight rather than six swim-out rather than water ram discharge bow tubes (including four fitted for Harpoon anti-ship missiles), a hull made of different materials for a greater diving depth, and slightly different electronics event though a similar Zeiss optronic periscope is used.

   It was in December 2000 that the South Korean defense ministry selected the U-214 in preference to the French Scorpene design (and the Russian offer of three Kilo class boats) to meet its KS-II requirement for three submarines. The contract to built the new boats was awarded to Hyundai Heavy Industries rather than Daewoo Shipbuilding and Marine Engineering, which built South Korea's nine Chang Bogo (Type 1200 subclass of the U-209 class) boats. In 2009 South Korea ordered a second batch of another six U-214 class submarines with an air independent propulsion system.
