Comments: A really nice little class of SSK, the Walrus-class boats have a good balance of weapons, sensors, and endurance. The lead boat of the class suffered a fire during building and was delayed in delivery.
Germany
Of all the nations on earth, none has a stronger submarine combat tradition than Germany. Twice in this century the German U-boat fleets have driven England to the brink of starvation and defeat. Today, though, the U-boats of the modern German Navy are a much more modest force, though they probably reflect the missions they would be required to execute better than their counterparts from the two world wars. The new generation of U-boats are tailored to the coastal waters of the Baltic, with endurance and weapons loads to match. The German boats have proven to be a great success, particularly in export sales. In fact the Type 209 has actually outsold the Russian Kilo class in exports, making it the Volkswagen of conventional submarines. Their newest boats, the Type 212s, are capable of being equipped with a liquid oxygen/hydrogen fuel cell AIP system.

Comments: The newest of the German U-boats. These boats will be equipped with a fuel cell AIP system, though defense cuts could severely affect construction.
Class name: Type 206/206A
Producer (country/manufacturer): Germany/Howaldtswerke-Deutsche Werft, Rheinstahl Nordsee-werke
Displacement (surfaced/submerged): 450/520

Speed (knots): 17 (submerged)
Number in class: 5
Users: Germany, Denmark
Comments: An earlier version of the Type 206, these units will probably be sold or retired in the current round of German defense cuts.
Class name: Type 209 (1100, 1200, 1300, 1400 variants)
Producer (country/manufacturer): Germany, Turkey, Brazil, South Korea/various shipyards
Displacement (surfaced/submerged): 1,207-1,586 (submerged)
Dimensions (ft/m): Length: 177.4/54.1-200.7/61.2 Beam: 20.5/6.3 Draft: 18/5.5
Armament: Eight 533mm torpedo tubes with 14 weapons
Machinery: Diesel-electric drive with one 7-bladed screw; 5,000 SHP
Speed (knots): 22 (submerged)
Number in class: 34 + 15
Users: Argentina, Brazil, Chile, Colombia, Ecuador, Greece, Indonesia, South Korea, Peru, Turkey, Venezuela
Comments: The Type 209 variants differ predominantly in length and displacement, although the sensor, combat, and other electronics fits will also vary depending on when the particular unit was built. Even though the design is over twenty years old, the Type 209 is still being built for customers today, and is the most successful submarine design outside of Russia and the United States.
Class name: IKL Type 1500
Producer (country/manufacturer): Germany; India/Howaldtswerke-Deutsche Werft; Mazagon
Displacement (surfaced/submerged): 1,655/1,810
Dimensions (ft/m): Length: 211.2/64.4 Beam: 21.3/6.5 Draft: 20.3/6.2
Armament: Eight 533mm torpedo tubes with 14 weapons
Machinery: Diesel-electric drive with one 7-bladed screw; 6,100 SHP
Speed (knots): 23 (submerged)
Number in class: 3 + 1
Users: India
Comments: The Type 1500 is normally listed as a Type 209 variant; however, the 1500 has a larger pressure hull and internal compartmentation, which makes it a different design. The internal arrangement of equipment is for all intents and purposes the same as on a Type 209. The Type 1500 is the only Western-designed submarine with an emergency escape sphere in case the boat sinks.
Japan
Japan started building its submarine force early; its navy was the first to use subs in combat, during the Russo-Japanese war in the early 1900s. Though Japan produced some of the most advanced boats of World War II, they never really used them to best advantage. Today they operate a large force of SSKs based on the American Barbel class of diesel submarine.
