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.

Speed (knots): 20 (submerged)

Number in class: 10

Users: Japan

Comments: Very quiet boats armed with both torpedoes and American UGM-84 sub-Harpoon antiship missiles. Capable of very deep operations, the Yushios are updates of the earlier Uzushio class.

Italy

While the uninformed might not think of Italy as a power in the submarine world, this would be a severe underestimation. Italy has a long and proud history of submarine design, construction, and operations. In World War II, Italian subs did a lot of damage to Allied shipping, particularly in the tight waters of the Mediterranean. Following the war, Italy began to build up a substantial force of diesel-electric boats with units constructed in their own yards. Today it is an extremely capable force, which continues to be upgraded with the finest weapons and sensors produced in Italy.
