The Barbel class of submarines, the last diesel-electric propelled submarines built by the United States Navy, incorporated numerous, radical engineering improvements over previous classes. They were the first production warships built with the teardrop-shape hull first tested on Albacore (SS-569), and the first to use an "attack center" within the hull rather than a conning tower in the sail.

In mid-2004, the government of the Republic of China (Taiwan) allocated NT$412.1 billion to buy eight diesel-electric submarines for the Republic of China Navy. Most countries that build submarines for export, such as Germany, cannot deal with Taiwan without harming their relations with the People's Republic of China, so many analysts expect the United States to either sell the plans for the Barbel class or to actually build the submarines.
