Jones Henry, You need to research what you post.
The USN is countering the comeback of desiel boats as I write this....
The USN has no diesel subs to practice hunting. So some time ago they contracted out a Swedish Gotland class boat for these duties.The Boat arrived in San Diego in August and is currently helping the USN find ways to detect and destroy desiel boats. For your information diesel boats are used generally for littoral water and are not intended to venture far out to sea.

Navy to hone hunting skills on Swedish sub

NORFOLK — The Navy has formally agreed to lease a Swedish submarine and its crew for a year so U.S. nuclear-powered subs, as well as other ships and planes, can practice hunting it.
Under a memorandum of understanding signed this week in Norfolk with the Fleet Forces Command, the Swedish navy will send a Gotland-class sub to San Diego, where it will help the sea service train to combat the potential threat of diesel-powered submarines in the hands of rogue nations.
The 200-foot submarine, which displaces 1,490 tons and carries a crew of about 30, will become frequent prey of American sub hunters nearly twice its size. Los Angeles-class fast attack submarines, for example, are 360-feet long, carry a crew of 140 and displace 7,147 tons when submerged.
The U.S. is interested in studying the quietness of the diesel-powered boats, since it no longer has any of its own, Jim Brantley, a spokesman for the Fleet Forces Command, said Wednesday.
Under the $17.5 million contract, the Swedish sub will be transported to San Diego by a heavy lift ship and will provide up to 160 days of service during the contract’s term, Brantley said.
An air independent propulsion system allows it to spend up to two weeks at sea, submerged and without snorkeling, while traveling at five knots, he said. Although it will be attached to San Diego-based Submarine Squadron 11, the vessel will be Swedish-flagged, commanded, manned and operated, with U.S. Navy personnel aboard as riders and observers.
The project also will focus on acoustic analysis of fleet operators aboard all anti-submarine platforms, including carriers, surface ships and aircraft, the Navy said.
“This U.S.-Swedish effort will demonstrate the further development of international interoperability between the two nations,†Inspector of the Royal Swedish Navy, Rear Adm. Jorgen Ericsson, said in a Navy statement.
Nations worldwide continue to acquire quiet and lethal submarines designed to operate in shallow ocean depths, the Navy said. With advanced developments in weaponry and propulsion, the nature of anti-submarine warfare has changed, increasing the risks to U.S. ships.
“This will vastly improve our capability to conduct realistic, effective antisubmarine warfare training that is so critical to the Navy’s ability to accomplish our mission,†said Rear Adm. Donald K. Bullard, director of readiness and training for Fleet Forces Command.
