U.S. Navy Exploring New Concepts, Procurement Priorities for ASWOct 20, 2005 00:08 UTC by Defense Industry Daily staff
Modern diesel submarines have advanced propulsion systems and coatings, and many of them are hard to detect with the current sonar technologies aboard the U.S. Navy’s nuclear-powered submarines and surface ships. As nations in Asia and beyond race to buy these vessels, the US Navy’s Antisubmarine Warfare (ASW) Task Force is preparing for that future with a new “concept of operations” that includes new tactics and new technologies. It’s the first major revision of anti-submarine doctrine since the middle of the Cold War.
Chief of Naval Operations Adm. Vernon Clark approved this new concept of operations in late December 2004, which will serve as a guiding document to develop future ASW tactics and techniques. It’s built on the notion that U.S. commanders will get accurate information about the location of potential enemy submarines, via a network of miniaturized sensors that will be deployed in strategic coastal areas to give commanders an advance view. U.S. ships will also try to beat the enemy by getting to a contested area faster, before they have a chance to deploy their submarines. Other tactics will include decoys and deception, information operations and psychological warfare.
In order to better understand what technologies are available in the private sector, the ASW task force plans to issue “broad area announcements” to industry on a regular basis. Expected procurement and research priorities under the new ASW concept of operations include waterborne and airborne sensors that are cheap enough to deploy in large numbers, but capable of processing most information on their own due to bandwidth restrictions. Another items on the priority list include an overarching command-and-control network for the U.S. Navy and the other services that can tie information together, and a “rapid attack” torpedo that can be guided with pinpoint accuracy.

As a result, submarine defenses for the carrier and its accompanying warships will be reviewed… The submarine was spotted by carrier-based aircraft conducting routine surveillance… “Our China analysts appeared to be stunned that China would shadow a U.S. carrier as far away as Okinawa,” the defense official said.”
- DID (Nov 7/06) – $8.9M for FY 2007 Support of the USN’s S-3B Vikings. Which are scheduled to be phased out in 2009 in favour of slower, shorter-range helicopters. The “carrier based aircraft conducting routine surveillance” that found the Song Class submarine was probably an S-3 Viking.
