General Dynamics Electric Boat Awarded $1.85 billion Contract Modification For Submarine Production
Electric Boat, a business unit of General Dynamics, announced that it was awarded a $1.85 billion contract modification to a previously awarded contract supporting submarine production. This modification is for long lead time material and preliminary construction efforts for submarine production, as detailed in the June 26 U.S. Department of Defense contract award announcement.“This contract modification allows for the acquisition of critical material and components for Virginia-class submarines that require substantial lead time to manufacture and deliver. It sends a continued

General Dynamics Mission Systems to Develop Clandestine Mine Delivery System
General Dynamics Mission Systems has been awarded a $15.9 million contract by the U.S. Navy to develop its Mining Expendable Delivery Unmanned Submarine Asset (MEDUSA) system.MEDUSA is a tactical, clandestine mining system using an expendable Unmanned Underwater Vehicle (UUV) that can be launched from a submarine torpedo tube. The U.S. Navy is developing MEDUSA to address the need for an advanced maritime mining system with long-range offensive mining capabilities.The scope of the newly awarded research and development effort includes the design, fabrication, and testing of the MEDUSA prototypes and
US Navy Launches Attack Submarine USS Idaho
One of the U.S. Navy’s newest attack submarines, the future USS Idaho (SSN 799), launched from General Dynamics Electric Boat’s Groton, Ct. shipyard into the Thames River, August 6.The "float off," or launch, is a milestone in a submarine's construction, marking the moment it leaves the shipbuilder's facilities and enters the water for the first time, signaling the start of final outfitting, testing and crew certification.“Today’s launch is testament to the strong collaboration the Navy has with its shipbuilding partners,” said Capt. Mike Hollenbach
UUV Integration Will Transform Submarine Tactics
, each TTL UUV would displace a weapon, which in peacetime may make little difference, but would be a serious consideration should war break out. One workaround could be a system that leverages the flexibility of Virginia-class payload tubes, such as the Universal Launch and Retrieval Module from General Dynamics, which utilizes a retractable platform to deploy and recover UUVs of varying displacements.Whereas in the past, submarines have relied on passive sonar and stealth when carrying out their missions, continued success – and survivability - will hinge on how artfully new technologies and
