Robotic Welding of VCS Interim Products

Project Participants: General Dynamics Electric Boat Project Start: July 2012 The U.S. Navy and General Dynamics Electric Boat (GDEB) have a joint initiative to reduce the construction cost of the VIRGINIA class submarine (VCS). The Navy ManTech Program is participating in this initiative with specific focus on improving manufacturing processes for ship construction. Operations personnel […]

Improved Stud Fixturing Processes

Project Participants: Huntington Ingalls Industries, Inc. Project Start: June 2012 During ship construction, the U.S. Navy shipbuilding industry is required to attach tremendous quantities of equipment with a great variety of configurations, sizes, and weights. Traditionally, equipment is attached by drilling and mounting welded structural foundations. Extensive engineering resources are expended to design these foundations. […]

Improved Welder Productivity

Project Participants: General Dynamics Electric Boat Project Start: April 2012 Welding at shipyards remains a large cost-driver in the construction of US Navy ships. This is particularly evident with the VIRGINIA class submarine (VCS), where there are hundreds of thousands of structural weld joints alone. Therefore, it is no surprise that a large focus has […]

Lead Installation Process Improvement

Project Participants: General Dynamics Electric Boat Project Start: April 2012 In support of the increased construction rates of the VIRGINIA-Class Submarine (VCS), the U.S. Navy and General Dynamics Electric Boat (GDEB) have joined forces to address costs for contractor labor, shipbuilder materials, and government furnished equipment. A goal of reducing lead installation labor hours by […]

High Productivity Aluminum Manufacturing

Project Participants: Alcoa Defense, Inc., Marinette Marine & Austal USA Project Start: February 2012 Currently, aluminum butt welding for each Littoral Combat Ship (LCS) is a labor-intensive and costly process. This is due to the number of weld passes required to complete welds in aluminum of varying thicknesses. The numerous welding passes add unnecessary labor […]

Support of Advanced Coatings

Project Participants: General Dynamics Electric Boat Project Start: June 2011 Preservation is a significant cost driver when considering total ownership costs of Navy Ships. There is great potential to reduce additional costs associated with fleet unit repairs. This General Dynamics Electric Boat (EB) project will provide technical expertise to support an Institute for Manufacturing and […]

Measure, Layout, and Install Ship Components Using 3D Laser Scanning Tool

Project Participants: General Dynamics Electric Boat Project Start: May 2011 This General Dynamics Electric Boat (EB) project seeks to significantly reduce the labor intensive installation of ship components by implementing the use of a high speed (phase-based) 3D laser scanning tool. The 3D laser scanner is a non-contact measuring device, which eliminates expensive manual targeting […]

Digital Radiography Transition for Inspection of Welds and Castings

Project Participants: Newport News Shipbuilding Project Start: November 2010 The current film-based radiographic inspection process uses expensive, non-reusable film and chemicals that contain materials (silver) that are potentially hazardous to the environment and wastes thousands of gallons of water every year. This film-based inspection process is also very cycle-time intensive, requiring manual handling of materials […]

VCS Shipyard Material Flow Processes and Technology

Project Participants: General Dynamics Electric Boat Project Start: July 2010 Process Engineers at General Dynamics Electric Boat (GDEB) are currently executing an effort to drive down the costs associated with material flow within the VIRGINIA Class Submarine (VCS) construction facilities at its Groton and Quonset Point facilities. The two phased, 21 month project could save […]

VCS Supply Chain Manufacturing Technology Review

Project Participants: General Dynamics Electric Boat & Newport News Shipbuilding Project Start: January 2010 Contractor furnished components make up nearly 30% of the overall cost for a VIRGINIA-Class Submarine (VCS). Of that nearly $600M, $146M is attributable to the 40 most costly components. The General Dynamics Electric Boat (GDEB) and Northrop Grumman Shipbuilding-Newport News (NGSB-NN) […]
