  Statement of Electric Boat President Kevin Graney on US Navy Award of Columbia-class Ballistic Missile Submarine Contract

  Groton, Conn. June 22, 2020 - General Dynamics Electric Boat president Kevin Graney issued the following statement about a US Navy contract award announced today. "The shipbuilders of Electric Boat recognize the responsibility and welcome the opportunity to deliver the Columbia class. Columbia is our nation's top strategic defense priority and, as the prime contractor, we will provide the safest and most capable class of submarines in the defense of our nation. As we move toward full scale construction later this year, Columbia's design is more advanced than that of any previous submarine program. We stand ready to execute on this critical program and have made extensive preparations by hiring and training the next generation of skilled shipbuilders, expanding and modernizing our facilities and strengthening our supply base." Background information The Navy announced today that General Dynamics Electric Boat has been awarded a contract modification for the design completion, engineering work and design support efforts for the Columbia Class of Ballistic Missile Submarines. An option valued at $9.47 billion supporting the construction of the first two ships of the Columbia class is established as part of this modification. Electric Boat is a wholly owned subsidiary of General Dynamics (NYSE: GD). Electric Boat is the prime contractor on the design and construction of 12-ship Columbia class, which will replace the aging Ohio class of ballistic missile submarines. Electric Boat will manage numerous vendors and suppliers to do this work. Advanced construction began in 2017 at the company's facility in Quonset Point, Rhode Island. Final assembly and test of the Columbia class will take place starting in 2024 at Electric Boat's shipyard in Groton. General Dynamics is investing $1.8 billion in capital expenditures to construct and expand its facilities to support the construction of the Columbia class, the world's most advanced strategic missile submarine. The company's three primary locations are in Groton and New London, Conn.; and Quonset Point, R.I. Its current workforce is more than 16,000 employees.

  LOCKHEED MARTIN CONTRACT TO MARRY MACHINE LEARNING WITH 3-D PRINTING FOR MORE RELIABLE PARTS

  U.S. Navy research contract could make complex metal additive manufacturing a reality both in production centers and deep in the field DENVER, Oct. 1, 2018 /PRNewswire/ -- Today, 3-D printing generates parts used in ships, planes, vehicles and spacecraft, but it also requires a lot of babysitting. High-value and intricate parts sometimes require constant monitoring by expert specialists to get them right. Furthermore, if any one section of a part is below par, it can render the whole part unusable. That's why Lockheed Martin (NYSE: LMT) and the Office of Naval Research are exploring how to apply artificial intelligence to train robots to independently oversee—and optimize—3-D printing of complex parts. The two-year, $5.8 million contract specifically studies and will customize multi-axis robots that use laser beams to deposit material. The team will develop software models and sensor modifications for the robots to build better components. Lockheed Martin Metal 3D printer "We will research ways machines can observe, learn and make decisions by themselves to make better parts that are more consistent, which is crucial as 3-D printed parts become more and more common," said Brian Griffith, Lockheed Martin's project manager. "Machines should monitor and make adjustments on their own during printing to ensure that they create the right material properties during production." Researchers will apply machine learning techniques to additive manufacturing so variables can be monitored and controlled by the robot during fabrication. "When you can trust a robotic system to make a quality part, that opens the door to who can build usable parts and where you build them," said Zach Loftus, Lockheed Martin Fellow for additive manufacturing. "Think about sustainment and how a maintainer can print a replacement part at sea, or a mechanic print a replacement part for a truck deep in the desert. This takes 3-D printing to the next, big step of deployment." Currently, technicians spend many hours per build testing quality after fabrication, but that's not the only waste in developing a complex part. It's common practice to build each part compensating for the weakest section for a part and allowing more margin and mass in the rest of the structure. Lockheed Martin's research will help machines make decisions about how to optimize structures based on previously verified analysis. That verified analysis and integration into a 3-D printing robotic system is core to this new contract. Lockheed Martin, along with its strong team, will vet common types of microstructures used in an additive build. Although invisible from the outside, a part could have slightly different microstructures on the inside. The team will measure the performance attributes of the machine parameters, these microstructures and align them to material properties before integrating this knowledge into a working system. With this complete set of information, machines will be able to make decisions about how to print a part that ensures good performance. The team is starting with the most common titanium alloy, Ti-6AI-4V, and integrating the related research with seven industry, national lab and university partners. About Lockheed Martin Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 100,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. This year the company received three Edison Awards for ground-breaking innovations in autonomy, satellite technology and directed energy.
