Robots and Lasers Are Bringing Shipbuilding into the Digital Age

BY MARCUS WEISGERBER

Even decades-old aircraft carriers are being mapped onto digital models at Newport News Shipbuilding.

NEWPORT NEWS, Va. — When the USS George Washington took shape here in the late 1980s, endless paper blueprints guided the welders and shipfitters of Newport News Shipbuilding. Now, with the aircraft carrier back in a drydock for its midlife overhaul, shipyard workers are laser-scanning its spaces and bulkheads.

They're compiling a digital model of the 104,000-ton carrier, which will allow subsequent Nimitz-class projects to be designed and planned on computers. That will help bring the shipyard's carrier-overhaul work in line with its digital design-and-manufacturing processes that are already speeding up construction and maintenance on newer vessels.

Newport News executives say these digital shipbuilding concepts are revolutionizing the way ships are designed and built.

“We want to leverage technology, learn by doing and really drive it to the deckplates,” Chris Miner, vice president of in-service carriers, said during a tour of the shipyard. This is the future. This isn't about if. This is where we need to go.”

This storied shipyard, now a division of Huntington Ingalls Industries, has been building warships for the U.S. Navy for more than 120 years. Some of its buildings are nearly that old, and some of its employees are fifth-generation shipbuilders. But the technology they use to design, build, and overhaul submarines and mammoth aircraft carriers is rapidly changing. Paper schematics are quickly becoming a thing of the past, being replaced by digital blueprints easily accessible to employees on handheld tablets.

“The new shipbuilders coming in, they're not looking for you to hand them a 30-page or a 200-page drawing,” Miner said. “We're really transitioning how we train folks and how we do things as far as getting them proficient.”

This digital data will “transform the business,” said Miner.

The technology is spreading beyond the shipbuilding sector. Boeing used digital tools to design a new pilot training jet for the Air Force and an aerial refueling drone from the Navy. The Air Force is planning to evaluate new engines for its B-52 bombers, nearly six-decade-old planes, using digital tools. The technology is allowing companies to build weapons faster than traditional manufacturing techniques.

Engineers here at Newport News Shipbuilding are already using digital blueprints to design ships, but they plan to expand the use of the technology into manufacturing in the coming years.

“We want to be able to leverage off all that data and use it,” Miner said. “There's lots of things we can do with that [data].”

The USS Gerald Ford — the Navy's newest aircraft carrier and first in its class — was designed using digital data. The Navy's new Columbia-class nuclear submarines are being digitally designed as well.

Parts for the future USS Enterprise (CVN 80) — the third Ford-class carrier — are being built digitally. Data from the ship's computerized blueprints are being fed into machines that fabricate parts.

“We're seeing over 20 percent improvement in performance,” Miner said.

When the Navy announced it would buy two aircraft carriers at the same time, something not done since the 1980s, James Geurts, the head Navy acquisition, said digital design would contribute to “about an 82 percent learning from CVN79 through to CVN 81” — the second through fourth Ford ships. Geurts called the savings “a pretty remarkable accomplishment for the team.”

In the future, even more of that data will be pumped directly into the manufacturing robots that cut and weld more and more of a ship's steel parts.

“That's the future,” Miner said. “No drawings. They get a tablet. They can visualize it. They can manipulate it, see what it looks like before they even build it.”

As shipyard workers here give the George Washington a thorough working-over, they are using laser scanners to create digital blueprints of the ship. These digital blueprints are creating a more efficient workforce and reducing cutting as many as six months from a three-year overhaul, Miner said.

The top of its massive island — where sailors drive the ship and control aircraft — has been sliced off. It will be rebuilt in the coming months with a new design that will give the crew a better view of the flight deck.

The island already sports a new, sturdier mast that can hold larger antennas and sensors. Shipyard workers lowered it into place in early March.

The yard is also combining its digital ship designs with augmented reality gear to allow its designers and production crews to virtually “walk through” the Ford class's spaces. This helped the yard figure out, for example, whether the ship's sections were designed efficiently for maintenance.

In addition to robots, the additive manufacturing techniques, like 3D printing, could speed shipbuilding even more and reduce the Navy's need for carrying spare parts on ships. The Navy is testing a valve 3D-printed here.

Right now, at a time when the Navy is planning to drastically expand its fleet size, shipyards like Newport News are expanding, but not yet to the levels of the Reagan military buildup of the 1980s. Despite the technology advantages, Miner said people still play essential roles in the manufacturing process.

“It's really not about reducing our workforce as much it is about doing more with the workforce we have,” he said. “We're still going to hire people. We still have to ramp up. There's still hands-on things that are always going to have to be done. But it definitely helps us with cycle time to be able to build things quicker” and “enable our workforce to be more efficient.”

    Space Software Startup To Pursue SDA Contracts

    NewSpace Networks will bid against Lockheed Martin for bankrupt Vector Launch's GalacticSky software-defined satellite assets, says co-founder Shaun Coleman. By THERESA HITCHENS WASHINGTON: Three of the founders of bankrupt Vector Launch have created a new startup, NewSpace Networks, to develop space software products for applications such as data analysis, cybersecurity, and the Internet of Things (IoT). As one of their first forays into the market, the company intends to respond to the Space Development Agency's January call for “leap-ahead technologies” for its evolving DoD space architecture. The new San Jose-based company is eyeing SDA's top two priorities: the so-called ‘transport layer' for Internet and communications connectivity and the ‘tracking layer' that will also cover hypersonic missiles. NewSpace Networks leadership believe they could provide capabilities to the ‘battle management layer,' and the ‘support layer' to enable ground and launch segments to support a responsive space architecture. “We could occupy several of those layers,” Robert Cleave, formerly Vector's chief revenue office, told me in a phone conversation today, which included NewSpace Network co-founders Shaun Coleman and John Metzger. Coleman was the first investor in Vector Launch; Metzger was vice president of software engineering. As we reported, the SDA's Jan. 21 Broad Area Announcement gives interested vendors one year to pitch their ideas. Coleman said that NewSpace Networks is the only company focused on creating a software-based infrastructure in space. Rather than building satellites, Cleave explained, “we see ourselves as a provider of software that makes the satellite smarter.” The idea is to move the aerospace industry from its current hardware focus to a focus on software, as has happened at big tech firms across Silicon Valley and is recognized by many of the Air Force's leadership. NewSpace Networks intends to target military and defense-related customers, along with commercial firms and civilian government agencies. This includes pitching to be a part of DoD's efforts to develop and use 5G high-speed communications capabilities and to provide connectivity to Army vehicles. But it also is looking at potential sales outside of the traditional aerospace community, such as vendors of autonomous vehicles, city governments interested in infrastructure monitoring, and even direct consumer sales of healthcare devices and entertainment services. The wide variety of potential customers is based on the fact that NewSpace Networks' planned products are focused on computing, data storage and processing capabilities at the edge, ones that have a wide variety of potential uses. According to today's announcement, NewSpace Networks's initial products will focus on “the unique challenges of edge computing via space connectivity.” But the company's tech also could be used with aircraft, drones or aerostats serving as the connectivity node, the co-founders explained. The company also intends to work on: Data analytics and analysis; Cloud integration; Network optimization; Virtualization & Hyperconvergence (the latter is industry jargon for combining computing, storage and networking in a single system); Space and air integration; Security and encryption; Application lifecycle management; and IoT enablement. Tuscon-based Vector was one of three commercial space firms chosen in April by the Defense Advanced Research Projects Agency for its DARPA Launch Challenge, a $12 million competition to rapidly launch small satellites to Low Earth Orbit (LEO), until its surprise withdrawal in September due to financial difficulties. The other two companies were Virgin Orbit, which withdrew in October to concentrate on more lucrative customers, and the secretive California-based startup Astra, that first went public in early February via a website. According to a Feb. 3 profile in Bloomberg Businessweek, the firm intends its first launch on Feb. 21. Vector declared Chapter 11 bankruptcy in December, and as colleague Jeff Foust reported on Jan. 24 announced it would auction off its assets. Vector already has a $4.5 million bid from Lockheed Martin for its GalacticSky software-defined satellite technology — essentially a computer on orbit that can be configured for various satellite missions that will be accepted if no other firms issues a bid by Feb. 21. If others throw their hats in the ring, there will be an auction for GalacticSky on Feb. 25. And guess what? NewSpace Networks intends to do just that. “We will be bidding for GalacticSky as well,” Coleman said, noting that I was the first reporter they have told. The founders believe that GalacticSky's technology, that allows a satellite to act more like a cloud node than a mainframe computer, would be complementary to their own developments. Even if they don't win the auction, they hope to work with whoever wins. https://breakingdefense.com/2020/02/space-software-startup-to-pursue-sda-contracts
