Defense Business Brief: VR welding; News from SMD; L3Harris opens maritime factory

PASCAGOULA, Miss.—Thick puffs of clouds didn’t stop the sun from beating down on the shipyard. And only a strong morning breeze could cut that Gulf Coast heat. But prospective welders for HII’s Ingalls Shipbuilding need not immediately contend with the elements to get a taste of the trade—thanks to the yard’s air-conditioned virtual-reality welding lab. “If you’ve never worked with your hands before, or used a welding torch, it can feel intimidating,” Brian Blanchette, president of Ingalls Shipbuilding, told Defense One. “Starting in a virtual-reality setting provides a controlled, low‑pressure environment. It not only helps reduce that initial fear, but it also gives instructors much better control and feedback.”And while learning in a classroom may seem unrealistically pleasant, the VR lab speeds up training by giving entry-level students about 10 times more hands-on practice at melting metal than if using standard welding booths in the same amount of class time.Ingalls and Mississippi Gulf Coast Community College opened the lab, which has 48 training stations, in January 2025. About 1,000 students, including apprentices and new employees, have completed the VR welding training before advancing to traditional instruction.The workstations are lined neatly against the walls of a long classroom. There are blue plastic panels with lime-green QR codes in neat rows that mimic welding materials plates. The welder’s helmet, equipped with small cameras and screens, virtually transforms that plastic into steel. There were also different contact tips and attachments that could be swapped out for different tasks. Students are gradually introduced to the realities of their tradecraft: virtually welding barehanded and then with gloves, learning angles, precision, and pace—which oddly meant going much slower than you’d think.I wrapped the hose around my arm, steadied my two-handed grip, and virtually welded about four inches. Holding the right angle was the hardest part.Trainees can see visual aids that measure torch position, speed, angle, the tip’s distance from the plate—all adding up on a scorecard to show progress and areas for improvement. The software is really responsive and felt lifelike—even for someone who had never welded anything before. But there’s one thing VR welding can’t teach: That tactile feeling of gas and fire coming from the nozzle pressing against the steel. “I can’t teach ‘feel’ in here,” my instructor said, “all I can teach is ‘place’.”That doesn’t stop students from practicing until they can get the highest score possible: a 99. Students need a 90 or above before they can progress to the next activity. I got a 92 on my first try on a very basic step.
