LYNN, Mass.—Rosie the robot and her automated compatriot Thomas are the stars of GE Aerospace’s automated manufacturing line at the company’s factory here. Decked in yellow, the towering machines are reminiscent of the Transformer Bumblebee’s dislocated arms. They move in concert seamlessly to collect tools, machine parts, and assemble components for the T700, which are found in Boeing’s Apache and Sikorsky’s Black Hawks, and, in the future,T408 engines for the Marine Corps’ CH-53-K King Stallion.
It’s part of a multiyear $100 million investment in the plant, which is hyperfocused on upgrades—from machines to workflows—to make more engines and deliver them faster.
“This was historically a bottleneck for our businesses,” Dan Martin, who manages manufacturing engineering and leads a team charged with integrating robotics and automation inLynn plant, said of the piece of the business that makes rotating parts, like cooling plates. “We had quality issues here. We had capacity issues here. The robotics piece now comes online, and these lines are no longer constrained for us.”
That need to go fast will be key once the military starts putting in high-volume orders for collaborative combat aircraft, or robot wingmen for fighter jets.
“We’re designing from the very beginning to meet the right production,” starting with small engines, Amy Gowder, GE Aerospace’s president and CEO for its defense and systems division, told reporters Monday. For example, “we did a seven-way exercise, and we’re like, ‘no, we need a tack time of 100 seconds for each [screw], not an hour and a half,” for 70 screws.
In addition to changing techniques and design practices, Gowder said the company is looking for suppliers that are “used to the high volumes we need.”
For the F404/F414 engine, which is found in the F/A-18, “we’re trying to move to a different supply base that has different commercial off-the-shelf type standards that have operated at this volume,” she said. “And when we tell them we want to go from one engine a month to 20 engines a month in like six months or a year, that doesn’t phase them because they’re used to handling the volumes. Only when you get to like 100 engines a month do they start to say, ‘hey, I might need some some investments or capacity to meet that.’”
GE is also conducting “producibility reviews” as it brings on suppliers, she said.
“So we think we designed it correctly. We think we’ve chosen the right types of suppliers that have the capacity and processes we need, but as they actually get the drawing and figure out how they’re going to make it for the first time, we’re there with them [to review] other changes before we lock in that final design.”

Next up: Hypersonic testing. The Pentagon’s innovation arm tapped GE Aerospace to develop a hypersonic test bed as part of the Hypersonic and High-Cadence Airborne Testing Capabilities, or HyCAT, program. The award follows one for a prototype in 2023. The first flight is targeted for 2028.
- “This is a significant milestone for our hypersonics team,” where “we’re the prime, but we’re also providing a dual-mode ramjet,” which can make the vehicle go faster and further, while “working with a number of other platforms to provide an all-up round to support this high-cadence hypersonic testing capability,” Steve “Doogie” Russell, VP and general manager of GE’s Edison Works, told reporters.
- But the company isn’t interested in developing a weapons system, Russell said.
- “This is a case where we do have the ability to be the full integrator for this test bed project, but we’re really focused on being a propulsion solution provider across this spectrum of activity. Same thing with the low-cost small-engine side of things.”
- The engine-maker is working with several other companies, but declined to name them or discuss product ranges.
- GE Aerospace also plans to use the solution to test other payloads, including engine upgrades, said Dean Modroukas, general manager of hypersonics.
- “The best way to assess hypersonic systems is to make sure that you’ve got plenty of time in an operating mode that’s relevant for things like thermal equilibrium, maneuverability,” Modroukas said. “HyCat is the second step of what we’re doing to develop a test bed and test capability that allows us to bring our engines into flight. So we’re always looking forward in terms of ways that we can learn quickly and through testing both on the ground, but end of the day, in a relevant environment, is [that] you want to be in the air.”
One more engine-related thing: The Navy certified Rolls-Royce’s mtu series 4000 and 2000 marine engines to power autonomous surface vessels.
