Machina Labs' RoboCraftsman panel flew on a repaired Air Force C-17

Why it matters

The C-17 repair puts Machina Labs' no-tooling approach into a safety-sensitive aerospace job. Its larger test is whether one successful panel can become repeatable factory output.

Machina Labs says its replacement left-nose panel, formed by RoboCraftsman, flew on a crewed U.S. Air Force C-17 when the repaired aircraft returned to flight on July 30, 2026, at Wright-Patterson Air Force Base. Co-founder and CEO Edward Mehr highlighted the milestone on August 29, one month after the flight.

The part was made with RoboCraftsman, Machina Labs' robotic manufacturing platform. The system progressively shapes sheet metal from digital designs, avoiding the dedicated dies and molds that make conventional forming expensive for a single replacement part. The Air Force described the panel as the first part produced through incremental sheet forming to fly on an Air Force platform.

For Mehr, the flight is the clearest operational test yet of an idea he and materials engineer Babak Raeisinia began pursuing when they incorporated Machina Labs in September 2019: factories should be programmable enough to switch between complex metal parts without rebuilding the production line around each design.

Mehr arrived at that thesis through software and rockets. He interned at Microsoft and Google before joining SpaceX as a software engineer, then became program manager for large-envelope metal 3D printing at Relativity Space. In a June 25 interview published by Miru Robotics, Mehr said visiting SpaceX's factory reconnected him with childhood trips to industrial sites with his father. Manufacturing offered a more tangible problem than the advertising systems he had encountered in software.

Raeisinia brought the materials side. He holds a Ph.D. in materials engineering from the University of British Columbia and previously led computational materials-science and exploratory work at aluminum producer Novelis, according to a biography published by the National Science Foundation's HAMMER Engineering Research Center. Their pairing gave Machina Labs a founder base spanning robotic controls, factory software and the behavior of metals under forming.

A one-off part stranded a mission aircraft

The repair began with a March 4, 2025 storm at Perot Field Fort Worth Alliance Airport. Wind and hail damaged a C-17 assigned to the 445th Airlift Wing after two private Bombardier Challenger jets were blown into the military transport, according to the Air Force Life Cycle Management Center's account.

The Air Force said the C-17 flew back to Ohio with a temporary nose-panel repair that Boeing had qualified and the service had approved, and with its landing gear down. Maintenance personnel repaired the door and fuselage damage, but the left-nose panel had to be replaced.

That isolated component created a familiar sustainment problem. The Air Force account says Boeing determined that suppliers would not build dedicated tooling for a single panel. After another repair attempt failed, officials projected at least one year of storage and another year of repair work. The grounding affected one of nine C-17s that the wing considered mission-essential.

The 445th Maintenance Group turned to the Air Force Rapid Sustainment Office, which had installed a Machina Labs system at its Ohio operations center. Engineers from the University of Dayton Research Institute joined the work, while Boeing and the maintenance group handled the aircraft installation.

The public accounts differ on when panel production began. The Air Force dates the broader effort to January 2026, while Machina Labs says manufacturing with RoboCraftsman began in March and finished in May. The Air Force says it conducted fit checks and panel testing, completed a final fit check in April, and had Boeing and Air Force maintainers install the panel in July.

After a landing-gear test and adjustments around the nose, the C-17 returned to flight on July 30. Air Force program manager Mary Schuler said the effort reduced a repair measured in years to one completed in months. Col. Karen Gharst, commander of the 445th Maintenance Group, said the Rapid Sustainment Office delivered a panel for fit checking in just over a month.

The result should be read narrowly. A specific panel passed the testing and approvals required for installation and flight on this C-17. That outcome does not amount to blanket certification for every part RoboCraftsman could form, or for every aircraft program Machina Labs hopes to serve.

Mehr's factory thesis reaches the flight line

In the Miru Robotics interview, Mehr said RoboCraftsman uses two industrial robots to incrementally form sheet metal and can switch tools for trimming and scanning. He described welding as a future capability. Mehr also said cells could be reprogrammed to produce defense components and aircraft parts without product-specific physical changes to the factory floor.

The C-17 repair illustrates that model. Boeing found that suppliers would not build dedicated tooling for the replacement panel, while the Rapid Sustainment Office already had access to a programmable forming system. Legacy aerospace fleets often remain in service after original production lines and supplier networks have moved on, leaving maintainers to source obsolete, low-volume parts.

That market is also shaping Machina Labs' expansion. On February 4, Machina Labs announced a $124 million Series C from Woven Capital, Lockheed Martin Ventures, Balerion Space Ventures and Strategic Development Fund. Machina Labs said the capital would help build a 200,000-square-foot U.S. factory capable of housing as many as 50 RoboCraftsman cells.

Machina Labs previously raised a $32 million Series B co-led by NVentures and Innovation Endeavors, bringing its cumulative funding to $45 million in 2023. Including the Series C, Machina Labs has disclosed at least $169 million in venture financing.

Investors funded Machina Labs to move beyond demonstrations and operate production infrastructure. The C-17 repair offers evidence that RoboCraftsman can produce hardware for a safety-sensitive, operational aerospace use case with the aircraft manufacturer, military maintainers and government engineers involved. The company still has to repeat that result across more components, programs and factory cells while maintaining the consistency aerospace manufacturing requires.

The planned factory could hold dozens of cells, compared with the system used for this repair. Scaling that operation will require RoboCraftsman to turn a successful one-off job into routine output.

The first crewed flight does not complete that transition. It gives Mehr and Raeisinia something more useful than another prototype: a part that solved an expensive maintenance problem and flew.
