The gleaming 179,000-square-foot hangar built for Boom Supersonic at Piedmont Triad International Airport is mostly quiet these days. North Carolina has already poured more than $50 million into the site, originally pitched as the future production home of Boom’s Overture airliner, and now state and local leaders are left to decide how long they will keep betting on a high-flying private venture that has yet to take off in Greensboro. With a critical hiring deadline set for December 31, 2026, officials say the next stretch will reveal whether this gamble pays off for the Triad economy or sends them back to the drawing board.
The public tab so far
State lawmakers have already written sizable checks for the project. They set aside roughly $106.75 million to prepare the PTI site, including $56.75 million to reimburse construction work and $15 million for grading and site preparation, according to state budget documents from the North Carolina General Assembly. Additional local and state spending, along with payroll-based incentives and roadwork, pushed the overall public package higher. A detailed breakdown of promised support is available in subsidy tracking compiled by Good Jobs First.
A lease deadline and a jobs pledge
In return, Boom committed to hire 1,761 workers at the Greensboro site. The lease with the Piedmont Triad Airport Authority, however, comes with a hard benchmark: it allows termination if the company employs fewer than 500 people by December 31, 2026, according to The News & Observer. That date gives state and airport officials a clear legal checkpoint as Boom recalibrates its plans and looks for other ways to bring in money.
Boom’s pivot and fresh funding
Last December, Boom rolled out a new commercial line, a 42 megawatt “Superpower” natural gas turbine aimed at AI data centers, and said it had secured roughly $300 million to advance the engine core that will also underpin Overture, Business North Carolina reports. Company leaders say the turbine business is intended to generate nearer term revenue while work continues on the Symphony engine and Overture aircraft development.
Factory built, aircraft not yet
The showcase facility in Greensboro is ready on paper. Construction on the 179,000 square foot production hangar at PTI wrapped up in 2024, as reported by AviationPros. Boom has not yet built or tested Overture aircraft at the site, though. Instead, the company has focused on its XB-1 demonstrator, which has completed flight testing in California, and says it “looks forward to beginning Overture test production in North Carolina as soon as possible,” according to Boom Supersonic.
Officials weigh a choice
For now, local leaders insist the mega-hangar will not sit empty forever, whether Boom fills it or not. Piedmont Triad Airport Authority Executive Director Kevin Baker told reporters he has “absolute confidence the building could be filled anytime” and said other companies have already inquired about the space, as reported by The News & Observer. That optimism is tempered by reporting that Boom trimmed staff late in 2024, a development the paper summarized from the Wall Street Journal, which makes it more difficult to predict whether the company will hit its employment targets in Greensboro.
In the months ahead, officials say they will be watching Symphony engine milestones and hiring numbers as the clock ticks toward December 31, 2026. Boom has reaffirmed its aim to carry passengers by 2030, according to the company announcement. If the firm cannot meet the lease’s employment test, airport and state leaders will face a different kind of turbulence as they decide whether to recruit new tenants, repurpose the hangar, or try to renegotiate the deal.
