Last week we walked you through the sustainment data fight simmering between Boeing and the Air Force over the T-7A Red Hawk. Seven days later, the Government Accountability Office showed up with receipts.

GAO's Weapon Systems Annual Assessment, released July 2 and first unpacked by Air & Space Forces Magazine on July 7, contains a date that should make everyone at Boeing St. Louis wince: January 2029. That is the new target for the T-7A's full-rate production decision. Last year's edition of the same report said January 2027. Two years, gone, in one publishing cycle.

"Since our last assessment, the T-7A program reported that it is experiencing significant delays in the completion of developmental testing," the GAO wrote. Auditors traced the slip to three culprits: extra engineering analysis, fewer flyable jets than planned thanks to shortages of maintenance personnel and spare parts, and software that keeps taking longer to finalize than anyone budgeted for.

The Word Nobody Wants to Hear: Concurrency

Here is the part that stings. The Air Force approved Milestone C on April 23 and announced it in early May — a $219 million contract for the first 14 production Red Hawks, with lots of talk about "phased" approvals and "active management." Jets are being built right now. But per GAO, most developmental testing will not wrap until April 2028, and lower-priority test requirements will run to May 2029.

That means production and testing overlap for years. GAO has a word for that — concurrency — and a warning to go with it: the practice "often results in cost overruns and schedule delays." Translation: if flight test finds a problem in 2027, the Air Force may own a ramp full of jets that need retrofits.

There is more. A key system-level test that links the T-7's ground-based training system to a jet in flight — the party trick that is supposed to make this whole training ecosystem revolutionary — is now not expected until July 2027. That is more than a year after the production green light and almost three years later than originally planned.

The Air Force did not push back. The service told Air & Space Forces Magazine it concurred with GAO's assessment and confirmed the developmental testing delays forced a replan, which produced the new 2029 full-rate date.

Boeing, for its part, deferred all comment to the Air Force. Given that the company has reported more than $2 billion in losses on its fixed-price T-7 contract, silence may be the cheapest thing it has produced on this program.

Why the Air Force Keeps Pushing Anyway

The math explains the urgency. The Air Force plans to buy about 351 T-7As at roughly $28 million per tail to replace a fleet of some 476 T-38C Talons — trainers whose basic design predates the moon landing by nearly a decade. The T-38 cannot replicate anything a student needs to fly an F-22 or F-35, and keeping its 1960s-era J85 engines alive is its own expensive saga, as we have covered before.

So the service is threading a needle: accept programmatic risk on the T-7 to shed the operational risk of flying a 60-year-old jet with student pilots in it. That is a defensible trade. It is also exactly the kind of trade GAO exists to flag, because history says concurrency bills always come due.

There is real progress to point to. The first Red Hawk reached Air Education and Training Command in December 2025. AETC qualified its first T-7 instructor pilots in June. The Air Force says the jet remains on track for initial operational test and evaluation this year, with 46 ground-based training simulators headed to five AETC bases over the next decade.

But step back and the pattern is hard to ignore. Full-rate production was once planned for 2022. Then 2023. Then Milestone C slid to 2026. Now full rate is 2029 — eleven years after Boeing won the $9.2 billion T-X competition with a digitally designed jet that was supposed to rewrite how fast America builds airplanes.

The first T-7A Red Hawk arrives at Air Education and Training Command, January 2026.

The Red Hawk will almost certainly be a fine trainer when it arrives in numbers. The question GAO keeps asking, politely and annually, is what it will cost to get there — and whether the jets rolling off the line today will match the jet that finally exits testing in 2028. Two more years of concurrency will answer that. We will be watching in January 2029, assuming that date holds. Recent history suggests you should not bet your per diem on it.
