The T-7A Purple Hawk superior jet coach received’t obtain preliminary operational functionality till early 2027, having slipped from its authentic aim of 2024 and a newer timeline of 2026, Air Pressure acquisition government Andrew Hunter mentioned April 21. The delay stems from postponement of the Milestone C low-rate manufacturing determination, ensuing from points found in testing associated to the ejection seat and extra.
In an e mail transmitted by an Air Pressure spokesperson, Hunter informed Air & House Forces Journal that “as a consequence of points found within the early growth and check section of this system, the Air Pressure is delaying its Milestone C determination to provoke the purchase of T-7A manufacturing plane. By extension, this can shift the T-7A program’s preliminary operational functionality (IOC) into the spring of 2027. We’re pursuing threat discount actions to mitigate a few of these schedule challenges.”
The Air Pressure and Boeing crew accomplished a sled check of the ejection seat in February and are set to conduct a taxi check “inside the subsequent a number of weeks,” Hunter mentioned. These assessments will hopefully present a path to resolving the ejection seat issues, he added.
The escape system bumped into hassle when testing confirmed that for individuals on the low finish of the peak/weight vary, ejection from the T-7 posed a threat of significant harm. Trade sources have mentioned, nevertheless, that the manikins used to check ejection forces could have been improperly instrumented.
The T-7A program used new methods like digital engineering and digital design to dramatically shorten the standard time to go from preliminary drawings to first flight.
“In consequence, we now have recognized and mitigated points earlier within the growth section, previous to formal flight testing” and earlier than a manufacturing determination, Hunter mentioned. “This considerably reduces concurrency on this system and avoids extra expensive delays from discovery later in growth, after a manufacturing determination.”
Nonetheless, the issues found—together with a “wing rock” problem—have pushed again the Air Pressure’s bold timeline to get the coach in service.
The Air Pressure acknowledged final week the T-7A possible received’t get the inexperienced mild for low-rate preliminary manufacturing till February 2026, but it surely couldn’t at the moment estimate what impact the delay would have on IOC. The manufacturing determination marked a 14-month slip from the replace to this system schedule in late 2022.
The primary manufacturing plane now won’t be delivered till December 2025. Three of the 5 production-representative plane obligatory for flight check are full, and each Boeing and the Air Pressure anticipate formal flight testing of these airplanes will start within the coming months.
The T-7A has additionally been troubled by provide and labor scarcity points.
Boeing and USAF are “assured enhancements and up to date testing are yielding a secure and efficient escape system,” an Air Pressure spokesperson mentioned April 14.
The Air Pressure eliminated all T-7 manufacturing funds from its fiscal 12 months 2024 funds request, saying the slip within the low-rate preliminary manufacturing meant manufacturing funds should not wanted within the coming fiscal 12 months.
The slip within the T-7A’s IOC date will now nearly absolutely require the Air Pressure to additional prolong the service of a few of its 60-plus-year-old T-38 superior jet trainers, which proceed to obtain structural modifications and cockpit enhancements.
The Air Pressure plans to purchase 351 T-7As and has choices to purchase as many as 475.
In current days, members of Congress have expressed considerations to the Air Pressure about coach shortages inflicting delays in pilot manufacturing and deficits in pilot manning ranges, significantly in fighters.
