WASHINGTON — Boeing’s MH-139A Grey Wolf helicopter will enter output later on than expected, a U.S. Air Power application government explained Tuesday.
The Grey Wolf software was in the beginning scheduled for a Milestone C selection by the close of fiscal 2021, which would result in the start of small price first production.
Nevertheless, ongoing delays in certifying the plane with the FAA will drive the assistance to thrust off the milestone, claimed Col. William Rogers, the Air Force’s application govt officer for intelligence, surveillance, reconnaissance and distinctive functions forces.
“We are in the procedure of revisiting our acquisition system baseline, and will be briefing the [service acquisition executive, Darlene Costello] in the near long run,” he instructed reporters in the course of a media roundtable.

The MH-139A is a militarized variation of Italian aviation business Leonardo’s AW139 business helicopter, which has currently been certified by the European Union Aviation Security Company. Nonetheless, the Grey Wolf’s military services-specific technologies require to be tested and accredited by the Federal Aviation Administration.
The Air Force and Boeing underestimated how lengthy it would acquire to get supplemental type certifications (STCs) for the MH-139, which are important to begin developmental screening and make a creation decision, Rogers mentioned.
On major of that, Boeing is also owning to redesign one of the sensor fairings on the front 50 % of the aircraft, which have been found to affect the airflow to the helicopter’s pitot tubes — perhaps top to incorrect airspeed readings that can result in a crash.
“There’s pitot tubes on both equally sides of the aircraft, so in certain problems, the pitot tubes would not have the identical airspeed readings,” Rogers mentioned. “Boeing is ideal now in the system of testing the redesign. They have a few of solutions and they are accomplishing the enterprise testing now.”
The Gray Wolf has now acquired just one supplementary kind certification and will get one more two before Christmas, claimed Matt Beck, the Air Force’s MH-139A procedure application supervisor.
“That will get us into [developmental tests], which is great. Then we can definitely commence generating development on the plan and tests our armed forces products,” he mentioned. “The other STCs will near in FY22.”
The Air Pressure intends to buy 84 MH-139As to substitute the UH-1N Huey. The Gray Wolf will consider on missions these as checking intercontinental ballistic missile fields, conducting search and rescue, and transporting VIPs in the countrywide cash location.
Boeing won a $2.38 billion organization, preset-price award for the Huey replacement plan in September 2018 soon after publishing a proposal that clocked in at $1.7 billion lessen than the program’s original estimate. The organization been given an first $375 million for the initially 4 helicopters and the integration of armed service-unique merchandise required for the AW139 to satisfy the Air Force’s specifications.
The assistance purchased 8 MH-139As in FY21 and predicted buying an additional eight Gray Wolf helicopters in FY22. On the other hand, for the duration of the FY22 spending plan rollout, Air Force officers declared that the company would pause Gray Wolf procurement that 12 months to permit for FAA certification.
In December 2019, Boeing sent the 1st Gray Wolf helicopter to the Air Pressure, and the support established up its initial MH-139A detachment at Duke Field, Florida.
