The US military still faces a looming capability gap in moving Army medium-weight weapon systems by air within a combat theater, the Government Accountability Office warned in a report Thursday. GAO said “only” the C-17 is currently capable of transporting heavier equipment, such as armored Strykers and MRAPs, within theater, as these are “too large and bulky” for C-130s. Yet, C-17s cannot transport these vehicles “into austere, short, or unimproved landing areas,” according to GAO. While the Air Force-Army joint future theater lift concept to replace older C-130s will address this shortfall, JFTL fielding is not expected until 2024, based on current planning, said GAO. This means that C-17s may have to be used more in tactical heavy lift roles to mitigate—but not fill—this gap between 2016 and when JFTL is available, potentially impacting the C-17’s “primary role as a strategic airlifter,” said GAO.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
