The Air Force is seeking $5.3 billion in fiscal 2023 to continue upgrading its ageing facilities around the world.
Almost half of this is in the form of large construction projects
"These actions take urgently needed steps to improve the defence ecosystem and construct resilient facilities and infrastructure."
The Air Force Department launched its "Infrastructure Investment Strategy" three years ago.
The Air Force's major military construction spending is expected to fall as the service determines how to repurpose existing facilities for future needs.
Nearly 40 major projects are proposed for construction, with more than half of them starting from scratch.
Tinian Island in the Northern Mariana Islands has aircraft parking, fuel tanks, and other airfield features.
