Approximately $715 billion in defence spending is being requested, including for new aircraft purchases and advancing new programmes like Next Generation Air Dominance (NGAD) and the B-21 Raider stealth bomber.
For the F-35 programme, the US Air Force, Navy and Marine Corps are collectively asking for funds to purchase 85 new aircraft, including all three variants of the fighter jet.
USAF wants funding to buy an additional 12 F-15EX fighter jets. The service has already received funding for eight F-15EXs in the 2020 Fiscal Year budget and a dozen more in the budget for the 2021 Fiscal Year.
The service is also looking for $1.5 billion to support its NGAD programme, an increase of roughly $623 million compared to the funding USAF received for NGAD previously.
The service's goal, at present, is to buy at least 145 Raiders in the coming years from prime contractor Northrop Grumman.
