The fiscal year (FY) 2025 US Navy (USN) budget requests include USD16.2 billion for the procurement of 75 aircraft, modifications, spares, and support equipment, including 13 F-35Cs, 13 F-35Bs, and 15 CH-53Ks, according to budget documents released on 11 March.

However, the FY 2025 request represents a slight financial retreat for the USN, which requested USD17.3 billion in FY 2024 for 88 aircraft, including 19 F-35Cs and 16 F-35Bs.

In addition, the USN now plans to rephase the development of F/A-XX across the Future Years Defense Plan (FYDP), budget documents show.

“We’re still committed to the F/A-XX,” Rear Admiral Ben Reynolds, deputy assistant secretary of the navy for budget and director of the USN Fiscal Management Division, said during an 8 March media briefing of the proposed budget.

“We’re rephasing as the technology matures,” he said.

The USN plans to buy 82 F-35Cs and 82 F-35Bs across the FYDP, the budget documents show.
