F-35 vs. F-47: The Pentagon’s High-Stakes Fighter Funding Battle

Key Points – The Pentagon’s 2026 defense budget proposal is forcing difficult trade-offs between legacy systems and next-generation platforms amid rising global tensions.

-The Air Force has reportedly slashed its F-35 procurement request to boost funding for the new F-47 sixth-generation fighter.

-This inter-service rivalry is mirrored in Europe, where disputes between France and Germany are plaguing the Future Combat Air System (FCAS) sixth-generation program.

-Meanwhile, the push toward automation is accelerating with projects like DARPA’s unmanned “Defiant” warship and the use of FPV drones in major military exercises, highlighting a period of intense technological and budgetary transition for Western defense planners.

Pentagon Finances Under Fire Amid Russia, Iran Escalations

As global tensions soar, the Pentagon’s 2026 defense budget is a topic of hot controversy.

Flat spending plans are forcing difficult trade-offs between legacy systems and next-generation ambitions, as internal rivalries and international friction threaten key weapons programs.

At the Paris Air Show this week, Europe’s troubled Future Combat Air System (FCAS) was on full display, less for its aeronautical prowess than for the political turbulence plaguing it.

French defense giant Dassault Aviation and German-Spanish partner Airbus are again clashing over who controls the sixth-generation fighter program.

Airbus’s Jean-Brice Dumont said Dassault’s was a leader in the sector, but complained that rows over intellectual property and workshare risk could impede the project.

Western Division Amid Global Threats

Could Europe present a united defense front despite these squabbles?

As it stands, the FCAS timeline could extend to 2045 or even later.

Meanwhile, the UK-Italy-Japan-led Global Combat Air Programme (GCAP) is moving more briskly, with a prototype already unveiled.

At the same time, the U.S. is charging ahead with Boeing’s F-47 sixth-gen jet, slated to enter service by 2029.

Hegseth Slammed by Congress

Back in Washington, Defense Secretary Pete Hegseth came under fire before the House Defense Appropriations Subcommittee for proposing a Pentagon budget that critics say doesn’t match the scale of global threats.

Notably, the Air Force is cutting its F-35 buy to fund its next-generation fighter. This is an unconventional move, but it surely underscores shifting priorities.

Boeing, riding high after securing the F-47 contract, is also lobbying to keep the Navy’s beleaguered F/A-XX program alive, insisting it can handle both projects. “From day one, our capital investment was for both programs,” said Boeing Defense CEO Steve Parker, directly rebuffing Secretary of the Navy John Phelan’s concerns over industry bandwidth.

With $5 billion already sunk into air-dominance facilities, Boeing is betting big—and taking public jabs at rival Lockheed Martin’s proposal for a “supercharged” F-35.

Automatic: No Longer the Future?

Elsewhere, automation is no longer the future but the battlefield present. DARPA’s experimental USX-1 “Defiant” vessel, part of the Navy’s NOMARS (No Manning Required Ship) program, and first-person view drone operations during African Lion 2025 exercises in Tunisia, hint at a robotic revolution in warfighting.

With U.S. forces training in live drone and AI-assisted warfare, the push toward unmanned dominance is accelerating: even as lawmakers remain split on how to fund it.

Finally, Boeing confirmed it’s close to finalizing the long-delayed VC-25B presidential aircraft. However, Trump’s directive to modify a Qatari-donated 747 as an interim “Air Force One” has drawn scrutiny.
