Trump Administration Explores ‘5th-Generation-Plus’ F-35: Integrating Lost 6th-Gen Tech to Bolster U.S. Air Dominance

In a bold pivot following Lockheed Martin’s setback in the Next Generation Air Dominance (NGAD) program, the company is pitching an upgraded “fifth-generation-plus” F-35 Lightning II stealth fighter to the U.S. government, incorporating technologies from its failed sixth-generation bid. As of September 12, 2025, Lockheed CEO Jim Taiclet revealed active high-level engagements with the Department of Defense (DoD), with expectations that the proposal could soon reach the White House under the Trump administration. This development comes amid President Donald Trump’s expressed interest in enhancing the F-35 platform, including a suggestion for a twin-engine variant, signaling a potential shift in America’s fighter jet strategy to prioritize cost-effective upgrades over entirely new platforms.

The proposal stems from Lockheed’s loss earlier this year to Boeing in the NGAD competition, now designated as the F-47, which is slated for operational status by 2029. Taiclet described the upgraded F-35 as a “Ferrari” version, aiming to deliver approximately 80% of sixth-generation capabilities at half the cost of a full NGAD fighter. Key enhancements include advanced stealth coatings to better evade radar and infrared detection, a more powerful engine, upgraded electronic warfare systems, new radar technology, expanded weapon bays, and even an optionally manned configuration allowing for unmanned operations. These features draw directly from research conducted for Lockheed’s sixth-gen concept, which emphasized automation, data fusion, and adaptive cycle engines for superior thrust and efficiency.

Trump’s involvement adds a layer of political momentum. In May 2025, the president voiced enthusiasm for an F-35 upgrade featuring two engines, a departure from the current single-engine design, though experts warn this could essentially require building a new aircraft, entailing decades of development and billions in costs. A former Air Force pilot familiar with the program likened it to a complete overhaul, potentially disrupting the F-35’s production line, which has already delivered over 1,000 jets worldwide. Nonetheless, Taiclet has expressed optimism, noting “encouraging feedback” from DoD officials and highlighting the fiscal prudence of retrofitting existing platforms amid constrained defense budgets. Lockheed envisions upgrading 1,000 to 1,500 of the remaining 2,300 ordered F-35s, with a focus on U.S.-bound units, and potentially expanding exports if classifications allow.
 This initiative aligns with broader U.S. efforts to maintain air superiority against rising threats from China and Russia, whose advancing stealth technologies demand rapid innovation. By integrating sixth-gen tech into the F-35, Lockheed aims to extend the jet’s relevance well into the 2040s, bridging the gap until the F-47 enters full service. Upgrades could roll out in phases to minimize production disruptions, including better integration with collaborative combat aircraft (drones) and enhanced networking for multi-domain operations. Taiclet projects meaningful capability boosts within two to three years, positioning the “5th-gen-plus” F-35 as a cost-effective alternative that undercuts the need for additional sixth-gen procurement. Turning to America’s top stealth fighters currently in production or testing, the landscape reflects a mix of proven fifth-generation platforms and emerging next-gen systems. The F-35 Lightning II remains the cornerstone, with over 1,000 units produced by Lockheed Martin and ongoing deliveries to the U.S. and allies.
As a multirole stealth fighter, it excels in air-to-air combat, ground strikes, and electronic warfare, with variants for conventional takeoff, short takeoff/vertical landing, and carrier operations. Its sensor fusion and low-observable design make it a fifth-gen leader, though software glitches and cost overruns have drawn criticism. The F-22 Raptor, built by Lockheed and Boeing, is another fifth-gen icon, though production ended in 2011 with 195 units delivered. Optimized for air superiority, it boasts supercruise capability (sustained supersonic flight without afterburners) and advanced avionics. While not in production, upgrades continue, including helmet-mounted displays and new weapons integration, keeping it relevant in testing and exercises against simulated peer threats. On the bomber front, the B-21 Raider, developed by Northrop Grumman, represents the latest in stealth technology. The second test aircraft took flight on September 11, 2025, from Edwards Air Force Base, accelerating the program’s testing phase.

Smaller than the B-2 Spirit, the B-21 can carry up to 30,000 pounds of conventional or nuclear payloads with intercontinental range. At least six are under production, with plans for 100+ to replace aging B-52s and B-1s. Its advanced stealth coatings and open architecture for rapid upgrades position it as a key asset for penetrating contested airspace. Looking ahead, the NGAD program, now the Boeing F-47, is in early development as the Air Force’s sixth-generation fighter. Designed for air dominance, it features adaptive engines, enhanced stealth, and integration with drone wingmen for collaborative combat. A demonstrator flew in 2020, and with the Pentagon’s FY2026 budget fully committed, prototypes are expected to advance testing toward a 2029 debut. Costs per unit could exceed $200 million, emphasizing modularity for future upgrades. The Navy’s F/A-XX, a carrier-based sixth-gen fighter, shares technologies with NGAD to expedite development.

It prioritizes extended range to counter anti-access/area-denial strategies, with adaptive engines boosting fuel efficiency and combat radius. While funding for F/A-XX was paused in favor of the Air Force’s F-47, testing of components continues, with full prototypes anticipated in the late 2020s.Speculative programs like the rumored F-45 Condor and hypersonic Mayhem drone add intrigue, though details remain classified. The F-45, potentially a stealth interceptor, has surfaced in unverified reports, while Mayhem focuses on reusable hypersonic strike capabilities. These efforts underscore America’s commitment to stealth innovation, blending upgrades to legacy systems like the F-35 with groundbreaking new designs.
As geopolitical tensions rise, the Trump administration’s potential endorsement of the “5th-gen-plus” F-35 could reshape procurement, balancing affordability with cutting-edge tech. With Boeing’s F-47 on the horizon and the B-21 taking flight, U.S. airpower remains poised to dominate.
