If war is won by speed and range, then the U.S. Air Force has a problem and Lockheed Martin believes it has a solution. The company’s suggested “Ferrari F-35” upgrade is marketed as a means of bridging the growing performance gap with China’s Chengdu J-20, a stealth fighter that already outperforms the Lightning II in both areas. The solution: infuse the fifth-generation F-35 with a line of sixth-generation technologies originally designed for Lockheed’s losing effort in the Air Force’s Next Generation Air Dominance (NGAD) competition.
Lockheed head honcho Jim Taiclet has been candid regarding the ambition. We’re going to port a lot of our own NGAD R&D over to the F-35, he said, describing the goal as delivering 80 percent of the capability of a sixth-generation fighter at 50 percent of the cost. That capability package would be broad pilot-optional operation, new radar- and infrared-absorbing stealth coatings, structural refinements to reduce the rear-aspect radar cross-section, and integration of advanced weapons now destined for Boeing’s F-47 NGAD.
The stealth improvements extend beyond customary upkeep of radar-absorbing materials. Recent years have seen U.S. military testing of mirror-like coatings that scatter radar energy over bands, matched with infrared-suppressing layers to conceal engine heat signatures. Taicaut indicated “adjustments… on outer mold line… particularly around engine inlets and outflow nozzles” that would further lower detectability short of a complete redesign. These changes target one of the Lightning II’s known vulnerabilities: its rear-aspect radar return.
Perhaps the most radical element is autonomy. While the F-35 already demonstrates limited self-flying capability one jet famously flew for 11 minutes after a pilot ejected in 2023 Lockheed envisions a pilot-optional” mode. This would require advanced AI-assisted flight control, secure datalinks, and onboard decision-making algorithms akin to those in NGAD’s collaborative combat aircraft. Such independence might enable the F-35 to fly over high-risk regions without endangering a human pilot, or to coordinate fleets of unmanned vehicles in hostile skies.
Electronic warfare and networking enhancements are also core. The AN/APG-81 AESA radar, Distributed Aperture System, and Electro-Optical Targeting System are already providing the F-35 with a sensor fusion advantage, but Lockheed aims to amplify broadband jamming, cyber-resilient datalinks, and multi-domain orchestration. In recent conflicts, like the attack on Iranian nuclear sites in Operation Midnight Hammer, the ability of the F-35 to orchestrate many other platforms” from satellites to fourth-generation fighters was the decisive factor.
The urgency stems from hard numbers. The F-35A’s combat radius on internal fuel is about 669 nautical miles, versus the J-20’s estimated 1,100 nautical miles. The Chinese jet’s Mach 2.0 top speed also outpaces the Lightning II’s Mach 1.6. In beyond-visual-range combat, the J-20’s PL-15 missile may outrange the AIM-120 AMRAAM, while its larger airframe carries more internal ordnance. Analysts point out that although the F-35 is still superior in all-aspect stealth and sensor fusion, range and speed differences may be decisive in a Pacific war.
Lockheed’s schedule is ambitious. Taiclet sees within the span of two to three years” enough technology derived from NGAD to be incorporated for a “meaningful enhancement of capability.” But he warns against loading too much new equipment or too much new software onto the production line at once: “You cannot bring on too much new equipment or too much new software simultaneously… without affecting the production stream.” The upgrades would be staged, beginning with stealth coatings and outer mold line refinements, followed by autonomy and integration of advanced weapons.
The program also carries geopolitical significance. While the F-47 NGAD will probably not be available before 2029, the upgraded F-35 would be the sole Western fifth-generation fighter in production volume a “bridge” platform for a decade. Saudi Arabia and India are potential customers, although both are experiencing political and trade headwinds. For existing allies operating the Lightning II, the Ferrari package would provide continuing relevance into the 2030s, matching the speed of rivals’ advancements.
Whether the Pentagon will support such an overhaul is unclear. The F-35 program has been plagued by delays in its Technology Refresh 3 the hardware and software underpinnings of Block 4 upgrades and continues to be the subject of political debate. But in an age when air supremacy is increasingly a matter of who sees it first, shoots it first, and stays alive first, Lockheed’s Ferrari F-35 sales pitch is as much about strategic imperatives as it is one of engineering ambition.
