Nevada, August 31 - Boeing has recently unveiled a new rendering of its F/A-XX concept, a proposed sixth-generation fighter for the U.S. Navy, suggesting design similarities with its F-47, which is under development for the U.S. Air Force’s Next Generation Air Dominance (NGAD) program. Revealed at the Tailhook Symposium, the F/A-XX rendering depicts a sleek, stealth-oriented aircraft partially obscured by clouds, with its rear section hidden, making it difficult to discern specific features like tail configuration or control surfaces. The F-47, designed to succeed the F-22 Raptor, is a long-range, air-superiority fighter with a combat radius exceeding 1,000 nautical miles and a top speed above Mach 2, incorporating advanced stealth technologies and a new adaptive propulsion system. In contrast, the F/A-XX is tailored for carrier-based operations, intended to replace the Navy’s F/A-18E/F Super Hornet and EA-18G Growler, with a focus on a 25% range increase over existing strike fighters and a derivative engine rather than the F-47’s cutting-edge powerplant. This proposal indicates Boeing’s strategic intent to leverage technological advancements from the F-47 to streamline development and reduce costs for the Navy’s distinct NGAD program, despite the differing operational requirements of land-based and carrier-based fighters.

The F/A-XX rendering showcases a cockpit design similar to the F-47’s, though with a notably smaller radome, suggesting adaptations for naval requirements, such as enhanced survivability in anti-access/area-denial environments and compatibility with Nimitz-class and Gerald R. Ford-class aircraft carriers. Boeing’s earlier concepts for the F/A-XX, dating back to 2009 and updated in 2013, emphasized a tailless, twin-engine stealth fighter available in manned and unmanned configurations, with a weight class around 40,000 pounds. The obscured rendering at Tailhook aligns with this lineage, potentially incorporating canards or thrust vectoring to balance stealth and maneuverability, though these details remain speculative due to the image’s limited visibility. The F-47, by comparison, is presumed to feature a tailless design optimized for stealth, with a wider radome possibly supporting canards for enhanced control. Boeing’s approach contrasts with Northrop Grumman’s F/A-XX proposal, which features a sharp nose and air intakes above the wing roots, emphasizing stealth with a flowing, organic design reminiscent of the YF-23. The competition between Boeing and Northrop Grumman, following Lockheed Martin’s elimination in March 2025, underscores the high stakes for securing the Navy’s contract, with Boeing investing approximately $2 billion in new facilities, including a combat aircraft assembly site in St. Louis, to support both the F-47 and F/A-XX programs.
The Navy’s F/A-XX program, part of its own NGAD initiative, is distinct from the Air Force’s program despite sharing some technological developments. It aims to deliver a multirole strike fighter capable of air combat, ground attack, surface warfare, and close air support, complementing the F-35C Lightning II and unmanned systems like the UCLASS. However, the program faces challenges, as the Pentagon’s fiscal 2026 budget request allocated only $76 million to F/A-XX compared to $3.4 billion for the F-47, signaling a prioritization of the Air Force’s fighter due to concerns about the defense industry’s capacity to develop two sixth-generation fighters simultaneously. This funding disparity has placed F/A-XX in a state of limbo, with development paused to preserve resources while completing initial design work. Boeing’s CEO of Defense and Space, Steve Parker, has pushed back against these concerns, asserting the company’s capacity to pursue both programs concurrently, leveraging its significant investments in advanced manufacturing and engineering talent. The F/A-XX’s requirements, including a 25% range increase and maximum sensor connectivity for real-time battlefield integration, highlight the Navy’s focus on versatility and survivability in contested environments, setting it apart from the F-47’s air-dominance mission.
Boeing’s F/A-XX proposal, drawing on F-47 design elements, reflects a pragmatic approach to meeting the Navy’s needs while capitalizing on existing technological advancements. The shared design philosophy could reduce development timelines and costs, a critical factor given the Pentagon’s budget constraints and the high cost of sixth-generation fighters, with the F-47 estimated at $300 million per unit. However, the distinct operational demands of carrier-based aircraft, such as reinforced structures for catapult launches and arrested landings, necessitate significant modifications, as evidenced by the F-35’s variants, which share only 20% parts commonality between land- and carrier-based models. The F/A-XX’s development trajectory remains uncertain, with Congressional support and Navy advocacy pushing for progress, while the Pentagon’s focus on the F-47 could delay contract awards. Boeing’s rendering, strategically unveiled to highlight design synergies, positions the company as a frontrunner in the Navy’s competition, but the outcome hinges on resolving funding disputes and proving industrial capacity. The eventual winner will shape the future of U.S. naval aviation, ensuring carrier air wings remain effective in high-threat scenarios through the 2030s and beyond.
