An early design concept of the Boeing F/A-XX.

Next Generation Air Dominance, previously called F/A-XX, is a development and acquisition program for a future sixth-generation air superiority fighter to replace the United States Navy's F/A-18E/F Super Hornet beginning in 2025. A requirement was first identified in June 2008. Besides having the F/A-XX replace the Super Hornet, the fifth generation F-35 Lightning II is also replacing it.[1]


In April 2012, the Navy issued a formal request for information for the F/A-XX. It calls for an air superiority fighter with multi-role capabilities to replace the F/A-18E/F Super Hornet and EA-18G Growler aircraft in the 2030s, while complementing the F-35C Lightning II and UCLASS unmanned aircraft, that can operate in anti-access/area-denial environments. The aircraft must be capable of operating from Navy Nimitz-class and Gerald R. Ford-class aircraft carriers. Primary missions include air combat, ground attack, surface warfare, and close air support. Other missions can include air-to-air refueling, reconnaissance, surveillance, and target acquisition (RSTA), and electronic attack. There is consideration for manned, unmanned, and optionally manned platforms.[2]

The F/A-XX is being pursued as F/A-18 Super Hornets will reach the end of their 9,000 hours of service life by the early 2030s. Aside from the option of buying more F-35Cs, the F/A-XX is seeking to create a new aircraft to replace the Super Hornet's capability and mission set. An open architecture design is desired, so different sensors, payloads, and weapons can be plugged in for a specific mission, and be able to be moved around for multiple different missions on different days or different sorties. Building everything into one plane can become expensive. The resulting open architecture design is likely to take shape depending on which style of new propulsion system is presented by the aircraft industry. Unmanned, manned, and optionally manned systems are being considered. An Analysis of Alternatives (AOA) was expected to begin in 2014, with a fighter to be introduced around 2030. Just as the F-35C will replace aging F/A-18 Hornets and complement Super Hornets, the F/A-XX will replace aging Super Hornets in the 2030s and complement the F-35C.[3]

On 9 September 2014, the Navy announced that an AOA for the FA-XX aircraft would begin in 2015, and that they were calling on industry to participate in technical interchange meetings (TIMs) as a precursor focusing on several areas including affordability and modifying current Super Hornet and F-35C jets. Other meeting will focus on building new aircraft to meet the requirement, developing a family of systems (FoS) approach, and discussing mission systems, avionics, and new next-generation weapons systems; information on the projected technology readiness level of each proposal by 2020 is requested. Navy officials are not only meeting with established development teams like Lockheed Martin, Boeing, and Northrop Grumman, but "outside the box" efforts including not focusing on manned or unmanned platforms and FoS approaches are to reduce costs and make it more effective. One option could create a minimum cost F/A-XX that uses high cost, high performance weapons to defeat threats; according to the Navy's Naval Integrated Fire Control-Counter Air (NIFC-CA) battle network concept, an individual platform would not need to have a full suite of sensors and rely on off-board data-linked information from other platforms to provide targeting information and guide weapons launched from the platform. Rather than be a Super Hornet or F-35C that can engage on its own, the F/A-XX could be a "truck" with longer-range weapons with linked fire control. The F/A-XX platforms will be made to carry missiles, have power and cooling systems for directed energy weapons, and have sensors that can target small radar cross-section targets; cyber warfare platforms at a tactical level as part of a FoS are being explored. While the Navy is working with the U.S. Air Force on a next-generation tactical fighter, there is significant disagreement over the Air Force's claims that adaptive-cycle jet engine technology, where the ratios of bypass and compression airflow can be made variable to improve efficiency, can be scaled to benefit a carrier-based fighter.[4][5]


The Boeing F/A-XX concept design as of 2013.

In July 2009, Boeing unveiled a sixth-generation fighter concept the F/A-XX requirement. It was a two-seat, twin-engined tailless jet with a blended wing. Although it has a tandem cockpit, Boeing said it can be manned or unmanned depending on the mission. The fighter concept is in the 40,000 lb (18,000 kg) weight class. The Northrop Grumman X-47B that was chosen for the UCAS-D program has also been proposed for the F/A-XX effort.[1][6]

In a 31 May 2011 disclosure to Congress, the Department of Defense revealed that they were considering buying more F-35C fighters to replace 556 Super Hornets. The DOD plans to replace the older F/A-18C/D Hornets with 220 Lightning IIs. In March 2011, a Navy analysis of alternatives showed that they may buy more F-35C aircraft, develop a new platform, or do both for their NGAD fighter program.[7]

Boeing unveiled an updated F/A-XX sixth-generation fighter concept in April 2013. The concept is a tailless twin-engine stealth fighter available in manned and unmanned configurations. It has canards, which usually compromises the frontal radar cross-section, but the lack of a tail shows an emphasis on all-aspect stealth. It also has diverterless supersonic inlets similar to the F-35. The manned version seems to have restricted rearward visibility without the aid of a sensor.[8]
