US Air Force F-47 sixth-generation fighter design target exceeds 1,000 nautical mile combat radius
Key Points
  • F-47's combat radius exceeds 1,000 nautical miles, superior to the F-22 and F-35A.
  • The F-47 is regarded as the US Air Force's first sixth-generation fighter, slated for first flight in 2028.
  • The F-47 will feature greater survivability and adaptability, supporting rapid update capabilities.
  • The aircraft's design focus is on air superiority and will operate collaboratively with drones.

The US Air Force is designing its sixth-generation fighter, the F-47, planning a combat radius exceeding 1,000 nautical miles (approximately 1,150 miles), capable of flying from base, completing a mission, and returning — a range that will surpass the F-22 Raptor and F-35A Lightning II. Brig. Gen. Timothy Helfrich, the Fighter and Advanced Aircraft Program Executive Officer at the Air Force Life Cycle Management Center, outlined these goals in an interview with the Mitchell Institute Aerospace Nation.

He described the F-47 as what the US Air Force considers the world's first sixth-generation fighter, and said the service aims to conduct a first flight in 2028, followed by entry into service contingent on development and testing progress.

The significance of combat radius lies in the fact that it is not a ferry range, but rather a measure of how far an aircraft can fly from its base, complete a mission, and return — a figure dependent on environmental conditions and fuel requirements. According to publicly reported data, the F-47's projected combat radius will be roughly 70% greater than the F-22's 590 nautical miles (approximately 679 miles) and nearly 50% greater than the F-35A's 670 nautical miles (approximately 771 miles). This gap is especially critical in the Indo-Pacific, where vast distances and China's long-range missiles threaten air bases, logistics hubs, and support aircraft.

The Importance of Combat Radius

A fighter capable of operating farther from its base will give commanders more force deployment options and may reduce the number of refuelings required for certain missions. For longer distances, extended patrols, or penetration into defended areas, tankers will still be needed.

F-47 Survivability and Adaptability

Helfrich said the F-47's survivability will be stronger than that of existing fifth-generation fighters, a formidable goal given that the F-22 and F-35A already possess stealth capabilities. The Air Force has not disclosed the F-47's radar cross-section or specific electronic warfare performance, so its advantages cannot yet be independently measured. Helfrich also emphasized the F-47's adaptability, stating the aircraft will enter service with a fully open architecture, enabling the Air Force to add software, sensors, and electronic warfare capabilities more quickly as threats evolve.

Upgrading existing fighters is complex, as demonstrated by the F-35A's Technology Refresh 3 and Block 4 efforts. Open mission systems are not unique to sixth-generation designs, as the F-15EX already employs them. The F-47's aim is to combine that flexibility with low-observable stealth performance.

The F-47 is the core crewed fighter in the Air Force's Next Generation Air Dominance program. Boeing secured the engineering and manufacturing development contract in March 2025. Previously disclosed goals include a top speed exceeding Mach 2 and a fleet of at least 185 fighters. The jet is expected to operate alongside collaborative combat aircraft — drones — to extend sensor coverage, carry additional weapons, and complicate enemy targeting. Unlike the multi-role F-35A, the F-47's design focus is on high-end air superiority. It also possesses stealth capabilities that the F-15EX and F-16 lack; the F-15EX can carry approximately 29,500 pounds of external stores.

Final quantities, costs, and timelines will depend on testing, production capacity, and future budgets. As China expands its fighter fleet, missile arsenal, and integrated air defense systems, the Air Force is counting on the F-47 to maintain a competitive edge in air superiority even as current fighters face growing limitations. Achieving that goal will mean translating ambitious requirements into an affordable aircraft.

The F-47's Importance to US Air Force Strategy

The F-47's design focuses not only on increasing combat radius but also on the demands of future combat environments. As China's military capabilities grow, the US Air Force urgently needs a fighter with higher survivability and flexibility to address increasingly complex threats. The F-47's open architecture will enable it to rapidly adapt to emerging threats, which is critical for maintaining air superiority. Additionally, the F-47's high-end air superiority design and collaborative combat capabilities with drones will further enhance US operational effectiveness in future conflicts.
