U.S. Navy Nears F/A-XX Sixth-Generation Fighter Decision as Boeing and Northrop Battle for Contract.

The U.S. Navy is nearing a decision on its F/A-XX sixth-generation carrier fighter, with Boeing and Northrop Grumman remaining in competition ahead of an expected August 2026 downselect, according to Defense IQ’s 2026 International Fighter Aircraft Global Market Report. Long-range threats are increasingly forcing U.S. carriers to operate farther from contested areas, heightening the urgency of fielding an F/A-18 replacement that can preserve carrier air superiority and long-range strike capability across the Indo-Pacific.

F/A-XX is expected to provide greater range, survivability, and combat persistence than the F/A-18E/F Super Hornet, giving the U.S. Navy greater freedom to project air power from safer distances. China is the principal source of this operational pressure, as its expanding missile forces, increasingly capable sensor networks, integrated air defenses, and advanced combat aircraft increase risks to carrier strike groups and reinforce the need for greater combat radius, survivability, and networked air-superiority capabilities.

The F/A-XX is being developed as the U.S. Navy’s future carrier-based air-superiority fighter for operations from Nimitz- and Gerald R. Ford-class aircraft carriers. Expected to enter service during the 2030s while complementing the F-35C, F/A-XX is intended to give carrier air wings the range, survivability, networking, and integration with uncrewed aircraft needed to sustain offensive operations across an increasingly contested Indo-Pacific.

The operational problem is straightforward. As anti-ship missiles, integrated air defenses, electronic warfare, and long-range sensing expand, U.S. carrier strike groups may need to remain farther from hostile coastlines while still generating offensive air power. A longer-range fighter would let the U.S. Navy preserve air superiority and strike options without requiring the carrier itself to operate as deep within the most heavily contested threat envelope.

The report traces the F/A-XX requirement to U.S. Navy planning work that began in 2008, with an Analysis of Alternatives completed in 2019. The program entered a much more uncertain phase in 2025, when Pentagon officials reduced its priority relative to the U.S. Air Force’s F-47 and raised concerns about whether the U.S. aerospace sector had sufficient engineering and production capacity to mature two sixth-generation fighters concurrently.

That concern matters because Boeing is already the prime contractor for the F-47. The U.S. Air Force awarded Boeing the F-47 engineering and manufacturing development contract in March 2025, placing the company at the center of U.S. efforts to replace the F-22 Raptor with a new air-dominance fighter designed to operate with Collaborative Combat Aircraft, advanced sensors, secure communications, and next-generation propulsion.

A Boeing victory in the F/A-XX competition would therefore concentrate both principal U.S. sixth-generation crewed fighter programs within the same manufacturer. Such an outcome could create opportunities for engineering commonality and a larger long-term production base, but it would also place considerable pressure on Boeing’s combat-air workforce, development infrastructure, and supplier network as the company attempts to mature two highly demanding aircraft programs.

A Northrop Grumman victory would produce a different industrial structure by dividing the U.S. Air Force and U.S. Navy programs between two prime contractors. Northrop Grumman withdrew from the U.S. Air Force NGAD prime competition in 2023 but has remained involved in the U.S. Navy contest, making the F/A-XX decision more significant for maintaining multiple U.S. industrial centers capable of designing and integrating advanced combat aircraft.

Lockheed Martin is no longer part of the competition. According to the Defence iQ report, the company was removed from the F/A-XX contest in 2025 after its proposal reportedly failed to meet U.S. Navy requirements, leaving Boeing and Northrop Grumman as the remaining contenders.

Funding illustrates how close F/A-XX came to a much deeper slowdown. The Pentagon’s FY2026 request reduced development funding to only $74 million, effectively delaying the program and postponing a contract decision. Congress moved in the opposite direction, providing substantially greater support for the program. According to the report, congressional action included funding figures of $454 million and a subsequent $897 million allocation, with total FY2026 funding calculated at approximately $972 million. The precise relationship between these figures depends on how the report accounts for requested, authorized, and appropriated funds.

The congressional intervention matters because delaying F/A-XX would create a capability problem that extends beyond fighter replacement. The U.S. Navy expects its Super Hornet fleet to reach the end of its service life during the 2030s, while the F-35C alone is not intended to provide every element of future carrier air superiority. Without a new long-range crewed fighter, the U.S. Navy carrier air wing could face increasing difficulty generating offensive reach from outside the most dangerous anti-access zones.

The U.S. Navy is consequently seeking more than another fighter with improved aerodynamic performance. F/A-XX is expected to operate as part of a broader network of sensors, weapons, and uncrewed aircraft, allowing carrier aviation to distribute sensing and combat effects across a larger battlespace. This mirrors the U.S. Air Force’s approach with the F-47 and Collaborative Combat Aircraft, although the U.S. Navy requirement adds the constraints of carrier launch, recovery, deck handling, and maritime operations.

The Defence iQ report identifies crewed-uncrewed teaming as one of the defining trends in future fighter development. It argues that next-generation combat aviation increasingly depends on combining survivable crewed fighters with autonomous adjuncts that support intelligence, surveillance, and reconnaissance, electronic warfare, decoy operations, and additional weapons carriage.

For F/A-XX, this could allow the U.S. Navy to expand the effective reach and combat mass of a carrier air wing without relying exclusively on additional high-cost crewed fighters. Uncrewed aircraft operating forward of the carrier-based fighter could extend sensor coverage, complicate enemy targeting, support electronic attack, and potentially carry weapons, while the crewed aircraft remains responsible for mission command and the most complex tactical decisions.

The industrial challenge is therefore inseparable from the operational requirement. Sixth-generation combat aircraft demand specialized expertise in low-observable design, advanced propulsion, thermal management, sensor fusion, electronic warfare, software engineering, and secure networking. Developing the F-47 and F/A-XX concurrently requires sufficient capacity not only at the prime-contractor level but also across many of the same engine, electronics, materials, and weapons suppliers.

This is why the F/A-XX selection has consequences well beyond which company receives the U.S. Navy contract. The decision will help determine whether the United States maintains competing centers of combat-aircraft design expertise or increasingly consolidates future fighter development around fewer companies and supplier networks.

The challenge is amplified by the scale of U.S. combat-air modernization. Washington is simultaneously financing the F-35, expanding F-15EX procurement, developing the F-47, moving Collaborative Combat Aircraft toward acquisition, and maintaining major investments in advanced weapons, propulsion, and electronic warfare. 

For the U.S. Navy, the strategic value of F/A-XX ultimately rests on whether it can preserve carrier combat power at the distances imposed by an increasingly contested Indo-Pacific operating environment. A fighter capable of operating farther from the carrier, sharing targeting data across dispersed forces, and working with uncrewed aircraft could give commanders greater freedom to keep high-value ships and support aircraft outside the most dangerous threat zones while still generating offensive missions.

That makes F/A-XX more than a replacement for the F/A-18E/F Super Hornet. It is part of the U.S. Navy’s effort to ensure that the aircraft carrier remains an effective offensive instrument as the threat environment becomes increasingly shaped by long-range precision weapons, persistent sensing, and advanced air-combat systems.

The August 2026 downselect identified by the Defence iQ report could therefore become one of the most consequential U.S. Navy aviation decisions of the decade. Selecting Boeing or Northrop Grumman will determine the industrial leadership of the U.S. Navy’s future fighter, but the larger question is whether Washington can finance, engineer, and produce F/A-XX alongside the F-47 without overstretching the industrial base needed to deliver both.

If the United States succeeds, the two programs could provide complementary sixth-generation air-dominance capabilities tailored respectively to land-based U.S. Air Force and carrier-based U.S. Navy operations. If industrial-capacity constraints, funding pressures, or schedule delays force further postponements, the U.S. Navy could enter the 2030s with a widening gap between the Super Hornet's retirement profile and the reach required to keep carrier air power effective across the Indo-Pacific.
