The U.S. Navy has revealed the AIM-424 Malice, a next-generation long-range air-to-air missile designed to extend the defensive reach of American carrier strike groups.

Malice was presented at the Tailhook Symposium in Reno, Nevada, and it is also known as the Long-Range Air-to-Air Missile (LRAAM). Naval officials have described the weapon as a major advance in range, lethality, and combat effectiveness compared with existing U.S. air-to-air missiles.

The missile is intended not only to engage enemy fighters but also to target bombers, airborne early-warning aircraft, tankers, and other platforms that could launch long-range anti-ship missiles against U.S. naval forces.

That mission reflects the growing importance of long-range weapons in the Indo-Pacific. Chinese aircraft and missile systems are increasingly capable of threatening ships from distances that could place them outside the engagement envelopes of some existing U.S. air-to-air weapons.

By moving the interception point farther away from the carrier, Malice could expand the defensive perimeter around U.S. naval formations and complicate the ability of an adversary to assemble and execute long-range attacks.

Two-Stage Design to Preserve Energy

The AIM-424 is a two-stage missile, according to reporting on the program, although the Navy has not disclosed detailed information about its propulsion stages or flight profile. The architecture is intended to provide extended reach while retaining sufficient energy for the missile to maneuver during the final phase of an engagement.

That distinction is important because maximum range does not necessarily represent effective combat range. A target can turn away, change altitude, use electronic countermeasures, or force an incoming missile to expend energy before reaching the terminal phase.

A two-stage architecture could help address some of those limitations by allowing the missile to use different propulsion phases during its flight.

The Navy lists the AIM-424 at 13.5 feet (4.11 meters) in length, 13.5 inches (0.34 meters) in diameter and 26.2 inches (0.67 meters) in wingspan. It weighs 1,500 pounds (680.4 kilograms), uses a solid-propellant rocket motor and carries a blast-fragmentation warhead. The Navy gives its range as in excess of 250 nautical miles (463 kilometers), although detailed performance parameters remain classified.

Malice is substantially larger and heavier than the AIM-120 AMRAAM. It is also broadly comparable in size to the AIM-174B, although the AIM-424 is slightly shorter and lighter. Its larger dimensions are consistent with its intended role as a specialized long-range weapon rather than a replacement for the entire U.S. air-to-air missile inventory.

The AIM-120D AMRAAM continues to provide established beyond-visual-range capability, while the AIM-260 Joint Advanced Tactical Missile is intended to provide advanced long-range capability while remaining compatible with internal weapons bays. The AIM-174B, derived from the SM-6 family, provides another extended-range option.

Malice appears to occupy the upper end of that layered system. Its value would be greatest against high-value targets whose destruction could prevent multiple weapons from ever being launched. A single engagement against a bomber, airborne early-warning aircraft, or tanker could potentially disrupt a much larger strike operation.

However, the missile’s effectiveness will depend heavily on the wider targeting network. Detecting, identifying, tracking, and continuously updating a target at extreme distances requires reliable sensors, communications, and data links, particularly in an environment where electronic warfare and communications disruption are expected.

The significance of Malice therefore cannot be measured by its advertised range alone. A missile capable of reaching more than 250 nautical miles still requires a sufficiently accurate firing solution, resilient communications and a sensor network capable of tracking a target throughout the engagement. In a heavily contested environment, the ability to maintain that kill chain could be as important as the missile’s propulsion or aerodynamic performance.

F-35C Integration Expands

One of the most significant aspects of the program is the missile’s integration with both the F/A-18E Super Hornet and F-35C.

Testing aboard the F/A-18E provides the carrier air wing with a platform capable of carrying multiple large missiles externally. Public imagery has shown four AIM-424s carried by a Super Hornet, highlighting the aircraft’s potential to provide substantial missile capacity. The F-35C offers a different advantage.

Public imagery indicates that the missile has been carried internally by the carrier-based stealth fighter. Internal carriage is particularly important because externally mounted weapons increase radar signature and can reduce the low-observable characteristics that allow the F-35C to operate closer to heavily defended areas.

The combination gives the carrier air wing two complementary options. In a future operational concept, F-35Cs could operate as forward, low-observable sensing and targeting platforms, while Super Hornets could carry larger numbers of missiles from positions farther from the threat.

Such an arrangement would allow the aircraft launching a missile to be different from the aircraft that initially detects or tracks the target.

If supported by the necessary sensors and data links, this cooperative engagement concept could become one of Malice’s most important advantages. A fighter does not necessarily need to rely solely on its own radar to employ a very-long-range missile if another aircraft or sensor can provide the necessary targeting information.

Integration across the F/A-18E/F and F-35C also indicates that the missile is being developed as part of a broader carrier aviation architecture rather than for a single aircraft.

The planned F/A-XX sixth-generation naval fighter is also expected to form part of that future architecture, potentially allowing Malice to remain relevant across several generations of U.S. naval aviation.

The central operational problem Malice is intended to address is the increasing distance from which American carriers can be threatened.

China’s anti-access and area-denial strategy relies on a combination of long-range missiles, surveillance systems, aircraft, ships, submarines, and other sensors designed to locate and threaten U.S. forces before they can approach contested areas.

Malice attacks one part of that system by providing an opportunity to engage the aircraft responsible for launching long-range weapons before those weapons are released. That could change the economics of fleet defense.

Instead of waiting for several anti-ship missiles to approach a carrier and attempting to intercept them individually, U.S. forces could potentially attack the aircraft responsible for launching them. Destroying or forcing those aircraft away could prevent multiple missiles from entering the fight.

The approach could also force Chinese strike aircraft to operate from greater distances, use additional escorts and electronic-warfare support, or adopt more defensive flight profiles. Those requirements could increase fuel consumption, reduce available weapons payloads and complicate coordination across a large strike force.

A larger defensive perimeter could also provide greater freedom for carriers to operate while maintaining air support over a wider area.

However, Malice would not independently defeat China’s wider strike network. Carrier survivability will continue to depend on layered air and missile defense, electronic warfare, deception, manoeuvre, distributed operations and the ability to maintain the sensors and communications networks needed to support long-range engagements.

The missile’s large size could also create its own challenges. Carrying more very-long-range weapons means sacrificing some capacity for smaller missiles or other weapons. The Navy will therefore have to balance exceptional range against magazine depth and the need to respond to larger numbers of less sophisticated threats.

Building on years of Long-Range Missile Development

The AIM-424 is not an entirely new effort to develop very-long-range air-to-air capability. The United States lost its dedicated carrier-based long-range interception capability with the retirement of the AIM-54 Phoenix in 2004.

The AIM-120 AMRAAM subsequently became the primary U.S. beyond-visual-range air-to-air weapon, but advances in Chinese missile technology increasingly challenged the assumption that American fighters would consistently enjoy a range advantage.

The development of China’s PL-15 and other long-range systems contributed to renewed U.S. interest in extending the range at which American aircraft could detect and engage high-value targets.

One important predecessor is the Long-Range Engagement Weapon (LREW), a two-stage interceptor concept associated with U.S. defense research during the middle of the 2010s.

Fiscal Year 2017 documentation referred to design and engineering work, kill-chain analysis, and a demonstration program. Earlier concept imagery showed a large two-stage missile being launched from an F-22’s internal weapons bay, reflecting an ambition to combine long range with compatibility with stealth aircraft.

The similarities between the earlier LREW concept and Malice suggest a possible technological or developmental connection, although the Navy has not publicly confirmed that LREW evolved directly into the AIM-424.

Industry involvement also points to continuity. RTX President Phil Jasper said the company’s Advanced Technology team was central to developing Malice, although the Navy has not publicly released the program’s full acquisition structure or all of its industrial partners.

The Navy’s disclosure therefore appears to represent the public emergence of a capability that has been shaped by years of classified research, propulsion development, engineering demonstrations and aircraft integration.

Testing involving an F/A-18E in April 2026 and subsequent F-35C weapons-bay fit testing indicate that the program had already progressed well beyond the conceptual stage before its public announcement.

Indo-Pacific Deterrence

The missile’s most important geopolitical implications are likely to emerge across the Taiwan Strait, South China Sea and wider Western Pacific.

A longer-range U.S. air-to-air weapon could force Chinese aircraft operating in support of maritime strike missions to account for a larger engagement zone.

High-value aircraft such as tankers and airborne early-warning platforms could face greater risk, while strike aircraft could require additional escorts and electronic-warfare support.

That could increase the complexity and logistical burden of Chinese operations. Longer missions require more fuel, tanker support, maintenance and crew endurance, while additional aircraft increase the overall size and detectability of a strike package.

The disclosure also sends a broader signal about the future of U.S. carrier aviation. The growing reach of Chinese anti-ship missiles has prompted questions about whether large aircraft carriers can continue operating effectively in the Western Pacific.

Malice suggests that the U.S. Navy is responding by extending the reach of the carrier air wing rather than relying solely on the carrier’s own defensive systems. The missile could therefore strengthen deterrence by increasing the potential cost of attacking U.S. naval forces.

At the same time, longer-range weapons can create new escalation risks. If tankers, airborne warning aircraft or command platforms become vulnerable at greater distances, an engagement involving those assets could be interpreted as the beginning of a broader offensive campaign.

This makes identification, command authority, communications resilience and escalation management increasingly important as engagement ranges expand.

China is also likely to adapt. Possible responses include longer-range air-to-air missiles, electronic countermeasures, decoys, stealthier aircraft, dispersed formations and efforts to attack the sensors and data links required to exploit Malice’s range.

The missile’s emergence should therefore be viewed as part of an evolving competition between weapons and the networks that support them.
