This week, the AIM-242 Malice, a LRAAM (Long Range Air-to-air Missile), was announced by the U.S. Navy.
We don’t know much about the missile, but what we do know is that it was quietly worked on by Raytheon and is capable of hitting targets over 250 nautical miles (463 kilometers) away, according to Navy reporting. Its 13.5″ diameter and aerodynamic profile were built for range as well as for the ability to be carried by fighters with internal weapons bays.

The missile was officially announced on August 22, 2026, at the Tailhook symposium in Reno, Nevada. The Navy announced there that the weapon was already in flight testing and being developed for deployment on the Boeing F/A-18E/F Super Hornet, the Lockheed Martin F-35, and the future F/A-XX program.

It’s thought that the development of the AIM-424 comes from the Long-Range Engagement Weapon (LREW) special access program first disclosed to the public in 2017. At the time, the US Air Force was looking for a two-stage air-to-air missile that could be carried in the internal weapons bay of a stealth fighter (F-35 or F-22), a similar use case to AIM-424.
The range of the AIM-424 has been quoted as around 250 nautical miles, which is similar to the publicly reported upper limits of the AIM-174B Gunslinger, which is a derivative of the sea-based RIM-174B Standard Extended Range Active Radar Missile (ERAM, Standard Missile-6, or SM-6). What the AIM-424 brings to the table is versatility, as the Gunslinger is a much larger missile and currently only known to be carried by the Boeing F/A-18E/F Super Hornet.

A U.S. Navy Boeing F/A-18F Super Hornet (BuNo 166673) of Air Test and Evaluation Squadron 9 (VX-9) flies over the Point Mugu Sea Range in Southern California (USA), 24 September 2024. The aircraft carries two AIM-9X Sidewinder missiles, three AIM-120 AMRAAM and four AIM-174B long-range air-to-air missiles, an infrared search and track system (IRST) in a modified drop tank on its centerline, as well as an ATFLIR targeting pod on its left cheek station.
The U.S. Air Force and Navy have both put a priority on extending the engagement range of its fighters as the U.S.’s potential enemies extend the range of their armaments. China fields the PL-17 with a reported range of over 300 miles.

An important caveat to all of this is that the published range figures are usually much larger than what the missile can reasonably expect to make a hit on a target. The range is tested using high altitude, in good weather conditions, against a non-maneuvering target. The tests don’t use any sort of jamming or defensive countermeasures. Taking these factors into account, the range these that any air-to-air missile can expect to score a kill is much shorter than what is published.
In air-to-air combat, you have a concept of the No-Escape Zone (NEZ). This is the volume of space in which the target cannot defeat the missile through pure kinematics (turning away, accelerating, diving, or any combination of those) no matter how well the pilot flies. Outside the NEZ, the probability of kill (Pk) falls off steeply. For many conventional solid-rocket missiles (most of them), the NEZ is often roughly one-third (or less) of the advertised maximum range.
A related concept is the practical effective engagement range against an alert, maneuvering fighter that is using countermeasures. That distance is usually even shorter than the pure kinematic NEZ once you factor in real-world degradation factors.
Most missiles that use solid rocket fuel burn their fuel very quickly, most medium range within the first 10-12 seconds of launch. After that, burnout the missile is coasting. It is a finite amount of energy that it must manage all the way to the target. Course corrections and drag come into play, and at very long range, the missile could simply lose all energy and “go ballistic”, keeping a straight course and falling to the Earth.
While these factors are all important it shows why companies are continuing to push the envelope and produce these long range systems, as the more you can push the ideal range, the longer range that the missile will have under less than ideal combat situations where the enemy is jamming the missile, and using ever tool he has to evade.
