The US Military's AIM-260 Air-to-Air Missile Unveils Its Mysteries

Reference News Network reported on May 20 The U.S. "Theater" channel website published an article on May 15 titled "The Mysterious AIM-260 Air-to-Air Missile Finally Unveiled," authored by Joseph Trevithick. The full text is translated as follows:

The first physical image of the U.S. military's new AIM-260 Joint Advanced Tactical Missile has been made public. It is reported that flight testing for this missile began years ago, but it has never been publicly displayed before. This missile is expected to enhance and eventually replace the U.S. military's current AIM-120 Advanced Medium-Range Air-to-Air Missile.

On May 13, photographer Jonathan Tweedy captured several U.S. Navy test aircraft taking off from Eglin Air Force Base in Florida. Among them was an F/A-18F Super Hornet from the Navy's Air Test and Evaluation Squadron 31, which had an AIM-260 missile mounted on the external pylon of its right engine air intake.

The images taken by Tweedy confirm that, at least from the outside, this missile has a very minimalist design, featuring only four tail fins at the rear. Unlike the AIM-120, it lacks a mid-body control surface and even does not have canard wings on the sides, reflecting an overall layout optimized for maximum speed and range.

From this image, the AIM-260 appears to be equipped with a high-explosive warhead, as indicated by the yellow stripe at the front of the missile body. There are also two black stripes at the rear of the missile body, which may indicate the position of the missile's rocket engine.

Compared to the white of the missile body, the nose cone of the missile is a distinct light gray. There are square markings in different positions on the rear of the missile body. Such markings are commonly seen on aerial munitions and aircraft during testing, aiding in visual tracking.

The U.S. Navy is collaborating with the Air Force to develop the AIM-260 missile.

Significantly increasing the maximum range is one of the core requirements for the AIM-260. Reports indicate that its design goal is to strike targets at least 120 miles (approximately 193 kilometers) away or even further.

Another known requirement for the AIM-260 is that its dimensions are roughly the same as the AIM-120, making it easier to integrate into existing aircraft.

For a long time, advanced rocket engines using high-energy propellants have been seen as a viable approach to significantly extend the range and speed of the AIM-260 beyond that of the AIM-120 without increasing the missile's size.

In addition to manned aircraft, the AIM-260 is also expected to be equipped on future stealth drones, such as those being developed under the U.S. Air Force's Collaborative Combat Aircraft program.

The AIM-260's rocket engine is likely to feature a dual-pulse design, maintaining energy throughout the entire flight envelope to further increase range and significantly enhance terminal maneuverability. In the absence of additional control surfaces, thrust vector control capability is also a necessary condition to provide the missile with sufficient agility.

The AIM-260 is likely to be equipped with an active electronically scanned array radar seeker. In the face of an expanding array of countermeasures, having multi-mode seeker capabilities—potentially including infrared imaging and passive radio frequency guidance—will be highly valuable. However, it is still unclear whether the current model possesses this feature, and it may be introduced in later variants.

Advanced networking capabilities will be a key feature, allowing the missile to obtain additional target information from a range of third-party sources. This is particularly important for engaging targets beyond the detection range of the launch platform's own sensors, and it can also allow the launching aircraft, especially stealth aircraft, to avoid turning on their own radar, thereby reducing the risk of detection. Multiple networked Joint Advanced Tactical Missiles could even coordinate to execute attack missions.

Overall, the Joint Advanced Tactical Missile program, which can be traced back at least to 2019, remains largely classified. As mentioned, flight testing for the AIM-260 has been underway for some time, including multiple live-fire tests. In recent years, there has also been progress in the missile's production and actual deployment. (Translated by Tu Qi)
