US Air Force’s Secretive AIM-260 Air-To-Air Missile Finally Unveiled.

Washington DC: May 2026: United States Airforce’s new AIM-260 Joint Advanced Tactical Missile (JATM) has been unveiled. Flight testing of the JATM is known to have started years ago, but it has never been seen publicly before now. The missile is expected to augment and ultimately replace the venerable AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) in the United States service.

On the 13th of May, at the Eglin Air Force Base in Florida, an F/A-18F Super Hornet from Air Test and Evaluation Squadron 31 (VX-31) was the first to be spotted carrying the AIM-260 on the fuselage station outboard of its right engine intake. The jet also has a modified FPU-13/A drop tank with an infrared search and track (ISRT) sensor on its centerline station, as well as flight data pods on its wingtips.

Eglin is routinely used as a staging point for U.S. military aerial weapons testing, as well as other aviation research and development and test and evaluation work. The base is situated right next to extensive over-water ranges over the Gulf of Mexico, off the coast of the Florida panhandle. When it comes to the AIM-260, the pictures confirm the design is very minimalist, at least externally, with only four fins at the tail. Unlike the AIM-120, it has no mid-body control surfaces, or even strakes running along the sides. The JATM’s overall configuration reflects optimisation for maximum speed and range.

The JATM in this case looks to have a live high-explosive warhead, as indicated by a yellow band at the front end of the body. There are also two black bands toward the rear, which could point to the location of the missile’s rocket motor. The nose cone has a distinct light gray color compared to the rest of the predominantly white body. There are square markings at various points at the rear of the body, which are often seen on aerial munitions and aircraft during testing to help with visual tracking, as well. Overall, the AIM-260 looks entirely in line with what had previously been depicted in official renderings of the JATM, both in terms of its design and markings.

The US Navy is developing the AIM-260 in cooperation with the Air Force. In the past, officials have explicitly cited the growing reach of Chinese air-to-air missiles, and the PL-15 in particular, as key drivers behind the JATM program. China continues to develop and field more capable AA missiles. A boost in maximum range is therefore known to be a central requirement for the AIM-260, which is reportedly designed to hit targets out to at least 120 miles, if not further. Another known requirement for the AIM-260 is to have a form factor that is roughly the same as the AIM-120, making it easier to integrate on existing aircraft. Details about the JATM otherwise remain limited.

Overall, the JATM program, which traces back to 2019, remains largely classified. As noted, flight testing of AIM-260 has been underway for some time and has already included multiple live-fire shots. There has also been movement in recent years to get the missile into production and fielded operationally.

Navy Super Hornets, along with US Air Force F-22 Raptors, are expected to be the first types to fly operationally armed with AIM-260s. The missiles will surely be integrated onto a host of other aircraft, including the Air Force’s future F-47 and whatever design the Navy might choose to become its sixth-generation F/A-XX fighter.

What the projected timeline might be for the AIM-260 entering operational service now is unclear. When the program first emerged publicly in 2019, the goal was for the missiles to be fielded in 2022. There were reports late last year that JATM had suffered a new three-month delay due to funding issues, based on a fact sheet distributed by some members of the US House Committee on Armed Services. However, the committee subsequently said that the information was incorrect.
