Key Points and Summary: The U.S. Air Force is developing the secretive AIM-260 Joint Advanced Tactical Missile (JATM) to counter long-range weapons from China, notably the PL-17 missile.
Key Point #1 – Designed by Raytheon, the AIM-260 maintains compatibility with existing AIM-120 platforms but features an aerodynamic shape, fewer fins, and an extended rocket motor for significantly enhanced range.
Key Point #2 – Using advanced propellant technologies, the missile may exceed 120 miles in range. AIM-260 will complement the AIM-120D, forming a versatile air-to-air missile mix.
Bottomline: Ultimately, paired with stealth fighters like the F-22 and F-35, AIM-260 aims to provide a decisive tactical edge for future air superiority against emerging threats.
Meet AIM-260: The Secret Missile America Is Building to Counter China
The new and somewhat secretive AIM-260 Joint Advanced Tactical Missile (JATM), an air-to-air missile Raytheon is developing for the U.S. Air Force, made an appearance recently in an informational booklet released for the public by the Naval Air Systems Command’s (NAVAIR’s) Program Executive Office for Unmanned Aviation & Strike Weapons.
Here is what we know.
Curtain Pullback
The AIM-260A Joint Advanced Tactical Missile is a highly secretive Special Access Program developed to counter the increasingly long-range advanced weapons wielded by foreign adversaries, particularly China.
Based on the provided image, the new AIM-260 JATM looks to be optimized for low drag and long range.
Importantly, it will have the same form factor—the missile’s footprint or shape—as the older AIM-120. This will ensure compatibility with systems that use the older missile.
The new rocket’s motor also seems to be longer than the AIM-120’s—indeed, it appears to constitute almost half of the AIM-260A’s length.
Meant as a Stop-Gap
The AIM-260 JATM is not yet known to be in service with the U.S. Air Force. This means that until the JATM gets online, a bridge weapon to use in the longer ranges will be needed—one that will be an advanced version of the AIM-120 air-to-air missile. The AIM-120D is an interim measure that operates to a greater range than its predecessor.
Ultimately, the AIM-260 and an advanced AIM-120 derivative may be employed together, offering the Air Force a high/low mix of capabilities in which the longer-range AIM-260 strikes targets from extreme ranges in the initial stages of an engagement, and the low-range missile is retained for use at closer ranges.
The Advanced Medium-Range Air-to-Air Missile (AMRAAM), an AIM-120 derivative, likely has a range of about 100 miles, whereas the AIM-260’s range would, in all likelihood, exceed 120 miles.
Advanced Propellant
A more aerodynamic design that has fewer fins as well as a larger engine section is certainly one way to increase range. However, the AIM-260 Joint Advanced Tactical Missile’s propellant may also have a higher energy density than current alternatives.
In 2023, the Naval Air Warfare Center Weapons Division (NAWCWD), announced it had made important advances in propellant.
“The Next-Generation Highly Loaded Grain project team has matured the technology and seeded the development of future mission-modular propulsion systems that can increase weapon ranges by up to 1.5x while maintaining inner boundaries for short-range and time-critical missions,” NAWCWD explained.
Another range-extending option could be a smaller warhead design that would leave slightly more internal space for additional propellant.
In addition, the AIM-260 does not retain the four fins along the rocket’s body used by some previous air-to-air missiles, further decreasing the new missile’s drag.
Key Concern
Of high concern for the Air Force is the PL-17, an extremely long-range air-to-air missile in service with the People’s Liberation Army Air Force. At about 20 feet long, the PL-17 is some 7 feet longer than the AIM-120 family of missiles. It also boasts an incredibly long range of 250 miles.

The PL-17 is intended to target and engage high-value targets, rather than taking out single fighters jets. Its target list would likely include Early Warning and Control aircraft, as well as tankers and logistical aircraft.
At this stage, very little is known about the AIM-260 Joint Advanced Tactical Missile, other than it will offer a potentially significant boost in range to the fighter jets that equip it.
When integrated with U.S. stealth fighters like the F-22 Raptor or the F-35 Lightning II, the AIM-260 JATM would be a very potent air-to-air missile indeed. For now, we wait.

China today isn’t ready for anything now being very secretly planned by the pacific forces, but it’s not because of those AIM-174s.
China, under the stupidly foolish xi jinping, has concentrated all its eggs literally in one basket and a surprise lunge by admiral sam paparo would surely send china back to the flintstone era.
Today, the western media, most especially reuters, are hollering and howling and bawling loudly that the china economy is failing, faltering, collapsing and ailing.
In response to those shrieks, the feekin’ feekin’ dumb stupid xi is rushing major ‘stimulus’ measures forward not realising china’s eastern coast is already way over-developed and overcrowded.
That is the achilles heel of china and once it’s targeted by paparo, it’s game OVER for china. Game over.

Our military needs “razors” as fighting men and our military needs the most lethal & effective technology our scientists, engineers, and manufacturing can fashion and produce.
That said, making the article into a boasting & bragging session of how we’re going to pound China seems to ignore the overall military situation regarding China.
(Okay, describing weapons systems to inform readers of our technological development and achievements is a mission of this website and I respect the mission as a worthwhile endeavor… America needs an informed citizenry.)
There is an ideological purity test and institutional inertia among pro war commentators: you must support the idea the United States shall defend Taiwan or you aren’t really serious about military affairs.
This is false, you can be serious as a heart attack about military affairs and reject the warhawk posture towards China & Taiwan because it leads the United States into an unwinnable war.
China’s military industrial base is entirely focused on the military requirements of ‘reunification’ of China… Taiwan fully incorporated as a province of China.
The quality of technology is obviously crucial, but so is quantity and the proposed field of battle.
China may have lesser technology… although, evidence suggests this gap is closing fast. But the numbers they produce is substantial and Taiwan and environs is strategically & tactically within China’s sweet spot, 100 miles off their mainland, while it’s almost seven thousand miles off the U. S. mainland, about five thousand miles from Hawaii and 1,700 miles from Guam.
It’s the one region of the World where China can beat the United States straight-up because of their strategic & tactical advantages of Taiwan being right next to their coastline.
To ignore this reality is reckless in the face of the known dangers.
I’m happy at the development of super air-to-air missile technology, no doubt about that.
But attaching it to the reckless defense of Taiwan is not the right approach.
