Three NATO Countries Bolster Defenses: Belgium, Italy, and Romania Acquire New AIM-9X Missiles for F-35

NATO Strengthens Air Defense with Joint Procurement

The US State Department has just approved an arms sale to NATO’s procurement agency, NSPA, valued at nearly 700 million DKK. The deal covers 96 AIM-9X Block II/II+ Sidewinder missiles along with training, logistics, and documentation. Belgium, Italy, and Romania are the first recipients—an example of how the alliance is pooling its efforts through collective solutions.

What Makes the AIM-9X Stand Out?

The Sidewinder family has been in service since the 1950s, but the latest version is anything but outdated. The AIM-9X combines imaging infrared seekers with thrust vector control, allowing the missile to change direction even during extreme maneuvers. The newest Block II+ version can even receive data in-flight, making it possible to retarget after launch—a nearly dreamlike capability in modern air combat.

Romania Receives the Largest Share

Romania, which is in the process of transitioning from older MiG-21 and F-16 fighters to the F-35, will receive a total of 64 missiles. This ensures that the country’s upcoming 5th-generation aircraft have a short-range missile capability on par with NATO’s leading air forces. Italy and Belgium are supplementing their existing F-35 fleets—for Belgium, even eight additional missiles represent a tangible strengthening of its readiness.

A Message to Russia and China

The AIM-9X is designed to counter both advanced fighter jets like the Su-35 and J-20—as well as swarms of drones. Its ability to function even in environments rife with electronic warfare makes it a vital component in NATO’s layered defense. As one European security expert puts it: “This type of weapon is not just for close combat—it’s an investment in credible deterrence.”

More Than an Arms Deal

The acquisition through the NSPA allows for the establishment of a joint missile stockpile, shared across NATO countries. It reduces costs, eases logistics, and sends a clear message that the alliance is united. For NATO’s adversaries, the message is clear: Even small nations can rapidly draw on advanced firepower when the need arises.
