The United States has approved a major arms deal worth $318.4 million for Denmark, involving the sale of AIM-9X Block II Sidewinder tactical missiles and related equipment. The approval was announced by the U.S. State Department, which confirmed that the deal will help Denmark improve its defense systems and strengthen coordination with NATO allies.
U.S. Approves Major AIM-9X Missile Sale to Strengthen NATO Ally
The U.S. Defense Security Cooperation Agency (DSCA) said the package includes up to 340 AIM-9X Block II missiles and 34 tactical guidance units, along with essential equipment and services. In addition, the deal covers training aids, support gear, spare parts, software, and logistics assistance, ensuring smooth operation and maintenance.
Moreover, engineers designed the AIM-9X Sidewinder as a modern, high-tech missile for air-to-air combat. Fighter jets launch it to intercept and destroy enemy aircraft with great precision. Thanks to its speed, agility, and accuracy, it remains one of the most trusted short-range weapons used by the U.S. and its allies.

Denmark already uses the AIM-9X system as part of its F-35A Lightning II fighter jet fleet, which is one of the most advanced aircraft in the world. With this new purchase, the country will be able to expand and modernize its missile stockpile, ensuring it can defend its airspace more effectively and work closely with other NATO partners during joint missions.
Boosting Denmark’s Security and NATO Cooperation
This sale is part of a larger effort by the U.S. to support the defense capabilities of allied nations in Europe. By supplying Denmark with the latest generation of AIM-9X missiles, the U.S. aims to enhance NATO’s collective security at a time of increasing global tensions.
According to the DSCA, the proposed sale will “improve Denmark’s ability to meet current and future threats” while also helping the Danish Air Force maintain a strong and ready defense posture. The deal will not only strengthen Denmark’s national security but also ensure that its military remains fully compatible with U.S. and NATO systems.
The AIM-9X missiles will serve multiple roles in Denmark’s defense strategy. They will primarily equip the country’s F-35A fighter jets, giving them the ability to detect, track, and engage enemy aircraft more effectively. Denmark will integrate the missiles into its ground-based air defense systems to add an extra layer of protection against aerial threats.

The U.S. government named RTX Corporation, formerly known as Raytheon Technologies, as the principal contractor for the project. RTX, one of the world’s leading defense manufacturers, has produced Sidewinder missiles for decades and will handle the production, delivery, and initial training for the sale.
Officials stated that the sale will not change the basic military balance in the region, describing it as a defensive upgrade rather than an aggressive action. However, it is still an important signal of ongoing U.S. support for NATO allies amid evolving global security challenges.
The AIM-9X Sidewinder: A Trusted and Advanced Weapon
The AIM-9X Block II Sidewinder is one of the world’s most advanced short-range air-to-air missiles. Engineers built it to give fighter pilots an edge in modern combat. Using infrared heat-seeking technology, it can lock onto and track enemy aircraft even during evasive maneuvers.
Unlike older versions, it has an improved guidance system that strikes from wider angles and longer ranges, with mid-flight updates from the aircraft’s computer for greater precision. The missile is lightweight, easy to maintain, and works with F-35A, F-16, and F/A-18 jets, allowing NATO forces to train and operate together seamlessly.
For Denmark, which has been steadily upgrading its air force, the addition of these missiles represents a major step forward in its ability to defend national and regional airspace. The move also shows Denmark’s continued commitment to meeting NATO defense standards and contributing to European security.

Beyond its technical strengths, the AIM-9X has also earned a reputation for reliability and effectiveness. It is currently used by more than 25 countries around the world, including many key U.S. allies. Its proven track record in numerous training and real-world operations makes it a preferred choice for nations looking to modernize their air defense systems.
By approving this sale, the United States reinforces its long-standing defense partnership with Denmark and reaffirms its support for NATO’s shared goal of collective security and readiness. The deal ensures that Danish forces remain well-equipped to face emerging threats and continue working side by side with allies in maintaining peace and stability in the region.
