The US Navy has awarded Raytheon a contract valued at $736m for the production of the Block II variant of the AIM-9X Sidewinder missiles.

This contract ensures the continuation of manufacturing of what it claims to be the world's most advanced short-range air-to-air and surface-to-air missile. It will also address hardware obsolescence and upgrading for superior performance and reliability.

The AIM-9X Block II missile with advanced infrared-tracking capabilities offer a short-range solution for both air-to-air and surface-to-air combat scenarios.

It is designed for seamless integration with a wide array of modern aircraft, enhancing layered defence systems such as the National Advanced Surface-to-Air Missile System (NASAMS).

Raytheon plans to undertake the production work for this contract across various locations within the continental US and is expected to continue until 2029.

Raytheon Naval Power president Barbara Borgonovi said: “AIM-9X remains the weapon of choice for short-range air-to-air and surface-to-air missile defence, and worldwide customer demand is strong.

“We're investing, innovating, and partnering with our US Navy customer to significantly increase our AIM-9X production capacity starting with orders next year.”

The AIM-9X missile programme is a joint initiative led by the US Navy in collaboration with the US Air Force.

Currently, AIM-9X is employed by more than 30 allied and partner nations in their defence arsenals.

Earlier this year, the Czech Republic joined the list of international customers by agreeing to procure the missile for their F-35 aircraft.

The AIM-9X Block II missile features updated electronics, including a lock-on-after-launch capability using a new weapon datalink. This supports beyond visual range engagements.
