Context

The US Navy has introduced the AIM-174B, an extremely long-range air-to-air missile, in the Indo-Pacific, aiming to counter China’s aerial dominance.
This deployment is part of a broader strategy to enhance US power projection as tensions in the region escalate.

Details

It represents a significant upgrade in the Navy's air-to-air combat capabilities, building on the body of the Standard SM-6 missile and integrating technology from the AIM-120 AMRAAM seeker.

Development and Purpose: The AIM-174B was unveiled in 2024, with its first flight occurring in the same year. It is intended to fill the gap left by the retirement of the AIM-54 Phoenix, providing carrier-based fighters like the F/A-18E/F Super Hornets with the ability to engage targets at extended ranges.
Performance: The missile is designed to achieve a top speed of Mach 3.5 and has an estimated maximum range of 300 kilometers. This range exceeds that of the AIM-120 AMRAAM and places the AIM-174B among the most capable air-to-air missiles in the world.
Technology: The AIM-174B utilizes an active radar homing seeker, derived from the AIM-120, which allows for precise targeting at long distances. It is also expected to be integrated within the Naval Integrated Fire Control-Counter Air (NIFC-CA) architecture, working in tandem with platforms like the E-2D Hawkeye, F-35 fighters, and AEGIS combat systems.

The introduction of the AIM-174B significantly enhances the U.S. Navy's ability to conduct long-range air-to-air engagements, particularly in complex threat environments.
This capability is crucial for maintaining air superiority, especially in contested regions where adversaries possess advanced anti-air systems.
The missile's development aligns with broader U.S. military efforts to modernize its aerial warfare capabilities, ensuring that carrier air wings can effectively counter emerging threats well into the future.
