The Modified SM-6 "AIM-174B" The US Respond to The Russian and Chinese Hypersonic Air to Air Missiles

The AIM-174B appeared at the Rim of the Pacific (RIMPAC) exercises in Hawaii in June of 2024, carried by an F-18 Super Hornet, with new news on the end of last tests and its deployment in the US navy.

 

 The SM-6 was originally a surface to air missile launched by naval platforms. It is an effective solution for a long-range interception and has anti-ballistic capabilities, it plays an important role in the protective umbrella of any task force.
After the development of the new Russian R-37 M hypersonic air to air missile with a magnificent range up to 350 Km, the US had to bring a fast solution to counterpart these new threats.
 

The AIM-174B missiles are recognized for their long-range capabilities of more than 250 Km, with advanced seekers which make it very accurate when getting close to the targets and high subsonic speed of Mach 4.
It’s a good solution for filling the gap between it and the AIM-120 AMRAM which came with a maximum range of 180 Km.

Technical drawbacks of this new missile

 The AIM-174B is very large compared to the usual air to air missile and even compered to their Russian counter part, which make it very heavy on the aircrafts wings and prevent it to make sudden and aggressive maneuvers when needed, and already the navy aircrafts because they are already can’t tolerate a high Gs pull ups.

 

In the image compared to an AIM-120 AMRAAM the AIM-174 is twice longer and thicker.

 The integration of the missile in other fighters is limited due to volume, it doesn’t fit in the suit of the 5^th gen fighters like the F-35, F-22 Raptor which annihilate their stealth capabilities, and the relatively small aircrafts like the F-16.
The AIM-174 makes a limit on the aircraft’s payload, for now the F-18 Super Hornet can hold a total of just 4 missiles in both wings.

The benefits for US military presence in the pacific and Europe

 The integration of the AIM-174B enhances the U.S. Navy's air-to-air combat capabilities while also tackling emerging threats like hypersonic missiles and anti-access/area denial systems, especially in the pacific front which the lang range kills is very crucial above the seas.

A new direction for air-to-air battels

 The nature of Beyond Visual Range (BVR) engagements is evolving significantly due to advancements in missile and radar technology, enabling combat at extremely long distances, ranging from 300 to 400 kilometers.
