### US Deploys Long-Range AIM-174B Air-to-Air Missile Amid Rising Tensions in Indo-Pacific
The US has rolled out its advanced long-range air-to-air missile, the AIM-174B, which could potentially shift the power dynamics in the Indo-Pacific region amid rising tensions with China. Mounted on the US Navy’s F-18 Super Hornet, this missile boasts an operational range of approximately 400 km. The AIM-174B is a variant of the Raytheon SM-6 surface-to-air missile, widely used for anti-air, anti-ballistic, and anti-surface warfare.
The AIM-174B was first spotted during the Rim of the Pacific (RIMPAC) exercise, the world’s largest naval drill with 26 participating nations. The missile, seen attached to the Super Hornet, drew significant attention due to its potential to disrupt air power balance.
#### All About AIM-174B
The AIM-174B is the air-to-air adaptation of the SM-6 missile, leveraging the existing production lines for rapid availability. Unlike its surface-to-air counterpart, the AIM-174B weighs about 850 kg, lacking a booster motor. It travels at Mach 3.5, making it a formidable counterpart to the Russian Rh-37 Vympel and the Chinese PL-15 long-range missiles.
China’s PLA Navy has also introduced the advanced PL-17 missile, with a similar range of 400 km. The last long-range air-to-air missile in the US Navy’s arsenal was the AIM-54 Phoenix, retired in 2004. The development of the AIM-174B signals a return to Cold War-era naval doctrines, now with China as the primary adversary.
#### Why Focus on Air-to-Air Missiles in the Stealth Era?
Both the US and China are developing next-generation stealth fighters capable of evading enemy radars. While the US has advanced from the F-117 Nighthawk to the F-35, China is catching up with its Chengdu J-20. Despite these advancements, the focus on long-range air-to-air missiles stems from the need to counter threats from afar, such as China’s PL-15, which can be launched from stealth fighters like the J-20.
A stealthy Chinese aircraft could potentially detect and target non-stealthy US aircraft from long distances. This heightened risk has propelled the quick development of the AIM-174B, allowing US jets to strike from a safer distance. Experts note that while China is advancing in missile technology, the radar capabilities for such long ranges remain in question.
#### The Island Chains
A potential military confrontation between the US and China could occur near the South China Sea, a crucial maritime trade route. China has threatened Taiwan with military action, and the US, under the Taiwan Relations Act, is committed to defending Taiwan. The Island Chain Strategy, initially devised to counter Soviet and Chinese expansion, remains relevant today for curbing Chinese advances.
The First Island Chain, comprising territories like the Kuril Islands, Taiwan, and the north Philippines, serves as a critical defense boundary for the US. Any conflict in this area would position the US near China, where the AIM-174B missile would be crucial in maintaining a strategic advantage.
#### India and Its Air-to-Air Missile Arsenal
India has developed the Astra Mk1 beyond visual range air-to-air missile, operational on the Su-30MKI fighter jet with a speed of Mach 4.5 and a range of 100 km. Future versions, Astra Mk2 and Mk3, are in the trial phase. While these developments are significant, they lag behind the capabilities of the US and China. The primary long-range air-to-air missile in the Indian Air Force is the Meteor, deployed on Rafale jets, and considered one of the most advanced in the world.
The deployment of the AIM-174B by the US indicates a strategic pivot in the Indo-Pacific, heightening military readiness and altering the regional power equation.
