Last week, pictures and videos emerged of a missile being tested in North Korea which appeared to be equipped with a “hypersonic glide vehicle” (HGV). In the past decade or so, North Korean missile tests have become so frequent that they have come to be regarded as a sort of background noise in global affairs. But the fact that the country now appears to possess HGVs should raise alarm bells in the West.

The first thing to note about North Korea’s HGV is that it is unlikely to have been developed there. The technology is simply too advanced to have been produced by the hermit kingdom, and it seems more probable that either Russia or China handed it to Pyongyang. The second thing to note is that the United States and its allies do not currently possess this technology, meaning that North Korea has an advantage over the West in this sphere. This detail shouldn’t be skirted over.

North Korea has had access to missiles which can reach the US mainland for around a decade. Yet until now it was assumed that, in a worst-case scenario, American air defence might be able to shoot down any intercontinental ballistic missiles (ICBMs) launched by the North Koreans. Now, with HGVs in reserve, previous bets are off.

HGVs operate by being launched into orbit on the back of a conventional ballistic missile, but then break away from their launch vehicles and re-enter the earth’s atmosphere. At this point, they reach hypersonic speeds — anything higher than five times the speed of sound, though some HGVs are apparently capable of achieving 27 times the speed of sound.

What’s more, HGVs do not follow a standard parabolic trajectory. Rather, as they re-enter earth’s atmosphere they zig-zag chaotically toward their target. With HGVs travelling at such extremely high speeds and following an unpredictable trajectory, they become harder to shoot down.

This changes the geostrategic picture in the Asia-Pacific theatre. If tensions ever escalated between North Korea and the US, the latter would have to consider that the former could, in theory at least, threaten the American mainland. This will also come as a severe concern to the South Koreans, who are well aware that the North would still like to conquer the country and integrate it into the communist state.

This development raises questions about a potential showdown between China and America in the region. We have seen in the Middle East how Iran can deploy proxy armies such as the Houthis in Yemen to attack Western ships while maintaining plausible deniability that they are behind the attack. What if the Chinese or the Russians encouraged North Korea to fire anti-shipping missiles at American naval vessels in the region? If the Americans tried to counterattack on the North Korean mainland, they would risk Pyongyang firing a nuclear-tipped HGV at the US mainland.

When the Chinese tested a HGV a few years ago the reaction was one of shock, with some Western analysts calling it a “Sputnik moment” for the country. In the wake of the North Korean test last week, it feels that many are having a hard time processing it. A common reaction was to simply deny that the HGV was real and actually flew — but US Navy reports from a couple of days later appear to confirm that the test was indeed real.

The world order is changing rapidly. As they find themselves focused on the crisis in the Middle East and the potential collapse of the front line in Ukraine, suddenly Pyongyang comes out of nowhere and tests an extremely advanced and threatening weapons system. What is needed today is a complete rethink of Western foreign policy to deal with the new world that is now emerging. Business as usual is looking increasingly untenable.
