North Korea missile timeline: from monster missiles to hypersonic weapons

North Korea often tests new weapons to gain diplomatic leverage in times of crisis

North Korea conducted its 10th missile test of the year on Wednesday, launching an “unknown projectile” from an airfield near the capital Pyongyang, according to South Korea, who said the test failed.

Analysts said the missile might have been a Hwasong-17 intercontinental ballistic missile, known as the monster missile, which is feared to be capable of carrying more than one nuclear warhead, if effective.

The nuclear-armed regime of Kim Jong-un has conducted a series of tests in recent months, including hypersonic missiles that can fly at five times the speed of sound.

In the third hypersonic test this year, on January 13, Pyongyang tested a “boost glide” hypersonic vehicle, which apparently hit a target 1,000 kilometres away.

Analysts are sceptical about how effective these weapons – which are highly experimental – actually are. Some scientists claim the extreme heat from air friction caused by drag at such speeds could make the weapons highly unstable, possibly rendering targeting systems ineffective.

These problems are a challenge for China and the US, raising further doubts that Mr Kim's much smaller military has the funding or expertise to effectively use the weapons.

The tests are nonetheless widely condemned for raising tensions on the heavily militarised Korean Peninsula.

The US has accused North Korea of “seeking attention” with the testing, in the words of US Secretary of State Antony Blinken. Few believe tests are a lead-up to a new war with South Korea. The last ended in 1953, leaving decades of simmering tensions and fears that a new conflict could kill millions.

Tests continued during lulls in tension, such as the summits between Mr Kim and Donald Trump and after Joe Biden's inauguration, and low points – including a threat by Mr Trump to destroy North Korea in a “sea of fire”, and North Korean threats to fire a nuclear weapon at the US.

Below is a timeline of recent tests and tensions, excluding earlier leaps in North Korea's missile development in the 1990s.
