South Korea rejects North Korean doubts over hypersonic missile test
South Korea tested a hypersonic glide vehicle on Oct.
8 as part of its weapons development.
North Korean missile chief Jang Chang Ha questioned whether it reached hypersonic flight, pointing to images that showed no soot.
South Korea’s Defence Ministry said heat-resistant materials kept the vehicle clean during the test.
Hypersonic weapons usually travel at more than five times the speed of sound and can manoeuvre to evade defences.
The test examined thermal protection, guidance and control, and low-altitude manoeuvrability.
South Korea plans to keep developing the technology as it moves toward making the vehicle a weapon.
The test took place amid heightened tensions between the two Koreas and a regional push to develop weapons that can evade missile defences.
North Korea’s missile chief questioned whether South Korea’s hypersonic glide vehicle test achieved hypersonic flight, citing the vehicle’s clean appearance in released photographs.
South Korea’s Defence Ministry rejected the claim, saying the vehicle used heat-resistant materials and advanced thermal-protection technology.
South Korea test-fired the vehicle on Oct. 8, 2026.
The test assessed thermal protection, guidance and control systems, and the vehicle’s ability to manoeuvre irregularly at low altitudes.
South Korea said it plans to further develop the technology as it works to weaponise the vehicle.

What people are saying
It is hard to believe that it underwent hypersonic flight circumstances characterised by extremely high temperatures as its outside appearance is so clean with its coating paint remaining intact, not stained with any soot
Going forward, our military plans to further advance the related technologies as it moves to weaponise the HGV, a key strategic asset for future security
