Reports credit North Korea’s newest missile of terror with 2.5-ton warhead and 900-km range. Expert explains why those numbers can’t both be true

Russia may soon get 150 more missiles from North Korea, and their inaccuracy is precisely what makes them dangerous to civilians. This characteristic makes them above all weapons of terror, military expert and Defense Express director Serhii Zghurets said on Espreso.

The particular danger may carry the KN-30, credited with a range of up to 900 kilometers and a 2.5-ton warhead. For comparison, the warhead in Russia's Kalibr cruise missile is 450 kilograms, as in the Iskander ballistic missile, and even those destroy large objects. A missile carrying anything near five times that payload would hit far harder than any weapon already devastating Ukrainian cities.

The claimed specs don't add up

Zghurets urged skepticism toward the most hyped missile. The KN-30's credited figures can hardly be combined in one missile, he said. Physics forces a trade-off.

"If we are talking about a missile that can fly 900 km, then it has a significantly smaller warhead weight. If we are talking about 2.5 tons, then the range will be much shorter," Zghurets explained.

Either version remains dangerous, but the claims as advertised describe a missile that likely does not exist.

A 150-missile delivery is under discussion

North Korea keeps feeding Russia's arsenal. Pyongyang continues to strengthen Russia's military potential with missiles of several types, including the KN-23, KN-24, and KN-30, and a possible supply of about 150 North Korean missiles to Russia is now actively discussed, Zghurets said.

Even if the missiles' real characteristics differ from the claims, such a number would be a substantial addition to the Russian arsenal, he noted, more missiles for the campaign Russia fires at Ukrainian cities regardless of how well each one performs.

Inaccuracy makes them terror weapons

The missiles' precision is their defining flaw. By one estimate, Zghurets cited, missiles flying about 800 kilometers can deviate from their target by 18 kilometers, an error radius wider than most cities.

That rules out military precision but not harm.

"There is definitely no talking about any accuracy with these missiles. But as a weapon of terror that supplements the Russian arsenal, the Russians will of course need it now," Zghurets said.

A missile that can land anywhere within 18 kilometers of its aim point cannot reliably hit a military target, but if fired at a city, it will hit something, which is how Russia has used North Korean missiles against Ukrainian civilians.

Both sides get what they want from the axis

Moscow's interest goes beyond missiles. Russia is also interested in bringing in North Korean troops, which would free part of its own forces for combat against Ukraine, Zghurets said.

Pyongyang is paid in money and technology. North Korea seeks military-technological advantages from the cooperation, including improving its submarine-launched ballistic missile technology, and over the years of the war, may have received about $20 billion from Russia, Zghurets estimated.

The Moscow-Pyongyang military alliance is a serious challenge for the West, he said, though it is hard to predict how actively the US will try to limit the two countries' cooperation.
