Most sources refers them as 122mm tho.

Other angle

Most sources are referring to it as the ‘M1981’ 122mm SPG, but that’s wrong.

  1. It has no muzzle brake. That doesn’t make sense for a 122mm howitzer, nor has that configuration ever been seen

  2. The cannon can be identified by looking at its base, just before the gunshield

But Korean sources are not talking about M1981, apparently few korean source says they are ‘M1975’(don’t know that name is right) with modified 122mm D-74/Type 60 without the Muzzle brake(and even different barrel?)? Every single korean site, from small community to major brodcasting system, says 122mm. I’m confused.

This thing, I think.

They’re wrong, it doesn’t matter that it’s what everyone is saying. It’s a relatively easy mistake to make, but you have to remember the majority of people commenting on it are not well-versed in military vehicles or cannons, and the few that are, are not well-versed in obscure North Korean SPG designs.

‘M1975’, for example, refers to the 130mm-armed ATS-59. The ‘M####’ designations are confusing and often contradictory, you shouldn’t rely on them, people get them mixed up all the time.

There are also a number of AI-generated images of NK SPGs at the border going around now, as well as AI-generated slop news accounts talking about how North Korea has SPGs with 60km+ ranges ready to fire at the border (obviously incorrectly referring to the Chuch’ep’o (Koksan)). A lot of the reporting on this is sensationalist nonsense.

These are the indigenous 100mm field guns (likely based on the Romanian A407), as seen on the ATS-59 / ‘Tokchon’.

Terrible quality but you can see they are identical cannons.

Umm, apparently even at National assembly, in front of Minister of National Defense, they are talking them as 122mm. I’m even more confused.

Governments can also get things wrong.

All I can say is, we know what the 100mm cannon looks like, we know what the 122mm D-74-based cannon looks like, and we know what the ATS-59-based SPGs for both those cannons look like. And the vehicles in the images, based on the details of the cannon, are almost certainly the 100mm SPGs. Unless North Korea has for some reason developed a new 122mm cannon identical to the 100mm cannon, and also somehow discovered that removing the muzzle brake has no impact on recoil, then it’s the 100mm.
