Whats the problem?

2kN Cryogenic engine ... you can do that Sh!!!t with solid fuel kick motors ...

I think Iran has the most advanced space industry only after US/Russia/EU/China/Japan/India and maybe Israel.

OK ... back to topic ...

Fuel is kerosene with some additional hydrocarbon compounds added. Kerosene is a type of general-purpose fuel (such as in aircraft). The fuel tank is made of the magnesium alloy (AlMg6), which consists of 94% aluminum and 6% magnesium. The size of the fuel tank is 2/3 the size of the oxidizer tank.

Oxidizer is nitric acid HNO3 (RFNA, Red fuming nitric acid) , Oxidizer tanks are made from aluminum-magnesium alloy (AlMg6) to prevent corrosion by nitric acid and to reduce the weight.

The mechanism for stage separation is MDF (Mild Detonation Fuse)

The accelerating and braking motors change the speed of the two stages to ensure a safe distance between them after separation.

Two flight termination UHF antennas separated by 180 ˚ are used for precise control of the fuselage.

North Korea used imported commercial products for most of the electronic devices and sensors, including temperature detection devices (DC-to-DC converters, temperature sensors), electric devices, pressure sensors, etc. The acceleration motors and some electronics were made in North Korea.
