Let me quote from same source which you are using:
The Simorgh uses engines developed for the Shahab-3 medium-range ballistic missile (See annotation 1 in the Sketchfab model). The Shahab-3 is Iran’s version of North Korea’s Nodong missile, which Iran improved with assistance from Russian and Chinese entities.
Specifically, the first stage of the Simorgh uses a cluster of four Shahab-3 engines. This approach is very similar to North Korea’s Unha launch vehicles, whose first stages have used a cluster of four Nodong engines (Annotation 2).
Desperate hasbara troll, I have said from the beginning that they use the same engine. You're basically replying to me with what I have been saying right from the start
As I said, even Americans use the same engines as some Russian SLV's, by your logic, American SLVS are copies of Russian SLV's
It seems this hasbara troll can't read, you just quoted them as they said the Simorgh and Unha are
similar. whilst you were claiming the simorgh is a copies of unha first 2 stages
You just quoted a source that completely contradicts what you've been saying . What an epic fail.
Many SLV's are similar, it does not mean anything. In this case, it just means Iran has helped north korean and that is why you can see Iranian influence in their systems.
"North Korea’s Unha-series may now incorporate some Iranian technologies. North Korea’s Unha-2 launch in 2009 failed when the rocket’s third stage did not separate properly. North Korea’s first successful Unha-series launch, in December 2012, used a larger third stage that appeared to be similar to a rocket stage previously seen only in Iran. "
This is from the very source you're quoting. It seems this hasbara can't even read.
So all your space program is solely based on North Korea.
As for fuel tank size and ratios which u are posting - thats just minor modification, just like Scud-B and Scud-C:
You're posting from my source but making claims that have nothing o do with they've said. I can also post that source and say shavit is basically French technology.
To remind you:
Scuds are actually part of the same family officially whereas you, a troll on a forum are trying to claim Unha and simorgh are based on each other. All your claims have been debunked so far.
Only thing simorgh and unha share is their engine, and even they are configurated differently:
They even use different propellant:
the ratio of the fuel and oxidizer tanks is different, suggesting a different combination of propellants.
So they are different size, Iranian simorgh has a much bigger first stage, Unha uses Iranian third stage design, they use different propellant. They're completely different system and only thing they share is an engine which I have said the beginning.
