God daaaaamn, breaking news: Iran has succeeded in testing ICBM solid fuel engine
Around mid-March, a large burn scar appeared in the rocket motor test stand area. This was the first time Iranian engineers had made use of this test stand, the largest of the four in the area, indicating that
they have reached a milestone in terms of the size of the motors.

Recently captured satellite imagery shows Iran’s efforts to produce bigger and better rockets that, because of their dual-use nature, could bring the Islamic Revolutionary Guard Corps closer to having intercontinental ballistic missiles.

1) according to Fabian Hintz, Test Stand 4 has a thrust between 164-246 tons
2) according to Uzi Rubin's article
"Iran’s winged horse rocket: Another step towards global reach", Sarir is a "
a giant three-stage solid-propellant SLV with an estimated take-off weight of almost 160 tons"
3) So we can assume that engine from Test Stand 4 is an engine for Sarir, which is a giant solid fuel SLV
Characteristics of Sarir:
Height: 35m
Diameter: 2,4m
Weight: ~160 tons (based on Uzi Rubin's article)
Thrust: ~190 tons
Payload to LEO: 1800kg
Compare it with US's solid fuel SLV
Athena II:
Athena-2

Height: 28,2m
Diameter: 2,36m
Weight: 120 tons
Thrust: 145 tons
Payload to 185km orbit: 2065kg
So as you can see Sarir is more or less comparable to Athena II (
the same 2,4m diameter solid fuel engines)
Athena II on the other hand is a modification of
US Peacekeeper heavy ICBM which can deliver 3,8 tons to 10.000km distance
4) So it is possible that Iran works on two types of solid fuel ICBMs:
1st type----light ICBM which can deliver 1 ton payload to 12.000km (Zuljanah-2)
2nd type----heavy silo based ICBM (
in a class of Peacekeeper) which can deliver 4-5 tons to 12.000km (Qaem=Sarir)
Even on this picture, Sarir looks like a modified heavy ICBM
