Jane's Defence Weekly and Center for Strategic and International Studies stated that it is the Iranian version of North Korea's Hwasong-10. North Korea sold a version of this missile to Iran under the designation BM-25. The number 25 represents the missile's range of 2,500 km. Iran said it has decreased the missile size over the initial version, reducing the propellant mass and range. Such a range covers targets in Israel, Egypt and Saudi Arabia, and NATO members Romania, Bulgaria and Greece, if fired from Western Iran. The IRGC Commander of the Aerospace Division, Brigadier General Amir Ali Hajizadeh, stated that the Iranian variant "has become smaller in size and more tactical", which may explain the missile's decreased range. A second theory asserts that Iranian officials do not want to raise concern in Europe about their missile program, and are purposely underestimating the range. The IISS's Michael Elleman said that Iran today likely can go beyond the original range of 1,000-2,000 kilometers with its Khorramshahr ballistic missile. However, it chose to limit its range by testing with a heavier warhead. Due to the heavy payload, it has the potential to carry nuclear warheads. It is uncertain whether it can carry multiple nuclear warheads due to its size. The gas output from these rockets, range, warheads, and rocket launchers are different. In the Khorramshahr missile, there is some small separated gas output from the big one in the center to control the missile without wings. The gas output model of the Khorramshahr missile is more like the Hwasong-12. Brigadier General Amir Ali Hajizadeh, the commander of Aerospace Force of the IRGC, said that Khorramshahr is a missile with a multiple-warhead capability. • Illustration — A Khorramshahr-4 ballistic missile The Khorramshahr-4 was unveiled on 25 May 2023. The new variant is reported to have a range of 2,000 km with a 1,500 kg warhead. It has a more advanced engine that uses hypergolic fuel, which can be stored in tanks for years, shortening the launch preparation time to 12 minutes. The new propellant requires smaller tanks, reducing the motor section to about 13 m, with the warhead adding about 4 m to the missile's length. It has an airframe made of a stronger composite material, and a mid-phase navigation system that enables it to correct its course when outside of the atmosphere, so it is not reliant on terminal guidance that can be disrupted by electronic warfare systems.

The Khorramshahr was first reportedly test-fired on 29 January 2017, flying about 950 km before exploding. It was tested again as of August 2020, with a small re-entry vehicle (RV) that extends its range and possibly its accuracy. Iran test-fired Khorramshahr missiles on February 5 and February 8 2026, just before the 2026 war, likely as a demonstration of capabilities against the US.
