Iranian transfer of it advanced solid propellant technology to North Korea is a serious concern along with what it has already received from Russia that does not stand up when considering the understood state of North Korea's solid propellant ballistic missile program even if they are benefiting from Iran's extensive efforts in that area of ballistic missile technology development.
The advanced nature of the system comes from the fact that the warning time for these missiles has been greatly reduced to mere minutes from that available through the existing liquid propellant Shahab-3 series of hours in preparation. This constitutes a major strategic threat to the regions with its range performance capability. This says nothing of the known to be deployed liquid propellant 4,000 kilometer range No-dong-B never displayed or paraded by Iran . No-dong-B is deployed both in Iran and North Korea .
Finally on January 29, 2007 the US government acknowledged for the first time the existence of several new Iranian and North Korean missiles under development through a speech by the deputy director of the Missile Defense Agency of the Pentagon Army Brig. General Patrick O’Reilly before the George C. Marshall Institute. In that speech he described the Iranian multi stage Ghadr-101 with a 750-800-1000 km range and the two-three stage Ghadr-110 (Ashura) solid propellant missile with a range of (1,324 miles) 1,995.16 or close to 2,000 kilometers. It has been known that the Iranians are working on the Ghadr-101 as well as the Ghadr-110 (Ashura) solid propellant missiles.
The Ghadr-101, 110 solid motor development was completed in 2005. He also described the two stage Taep’o-dong-2C/3 as having a range of (6,200 Miles) 9,975.8 kilometers and the three stage version with a range of (9,300 miles) 14,963.7 kilometers with a 200-250 kg warhead. He went further in his slides
presentation to show that the liquid propellant No-dong-B/Mirim has a demonstrated range of 2,000 miles or 3,218 kilometers (3,000 kilometers) when it is capable of flying (2,485 miles) or 4,000 kilometers. (24) The Nodong-B was described as “a qualitative improvement in the performance” from earlier North Korean missile systems. The Iranian Ghadr-101, 110, 110A will in fact also provides Iran with an ASAT capability besides its operational MRBM and IRBM capability.
