The Taepodong-2 (TD-2, also spelled as Taep'o-dong 2)[4] (Korean: 대포동 2호) is a designation used to indicate a North Korean two or three-stage ballistic missile[5] design that is the successor to the Taepodong-1 technology demonstrator. In 2012 the U.S. Department of Defense assessed that the Taepodong-2 had not been deployed as a missile.[6] The Taepodong-2 is the technology base for the Unha space launch vehicle, and was likely not intended as ICBM technology.[7][8]


As there is no publicly available imagery of the only Taepodong-2 launch, all estimates of technical parameters are approximate.[8]

Based on the size of the missile, the fuel composition, and the likely fuel capacity, it is estimated that a two-stage variant would have a range of around 4,000 km (2,500 statute miles) and a three-stage variant would be capable of reaching as far as 4,500 km (2,800 statute miles), giving it potentially the longest range in the North Korean missile arsenal.[4] The burn time of each stage is a little over 100 seconds, thus allowing the missile to burn for 5 or 6 minutes. Speculative variants of the missile could be capable of a range of approximately 9,000 km (5,600 statute miles).[9] At maximum range, the Taepodong-2 is estimated to have a payload capacity of less than 500 kg (~1,100 lbs).[4]

According to a former worker in the publications department of one of North Korea's top research centres, who defected to South Korea, North Korea began development of the missile in 1987.[10]

Very few details concerning the technical specifications of the rocket are public information; even the name "Taepodong-2" is a designation applied by agencies outside North Korea to what is presumed to be a successor to the Taepodong-1. The TD-2 first stage likely uses a liquid propellant (TM-185 fuel and AK-27I oxidizer) driven engine and the second stage likely utilises the Rodong short-range missile.[11] Depending on the range, the estimated payload capacity could be as high as 700–1,000 kg (~1,550 - 2,200 lbs) at short range, making it potentially suitable for conventional weapons payloads, NBC payloads as well as Earth orbit satellite delivery. At maximum range, the Taepodong-2 is estimated to have a payload capacity of less than 500 kg (~1,100 lbs).[4] North Korea has yet to demonstrate the ability to produce a re-entry vehicle, without which North Korea cannot deliver a weapon from an ICBM.[6]

In 2015, aerospace engineer and North Korea missile program analyst John Schilling stated that North Korea did not seem to be planning to create an operational ICBM from the Taepodong-2 technology, and that the Taepodong-2 had been mistakenly identified as an ICBM development, whereas in reality it was a space launch development vehicle.[7]


First stage[edit]

Taepodong-2's first stage consists of four Rodong motors.

Second and third stages[edit]

Little is known about the Taepodong-2 design beyond the first stage. Most likely the second stage is one of the Scud-derived North Korean ballistic missiles (either Rodong-1 or Hwasong-6), and the third stage most likely uses Chinese solid-fuel engines.[9]


2006 test[edit]

A Taepodong-2 was test fired on 5 July 2006 from the Tonghae test facility. According to reports, the missile failed in mid-flight about 40 seconds after launch.[12]

Subsequent Unha launches[edit]

Subsequent launches were intended to launch satellites, using a Taepodong-2 development called the Unha rocket. After two failures in April 2009 and April 2012, its first successful flight, Unha-3, occurred in December 2012 with the launch of the second version of Kwangmyŏngsŏng-3 satellite.[13]

This successful flight was repeated on 7 February 2016 (UTC) with the successful launch of Kwangmyŏngsŏng-4 using a similar rocket as Unha-3 even though the rocket is officially named as Kwangmyŏngsŏng (not to be confused with the satellite with the same name).
