The Taepodong-2 (TD-2, also spelled as Taep'o-dong 2)[3] (Korean: 대포동 2호) is a designation used to indicate a North Korean two or three-stage ballistic missile[4] design that is the successor to the Taepodong-1 technology demonstrator. The missile has been tested once, and failed 35–40 seconds after launch. In 2012 the U.S. Department of Defense assessed that the Taepodong-2 had not yet been deployed.[5] The Taepodong-2 is the technology base for the Unha space launch vehicle.

Details[edit]

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.[3] 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).[6] At maximum range, the Taepodong-2 is estimated to have a payload capacity of less than 500 kg (~1,100 lbs).[3]

According to Kim il Son, a former worker in the publications department of one of North Korea's top research centres, North Korea began development of the missile in 1987.[7]

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.[8] 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).[3] 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.[5]

Structure[edit]

First stage[edit]

Taepodong-2's first stage consists of four Rodong motors. It is unknown if the first stage has four separate tanks for fuel and four tanks for oxidizer,[9] or if it has two big tanks for fuel and oxidizer like the Unha rocket.

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.[6]

Launches[edit]

The first test launch of Taepodong-2 was conducted on July 5, 2006. Between 2006 and 2013 the Taepodong-2 was tested four other times, with its only successful flight coming in December 2012, when it was used as a space-launch vehicle.[10]

Missile test in 2006[edit]

A Taepodong-2 missile was test fired on July 5, 2006 from the Musudan-ri Missile Test Facility. According to preliminary reports, the missile failed in mid-flight 35–40 seconds after launch.[11]
