The Taepodong-2 (TD-2, also spelled as Taep'o-dong 2)〔(North Korea’s Taepodong and Unha Missiles ), Federation of American Scientists, May 30, 2008〕 ((朝鮮語:대포동 2호)) is a designation used to indicate a North Korean two or three-stage ballistic missile 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 been deployed as a missile. The Taepodong-2 is the technology base for the Unha space launch vehicle, and was likely not intended as ICBM technology. ==Details== 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.〔 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).〔 At maximum range, the Taepodong-2 is estimated to have a payload capacity of less than 500 kg (~1,100 lbs).〔 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.〔(Taep'o-dong 2 (TD-2) - North Korea )〕 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.〔(NTI: Country Overviews: North Korea: )〕 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).〔 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.〔 In 2015 aerospace engineer and North Korea missile program analyst, John Schilling, stated creating an operational ICBM out of the Taepodong-2 technology did not appear to be in North Korean plans, and it had been mistaken as an ICBM development wheras it was a space launch vehicle development vehicle.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Taepodong-2」の詳細全文を読む スポンサード リンク
