Taepodong-1 (Korean:대포동-1) was the external designation given to a three-stagetechnology demonstrator developed byNorth Korea, a development step toward anintermediate-range ballistic missile. The missile was derived originally from theScud rocket and was tested once in 1998 as a space launch vehicle. As a space launch vehicle, it was sometimes called thePaektusan 1.[1]
On August 31, 1998, North Korea announced that they had used this rocket to launch their first satelliteKwangmyŏngsŏng-1 from a pad on theMusudan-ri peninsula. However, the satellite failed to achieve orbit; outside observers conjecture that the additional third stage either failed to fire or malfunctioned.[2] This is contrary to official statements of the North Korean state media, which stated that the satellite achieved orbit about 5 minutes after launch.[3] On this single launch, the main two-stage booster flew for 1,646 km without any significant problems.[4]
The rocket was launched eastward, passing over Japan at an altitude of over 200 km. The second stage came down into thePacific Ocean about 60 km past Japan, and the third stage about 600 km beyond Japan.[5] According to post-launch analysis of the launch vehicle, debris from the third stage fell as far as 4,000 kilometers from the launch pad. Some analysts believe that a three-stage space booster variant of the Taepodong-1 could be capable of travelling as far as 5,900 kilometers with a very small payload.[6]
In 2003, the USDefense Intelligence Agency reported to the Congress: "We have no information to suggest Pyongyang intends to deploy the Taepo Dong 1 (TD-1) as asurface-to-surface missile in North Korea. We believe instead that the vehicle was a test bed for multi-stage missile technologies."[7] In 2009, the USNational Air and Space Intelligence Center assessed that the Taepodong-1 was a technology demonstrator, a development step toward longer-range missile development.[8]
TheTaepodong-2, orUnha-2, was the successor to the Taepodong-1 technology demonstrator, with a first (unsuccessful) test launch in 2006.[9]
The rocket's first stage is aHwasong-7 (Rodong-1)MRBM, and the second stage uses a single engine from the Hwasong-7.[1]
In a nominal space launch, the first stage burns for 95 seconds, before separating, and landing about 250 kilometres (160 mi) downrange. The payload fairing separates 144 seconds after launch. This is followed by the depletion and separation of the second stage, 266 seconds into the flight, resulting in an impact about 1,650 kilometres (1,030 mi) downrange. The third stage, which is spin-stabilised, then burns for 27 seconds to insert the payload intolow Earth orbit. The payload is estimated at 6 kg (13 lb) mass.[1]
