Taepodong-2
Taepodong -2 (Korean 대포동 2 호, named after the former name of the missile base Musudan -ri ) is the code - name of a North Korean intercontinental ballistic missile, which is based on the technology of the North Korean Taepodong -1 also. Chance it is also known as No- dong -3, Hwasong (Mars) -2 or Moksong (Jupiter ) denotes -2.
In the version as a satellite launcher, they will of North Korea as Unha - 2 denotes ( 은하 _2 호 Korean for "Galaxy " ), a modified version exists as Unha - third
A number of different configurations has been suggested by analysts over the years, but the data obtained by satellite reconnaissance in advance of the first launches seem to confirm that the configuration of TD -2C largely corresponds to the actual missile.

Speculation, based on the configuration TD -2C
- Range: 4700-6000 km with 700 to 1000 kg payload
- Take off weight: 79.2 t
- Diameter: 2.20 m

Description of Unha 2 and 3
The Unha 2 and 3 each have three stages. The first stages each have four engines. The engines burn at the Unha 2 fuel UDMH with the oxidizer AK -27 ( nitric acid ) and the same in the Unha 3 fuel with the oxidizer nitrogen tetroxide. They are otherwise identical in both missiles and have approximately 16.7 meters in length, about 2.4 meters in diameter. The second stages each have two engines that burn the same fuel as the respective first stage, and are very similar, with about 8 meters in length at the Unha 2 and about 8.1 meters in length when Unha 3 The diameter of both stages 1.5 meters. However, the amount of fuel and the weight to be significantly lower in the Unha 3. The Unha 2 used in the third stage, a solid rocket engine, while the Unha 3 uses a powered liquid propellant stage with two engines. The third stage of Unha 3 uses the combination fuel propulsion system, like the first two stages. The third stage of Unha 3 is about 3.8 meters longer, heavier and more powerful than the third stage of Unha 2, which is only about 3 feet long. The diameter is about 1.25 meters for both devices.
Use
According to U.S. and Japanese government information North Korea has carried out the first test launch of a Taepodong -2 in the early morning of July 5, 2006. According to the U.S. government this flight is, however, failed and the rocket crashed after about 40 seconds into the Sea of Japan, between the Asian mainland and Japan. It is unclear whether this was a test flight in the configuration as ICBM or whether a satellite should be placed into Earth orbit.
After North Korea's information ( " Bright Star " 광명 성 2 호 Korean) was on 5 April 2009 by a Unha -2 successfully the satellite Kwangmyŏngsŏng -2 transported into space, which sends measurement data and revolutionary songs at a frequency of 470 MHz to Earth. The U.S. and South Korea deny this and claim that the rocket had fallen into the Pacific. The launch took place contrary to the provisions of Resolution 1718 of the UN Security Council, which North Korea prohibits the use of long-range ballistic missiles. It is assumed that a test of military technology should be veiled.
An attempt to start a Unha -3 took place from the new launch site Sohae on April 12, 2012. The launch preparations were made with unusual openness for North Korea, even foreign journalists access has been granted to the launch site. The launch took place in a southerly direction to bring the weather satellites Kwangmyŏngsŏng -3 into an orbit with a high inclination ( Circular 500 km altitude with 97 ° inclination to the equator ). Broke Approximately two minutes after the start or exploded the rocket about 70 km altitude. The debris reached a peak altitude of about 151 km and fell into the sea between the People's Republic of China and South Korea. North Korean officials confirmed the false start and had it reiterated that the mission had pursued a purely scientific purpose. Internationally, however, called the start out strong criticism, including condemned unanimously by the United Nations Security Council the rocket launch as a " serious breach" of UN resolutions.
The second launch of Unha -3 on 12 December 2012 has been successful, however. After a short time before the launch window was extended due to alleged technical problems still, launched a Unha -3 and brought a satellite into orbit, which was heavily criticized internationally. The back Kwangmyŏngsŏng -3 satellite was called exposed after almost nine and a half minutes in space. Its orbit is 499.7 x 584.18 kilometers high and has an inclination of 97.4 ° relative to the equator. South Korean experts have analyzed in December 2012 from salvaged wreckage of the successful Unha -3 and were using computer simulations to view the rocket could cover with a payload of about 600 kg up to 10,000 kilometers. This is the first subject and the United States in the range of North Korean weapons systems.
However, according to new studies, the Unha -3 appears to have been specifically optimized for use as a launcher.
Costs
According to press reports, which are based on the South Korean estimates, the cost of the two missile launches in 2012 were approximately U.S. $ 1.3 billion. These costs are broken down as follows: U.S. $ 600 million will be only the start-up costs, added $ 400 million for the launch complex ( launchers, infrastructure, etc. ) and U.S. $ 300 million for the additional necessary equipment.
