Unha-2 (Kwangmyŏngsŏng 2) [KRT]
The Unha rocket, which bears the western codename Taepodong-2, is North Koreas second attempt to produce a long range missile. It is thought to be capable to reach the western areas of the United States or to place a small satellite into orbit.
The Unha is a three stage launch vehicle. The rocket uses storable liquid fuel. The first stage is a new design, which features four Nodong class engines with four steering engines and is 2.40 m in diameter. It uses kerosene and nitric acid as propellants. The second stage with a 1.5 m diameter features a Scud-class engine and uses also kerosene and nitric acid. The 1.2 m diameter third stage could be related to the second stage of the Iranian Safir rocket and uses UDMH and NTO as fuels.
A second launch attempt of an Unha family rocket featuring the three stage rocket Unha-2 was conducted in April 2009, but failed to orbit its payload.
An improved version was built under the designation Unha-3.
