North Korea Tests New Missile

Article excerpt

North Korea successfully tested a new medium-range ballistic missile last month that demonstrated several technical advances, including a domestically produced launch vehicle.

The missile, known as the Pukguksong-2, is a two-stage, solidfueled system, likely adapted from the submarine-launched ballistic missile, the Pukguksong-1, that North Korea has been developing for the past several years. North Korea is prohibited from testing ballistic missiles by UN Security Council resolutions, but has continued to develop and test a range of ballistic missiles. The UN Security Council condemned this latest test on Feb. 13.

The Korean Central News Agency (KCNA), in a Feb. 13 report, described the missile as a "Korean style new type strategic weapon system" and called the test a success. The report said that leader Kim Jong Un had the system developed based on the indigenously developed Pukguksong-1, which international weapons analysts call the KN-11.

The missile flew approximately 500 kilometers, but was tested at a lofted trajectory that the KCNA said was done to take into account the security of neighboring countries. Experts assess that the missile, if flown a standard trajectory, would have a range of approximately 1,200 kilometers, which is similar to the assessed range of the submarine variant and puts it in the category of a mediumrange ballistic missile. When deployed, the Pukguksong-2 will likely be nuclear capable.

North Korea has other land-based, medium-range ballistic missiles, but they are liquid fueled. Solid-fueled ballistic missiles require less support because they are not fueled at the launch site, making them more difficult to track and pre-empt.

North Korea also used a technique for launching the missile that is similar to a submarine launch. The Pukguksong-2 was ejected from the canister using compressed gas. The rocket engine ignited after the launch, which protects the vehicle from the worst of the heat from the launch.

North Korean Launch Vehicle

North Korean media highlighted that the tracked vehicle used to transport and launch the missile, often referenced as a transport-erector launcher (TEL), was also indigenously produced. Joshua Pollack, senior research associate with the James Martin Center for Nonproliferation Studies, told Arms Control Today on Feb. 17 that North Korea's claims that the TEL was produced domestically are credible.

Pollack said there are aspects of the vehicle that resemble Soviet-made TELs, but the newly displayed model appears to be unique. …
