韩联社首尔4月16日电 据韩国联合参谋本部16日消息,朝鲜当天上午在咸镜南道新浦一带试射型号不详的导弹,但试射以失败告终。

经确认,朝鲜近来连续试射失败的导弹是将飞毛腿导弹改良过的新型导弹。该导弹为反舰弹道导弹(ASBM),可在韩半岛出现紧急状况时,瞄准美军兵力。4月17日(当地时间),美国《ABC新闻》报道称,美国防部将朝鲜新型导弹的编号定为KN-17,KN指朝鲜(North Korea)。美国情报当局认为KN-17是由飞毛腿导弹改良的反舰弹道导弹,安装有一级火箭液体燃料发动机。发射是通过移动型导弹发射台(TEL)进行的。据悉,反舰弹道导弹是用来打击航母等海上移动目标物的导弹。一般的弹道导弹是按照既定的轨道打击固定的目标,但是反舰弹道导弹具有可改变轨道进行攻击的能力,若目标物出现位置上的移动,该导弹将在最后阶段找到目标进行攻击。
朝鲜在美中首脑会晤前的4月5日、美国副总统迈克·彭斯(Mike Pence) 访韩的4月16日均在朝鲜咸镜南道新浦进行了导弹试射。4月5日的导弹飞出约60多公里,16日的导弹在发射4-5秒后爆炸。韩美军方当局一开始推测认为4月5日试射的导弹为舞水端-2型中程弹道导弹(IRBM),随后又改口称该导弹疑似为飞毛腿或飞毛腿-ER系列导弹。


Exclusive: North Korea Tested Its New Intermediate-Range Ballistic Missile 3 Times in April 2017

North Korea's three major failed ballistic missile tests in April 2017 involved the Hwasong-12 intermediate-range ballistic missile, a U.S. government source with knowledge of the matter told The Diplomat, speaking on the condition of anonymity.

Pyongyang conducted tests of the system on April 4 and 15, from near its naval base at Sinpo, and another test on April 28 from the Pukchang Airfield in South Pyongan province.

The first two tests out of Sinpo both failed, but the first produced limited flight to a range of 60 kilometers with an apogee of 189 kilometers. Both tests out of Sinpo had been previously reported to involve a new Scud-variant known as the KN-17 by the U.S. government. North Korea has introduced a new short-range Scud-variant, which was first tested on May 28.

According to the source, a missile known within the U.S. government as the KN-17 was indeed tested out of Sinpo, but is not, contrary to previous reports, a single-stage, liquid-fueled Scud-variant with terminal maneuverability. Instead, it's the same missile that North Korea successfully tested on May 14 from near Kusong: the Hwasong-12 IRBM.

The source added that North Korea's April 28 launch from the Pukchang airfield in South Pyongan province, previously reported as an unknown missile, also involved the Hwasong-12 IRBM. The IRBM in that test exploded shortly after launch.

The United States government uses the “KN” missile naming system to designate systems under development and in use by North Korea. For instance, the Pukkuksong-2, the solid-fuel medium-range ballistic missile shown first in February, was designated the KN-15 — the first new publicly reported KN designation in 2016.

North Korean systems receive new designations if they are substantively different from previously known systems.

The repeated testing of the Hwasong-12 IRBM in April is significant and serves to deprecate previous analysis that assumed the KN-17 was North Korea’s new Scud and possibly an anti-ship ballistic missile prototype. There are a few implications given this newly reported data.

First, if, as it appears, the Hwasong-12 is based on North Korea’s indigenously developed high-thrust liquid-fuel engine, first demonstrated in March, it may be the case that Pyongyang had trouble perfecting the system with its first attempted flight tests.

This counters previous impressions that Pyongyang’s test on May 14 was the first-known flight attempt for the Hwasong-12. Three failed tests prior to a success in May suggests that North Korea likely had to make changes to the system to achieve a successful test.

For instance, given that the April 4 test was reported to have “pinwheeled” in flight, North Korea may have encountered problems with flight stabilization for the new missile. The Hwasong-12 uses a skirt paired with vernier engines instead of grid fins, which Pyongyang has used on its Pukkuksong-1 submarine-launched ballistic missile (KN-11). The missile could also have encountered an engine failure in flight or improper flight stage separation.

Second, observers, including at The Diplomat, had speculated that the April 4 and April 14 tests could have served a signaling purpose given reports at the time of the USS Carl Vinson strike group's deployment to the Korean peninsula. Had the Hwasong-12 test attempts out of Sinpo succeeded, North Korea would have demonstrated a capability to strike U.S. forces at Guam.

Third, given that the Hwasong-12 was tested throughout April and in mid-May, North Korea's May 28 test of the new “ultra-precision” Scud with terminal maneuverability was the first — not potentially the third — attempted flight test of the system, suggesting that Pyongyang’s considerable experience with single-stage, liquid-fuel missiles has held up. North Korea’s exploration of terminal maneuverability, thus, suggests an iterative improvement to its existing Scud programs.
