Translation: "Taepodong 2 drops off the coast of North Korea, 400 kilometers --> dozens of kilometers, complete failure"

Dr. J over at the ArmsControlWonk asked me to run down the Mainichi Shimbun article referenced in the first paragraph of AFP story from July 30, 2006. By the power of Greyskull and the wonder of Dow Jones's Factiva, I managed to track it down and the following rough translation (the original Japanese text has been attached to the comments section):

"Taepodong 2 drops off the coast of North Korea, 400 kilometers --> dozens of kilometers, complete failure"

* No Dong 2 and Scud 4 also tested -- Japanese Defense Agency report.

July 30, 2006

By Akitaka Furuhon

The Japanese Defense Agency (JDA) released an outline of a reconnaissance report concerning high-profile ballistic missile tests conducted in the vicinity of North Korea on July 29. Of the seven missiles tested, it concludes that the third missile, which has specifically classified as the two-stage Taepodong 2, was a complete failure. The 400 kilometer flight path estimated was revised to read "Only a few dozen miles off of the coast in North Korean waters." Of the remaining six missiles, report concluded that two were "No Dongs" and four where "Scuds."

The July report was the result of the JDA reconciling early information like missile trajectories seen by the Marine Self-Defense Forces' Aegis cruiser radars with later data from the U.S. military's ground-based radar.

The Taepodong 2 missile was launched from Musudanri in northeastern North Korean. Its first stage is newly designed booster and its second stage is a Nodong missile. At first, the missile appeared to have dropped into the ocean 350 kilometers north-north west of the coast of Niigata prefecture, which would have been a distance of 400 kilometers. The result of several data analyses, however, revised this distance based on the conclusion that the first stage burned out after 40 seconds and the second stage did not separate. The observed burn time of less than three minutes under normal operating conditions leads to the conclusion that test was a complete failure.

On the one hand, the report said "the probability that the missile's target was the Pacific Ocean is high," but it avoided specifics because the launch was far from normal.

The remaining six missiles were launched towards the northeast from Kittaeryong in southeastern North Korea and they were seen falling into the ocean about 400 miles away. The missile trajectories were not tracked long enough for accurate analysis, but the report ends it analysis by stating "the six launched missiles fell within dozens of kilometers of their range" without providing the actual impact sites.

Using the six missile's initial velocity and burn pattern, two were classified as No Dongs and the four others were classified as Scuds. Based on the trajectory analysis, the report judges that a new IRBM (Editor's Note: the Japanese author translates the acronym IRBM to 'submarine-launched medium range missile' -- like the Norks have subs large enough) currently in development was not included in the tests. The report does offer some minor specifics on the Scuds and ends with the observation that "it is possible that a new Scud design was included among the missiles tested."

(Editors's note: I am not very confident about my take on this next sentence) In regards to the launch procedures used by North Korea, Japanese and American intelligence agencies are waiting to see whether the tests are proclaimed a demonstration of North Korean power. The report also does not draw conclusions on North Korea's intent.

(Update: MTC was kind enough to translate the last paragraph correctly. By misinterpreting the meaning of "打ち上げ順序," I screwed the whole paragraph up -- my bad.)

As for the order of the missile firings, the intelligence agencies of both the U.S. and Japan have said, "It is really not in our best interest to reveal our capabilities." They defer on making a public statement. They will also not be confirming in a published report the mappings out of any of the missile firings.

Interesting stuff. Let me know what you think -- I'm going to weigh in on it sometime tomorrow.

My translation is rough, but fairly accurate. Here is the original text pulled from Factiva's archives:

テポドン2は北朝鮮近海に落下 400キロ→数十キロ、完全な失敗

 ◇ノドンが2発、スカッド4発--防衛庁調査報告

 防衛庁が近く公表する北朝鮮の弾道ミサイル発射に関する調査報告書の概要が29日、明らかになった。発射された7発のうち、種別を特定していた3発目の2段式「テポドン2号」については「発射は完全な失敗」と断定。約400キロと推定していた飛距離は「落下は沿岸から数十キロの北朝鮮近海」と修正した。残りの6発については2発が「ノドン」、4発が「スカッド」と結論づけた。防衛庁は週内にも公表する。【古本陽荘】

 報告書は、海上自衛隊のイージス艦がとらえたミサイルの航跡など初期情報に、米軍の地上レーダーなどの追加情報を合わせて解析した結果を防衛庁独自にまとめた。

 北朝鮮北東部の舞水端里(ムスダンリ)から発射されたテポドン2号は、1段目が新型ブースターで、2段目がノドン。当初は新潟県沖北北西約350キロ付近の海域まで約400キロ飛んだとみられていた。しかし、複数データの解析の結果、報告書は「1段目の燃焼は約40秒で終わり、2段目は分離しなかった」と断定し飛距離も修正した。正常に稼働した場合、燃焼時間は3分以上と見られており、完全な失敗と結論づけた。

 一方、目標については「太平洋側に向けた可能性が高い」と見ているが、正常な打ち上げではないことから特定は避けた。

 残り6発はいずれも北朝鮮南東部の旗対嶺(キッテリョン)から北東方向に発射され、400キロ前後の海域に落下したと見ている。しかし、正確な解析に足る十分な航跡が得られていないミサイルもあり、落下地点は特定を避けたうえで「6発とも(直径)数十キロの範囲内に落下した」との分析にとどめる。

 6発の種別は、初速や燃焼パターンからノドン2発、スカッド4発と特定。航跡などの解析の結果、開発中とされる新型IRBM(潜水艦発射中距離ミサイルの改良型)は含まれていないと判断した。スカッドは細かい種別の特定には至っておらず、「新型スカッドが含まれていた可能性がある」との表現にとどまる見通しだ。

 打ち上げ順序については、日米情報当局は「手の内を明かすのは得策ではない」としており、公表を見送る。発射意図も報告書では断定しない。

Robot Economist -

The last paragraph says:

As for the order of the missile firings, the intelligence agencies of both the U.S. and Japan have said, "It is really not in our best interest to reveal our capabilities." They defer on making a public statement. They will also not be confirming in a published report the mappings out of any of the missile firings.

MTC - Oh, I get it, "打ち上げ順序" is that kind of 'order.' That makes a hell of a lot more sense now.

Thanks for the input!
