2017年7月4日上午9时40分许,朝鲜在平安北道芳岘一带朝半岛东部海域发射了1枚弹道导弹。韩美军方认为,朝鲜此次发射取得成功。虽然导弹只飞行了933千米,但是据日本媒体报道,导弹的飞行时间竟然长达近40分钟,明显比5月14日成功发射的“火星”12中远程弹道导弹的飞行时间更长,这意味着新导弹的弹道高度更高、射程更远。美国专家称该导弹的最大高度可达2?800千米,采用正常弹道时,最大射程可达6?700千米。
At 4:40 am on July 4, 2017, North Korea launched a ballistic missile on the eastern coast of the peninsula in the vicinity of Fang Hyeon-nam Road, North Pyongan Province. South Korea and the United States believe the DPRK’s launch was successful. Although the missile flew only 933 kilometers, according to the Japanese media, the flight time of the missile was as long as nearly 40 minutes, significantly longer than that of the “Mars” 12 medium-range and long-range ballistic missiles successfully launched on 14 May This means that the new missile has a higher ballistic altitude and longer range. U.S. experts say the maximum altitude of the missile can reach 2,800 km, and the maximum range of up to 6,700 km when using normal trajectory.
