On July 8, 2000 (June 7, 2000 in the lunar calendar), the third test of the US National Missile Defense system failed. The U.S. Department of Defense announced on July 8, 2000 that the U.S. military conducted a third test of interception technology for the proposed National Missile Defense system missiles that day, but it failed. Kadish, director of the U.S. Department of Defense's Office of Ballistic Missile Defense Systems, said that at 0:19 am Eastern Time on the 8th, the U.S. military launched an improved "Minuteman II" intercontinental ballistic missile from Vandenberg Air Force Base in California. 21 minutes later, the US military launched another missile from the Marshall Islands, 6880 kilometers away, to intercept the target missile. According to the original plan, the interceptor missile should encounter the "incoming" missile 10 minutes after liftoff. However, there was no image of the two bombs colliding and exploding on the TV screen. "We didn't achieve an interception, which was disappointing," Kadish said. He said the warhead of the interceptor missile did not separate from the body because it failed to receive the required electronic signal. In this way, the target bomb was not hit. Kadish believes it will take a few days for the Pentagon to figure out the real reason for the test failure. The test was delayed for more than two hours due to technical problems. A senior Russian Foreign Ministry official said on the 8th that after the third missile defense system test conducted by the United States failed that day, the U.S. government should not make a decision to deploy a national missile defense system. According to the OTASS news agency, the senior official said that Russia has repeatedly told the United States that the deployment of the National Missile Defense System on U.S. territory is a serious breach of the Anti-Ballistic Missile Treaty signed in 1972, and puts Russia and the United States in reducing offensive strategic weapons. All agreements signed are threatened.
