In the first US “salvo” test of ground-based missile interceptors, two interceptors were launched from Vandenberg Air Force Base in California on March 25, 2019. They successfully intercepted a “threat-representative” ICBM target launched from a test site on Kwajalein Atoll in the Marshall Islands.
