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. This photo shows the launch of the “lead” interceptor, which destroyed the missile’s reentry vehicle. The “trail” interceptor struck the remaining “most lethal object” it could find.
