California, around 11 p.m. local time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThere were no injuries in the explosion and the debris was contained to the immediate vicinity of the launch pad,\u201d the base said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Officials will investigate the cause of the mishap.<\/p>\n\n\n\t<aside class=\"smg-interstitial-link

Deterrent.<\/p>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/a>\n\t<\/aside>\n\t\n\n\n<p class=\"wp-block-paragraph\">The Minotaur II+ combines parts of decommissioned Minuteman intercontinental ballistic missiles and an upper segment of the current Minuteman III nuke to create a missile used for suborbital test launches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vandenberg routinely holds live tests of unarmed missile bodies \u2014 without a nuclear warhead inside \u2014 to check how the aging ICBMs are faring and to vet new technology.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this case, the Air Force Nuclear Weapons Center said the practice missile was carrying a Mark 21A reentry vehicle, or the part of a nuclear weapon that would hold a real warhead.<\/p>\n\n\n\n<p

Japan, in 1945 \u2014 on the LGM-35 Sentinel missile now in development at Northrop Grumman.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe W78 is one of the oldest warheads in the stockpile, and the W87-1 modification program provides improvement in warhead security, safety and \u2026 control,\u201d according to the Energy Department, which manages the program.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The updated reentry vehicle, which carries the warhead to the edge of space in an arc before gliding down to its target, is also expected to accommodate future warhead designs on the new ICBMs in the coming decades.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sentinel ICBMs will replace the 400 nuclear missiles in underground silos across Montana, Wyoming and North Dakota in the late 2020s.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Officials are investigating the cause of the mishap, which did not injure
