The Air Force had to call off at the last minute a planned July 19 launch of an unarmed Minuteman III ICBM at Vandenberg AFB, Calif. The flight was supposed to test the missile’s reliability, said the Air Force. The launch delay is expected to be brief, and the ICBM could fly as early as Thursday. The missile’s three warheads will be hurled toward a target in the Marshall Islands area. The launch authority is the 576th Flight Test Squadron at Vandenberg.
The Space Force is playing midwife to a new ecosystem of commercial satellite constellations providing alternatives to the service’s own Global Positioning Service from much closer to the Earth, making their signals more accurate and harder to jam.
