VANDENBERG AIR FORCE BASE, Calif. (AP) — An unarmed Minuteman 3 intercontinental ballistic missile was launched from California early Tuesday on a test flight to a target in the Pacific Ocean, the Air Force Global Strike Command said.
The missile blasted off at 12:21 a.m. from Vandenberg Air Force Base and its three reentry vehicles traveled 4,200 miles (6,759 kilometers) to the Kwajalein Atoll in the Marshall Islands as part of a developmental test, the command said from Barksdale Air Force Base, Louisiana.
Test launches are essential to sustaining the aging Minuteman 3 nuclear weapon system, Col. Omar Colbert, the 576th Flight Test Squadron commander, said in a statement.
The Air Force said test launches are not a reaction to world events.
The launch calendars are developed three to five years in advance, and planning for individual launches takes six months to a year.
