ICBM launch is scheduled for today from Calif.

An operational test launch of an unarmed Minuteman III intercontinental ballistic missile was scheduled for today, between 3:01 a.m. and 9:01 a.m. PDT from Vandenberg AFB, Calif.

The missile’s unarmed reentry system was expected to travel approximately 4,200 miles to the Kwajalein Atoll in the Marshall Islands.

“Every test launch provides an opportunity to demonstrate the readiness, effectiveness and accuracy of the weapon system,” said Col. Lance Kawane, 576th Flight Test Squadron commander. “A tremendous amount of teamwork is involved in conducting the test launch mission.”

The launch team, under the direction of the 576th FLTS, includes Airmen from the 91st Missile Wing, Minot Air Force Base, and the 90th Missile Wing, F.E. Warren AFB, Wyo.

Air Force Global Strike Command’s 576th FLTS is responsible for tracking and telemetry systems on the missile, which collect mission data and ensure safety requirements are met.
