An unarmed Minuteman III ICBM lifted off from Vandenberg AFB, Calif., en route to the Kwajalein test range in the central Pacific during a routine test of the accuracy and reliability of the Minuteman weapon system, announced officials with the base’s 30th Space Wing. The Feb. 25 mission “proceeded as planned,” they said.
The F-35 Joint Program Office has officially announced plans to issue multiple sole-source contracts to Pratt & Whitney to upgrade the fighter’s F135 engine—a widely expected move after Pentagon officials indicated they would do so earlier this year instead of developing an entirely new engine.
