Gen. Kevin P. Chilton has assumed command of the U.S. Air Force Space Command in a ceremony on June 26, presided over by Air Force Chief of Staff Gen. T. Michael Moseley.

Current and former national defense leaders, active and retired senior officers, community leaders and active-duty service members gathered at the parade field at Peterson Air Force Base to welcome the new AFSPC commander.

Chilton succeeded Gen. Lance W. Lord, who retired April 1.

Chilton is the first astronaut to earn a fourth star. He pinned on the rank of general in a promotion ceremony the morning of his assumption of command.

In his speech, Moseley illustrated Chilton's capabilities to lead the command.

"There is no one better prepared to lead Air Force Space Command today than General Kevin 'Chili' Chilton. Chili, you're a great commander, a great Airman, a great leader, a great astronaut – you know air and space power first hand. You understand the needs, the nuances of command, and you know the challenges ahead of us as an air and space force," Moseley said.

Chilton said he was excited and humbled to lead a "fantastic team" of total force military, civilian and contractors who deliver Air Force space capabilities for the defense of the nation.

"This command really is unique compared to every other major command, in my opinion," Chilton said. "I'm talking about the unique fact that every operational unit of this command is CHOP'd (change of operational control) to our nation's combatant commander for space (U.S. Strategic Command). We are in the fight, 24-7, 365 days a year."

Chilton spoke briefly about upgrading the Minuteman intercontinental ballistic missiles, prompt global strike, responsive space capabilities and bringing improved situational awareness and command-and-control tools to teammates who deliver space capabilities to the fight.

He also spoke about AFSPC assets being an "invisible force."

Chilton called the ICBM force the planet's most powerful strategic deterrent, existing out of sight and below the ground. The bits and bytes that transmit weather, warning, communications and navigation are transmitted through the ether to the end user, and the satellites are out of sight, but not out of mind, he added.

"To tell you the truth, I kind of like the idea of being invisible and powerful," Chilton said, "and that is exactly what you are. You are the power behind this great force."

Chilton said his commitment will be to remain focused on organizing, training and equipping the command to provide the asymmetric advantage Airmen bring to today's fight.

The general is a 1976 distinguished graduate of the U.S. Air Force Academy. He is a command astronaut pilot with more than 5,000 flight hours.

Chilton joined NASA in 1987. There, he flew three space shuttle missions on Atlantis and Endeavor and served as the deputy program manager for operations for the International Space Station program.

He now leads nearly 40,000 space and missile professionals who provide combat forces and capabilities to USSTRATCOM and North American Aerospace Defense Command.

Chilton is responsible for the development, acquisition and operation of the Air Force's space and missile systems.
