Facility Opened In 1988, Closed By BRAC

Members of the Physiological Training Center concluded 22 years of centrifuge training at Holloman AFB in New Mexico with its final spin Oct. 27. The culmination of the centrifuge training mission at Holloman AFB was directed by the Department of Defense Base Realignment and Closure of 2005, which announced the consolidation of fighter acceleration training and aerospace medicine research at Wright-Patterson AFB, Ohio, where a new centrifuge is being built.

"The unique thing about the Wright-Patterson (AFB) device is that we're going to combine the aircrew training mission and the research mission into one, so we'll use the same device and the same mission at once," said 1st Lt. Jennifer Smith, the commander of the Physiological Training Center.

Since the centrifuge was first certified at Holloman AFB in 1988, it has been the only Air Force-owned human centrifuge used for aircrew training.  Operated by the U.S. Air Force School of Aerospace Medicine, the centrifuge was used as a training device to expose pilots to a high level of G-forces -- a measurement of an object's acceleration -- which aircrews encounter in high-performance aircraft, the lieutenant said. "We configured the centrifuge for anything from the T-38 (Talon) to the F-22 (Raptor) and every high-G aircraft in between," she said. "The primary reason we conduct centrifuge training is to prevent G-LOC, which is gravity-induced loss of consciousness. It can occur when pilots are exposed to high Gz."

Upon its last spin, Holloman AFB's centrifuge had been used to train nearly 32,000 students, including servicemembers from all branches, North Atlantic Treaty Organization troops and members of allied forces. "(We had the capability to train) all of the USAF aircrew and NATO aircrews," Lieutenant Smith said. "We've trained folks from the Chilean air force. We've had folks from Italy, from Pakistan and most of our allied countries who don't have a centrifuge of their own."

The last student to spin in Holloman AFB's centrifuge pulled nine Gz in preparation for his upcoming assignment as an F-22 pilot at Langley AFB, VA. He said he enjoyed the ride and was also excited to be part of such a momentous occasion. "It's a pretty cool feeling," said Capt. George Cannon, the 48th Operations Support Squadron Tactics Division chief from Royal Air Force Lakenheath, England. "This centrifuge has a lot of history so it was a pretty cool thing to be the last person to go through, but I'm sure the new one they're building at Wright-Patterson (AFB) will be even better."

Captain Cannon was one of many students who spent a few hours in a classroom and a few minutes in the centrifuge that day as part of the final class. In contrast, many of the physiology technicians spent years teaching in the classroom and working with the centrifuge. For them, the last spin at Holloman AFB was bittersweet. "The last centrifuge mission at Holloman is pretty unique in that we've been training here for over 20 years," Lieutenant Smith said. "I've only seen the last three years of it, so I haven't had as great of a tie as some people who've worked with it since it was put in the ground in 1988, but I'm really excited for the future of the centrifuge mission and the brand new device that's being built at Wright-Patterson (AFB)."

According to an article on the official Wright-Patterson AFB website, installation of the new centrifuge has already begun and construction and certification is slated to be complete in 2012. Until the device is certified, centrifuge training will be performed by contractors at existing facilities at Brooks City-Base, TX.

Although the final spin marked the end of this mission at Holloman AFB, Lieutenant Smith said a couple members of the Physiological Training Center will remain here to embark on a new primary mission focused on optimizing human effectiveness. "We will be a two-man team to conduct the physiology mission as the Holloman Aerospace and Operational Physiology Training team," she said. "We will pretty much be the human performance gurus for Holloman so we'd like to integrate with different squadrons and see what we can do to help maximize human performance on the base."
