KBR is one of eight companies awarded a prime contractor position to compete for specific task orders on the $5B Air Force Contract Augmentation Program (AFCAP IV).

"Winning a position on AFCAP IV allows KBR the opportunity to continue its support of the Air Force customer in strategic locations worldwide, providing quality base life support and logistics for our U.S. military wherever they need us," said KBR Government Services President Andrew Pringle. "Through this contract, KBR will continue to differentiate itself as a preferred provider of services in contingency environments."

AFCAP IV, awarded by the 772nd Enterprise Sourcing Squadron, Air Force Installation Contracting Agency at Tyndall Air Force Base in Florida, will provide base life and operating support, logistics support, and construction services as needed to support the Air Force, Department of Defense, or any U.S. federal government entity performing contingency operations. Work will be performed at locations worldwide to be determined by individual needs. This work is expected to be performed over seven years, with funding allocated to orders on an as-required basis in support of the AFCAP scope of services.

Expected revenue associated with this multiple award IDIQ contact will be booked into backlog of unfilled orders for KBR's Government Services Business Segment as task orders are awarded throughout the contract period.
