Press Release

HOUSTON Ð (August 15, 2018) Ð KBR, Inc. (NYSE: KBR) announced today that its global government services business, KBRwyle, has been awarded a contract by the U.S. Naval Air Warfare Center Training Systems Division (NAWCTSD) to provide centrifuge-based training for all U.S. Navy and Marine Corps aircrew including the world famous flight demonstration squadron, the Blue Angels.

KBRwyle will conduct centrifuge-based flight environment training for approximately 600 students annually from the Navy's Blue Angels flight demonstration squadron, as well as the Chief of Naval Air Training, Naval Strike Air Warfare Center, and the Chief of Naval Air Forces and U.S. Marine Corps.

KBRwyle instructors will teach students about the physiological effects of acceleration and countermeasures used in a high-G environment. Students will receive classroom instruction as well as realistic, hands-on training in the company-operated centrifuge that generates acceleration forces equivalent to those experienced during flight.

KBRwyle will provide all personnel, resources, facilities, and maintenance for this training, and will support routine Navy inspections to ensure the safety of its operations.

This work will be primarily performed at KBRwyle's office in San Antonio, Texas. The period of performance for this single award, indefinite-delivery/indefinite-quantity (IDIQ) contract is five years.

"KBRwyle's training is critical in preparing aircrew for the extreme G-forces they'll encounter during flight," said Byron Bright, President, KBR Government Services U.S. "KBRwyle has been the exclusive provider of centrifuge-based acceleration training for all Navy and Marine Corps aircrew for the past five years, and we are proud to continue this work."

KBRwyle won the previous contract for this work in 2013, and continues to be the premier provider of high-G flight training to the Navy. It also conducts similar training for U.S. Air Force fighter pilots and combat systems officers.

KBRwyle is an industry-leader in human performance and extreme aviation testing for the Department of Defense and NASA. It operates multiple specialized test facilities dedicated to research, development, test and evaluation of critically important human performance issues and life support equipment.

Estimated revenue associated with this contract award will be booked into the backlog of unfilled orders for KBR's Government Services business segment.
