Press Release

HOUSTON (June 28, 2018) KBR, Inc. (NYSE: KBR) announced today that the National Defense Industrial Association (NDIA) has selected KBRwyle engineer Freddie Lee as the 2017 Army Contractor Tester of the Year. The award was presented to Lee at the 33rd Annual National Test and Evaluation Conference near Naval Air Station Patuxent River, Maryland.

Lee received the award for his role as the test lead for the U.S. Army's Tactical Signals Intelligence Payload (TSP) program supporting the Program Executive Office (PEO) for Intelligence, Electronic Warfare and Sensors (IEW&S). Lee is a two-time recipient of the award, and the sixth KBRwyle employee to be recognized and awarded the NDIA's Tester of the Year award since 2004.

NDIA annually recognizes individuals who have made significant contributions in the field of test and evaluation with the Tester of the Year awards in three different categories: military, civilian, and contractor. Awardees are selected by the Office of the Secretary of Defense or one of the U.S. military's test and evaluation commands.

"We are proud of Freddie and the significant impact he has made on the U.S. armed forces," said Byron Bright, President, KBR Government Services U.S. "His meticulous standards for test and evaluation and unwavering dedication to the Army's mission reflect KBR's commitment to serve our customers."

As the test lead, Lee developed and maintained a dynamic, rigorous test program for the TSP, a next generation airborne intelligence, surveillance and reconnaissance (AISR) system operating on the U.S. Army's MQ-1C Gray Eagle Unmanned Aircraft System.

Lee conducted multiple developmental and operational test events for the Army program. He developed, coordinated, staffed, and received all necessary approvals for an out-of-cycle test resource plan and a Test and Evaluation Master Plan (TEMP) update.

These plans ensured the TSP program received critical test resources and, ultimately, helped validate the TSP system's capabilities and performance. Lee developed both plans in just over 90 days and executed more than 240 days of flight testing throughout FY2017.

A former U.S. Army test officer and current senior test engineer, Lee supports KBRwyle, KBR Inc.'s global government services business. KBRwyle is a leader of global Army readiness supporting personnel, platforms, equipment and systems, and is a top provider of engineering services to U.S. Army aviation.
