Tetra Tech Awarded $356 Million FAA Navigation Technical Assistance Contract

Tetra Tech, Inc. (NASDAQ: TTEK) announced today that it has been awarded a $356 million single-award contract to provide engineering and technical support services to the Federal Aviation Administration (FAA). Under the five-year Navigation Technical Assistance Contract II (NAVTAC II), Tetra Tech will support the FAA in the planning, research, development, implementation, maintenance, and decommissioning of the FAA’s navigation, landing, and lighting systems.

The U.S. commercial aviation industry is expected to carry one billion passengers annually by 2021. As the number of passengers continues to grow, the FAA faces an increasingly complex challenge in ensuring that flights are safe, efficient, and cost-effective. Under NAVTAC II, Tetra Tech will assist the FAA in addressing these challenges by helping the agency transition to an integrated ground- and space-based navigation systems architecture, as well as by supporting the FAA’s modernization initiatives, including its Next Generation Air Transportation System effort and its transition to Performance Based Navigation.

“Tetra Tech is a long standing FAA prime contractor, assisting in the implementation and deployment of satellite- and ground-based navigation technologies,” said Tetra Tech Chairman and CEO Dan Batrack. “We are pleased to continue to support the FAA’s modernization efforts under NAVTAC II.”
