Engility Holdings is to deliver aircraft and weapons system engineering support to the U.S. Navy under a 21-month contract.

The award, granted by the Naval Air Warfare Center Aircraft Division, is an indefinite-delivery/indefinite-quantity contract with a total value of $71 million.

"With our engineering expertise and proven performance, Engility is best positioned to analyze, test, and help manage the myriad of naval aircraft and weapon systems," said Engility CEO Lynn Dugle. "Working side-by-side with the Navy, we can help ensure fleet safety and mission success."

Engility said its work will include assessment of the technical performance, suitability and risks of aircraft, weapon and integrated systems. It will also perform systems engineering, analysis, development, integration and testing for the introduction of warfare systems into naval aircraft, including direct systems engineering support throughout the full life cycle of a weapon system -- from concept development through disposal for naval aircraft.
