General Atomics Aeronautical Systems Inc. received a $462.1 million contract modification from the U.S. Army for a year’s worth of services for the Army’s Gray Eagle unmanned aircraft.

The deal covers maintenance and repair support for Gray Eagle aircraft in the field.

In a statement earlier this month, GA-ASI said it has delivered 165 model MQ-1C Gray Eagle aircraft to its Army customer. The unmanned aircraft can stay aloft for 25 hours and carry Hellfire missiles.

Work will be performed in Poway and will last through Oct. 23, 2018.

The U.S. Army Contracting Command of Redstone Arsenal, Alabama, awarded the contract, announced on Oct. 23.
