The award for continued maintenance, repair and overhaul services at the U.S. Coast Guard Aviation Logistics Center in Elizabeth City, N.C., is for one year with four one-year options.
If all options are exercised, the value of the award could be worth $200 million.
"We look forward to renewing our commitment to provide safe, on schedule, mission-ready aircraft for our valued Coast Guard customers with the highest quality workmanship to meet all mission requirements," said Don Davis, vice president of operations for DRS's Technical Services group.
"It is a privilege to support the men and women of the USCG and we take great pride in our service and delivery of aircraft ready to fly the mission.
"Over 240 DRS employees contributed to this award by performing with excellence over the past 41 months."
DRS, a U.S. subsidiary of Italy's Finmeccanica, operates two MRO facilities -- each is more than 100,000 square feet – at its North Carolina facility.
