The Madison, Miss.-based subsidiary will upgrade engines, avionics and related components of 119 TH-57 Sea Ranger helicopters.
Work under the indefinite-delivery/indefinite-quantity contract will occur at the Naval Station Whiting Field in Milton, Fla.
The Pentagon expects work to finish by September 2012.
The Naval Air Systems Command in Patuxent River, Md. is the contracting activity.
The company’s link simulation and training division won a nearly $22 million contract in February to provide logistical support to an Air Force mission training center.
That contract includes priced options for up to 20 centers.
