The Defense Department said Tuesday the modification exercises an option for L3’s Vertex Aerospace business to the service branch maintain and perform support work on TH-57 helicopters through May 2018.
TH-57 is a modified version of the Jet Ranger 206 platform and designed to aid chase, photo, training and utility missions.
Vertex Aerospace will perform work under the modification at the Naval Air Station Whiting Field in Milton, Florida.
The Navy awarded Vertex Aerospace a $56.2 million modification in May 2015 to support 119 TH-57 trainer aircraft.
