Boeing has received a $139.8 million contract to provide four MH-47G Block II Chinook helicopters to the U.S. Army Special Operations Aviation Command.

“The Army uses the MH-47G for some of its most difficult and challenging missions,” said Pat Donnelly, director, H-47 Domestic and Foreign Military Sale Programs.

“By incorporating key Block II features we significantly extend the service life, enhance performance, and maintain Chinook’s position as the world’s preeminent special operations helicopter.”

These helicopters mark the start of a Block II production run expected to extend into the late 2020s.
