The Boeing Company C-17 Hangar

The U.S. Air Force’s C-17 airlifter is capable of carrying combat-ready military units, including tanks and artillery, almost anywhere in the world. The 175-foot-long C-17 has a wingspan of 165-feet and a tail height of 55-feet.

Project Description: 

The U.S. Air Force’s C-17 airlifter is capable of carrying combat-ready military units, including tanks and artillery, almost anywhere in the world. The 175-foot-long C-17 has a wingspan of 165-feet and a tail height of 55-feet.

This large and advanced aircraft is assembled in a 1.1-million square foot state-of-the- art facility, which was designed and constructed by The Austin Company. Austin’s assignment involved adding 700,000 square feet to an existing 400,000 square foot building previously used to build the DC-10 jet airliner. Austin’s design team wrapped the new space around the old in a u-shaped configuration.

The magnitude of the C-17 plant can be gauged by its capacity to handle final assembly of 10 airlifters simultaneously and in just one third of its total area. Assembly bays are 780-feet long, 202-feet wide and 100-feet high to the roof parapet. The interior height is 80-feet to the bottom chord of the truss.

The scale of the building is also suggested by its massive hangar doors, the largest concentration in the world in one building. The building’s size is also reflected in the 2.8- miles of utility trenches and tunnels and an extraordinary crane system used to move major subassemblies.

Austin completed construction on a fast-track schedule in less than 18 months.
