Leaders of the 439th Airlift Wing unveiled a new $43 million regional isochronal inspection hangar at Westover Air Reserve Base, Mass., Sept. 10, 2026, expanding the Air Force’s capacity to sustain readiness across the C-5M Super Galaxy fleet.

Military members, elected officials and community partners attended the ribbon-cutting ceremony marking the opening of the 94,000-square-foot facility. The hangar replaces a structure built more than 70 years ago for the B-36 Peacemaker and provides Patriot Wing maintainers with a modern, purpose-built environment for conducting comprehensive, time-based aircraft inspections.

“Investing in this facility is really about investing in our Airmen, our community and our mission,” said Col. Christopher Holland, 439th Airlift Wing commander.

The Patriot Wing operates at one of only two Air Force installations capable of performing regional isochronal inspections on the C-5M. The program supports aircraft assigned throughout the Air Force, helping preserve the strategic airlift capability needed to project, connect, maneuver and sustain the Joint Force.

“We open a really large door,” Holland said. “The future of mobility for the United States will pass through it every few weeks.”

During an isochronal inspection, maintainers disassemble and examine major portions of an aircraft, look for damage and complete a prescribed series of maintenance checks. Each inspection generally takes two to three weeks.

Col. Jordan Murphy, 439th Maintenance Group commander, said maintenance requirements have increased as the C-5 fleet has aged. Although the new hangar is not expected to shorten the prescribed inspection process, it will increase capacity and improve the precision, consistency and quality of the work.

Once operations are fully established, Patriot Wing maintainers expect to complete approximately 17 to 19 inspections annually.

“This is a world-class facility supporting the entire C-5M enterprise,” Murphy said.

The hangar expands available workspace and incorporates equipment designed to improve maintenance safety and workflow. Its features include an overhead crane capable of lifting 2,000 pounds, built-in aircraft power, an advanced fall-prevention system, integrated sheet-metal work areas and upgraded workstations.

The new facility provides infrastructure designed for the size and maintenance requirements of the C-5M while supporting Air Force efforts to balance immediate readiness with long-term modernization.

“For years, our maintainers accomplished world-class work in what is now a 70-year-old hangar,” Holland said. “Now, with this $43 million high-bay facility, our maintenance professionals have a modern facility with which they will meticulously care for each and every aircraft that passes through it.”

The project developed over nearly 20 years through the efforts of successive wing leaders, maintenance professionals, civil engineers, congressional partners and community advocates.

Murphy, who has been involved with the project for more than a decade, credited Patriot Wing maintainers, civil engineers, the U.S. Army Corps of Engineers, construction teams and other partners with bringing the facility to completion.

U.S. Rep. Richard E. Neal has supported the project since its earliest stages. During the ceremony, Neal discussed the congressional process required to authorize and fund the facility and the installation’s longstanding importance to national defense.

“This is a terrific moment for Chicopee, a terrific moment for Western and Central Massachusetts, but it’s also a terrific moment for the United States of America,” Neal said.

The facility also demonstrates the Air Force Reserve’s role as an operational force advantage. By conducting inspections on C-5Ms assigned throughout the Total Force, Patriot Wing Airmen provide experienced, accessible and integrated maintenance capability beyond their locally assigned mission.

“This facility belongs to you,” Holland told the maintainers. “Your work keeps America’s global reach ready, responsive and unmatched.”

The ceremony occurred one day before the 25th anniversary of the Sept. 11, 2001, terrorist attacks and during the year marking the nation’s 250th anniversary. Neal recognized the service of military members, law enforcement officers, firefighters and emergency medical personnel and reflected on the military’s role in defending the nation.

For the Airmen performing the inspections, the new facility’s mission remains focused on returning safe, reliable aircraft to service.

“These inspections keep our aircraft mission-ready,” said Senior Airman Theodore Davis, crew chief, 439th Maintenance Squadron crew chief. “We make sure what’s broken is fixed so the aircraft can go back out and accomplish whatever mission the Air Force calls for.”

By sustaining C-5Ms from across the Total Force, the Patriot Wing provides the strategic depth and rapid global mobility needed to respond to crises, deter aggression and project American strength worldwide. The new facility will help keep that capability ready whenever the nation calls.
