Chicopee, Massachusetts — Westover Air Reserve Base formally opened a 105,000-square-foot, high-bay inspection hangar on September 10 to support major maintenance of the Air Force’s C-5M Super Galaxy fleet.
The U.S. Army Corps of Engineers reported the project value as $52 million. Construction began in June 2021 and was completed in April 2026 after relocation of a government vehicle fuel station and demolition of a 70-year-old hangar. Burns & McDonnell served as designer of record; Cianbro leadership participated in the ribbon cutting, although the USACE story did not explicitly state the construction-award role.
About 200 members of the 439th Maintenance Group are expected to work in the facility. The hangar includes offices, restrooms and a sheet-metal shop and allows Westover to conduct exhaustive isochronal inspections indoors. Those inspections occur every 420 days and can take up to three weeks; Westover is one of two bases able to perform them.
The facility is complete and the source announced no further construction milestone or open procurement. The associated Air Force photo page carries an older $43 million title, while the later USACE project account reports $52 million; this article uses the USACE figure and preserves that source discrepancy in the review record.
