As the New England Air Museum continued to grow into its third decade, it became apparent that more space was needed for exhibits.
The museum boasted an exhibit hangar, restoration hangar, and a storage building, but by 1990 more exhibit area was needed for the museum to reach its full potential.
The new building was dedicated on December 4, 1992. Nearly doubling the size of the museum, the Military Aviation Hangar added 37,000 square feet. Military aircraft were moved from the old exhibit hangar (now the Civil Aviation Hangar) into the new exhibit space. The new building not only added room for aircraft, but also expanded the gift shop space, office area, and provided the museum with a conference room. The dedication was a grand event with numerous speakers and guests. The building allowed NEAM to continue to expand both their collection and as an organization. Today, the Military Aviation Hangar is the first exhibit you see as you enter the museum, and provides a spectacular entrance for visitors.
