Hangar One Restored

Hangar One, a historic landmark at Moffett Federal Airfield in California, has been fully restored by Planetary Ventures. The restoration work included remediation, clean-up, and recladding of the siding and roof, as well as structural upgrades. The hangar was originally built in 1933 for the USS Macon airship and has been a key part of the region's early aviation history.

The restoration project began in 2014 when NASA signed a lease with Planetary Ventures to operate Moffett Federal Airfield and rehabilitate Hangar One. The team removed toxic chemicals from the hangar, including PCBs and asbestos, and made several structural upgrades to ensure the hangar's long-term operational integrity.

The restoration was completed in December 2025, and the hangar has been restored according to the U.S. Secretary of the Interior's Standards for Rehabilitation of historical buildings. Hangar One is listed in the National Register of Historic Places and is designated as a Naval Historical Monument and a California Historic Civil Engineering Landmark.
