About Tillamook Blimp Hangar
Hangar B in Tillamook is so large that calling it a building feels inadequate. The wooden structure stretches 1,072 feet long, rises 192 feet high, spans 296 feet across, and covers more than seven acres beneath a single roof.
The U.S. Navy built two enormous hangars at Naval Air Station Tillamook during World War II to house K-class patrol blimps. Each airship measured more than 250 feet long, so ordinary aircraft buildings were useless. Hangar B was completed in 1943 using more than 3.2 million board feet of Pacific Northwest lumber.
Six door sections, each weighing about thirty tons, created an opening large enough for the airships. Catwalks run more than a hundred feet above the hangar floor. Its twin, Hangar A, was destroyed by fire in 1992, leaving Hangar B as the surviving giant.
Tillamook Air Museum later occupied the structure and interpreted both aviation history and the building itself. As of September 2026, the museum’s official site states that it is closed until further notice because of storm damage. Visitors should not assume interior access and should check the official website for reopening information before making a special trip.
