===Naval Air Station Tillamook===
The Tillamook airbase for [[non-rigid airship|blimps]] was commissioned on December 1, 1942, as U.S. [[Naval Air Station Tillamook]]. The two wooden hangars used to house these airships were decommissioned after [[World War II]] and deeded to Tillamook County. One of the hangars (Hangar B) is a national historic landmark and the location of the [[Tillamook Air Museum]]. The other hangar, (Hangar A) burned down in 1992.

The U.S. [[Mount Hebo Air Force Station]] was a [[Cold War]] air defense installation from 1956 to 1980. Located south of Tillamook, at the top of {{convert|3154|ft|m|adj=on}} high [[Mount Hebo]], Air Force radars operated by the [[689th Radar Squadron]] and the [[14th Missile Warning Squadron]] were essential parts of the nation's integrated air defenses. The large [[radome]]s protecting the radars from adverse weather effects could be seen silhouetted against the sky from most of Tillamook County.

Development along [[U.S. Route 101]] to the north of Tillamook during the last part of the 20th century has blocked part of the [[flood plain]] of the [[Wilson River (Oregon)|Wilson River]], contributing to repeated winter flooding in the city. Until the late 1950s there was a dredge used by the city to keep the slough's deeper.
