Endicott Period

In 1897 Fort Stevens underwent a massive re-fortification program to improve coastal defense that resulted in the construction of 8 Endicott Period concrete batteries around the original site. Two other forts, Fort Canby and Fort Columbia, were built on the Washington side of the Columbia River to complete the Harbor Defense System.

The West Battery was built in 1898 with a total of six, 10" disappearing carriage rifles. The West Battery was later renamed, in three sections of two rifles each, Battery Mishler, Battery Walker and Battery Lewis. Battery Lewis and Battery Walker were traditional Endicott Period Batteries facing toward the Columbia River entrance. Battery Mishler was different in that the two, 10" rifles had a all-around field (ARF) of fire and could cover both the Columbia River entrance and the Pacific Ocean approaches. The six rifles of the West Battery were supplemented by two, 6" rifles of Battery Pratt.

Battery Russell was built to provide additional coverage of the Pacific Ocean approaches to the mouth of the Columbia with two, 10" disappearing carriage rifles. Battery Clark was built with eight, 12" mortars (later reduced to four) that could provide plunging fire with 1,000 pound shot on the decks of hostile ships in either direction.

World War II

Fort Stevens was significantly built up during World War II and had the distinction of being the only stateside installation attacked by enemy forces since the war of 1812 when a Japanese submarine I-25 fired 17 shells close to the fort. The fort did not return the fire because the submarine was out of range of Fort Stevens older guns. The submarine left without inflicting any damage.

After World War II Fort Stevens was deactivated and by 1947 all the armament had been removed.

In Sep 1950, just after the start of the Korean War, the Air Force established Fort Stevens Air Force Station (759th AC&W) on the Fort Steven post. The Air Force Station provided long range radar surveillance using CPS-5D and TPS-1B radar sets mounted on top of Battery Mishler. The unit headquarters was located in the "Guard House" and Battery Mishler served as the operations and maintenance center for the squadron.

Fort Stevens Air Force Station moved to Naselle AFS in Washington Feb 1952.

Oregon State Parks leased the old fort area in 1975 and continues restoring and interpreting the fort.


Location: Situated at the mouth of the Columbia River and located nine miles from Astoria in Clatsop County, Oregon.
