How concrete giants saved Alaska from falling to Imperial Japan in WWII

Kodiak’s Wartime Transformation from Fishing Village to Fortress

In 1939, a tiny Alaskan fishing town got a shock when the U.S. Navy showed up. War was coming, and Kodiak stood in the path of Japan.

The Siems-Drake-Puget Sound firm won a $13 million contract that soon grew to $160 million as plans got bigger.

By 1942, over 3,500 men worked through blizzards, mud, and darkness to build what became America’s key northern naval base. After Japanese bombs hit Dutch Harbor that June, Navy Seabees rushed in to help.

Together, they turned wild shoreline into a fortress with airfields, docks, and gun batteries.

Today, Fort Abercrombie State Historical Park still guards these stories behind its concrete bunkers and hidden gun emplacements.

Siems-Drake Company Started Building on Kodiak in 1939

The Navy began a huge Alaska project in September 1939.

They hired Siems-Drake-Puget Sound Construction Company, giving them $13 million to build naval air bases at Sitka and Kodiak.

Work at Kodiak started September 23 on what would grow into a naval base with an air station, submarine base, and supply buildings.

The small crew faced tough challenges in the remote fishing village without basic services. Worse yet, the island was covered in volcanic ash from Mount Katmai’s 1912 eruption, making the ground unstable.

Volcanic Ash Made Building a Nightmare

Construction teams fought through volcanic ash layers from 3 inches to 8 feet deep across Kodiak. This ash sat on soggy soil and rock, creating unpredictable ground with constant water problems.

Every nail, board, and worker had to come from the mainland by ship. The crews needed all types of skilled workers as they built a city from scratch.

Storms kept rolling in from the Gulf of Alaska, slowing progress.

Workers pushed ahead despite freezing temperatures and strong winds that sometimes stopped work for days.

Navy Added Dutch Harbor to the Project in 1940

The contract grew much bigger in July 1940 when the Navy added Dutch Harbor and more Army buildings. The cost jumped to $160 million for all the expanded work.

Kodiak started as a naval air station in September 1939, then became a naval section base in January 1941. Plans now included six smaller bases around Kodiak and five more at Dutch Harbor.

The company rushed to bring in more workers to handle all the new building needs across Alaska.

Army Troops Moved into Temporary Housing in 1941

Fort Greely opened on April 3, 1941, when Battery C of the 250th Coast Artillery and a small Infantry group arrived on the ship USAT St. Mihiel.

This first military group included just 5 officers and 164 enlisted men from Coast Artillery plus 1 officer and 5 Infantry soldiers. Lieutenant Colonel Malcolm F. Lindsey took charge of the new Army post.

The troops landed on April 4 and moved into temporary housing at the Naval Air Station. Two days later, they set up their guns at nearby Buskin Flats while waiting for permanent forts.

Construction Crews Grew to 3,500 Men at Peak

Between October 1939 and April 1943, about 880 construction workers on average worked on the Kodiak projects.

The crews built three concrete runways, aircraft hangars, a submarine base with a floating drydock, and huge storage buildings.

Fort Greely grew to include housing for 10,829 enlisted men and 682 officers across 665 buildings. The Navy projects cost about $66.3 million while Army construction hit $28 million.

Harris Murdock Whiting led the work as field engineer, watching over jobs at many sites across Alaska’s tough landscape.

Pearl Harbor Attack Put Kodiak on High Alert

When Japan attacked Pearl Harbor on December 7, 1941, Kodiak Naval Operating Base already served as America’s main advance naval base in Alaska.

Fort Greely went on full alert with soldiers manning positions around the clock.

The base held an air station, submarine facilities, the North Pacific Force headquarters, and a joint operations center for Navy, Army, and Army Air Force units.

Flying boats launched patrols over the Gulf of Alaska, Bering Sea, and North Pacific Ocean. The entire base went dark when news of the Japanese attacks reached Alaska.

Japanese Bombers Hit Dutch Harbor But Missed Kodiak

Japanese planes bombed Dutch Harbor in June 1942 and took over the Alaskan islands of Kiska and Attu. Kodiak prepared for attack, but the Japanese never came.

Army bombers from Kodiak took off to fight enemy forces attacking Unalaska in the Aleutians. After the Dutch Harbor bombing, the Navy sent Seabee battalions to help the civilian construction teams.

Workers hurried to finish defensive positions and facilities, knowing they now built in a war zone with real threats just hundreds of miles away.

Fort Abercrombie Protected Kodiak’s Northern Approach

The Army built an 8-inch gun battery north of Kodiak at Miller Point in early 1943. They called it Fort Abercrombie and made it part of Fort Greely in April 1943.

Two other posts also opened: Fort Tidball on Long Island and Fort J.H. Smith at Chiniak. The Army put radar sets at all three spots, using SCR-296 models plus an extra SCR-582 at Fort Tidball.

The Harbor Defense system linked everything with 196,000 feet of underwater cable and 319,000 feet of underground cable to track enemy ships.

Thousands of Workers Built Massive Facilities

The workforce reached 3,508 men at its peak in December 1942.

They built 13 small boat docks and several major piers for large ships, including an 800-foot cargo pier. Fuel storage held over 180,000 barrels in both underground and above-ground tanks.

Cold storage buildings provided 111,350 cubic feet of freezer space across four separate buildings.

Workers carved out more than 166 miles of gravel roads throughout the base, connecting all facilities across the rugged island.

Seabees Took Over All Construction in Spring 1943

The Navy’s 4th Construction Regiment took control of all building projects except dredging on April 1, 1943. This regiment included the 38th, 41st, 43rd, and 45th Battalions of the famous Seabees.

When the civilian contractors left, they had finished about 72 percent of the planned work. The Seabees completed the unfinished projects and improved existing facilities while keeping the base running.

By the time the civilian workers departed, they had used construction materials and equipment worth about $25 million to transform the remote island.

Kodiak Became America’s Northern Shield Against Japan

From 1943 through 1945, Seabees finished the remaining construction while handling all maintenance and salvage operations. The base served as headquarters for the Aleutian Campaign against Japanese forces.

Submarines and ships from Kodiak played key roles in pushing Japanese forces out of the North Pacific.

The Royal Canadian Air Force stationed Bolingbroke bombers at Kodiak for patrols over the Gulf of Alaska and Bering Sea.

The base functioned as America’s northernmost Pacific defense stronghold throughout the war, a remarkable transformation from the tiny fishing village it had been just four years earlier.
