FORT SHAFTER, Hawaii — Army helicopters continued attempts Tuesday morning to contain a brush fire at a Hawaii training range that has already burned 570 acres since it began Monday.

The fire in the Schofield Barracks Range Complex was 50% contained as of Monday evening, Army Garrison Hawaii said in a social media post Monday. The range complex is roughly 2,800 acres.

Federal firefighters are also working to contain the wildfire.

Army air crews operating UH-60 Black Hawk and CH-47 Chinook helicopters began dropping buckets of water on the blaze Monday and continued the work Tuesday morning, the Army said.

There is no immediate threat to homes or facilities, according to the Army.

The helicopter crews are transporting water with so-called Bambi buckets, which are lightweight, collapsible containers made specifically for aerial firefighting. They hold about 660 gallons of water.

Brush fires are commonplace on the Hawaiian Islands.

In January, a road just south of Schofield Barracks was closed for several hours as firefighters responded to a wildfire that was extinguished within a day.

In August, the Honolulu Fire Department battled three separate wildfires in the grassy highlands of central Oahu.

Several thousand acres of grassland have burned in recent years on and near the Army’s 132,000-acre Pohakuloa Training Area on the Big Island.

A series of wildfires on Maui in early August 2023 turned deadly as high winds swept flames through the town of Lahaina, decimating it and killing 102 people.
