Red Hill Underground Fuel Storage Facility, Military fuel storage facility in Moanalua, Hawaii.
Red Hill is an underground fuel storage facility operated by the U.S. Navy near Moanalua on Oahu. It consists of twenty steel-lined storage tanks connected by pipelines that distribute fuel to naval installations and ships.
The U.S. Navy built this facility between 1940 and 1943 to protect its fuel supply from aerial attack. The project was part of military expansion in the Pacific during World War II.
The facility has shaped how people view military infrastructure in Hawaii and influenced relations between the Navy and local Hawaiian communities. Its presence on the island remains a symbol of this military history.
Access is restricted to authorized military personnel since this is an active naval facility. The site is not open to the general public, so plan to view it from a distance if interested in its location.
The facility uses a gravity-fed system where fuel flows through several miles of underground tunnels directly to naval piers without requiring pumps. This ingenious design has kept the operation simple and reliable for decades.
