About this Unit
The Naval Ammunition Depot (NAD) was established during World War II to meet the United States Navy’s urgent need for a centralized facility to store, assemble, and distribute naval munitions. Located at various key sites across the country, such as Hastings, Nebraska, these depots played a crucial role in supplying ammunition to the Pacific and Atlantic fleets. During the war, the NADs operated around the clock, employing thousands of civilians and military personnel to ensure a steady flow of ordnance. After the war, many depots were gradually decommissioned or repurposed, but their legacy remains a testament to the logistical backbone that supported American naval operations during times of conflict.
Historical Facts
•
Massive Scale During WWII: The U.S. Navy established dozens of Naval Ammunition Depots (NADs) across the country during World War II, with some facilities spanning thousands of acres, such as the Hawthorne Naval Ammunition Depot in Nevada, which became the world’s largest.
•
Secret Storage: Many NADs were strategically located inland, far from coastlines, to minimize the risk of enemy attack and to keep ammunition storage locations secret and secure.
•
Women in the Workforce: During WWII, thousands of women were employed at NADs, filling vital roles in ammunition production and handling as part of the war effort.
•
Explosive Accidents: The work at NADs was extremely dangerous. Notably, in 1944, a deadly explosion at the Port Chicago Naval Magazine in California killed 320 sailors and civilians, leading to changes in safety practices and influencing the civil rights movement.
•
Support for Every Conflict: NADs have supplied ammunition for every major U.S. conflict since World War I, including Korea, Vietnam, and beyond, playing a critical logistical role.
•
Camouflage and Deception: Some depots were camouflaged or disguised from the air during wartime, using paint and fake buildings to confuse enemy reconnaissance.
•
Rail Networks: Many NADs operated extensive internal railroad systems, sometimes with hundreds of miles of track, to safely move munitions between storage bunkers and loading docks.
•
Environmental Legacy: Decades of ammunition storage and disposal have left some former NAD sites with environmental contamination, requiring ongoing cleanup and remediation efforts.
•
Decommissioning and Repurposing: Many NADs have been closed and repurposed since the Cold War, with sites converted into industrial parks, wildlife refuges, and even museums.
•
Role in Nuclear Weapons: Some NADs handled and stored components for nuclear weapons during the early years of the atomic age, making them key facilities in the U.S. nuclear arsenal.
