Operations

Operations at JPG centered on munitions testing. Over 7 million rounds were tested between 1941 and 1945, including cartridges, propellants, bombs, grenades, and high-explosive projectiles.

After World War II, testing activities were reduced and the site was placed on standby.

In June 1950, the outbreak of the Korean conflict prompted JPG's return to active status. Special production engineering tests, as well as research production tests, were conducted during the 1951 to 1955 period.

In July 1958, JPG was placed on standby status until 1961, when JPG was reactivated. At that time JPG added white phosphorus munitions to its mission.

Depleted uranium (DU) was added as a test item in 1984 under a license with the Nuclear Regulatory Commission. All DU testing at JPG was performed against soft cloth targets.

A total of approximately 25 million rounds were tested at JPG. Approximately 1.5 million rounds of high explosive unexploded ordnance (UXO) remain.

Operations also included a variety of industrial activities, such as weapons maintenance and repair and vehicle maintenance and storage.
