CDA Grid

This grid area is located sixteen miles north west of Dog Area. The facility consists of seven rows of hasty-type fixed fortifications with eleven located in each row. These fortifications are constructed on thirty-six foot centers. They consist of bunkers; one-man foxholes, covered, partly covered, and open; and two-man foxholes, covered and partly covered. The different types are scattered in a random pattern throughout the rows for variety.

The grid has a piped vacuum system and a 110-volt single phase control network to allow for obtaining sequential samples, both inside and outside the fortifications. Vacuum is supplied by two 132 cfm vacuum pumps and power by three 30 KW generators.

        The CDA grid is used primarily for the testing of chemical-filled artillery shells.

   The following diagram #1 is a layout of the fortification complex on this grid.
