Diagrams of Munitions at Pueblo Chemical Depot
Figures A-1 through A-3 are drawings of the 105-mm projectile, 155-mm projectile, and 4.2-inch mortar projectile. Figure A-4 shows a boxed 105-mm projectile. Information is also included on the size, weight, energetics, and packaging of each projectile.
The stockpile inventory at Pueblo Chemical Depot consists entirely of munitions containing mustard agent. Most of the projectiles contain mustard agent HD (distilled bis(2-chloroethyl) sulfide). Some contain mustard agent HT, a 60:40 eutectic mixture of HD and bis[2-(2-chloroethylthio)ethyl] ether. All of the munitions may contain some degradation products and inorganic residues.
FIGURE A-1 A 105-mm howitzer projectile. Note: Some M60 105-mm cartridges have been reconfigured and therefore will not have propellant in the box with the projectile. For those that still have propellant, there will be M67 propelling charges containing M1 propellant in the box. SOURCE: Adapted from U.S. Army, 1977.
FIGURE A-2 A 155-mm howitzer projectile. Note: M110 projectiles have been stored separated from their propellant.
SOURCE: Adapted from U.S. Army, 1977.
FIGURE A-3 A 4.2-inch mortar cartridge. Note: The M6 propelling charge comprises 25.5 increments of M8 sheet propellant arranged in the following order: one ½ increment, four 5-increment bundles, and five single increments. 4.2-inch cartridges/mortars will be reconfigured as projectiles. Most 4.2-inch cartridges will also be defuzed. SOURCE: Adapted from U.S. Army, 1977.
FIGURE A-4 Boxed 105-mm projectile showing the casing, the propellant bags, and other dunnage in the fiberboard tube.
