The Army says all 9,600 GB-filled 155 millimeter shells have been safely disposed of at the Anniston Chemical Weapons Incinerator.
Along with all the 155 millimeter projectiles disposed of, nearly all of the M-55 rockets and warheads and most of the eight-inch projectiles have been disposed of since operations began at the facility in August 2003.
According to Timothy Garrett, government site manager, the team expects to wrap up the GB disposal campaign by the end of the year.
He said maintenance and retooling work is under way and disposal operations will likely resume in early July.
Since the three different types of projectiles vary in size and weight, technicians have to realign some of the facility's equipment before processing 105-milimeter projectiles.
Garrett said employees have successfully emptied 30 storage igloos.
