Last U.S. stockpile of deadly VX agent destroyed

LOUISVILLE, Ky. (AP) — The last stockpiles of a deadly chemical agent in the U.S. have been safely eliminated, according to Kentucky officials in charge of destroying the Cold War-era weapons.

The final M55 rocket containing VX nerve agent was destroyed Tuesday at the Blue Grass Chemical Agent plant. Officials at the Kentucky plant began disassembling about 18,000 of the rockets and draining the VX agent in July, according to a news release from plant officials.

Candace Coyle, the plant’s project manager, said Wednesday the nation’s entire stockpile of VX nerve agent “is now completely destroyed.”

VX is considered the deadliest of the chemical agents that was produced by the U.S., much of it in the 1960s. It has a consistency similar to motor oil and even a tiny amount causes victims’ bodies to flood with fluids, producing a feeling of drowning before death. Officials in 2017 declared that assassins used VX agent to kill the brother of North Korean leader Kim Jong Un in a Malaysian airport.

The Kentucky Army depot still has 277 tons of other chemical agents left to be destroyed, after beginning with more than 520 tons of VX, GB and mustard agent that was in storage for decades. Officials said it all should be gone by next year after it began eliminating its mustard agent stockpiles in 2019.

“After more than a half century of chemical weapons storage in central Kentucky, the final chapter at Blue Grass Army Depot will soon begin,” said Col. Stephen Dorris, commander of the depot in central Kentucky, where the plant is located.

The mustard agent campaign finished in September. The plant also destroyed 4,000 projectiles with GB nerve agent in the first half of 2020. Another 13,000 155mm projectiles with VX agent were destroyed from January to May 2021.

The military had planned decades ago to destroy the weapons in Kentucky by burning them, but after concerns from residents and environmental groups, a plan was settled on to use water and chemicals to neutralize the agents.

There are also chemical weapons being destroyed at an Army facility in Pueblo, Colorado. The stockpiles at the two sites accounted for the last 10% of an original stockpile of more than 30,000 tons of chemical weapons in the U.S. The Army used incineration methods to destroy the weapons at other sites.
