During World War II, it manufactured Composition B, a very powerful explosive mixture of RDX and TNT.
The facility was placed in standby status after World War II, producing only fertilizer, until it was reactivated in 1949 under the Holston Defense Corporation, a new subsidiary of Eastman Kodak.
It did not resume large-scale production until the mid-1960s when it was again modernized to produce large amounts of Composition B for the Vietnam War.
