More Ships Added to VA’s Vietnam Ship List
VA has updated the list of U.S. Navy and Coast Guard ships that operated in Vietnam, adding 47 more vessels and expanding information for others. The list can help Vietnam-era Veterans find out if they qualify for presumption of Agent Orange exposure when seeking VA disability compensation for herbicide-related diseases.
“Agent Orange is the name given to a blend of herbicides the U.S. military sprayed from 1962 to 1971 during Operation Ranch Hand in the Vietnam War to remove foliage that provided enemy cover.
The name “Agent Orange” came from the orange identifying stripe used on the 55-gallon drums in which it was stored.
Tactical herbicides also were used, tested, and stored in areas outside of Vietnam. Learn
how Veterans may have been exposed to Agent Orange and other herbicides during military service, including outside Vietnam.
Agent Orange Active Ingredients and Characteristics
The two active ingredients in the Agent Orange herbicide combination were equal amounts of 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), which contained traces of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).
The dioxin TCDD was an unwanted byproduct of herbicide production. Dioxins are pollutants that are released into the environment by burning waste, diesel exhaust, chemical manufacturing, and other processes. TCDD is the most toxic of the dioxins, and is classified as a human carcinogen by the Environmental Protection Agency.
Agent Orange dries quickly after spraying and breaks down within hours to days when exposed to sunlight (if not bound chemically to a biological surface such as soil, leaves and grass) and is no longer harmful.”
Agent Orange: Exposure during Military Service
Part of the United States’ strategy in Vietnam was to conduct an herbicide program to remove foliage providing cover for the enemy. Agent Orange was the most widely used of the herbicide combinations sprayed. Agent Orange and other herbicides used in Vietnam were tested or stored elsewhere, including some military bases in the United States.
When and Where Agent Orange Was Sprayed in Vietnam
The U.S. military herbicide program in South Vietnam took place between 1962 and 1971. Herbicides were sprayed in all 4 military zones of Vietnam. More than 19 million gallons of various herbicide combinations were used. Agent Orange was the combination of herbicides the U.S. military used most often.
Heavily Sprayed Areas
Heavily sprayed areas included:
Inland forests near the demarcation zone
Inland forests at the junction of the borders of Cambodia, Laos, and South Vietnam
Inland forests north and northwest of Saigon
Mangrove forests on the southernmost peninsula of Vietnam
Mangrove forests along major shipping channels southeast of Saigon
Exposure to Agent Orange in and Outside Vietnam

Herbicide Tests and Storage Outside Vietnam
Possible exposure due to herbicide tests and storage at military bases in the United States and locations in other countries
Agent Orange Residue on Airplanes Used in the Vietnam War
Possible exposure of crew members to herbicide residue in C-123 planes flown after the Vietnam War.
