For decades, the VA denied Agent Orange benefits to Navy veterans who served offshore Vietnam — arguing that only veterans who set foot on Vietnamese soil were exposed to the deadly herbicide. The "Blue Water Navy Vietnam Veterans Act of 2019" (HAVEN Act) changed that permanently. Veterans who served in the territorial waters surrounding Vietnam are now entitled to the same Agent Orange presumptive conditions as their land-based counterparts. If you were denied before 2020, or if you've never filed, this guide covers everything you need to know.
A Blue Water Navy veteran is a veteran who served aboard U.S. Navy or Coast Guard vessels that operated in the open ocean waters — known as the "blue water" — off the coast of Vietnam during the Vietnam era. This is in contrast to "brown water" veterans, who served on inland waterways and rivers within Vietnam, and veterans who served on land in Vietnam.
Prior to the HAVEN Act, the VA's position was that only veterans who actually set foot on Vietnamese soil, or who served on vessels operating in the inland waterways, were presumed to have been exposed to Agent Orange. Blue Water Navy veterans — even those who spent months sailing through heavily contaminated waters — were excluded from Agent Orange presumptive benefits.
Scientific evidence consistently showed that ships in the coastal and offshore waters were exposed to Agent Orange runoff from rivers, contaminated drinking water (ships distilled seawater that carried herbicide contamination), and aerial drift. Congress ultimately agreed, passing the HAVEN Act in June 2019 with bipartisan support.
The Blue Water Navy Vietnam Veterans Act of 2019 (Pub. L. 116-23), signed into law on June 25, 2019, and effective January 1, 2020, created a new presumption of herbicide exposure for veterans who:
The law directed the VA to create a list of ships that operated in qualifying waters and to extend Agent Orange presumptive benefits to those veterans without requiring individual proof of actual herbicide exposure. This is a major shift — under the old rules, Blue Water veterans had to prove specific exposure, which was nearly impossible. Under the HAVEN Act, service on a qualifying vessel during the covered period is enough.
The HAVEN Act's provisions became effective January 1, 2020. Veterans who filed new claims or had pending claims after this date could qualify under the new rules. Veterans who were previously denied solely due to Blue Water status can file a Supplemental Claim to have their claim reconsidered under the new standard.
The VA maintains the "Ship List" — a database of vessels whose service records indicate they operated in qualifying Vietnam-era waters. The list is searchable on VA.gov by ship name. As of 2026, the list includes hundreds of vessels across ship types.
The HAVEN Act covers service in the territorial seas of the Republic of Vietnam — defined as waters within 12 nautical miles of the Vietnamese coastline. Service in these waters at any time between January 9, 1962 and May 7, 1975 qualifies.
The list includes, but is not limited to:
If your ship is not on the VA's Ship List, you are not automatically disqualified. You can submit evidence of your ship's presence in qualifying waters — including deck logs, ship movement orders, logbooks, or other official records. The VA can add ships to the list based on evidence. Work with a VSO or attorney to gather this documentation.
Blue Water Navy veterans who served on qualifying vessels are now presumed to have been exposed to Agent Orange and are entitled to service connection for any of the following conditions, provided the condition is at least 10% disabling:
Additionally, veterans may also be eligible under the PACT Act (2022) for additional toxic exposure-related conditions depending on their specific deployment history.
Proving qualifying Blue Water service requires showing that your ship was in Vietnamese territorial waters during the covered period. Here's how:
Check VA.gov's Blue Water Navy Ship List. If your vessel is listed with dates that overlap your service, you may not need to submit additional service location documentation — the VA accepts the ship list as presumptive evidence of exposure.
If you were previously denied for an Agent Orange-related condition because the VA determined you were a Blue Water Navy veteran and didn't qualify, you can file a Supplemental Claim to have your case reconsidered under the HAVEN Act's new rules.
