Ship Logs
On August 9, 2019, VA signed an agreement with the
National Archives and Records Administration allowing
VA to take the deck logs of U.S. Navy and Coast Guard
ships from the Vietnam era (1956-1978) offsite and digitize
them. VA anticipates all deck logs will be scanned by
January 1, 2020, in time for P.L. 116-23’s implementation.
The deck logs include the ships’ movements, locations,
activities, and, sometimes, personnel issues. By scanning
these logs and using documented coordinates, VA can
create tools to identify whether a veteran was within the 12-
nautical-mile region. This will assist BWN veterans in their
claims, as a veteran will only need to provide a ship name
and dates of service on the ship, not specific coordinates.
Outreach to Veterans
P.L. 116-23 requires VA to implement an outreach program
to inform veterans who qualify under the new law that they
have the opportunity to submit a disability compensation
claim. This outreach includes publishing the information on
the VA website and sending written notification to veterans
and veteran service organizations (VSOs) of the submission
or resubmission process.
