Deck Logs and Naval Records

Naval deck logs are official daily records maintained by ships of the United States Navy. These records document a vessel’s operations, movements, and activities, including navigation entries that record the ship’s position and operational status.

For veterans who served aboard naval vessels during the Vietnam War and other periods of military service, deck logs can provide important historical documentation related to where ships operated during specific timeframes.

These records are preserved by the U.S. National Archives and Records Administration and serve as official historical documentation of naval operations.

What Deck Logs Record

Deck logs are maintained by the ship’s officers and typically include information such as:

  • Ship location and navigation coordinates
  • Course and speed
  • Operational activities
  • Anchoring or port entries
  • Significant events occurring aboard the vessel

Why Deck Logs Matter for Veterans

For some veterans, particularly those who served aboard ships operating near coastlines or within territorial waters, deck logs can help establish

where a vessel was located during a specific period of service.

Ship location data may help determine whether a vessel operated within areas that are relevant to toxic exposure claims or eligibility for certain benefits under federal law.

Historical naval records can therefore play an important role when researching service history and operational environments.

Deck Log Research and Analysis

Military-Veterans Advocacy works with researchers who analyze historical naval records, including deck logs and ship operational documentation.

Researchers affiliated with the organization review these records to better understand where naval vessels operated during specific periods of military service. This research helps support ongoing efforts related to toxic exposure policy, litigation, and veteran education.

Requesting Deck Logs

Deck logs from U.S. Navy vessels are archived and maintained by the National Archives and Records Administration, and veterans and researchers
may request them directly through the National Archives.

Requests may require specific information such as: Ship Name, Date Range of Service & Approximate Operational Timeframe

Deck Log Research Assistance

Military-Veterans Advocacy may be able to provide limited guidance identifying relevant deck log records for certain ships and time periods.

This assistance depends on the availability of volunteer researchers and historical records.

Veterans who have questions about deck logs or naval records related to their service are encouraged to contact Military-Veterans Advocacy for additional guidance.
