USS Ranger (CVA-61) The Deck Logs Project was undertaken by members of the original Blue Water Navy Vietnam Veterans Association to document when certain ships were within Vietnam Territorial Seas defined as 12 miles from Baseline. The Vietnam War Era covered by the analysis is January 1962 through May 1975. This document represents data taken from the SECNAV 1650 Report which alleges to provide all dates a naval unit qualifies for a medal or ribbon. In this case, these are the dates when a ship's crew was eligible for the Vietnam Service Medal or an alternative Armed Forces Expeditionary Medal, indicating they were in the Vietnam Theater of Combat during the time period shown. The image below is a bar chart indicating the location of the ship during the Vietnam War. It shows that the ship was either in or not in the Theater of Combat and when the ship was in the Territorial Seas of Vietnam. In the Bar Graph, the Yellow cells indicate when the ship was anywhere except in the Theater of Combat. Gray bars in the graph below represent every month when the ship was in the Theater of Combat, and Red bars represent a month when the ship was inside the 12 miles from the Baseline limit of the Vietnam Territorial Seas for some portion of at least one day during that specific month. The following pages provide details on the ship's positions inside the Territorial Seas (the Red portions of the above graph).

USS Ranger (CVA-61)The Deck Logs Project was undertaken by members of the original Blue Water Navy Vietnam Veterans Association to document when certain ships were within Vietnam Territorial Seas defined as 12 miles from Baseline. The Vietnam War Era covered by the analysis is January 1962 through May 1975.

This document represents data taken from the SECNAV 1650 Report which alleges to provide all dates a naval unit qualifies for a medal or ribbon. In this case, these are the dates when a ship's crew was eligible for the Vietnam Service Medal or an alternative Armed Forces Expeditionary Medal, indicating they were in the Vietnam Theater of Combat during the time period shown.

The image below is a bar chart indicating the location of the ship during the Vietnam War. It shows that the ship was either in or not in the Theater of Combat and when the ship was in the Territorial Seas of Vietnam.

In the Bar Graph, the Yellow cells indicate when the ship was anywhere except in the Theater of Combat. Gray bars in the graph below represent every month when the ship was in the Theater of Combat, and Red bars represent a month when the ship was inside the 12 miles from the Baseline limit of the Vietnam Territorial Seas for some portion of at least one day during that specific month.

The following pages provide details on the ship's positions inside the Territorial Seas (the Red portions of the above graph).

N.B.: Here is an example of a problem a Deck Log reader can be presented with. When analyzing the Deck Log for 25 April 1966, we find that, based on the longitude and latitude entries for the 0800, 1200 and 2000 hours, RANGER appears to have traveled more than 480 miles round trip to the western side of the Mekong Delta and back. But that would have required a minimum constant speed of 60 mph (beyond flank speed) with no stopping at the far side destination. So the Longitudinal entry at 1200 hours is certainly in error. Proposing a change, a longitudinal distance between 107.28 and 107.19 (roughly 5 miles in 4 hours) would be reasonable. Alternatively, a Latitudinal distance change between 08.5N and 09.2N and back (roughly 42 miles) at the same longitude is also reasonable. But since we don’t know which of these scenarios might be true, we need to ‘throw out’ the 1200 hours location entry. This type of error occurs more frequently than one would like, and a judgment call like this is always necessary. But in this instance, crew members will get credit for being in the Territorial Seas for that day based on the other readings, so a precise 1200 hours entry is not important.
