The USS Tattnal DDG19 is a Charles F Adams Class Guided Missile Destroyer. Robert MacNamara served on the Tattnal in the mid-60s.
The multi-media kit he used to replicate it is the USS Barney by Iron Shipwrights which was the 1985 configuration.
Robert back-dated it to show how it looked when he served on it. He did extensive scratch building to retro-fit it.
The Tattnal was built at Avondale Shipyards in Avondale Louisiana in 1960.
