I would like to take this opportunity to tell some of the tasks that the AT A 192, later named USS Tillamook and crew were called on to do before and after each of the A bomb tests. Other tugs did similar tasks
The first USS Sunnadin (AT-28), a tug, was laid down on 3 December 1918 at the Puget Sound Navy Yard as Katahdin; renamed Sunnadin on 24 February 1919; launched on 28 February 1919; and commissioned on 20 October 1919.
