USS Apache (ATF 67)
The Integral Operating Unit underway during a tow to a dive site. Apache was permanently assigned to provide mobility to White Sands (ARD 20) in which the bathyscaph Trieste was embarked. Once at the dive site Apache would cast off the tow line and White Sands would operate independently in support of Trieste.

A typical World War II ARD
This World War II view of an unidentified ARD shows the inside of the dock with the most distinctive feature of the ARD, a closed bow with a bridge on top. A crane ran on rails on each sidewall. The ARD 2 class was designed to dock destroyers and submarines, and the ARD 12 class had the same 3,500-ton lift capacity but was broadened ten feet to accommodate LSTs as well.
