Airborne Rapidly Deployable Technology (ARDT) is being investigated by the US Navy. One of the areas crucial for the project's a success is an in-water deployment of an array. In a recent trial, instrumented arrays were deployed from a moving ship and allowed to descend to the bottom. The purpose of this trial was to demonstrate an ability to deploy a long array of sensors in this manner such that the array has a stable descent and regular element spacing on the bottom. An analysis of the results obtained from that trial is presented. Two arrays were successfully deployed. The depth histories of various points along the array and the location of the array on the bottom were obtained for each deployment. The results indicated that the arrays achieved stable descent rates and were placed on the bottom with regular element spacing. The SEADYN cable dynamics model was used both to design the arrays before the trial and to attempt to replicate the trial results. It was successful in both tasks. The experiment and subsequent analysis indicated that arrays can be designed to descend through the water column to the bottom in a stable and predictable manner after being deployed from a moving platform.
