Abstract : Project 3.9 was primarily concerned with modifying and outfitting three barges 260 ft in length by 50-ft beam (YFNB 12, 13, and 29) to serve as surface control stations for submersible targets and as support vessels for remote recording instrumentation. The project was developed and concluded in two phases: the first phase consisted of major structural modifications and outfitting, ending at initial sea trial of each individual barge; and the final phase included minor modifications and additional changes to meet operational requirements, terminating at the January sea trial, at which time the barges were considered to be adequate for the final task. The barges performed their intended function in the Wigwam array and proved adequate as target control stations and floating bases for instrumentation. During the rather rough sea conditions encountered, the YFNB's were sufficiently stable to remain as effective elements in the array, permitting uninterrupted helicopter service from their landing platforms at times when difficulty was experienced with other array components. Based on this experience, it is recommended that no element smaller than a 100-ft YC barge be used in a Wigwam type array during tests to be conducted on the open sea. (Author)
