After work on "UB-5" was complete at the Germaniwerft yard, "UB-5" was readied for rail shipment. The process of shipping a UB I boat involved breaking the submarine down into what was essentially a knock down kit. Each boat was broken into approximately fifteen pieces and loaded onto eight railway flatcars. In early 1915, the sections of "UB-5" were shipped to Antwerp for assembly in what was typically a two- to three-week process. After "UB-5" was assembled and launched sometime in March, she was loaded on a barge and taken through canals to Bruges where she underwent trials.
