The CH-53K King Stallion helicopter program intends to design, develop, and maintain the platform using three-dimensional 3D models documented in CATIA computer-aided design CAD software. The programs planned approach for delivering 3D technical data as CAD modelsfiles to support system sustainment presents a challenge for the Naval Supply Systems Command NAVSUP and the Defense Logistics Agency DLA because their current provisioning and cataloging processes are built to accommodate and use two dimensional technical data, not 3D models. CH-53K 3D model issues relative to supporting the provisioning and cataloging processes are not unique. A number of Navy and other developing Department of Defense DoD weapon system programs plan to use 3D models as part of a model-based enterprise approach throughout the systems life cycle. Unfortunately, guidance regarding 3D data completeness and format requirements is lacking. NAVSUP, DLA, and the CH53K program have identified a solution for the 3D technical data challenge that may become the benchmark for addressing similar challenges with other DoD weapon system acquisition programs. Specifically, they found that the 3D PDF file format is the best solution for providing CH53K 3D technical data to support provisioning, cataloging, and sustainment.
