Today there is increased military, commercial, and scientific interest in the use of deeper diving vehicles to explore, exploit, and transport at deep ocean depths. Stronger and more weight-efficient materials and structures are required for the pressure hulls of these vehicles. This paper discusses the balance between design-materials-fabricability and experimental verification. The various types of scaled model tests used to provide the required experimental verification are described. Model test results are compared with analytical predictions and full-scale prototype behavior. Submarine hull concepts and materials that may be necessary in the not-too-distant future are described. New concepts of simple specimen design and testing which may be required prior to utilization in model tests are also discussed.
