Simulated Ship Shock Tests/Trials?
Abstract:
Submarine Shock Tests and surface ship Shock Trials are vital components of ship test and evaluation (T&E), and of Live Fire Test and Evaluation (LFT&E) requirements. Ship Shock Tests/Trials, surrogate and component tests, the Total Ship Survivability Trial (TSST), and associated analyses and simulations are key components of any alternative to full-up, system-level testing using munitions likely to be encountered in combat. Ship Shock Tests/Trials, although conducted under conditions more benign than realistic threat conditions, provide insight into platform vulnerabilities with respect to underwater proximity bursts, and produce significant decision-making data for corrective actions. The cost of conducting a ship Shock Test/Trial and the tremendous advances in simulation capabilities are driving the question: "Can simulations be substituted for ship Shock Tests/Trials? " Unfortunately, current simulation capabilities still seem insufficient to provide decision-making data of equal utility to ship Shock Tests/Trials. Simulations hold the potential, however, to provide complementary decision-making data of greater value than ship Shock Tests/Trials alone. Simulation capabilities must therefore continue to be advanced. This paper contrasts the relative, overall utilities of ship Shock Tests/Trials and simulations. A list of advantages for both tests and simulations is presented, with strong arguments in favor of a combination of both approaches.
