The U.S. Navy is a major investor in ocean model development. The pay-off of such an investment is the value-added ocean nowcastforecast systems on the naval operations and warfare effectiveness. The purpose of this paper is to investigate the value-added of the Navy s nowcastforecast system to the naval antisubmarine warfare ASW and anti-surface warfare ASUW. The nowcastforecast versus observational fields were used by the Weapon Acoustic Preset Program WAPP to determine the suggested presets for Mk 48 variant torpedo. The metric used to compare the two sets of outputs is the relative difference in acoustic coverage area generated by WAPP. Output presets are created for five different scenarios, two ASUW scenarios and three ASW scenarios in the South China Sea. The same metrics used in the nowcastforecast case were used to generate and compare the acoustic coverage. Analysis of the output reveals that the ocean forecast system outperformed the nowcast system in most scenarios.
