Abstract
The U.S. Navy is a major investor in ocean model development. The pay-off of such an
investment is the value-added ocean nowcast/forecast systems on naval operations and
warfare effectiveness. The purpose of this paper is to investigate the value added of the
Navy’s nowcast/forecast system to naval antisubmarine warfare (ASW) and anti-surface
warfare (ASUW). The nowcast/forecast 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 nowcast/forecast 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.
