Impact of GFO Satellite and Ocean Nowcast/Forecast Systems on Naval Antisubmarine Warfare (ASW)

Abstract

The purpose of this thesis is to investigate the value-added of the Navy's nowcast/forecast and GFO satellite to the naval antisubmarine warfare (ASW) and anti-surface warfare. For the former, the nowcast/forecast versus observational fields were used by the 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 anti-surface warfare scenarios and three ASW scenarios, in each of two regions: the East China Sea and South China Sea. Analysis of the output reveals that POM outperforms MODAS in all tactic scenarios. For the latter, the MODAS (T, S) profiles were used by the WAPP to determine suggested presets for Mk 48 variant torpedo. The only difference in the MODAS fields was the altimeter used to initialize the respective MODAS fields. The same metrics used in the nowcast/forecast case were used to generate and compare the acoustic coverages. Analysis of the output reveals that, in most situations, WAPP output is not very sensitive to the difference in altimeter orbit.
