Recently, as underwater weapons in underwater warfare such as torpedoes, decoys and submarines have been more diverse and complicated the factors of risk in underwater warfare system development increase. In order to determine requirements for underwater warfare systems, and to design and evaluate those systems, various modeling and simulation (M&S) techniques have been used for underwater warfare. In past years, there have been some efforts to develop the underwater warfare simulation for academic purpose as well as commercial tools. ODIN and ORBIS are simulation tools for underwater warfare developed for commercial. Because these tools are not based on the mathematical representations such as the Discrete Event Systems Specifications (DEVS) formalism, it brings modelers difficulty to extend their own developed models. For academic purpose, there has been a research about the simulation of a submarine’s evasion against a torpedo in

2007. In this research, all of the simulation models are developed using DEVS formalism, but if the user would like to evaluate the alternative evasion tactic of the submarine, the user should develop another DEVS model. It is a disadvantage for modelers in an aspect of model reusability. This paper proposes the DEVS based underwater warfare simulation development for Effectiveness Analysis. The proposed simulation development provides to simulate with the overall engagement scenario, for example from underwater weapon launch to hit. It is designed to support for users to evaluate effectiveness of underwater warfare systems through Monte Carlo simulation and to assess tactical development and anti-torpedo countermeasure effectiveness.
