Change Log

    • Alternative module 1.3 offers another different implementation of this great game! I will add some setups via an extension when I'm sure no changes will be required in the module. There is a "How to Use the VASSAL module" video in the help menu. I updated the IJN to better reflect the rules, automated the sunk ships tally and tonnage.


Silent War is a solitaire simulation of the United States' Navy submarine war against Imperial Japan in World War Two. You serve as Commander of Submarines, US Pacific Fleet (ComSubPac). Your mission is to deploy your boats with maximum effect to destroy Japanese shipping, while limiting your own submarine losses.

Note: Only the first 4 Campaigns are completed in the module. More to come.
