These pages describe a Space War game that allows two players to control spaceships in a star's gravity well, shooting missiles at each other, and dropping mines in each others' paths.  The player with the last remaining ship wins.  The game is written to take advantage of Java objects and classes, and makes use of a number of design patterns.  This report describes the game's design and implementation, and compares this implementation to an earlier version of this game written in PDP-12 assembly language.
