Simian is an agent based legacy simulator developed in Java used to develop scenarios involving unmanned air vehicles. The goal of this paper is to host the Simian simulator on a C# platform and also to extend the currently existing functionality using C# by adding more behaviors to the UAVs. The Java code is converted into C# code in order to run the simulator on a visual studio framework, but the structure and interfaces defined in the Java version have been retained in the new framework. The scenarios added to the UAV include: 1. the ability to exhibit a swarm type behavior while performing a sweep search, 2. to detect a target in the hostile environment and rotate over the target, and 3. to search through the hostile environment and destroy a target when detected. All the behaviors have been demonstrated using multiple scenarios in the Simian simulator.
