Joint Communication Simulation System provides communications planners and system analysts with the capability to validate support plans, analyze existing and proposed network architectures and evaluate the performance of new devices and applications.

Provide an integrated ability to analyze communication networks while also providing a validated simulation capability with databases and underlying models so that studies can be consistent throughout the Unified Combatant Commands, Services, and others within the Command, Control, Communications, and Computer Systems (C4) community.

By simulating communications effects of existing or planned networks that support warfighter operations, JCSS helps to quantify risks and identify C4 deficiencies prior to execution or change implementation. Results from JCSS simulations and analyses also provide support for prudent acquisition decisions.
