For effective operation of naval warfare simulation system, build the date frame of naval warfare simulation scenario. Paper described the W5 principle of scenario, and analyzed the need of building the scenario date frame; classified the elements of simulation scenarios around the scenarios describe W5 principles, built the date frame of naval warfare simulation; extracted and designed each part of the frame and used the XML language to realize the description of the naval warfare simulation scenario. Application results show that the framework can provides all kinds of naval warfare simulation scenarios with rapid data support.
