An integrable naval virtual target range system and method provides three-dimensional graphical viewing capabilities of a virtual target range so that naval and fire support personnel can train together during both simulated and live fire exercises. The virtual target range system comprises a control subsystem having a computer system and a spotter subsystem for monitoring virtual impact points on the virtual target range. The target system may further comprise a buoy subsystem and/or an aerial vehicle subsystem, for use during live fire exercises, to locate ordnance impact points used for calculating the virtual impact points.
