This patent application discloses a submarine mast simulator as part of a buoyant tow body having a hydrodynamically shaped shell. The mast simulator includes a rigid lower mast section and an inflatable upper mast section extendable from the tow body. A plurality of stabilizer fins extend radially from the tail of the tow body, the fins being actuated to cause the ascent and descent of the tow body. A pressure sensor is positioned on an outer surface of the tow body for detecting the depth of the tow body, and a motor with controller is housed within the tow body. The controller initiates the extension of the mast simulator in response to a depth indication. The overall purpose of this invention is to provide a submarine mast simulator for antisubmarine warfare training. This invention does the following: simulates the visual appearance, radar footprint, infrared/chemical emissions, and wake generation characteristics of a submarine mast protruding above a water surface; is easy to launch and recover; is towable by an unmanned underwater vehicle; and is inexpensive to manufacture.
