A submarine warfare radar training system 10 includes an underwater vehicle 15 towing a float device 40 and a radar reflective target 45. The radar reflective target 45 is configured as a hollow tube-shaped element 50 having circular open leading and trailing open circular ends to allow water to flow through the target as it is towed. The target 45 includes a positive buoyancy material layer 60 and is horizontally oriented during towing. The float device 40 is configured to support the radar reflective target 45 open leading end above the water surface 30 as the float device 40 and radar reflective target 45 are towed along the water surface to deliver air into the hollow cross-section. The radar reflective target 45 has an adjustable RCS which can be increased or decreased by lengthening or shortening the radar reflective target.
