BLUFTowed Targets can inexpensively emulate airborne threatsTMO has a “basket” of various towed targetsPerformance envelope very similar to drone or aircrafttowed from (except Gs)Less Costly Acquisition & Tracking TestingLess Costly Live-Fire Testing/Training (typically 1/25th cost of towing drone)TMO has in-house/ and contract capability to design/fab protoTtype towed targets to meet customer testing requirements.MO22 October 2009PM-ITTS
