What component replaces the rocket motor and hydraulic actuation system on the training missile TGM-65?

The component that replaces the rocket motor and hydraulic actuation system on the training missile TGM-65 is a film recorder or ballast. This substitution is made to ensure that the training variant of the missile mimics the weight and balance of the operational missile while not being designed for actual flight capabilities. The film recorder serves to capture data during training exercises, enabling analysis of performance and guidance systems without the propulsion and hydraulic systems present in active missile versions. This provides a realistic training environment without the risks associated with live fire operations. The use of ballast also helps to simulate the mass distribution and aerodynamic characteristics of the operational missile, which is critical for realistic training scenarios.
