The concept of a new test facility to evaluate the underwater launch and flight performance of full-scale missiles and associated launcher systems is described. Results from preliminary studies on estimates of the platform dimensions hydrodynamic characteristics, and platform response to a missile launch impulse are included. The VSAERO panel method code was used to generate hydrodynamic force and moment coefficients for the condition of steady tow at 5 knots. These coefficients were then used to evaluate the platform trim stability under steady tow conditions. Calculations indicate that the platform is stable during all three phases of operation: missile in tube, empty tube, and tube fully flooded. Preliminary estimates of the platform response due to a launch impulse show a recoil that is not expected to significantly alter the fidelity of the in-tube trajectory data.
