The Phase I study developed a prototype design for integrating a propulsion capability with guidance and control onto a standard 3 inch submarine torpedo countermeasure. An inexpensive design based on engineering change integration into a production ADC MK2 MOD1 was developed that will achieve the 20 Knot speed for 3 minute duration requirement of SBIR Topic N94-207. The design provides propulsion through the addition of a DC motor while retaining major subsystem (i.e. acoustic projector, power source, etc.) of the SDC within the existing production size. The Phase II effort is planned for an Initial Phase followed by an Option Phase. The Initial Phase will focus on completion of the prototype design, fabrication, and test and evaluation of three prototypes. Testing will validate and demonstrate integration of the subassemblies as well as the capability to transit at 20 knots. The Option Phase will be for follow on development and test and evaluation to demonstrate speed and endurance performance parameters as well as performance capabilities such as launch survivability, guidance and control, hover, and acoustic operations. Phase II is expected to achieve full readiness for initial rate production based on an engineering change product integration. Production is planned for Phase III.
