High Efficiency Mission Performance for Underwater Expendable Countermeasure Devices Commonality Applications

Integrated electronics, control, and navigation/propulsion modifications will be investigated to provide 40% improved efficiency for ADC Mk II operations. Leveraging its UUV-development expertise, Nekton will focus on: 1) design of a linear navigationalcontrol system to replace existing solenoids, 2) design deployable, recessed, mid-body fins for lift enabling efficient high speed level navigation, and 3) design of FPGA/DSP-based electronics to significantly reduce electronics power and spacerequirements, which will free-up space for a shallow recess in the outer hull surface to accommodate deployable fins. Phase II will yield a prototype for field tests. ANTICIPATIED BENEFITS: The proposed effort will significantly improve the range and velocity of the Mk II, initial estimates exceed 40%, while also improving its control and eliminating the characteristic (detectable) swimming pattern now employed toaccommodate negative buoyancy and lack of lift. Following the Phase I specification and initial design, Phase II will complete design and yield a prototype incorporating the specified enhancements. In addition to providing a low cost reliable solution tothe identified deficiency of the Mk II, the proposed effort also addresses technology issues in anticipation of Next Generation Countermeasures development.COMMERCIAL APPLICATIONS: The components developed under this effort are optimized for the military mission but the subassemblies clearly are applicable in UUVs for environmental monitoring or research, as well as tactical oceanography, minecountermeasures, and plume mapping or other toxicant detection missions.
