1.5 times the maximum depth rating, minimization of air-backed implodable volume, and manufacturing to ensure no separation of parts from the main unit in the event of shock, are paramount. The minimum expected depth for the sensor will be 3,000 m. The sensor can be mounted as either upward- or downward-looking. Therefore, the transducer faces should be ruggedized to protect from abrasion by having a shore durometer of at least 90A or a final coating of the same hardness of sufficient thickness to protect transducer faces. The ADCP/DVL head that is exposed to ocean flow should have minimal impact on hydrodynamic flow by having a baffled drag coefficient less than half that of a hemisphere of the same diameter as the ADCP/DVL head. The exposed ADCP/DVL head should have minimal or no cavities and features that would produce structure borne (aside from intended transduced acoustics), airborne and fluid borne noise per NAVSEA S9070-AA-MME-010/SSN/SSBN, (3.15).

 

The Navy desires innovative ADCPs and DVLs that can be deployed from existing U.S. Submarine Classes in a tactical environment to provide real-time measurements of speed through water, speed over ground, and speed and direction of ocean current strata. Proposed designs should be able to meet the following goals: shock grade A requirements; and submergence, power and attachment capability to meet current tactical submarine alteration requirements per NAVSEA S9070-AA-MME-010/SSN/SSBN. ADCP and DVLs that satisfy requirements for tactical installations will allow unrestricted transits during scientific or tactical missions, thus providing greater flexibility for a submarine to operate in its intended environments without having to stop a mission to remove a non- tactical piece of equipment.

 

The Phase II effort will likely require secure access, and NAVSEA will process the DD254 to support the contractor for personnel and facility certification for secure access. The Phase I effort will not require access to classified information. If need be, data of the same level of complexity as secured data will be provided to support Phase I work.

 

Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. Owned and Operated with no Foreign Influence as defined by DoD 5220.22-M, National Industrial Security Program Operating Manual, unless acceptable mitigating procedures can and have been be implemented and approved by the Defense Security Service (DSS). The selected contractor and/or subcontractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances, in order to perform on advanced phases of this contract as set forth by DSS and NAVSEA in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material IAW DoD 5220.22-M during the advance phases of this contract.

 

PHASE I: Develop a concept for real-time ADCPs and DVLs that can be deployed on existing U.S. Submarine Classes. Demonstrate the feasibility of the concept in meeting Navy needs and establish that the concept can be developed into a useful product for the Navy. Establish feasibility by material testing and analytical modeling. Evaluate the concept by determining how well they address the ADCP/DVL goals and how they will demonstrate feasibility through a financial and marketing analysis that must be submitted with all concept ideas. Provide a Phase II initial proposal with performance goals, key technical milestones, and technical risk reduction. The Phase I Option, if exercised, will include the initial design and capabilities description to build the unit in Phase II.

 

PHASE II: Develop a prototype for evaluation by the Government to determine its capability in meeting the performance goals defined in Phase II SOW and the Navy requirements. Demonstrate system performance through prototype testing over the required range of parameters, including numerous deployment cycles. Use test results to refine the prototype into an initial design that will meet Navy requirements. Prepare a Phase III development plan to transition the technology to Navy use. Support the Navy for test and validation to certify and qualify the system for Navy use on existing U.S. Submarine Classes.

 

It is probable that the work under this effort will be classified under Phase II (see Description section for details).

 

PHASE III DUAL USE APPLICATIONS: Support the Navy in transitioning the ADCP/DVL technology for Navy use. Develop ADCPs and DVLs that are deployable from the hull of a submarine for evaluation to determine their effectiveness in an operationally relevant environment.

 

Commercial and dual use applications include every major marine industry, surface and submarine. ADCP/DVL
