KEYWORDS: Electronic Warfare Systems Human Machine Interface; Situation Awareness; Game Theory and modeling; Statistical Analysis, Intuitive Operator Interaction, Signal Analysis N151-037 TITLE: Fat Line Tow Cable TECHNOLOGY AREAS: Sensors, Electronics, Battlespace ACQUISITION PROGRAM: PMS401 Submarine Acoustic Systems Program Office OBJECTIVE: Develop a submarine TB-16 Fat Line Array medium weight tow cable that uses the existing coaxial core that improve compressional ruggedness with modest-weight penalty, when compared to the existing TB-16 lightweight tow cable. DESCRIPTION: The Navy seeks innovative strength member construction techniques for the TB-16 Fat Line Array tow cable that significantly improves axial compression and cut resistance. Since current lightweight materials in use today are unable to provide the needed compressional strength or resistance to external damage by fish hooks, new materials or application of existing materials for the solution will be needed to meet requirements. Currently available tow cables are either lightweight or heavyweight; there is no available material or construction technique which combines the best properties of each. It is recognized that available lightweight materials (such as Vectran, Zylon) require reinforcement that increases cable density, but the goal is to minimize the impact. The proposed solutions should retain existing coaxial core, and a modest weight increase is permissible. A modest weight penalty relative to standard lightweight construction will still provide good depth separation between two towed arrays while minimizing the strum energy imparted onto the system. The proposed Fat Line Array tow cable shall be capable of withstanding 220 pounds of axially applied compressional loads that are imparted by the OK-276 fat line handling system, as well as being terminated within the diameter of the tow cable nose cone (3.35 inches). The new tow cable may have a 30% weight increase (as compared to existing light weight TB-16 tow cable) to allow for a more rugged tow cable, with the goal of withstanding axial compressional loads. These loads will be measured on the NAVY’s land-based SSN OK-276 handling system located at NUWCDIVNPT in Newport RI. (Ref 1, 2 and 3). Additionally, the High Density Polyethylene (HPDE) currently used as a jacket material is easily cut by items such as fish hooks. Axial stiffness solutions that include making the cable more cut-resistant are greatly desired. PHASE I: The small business will develop concepts that demonstrate substantially improved axial compressional resistance for the tow cable variant while providing a range of densities. Options should describe expected cut resistance improvements over the current HDPE. Each identified option should have a supporting simulation/calculation, showing relevant depth trail characteristics (towed array depth relative to tow platform over a range of speed and scope combinations). The small business will demonstrate the feasibility of the concepts in meeting Navy needs and will establish that the concepts can be feasibly developed into a useful product for the Navy. Feasibility will be established by material testing and analytical modeling. PHASE II: Based on the results of Phase I and the Phase II contract statement of work, the small business will develop a prototype(s) for evaluation as appropriate. The prototype will be evaluated to determine its capability in meeting the performance goals identified above and the Navy requirements for Fat Line Array coaxial tow cables, such as survivability of 150 reeling cycles on the OK-276 handler with the dynamic seal in place These cables will be compliant with push-force requirement of 220 lbs. The Fat Line Array tow cable will be evaluated at both the raw cable level as well as the terminated cable level on the OK-276 LBTF and assessed for repeated handling cycles as well as compressional resistance. Modeling or analytical methods over the required range of parameters including numerous deployment cycles, tension and towing characteristics shall be performed. Evaluation results will be used to refine the prototype into a design that will meet Navy requirements and will be evaluated during a tow test while connected to a TB-16 Fat Line Array at Lake Pend Oreille, Idaho where Navy tow testing is performed. If successful, the small business will prepare a Phase III development plan to transition the technology to Navy use. PHASE III: If the Phase II prototype is successful, the small business will be expected to support the Navy and array manufacturers in transitioning the new cable design into existing systems for Navy use. The small business will finalize the design of a tow cable for evaluation to determine its effectiveness in an operationally relevant environment. The small business will support the Navy for test and validation to certify and qualify the system for Navy use. PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: A medium-weight tow cable is applicable to surface Navy towed array programs. Additionally, oil and seismic exploration arrays could benefit from the innovative construction technique to better control the depth towing profile for varying geographic locations. REFERENCES: 1.

Offerors must disclose any proposed use of foreign nationals (FNs), their country(ies) of origin, the type of visa or work permit possessed, and the statement of work (SOW) tasks intended for accomplishment by the FN(s) in accordance with section 5.4.c.(8) of the solicitation. Offerors are advised foreign nationals proposed to perform on this topic may be restricted due to the technical data under US Export Control Laws. OBJECTIVE: Develop an innovative approach to collect meteorological data for deep-diving submergible vessels in real time. DESCRIPTION: The Navy is developing tools requiring access to meteorological data, such as humidity, wind, and temperature, for use aboard submergible vessels (1,4). Currently, a naval vessel can receive weather reports which may contain inaccurate or untimely data (2,3). Weather has a significant impact on undersea vehicle mission execution. Outside of its impact on navigation, weather is an umbrella term for a set of parameters that defines the atmospheric medium in which electromagnetic signals pass, be it radar signals, satellite signals, communication signals, and imaging signals, all of which are functions that are required within the mission space of an undersea vehicle. Undersea vehicles, either unmanned or submarines, currently have extremely limited ability to collect meteorological parameters. The capability proposed would be part of a command tool that would improve targeting, command and control of mission payloads, and situational awareness. The Navy desires an innovative approach to obtain the following weather information in real time – humidity, wind speed and direction, atmospheric pressure, and sea/air temperature. Any sensors used would have to be survivable on a deep-diving vessel (and the inside of the submarine sail is free flooding), although data could be collected on the surface. Current state of the art sensors are not able to survive deep submergence. The solution could be a new survivable sensor, but making use of existing radar, antenna, or imaging systems has appeal as an approach as these systems do not require new components. In addition, disposable buoys, which make use of the existing ability to launch expendable three inch diameter buoys, would be an acceptable solution if cost effective. (less than $3,000 per unit in mass quantity). The challenge for submarine-mounted meteorological sensors is to find a way for the sensors to survive the rigorous environment of submarines if left to the elements, and then be able to operate when exposed above the water's surface. The physics of meteorological sensors is predicated on the sensors being dry. Therefore, a way to keep the sensors dry or to have them quickly dry is paramount. Furthermore, the desired sets of meteorological parameters are not just localized to the near field (within a few feet), but also far field (i.e. out several miles). It would also be advantageous to vertically sample the atmosphere to locate and identify changes in atmospheric turbulence and properties over the viewable distance, which can impact electronic warfare operations and radar signals. The solution should be able to measure humidity, wind speed and direction, atmospheric pressure, and sea/air temperature in real time with an accuracy similar to state of the art land based sensors, can make use of existing sensor and launch systems if appropriate, and must cost under $3000 in mass quantity of a disposable sensor. 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. The Phase II effort will likely require secure access, and NAVSEA will support the contractor for personnel and facility certification for secure access. PHASE I: The Company will develop a concept for meteorological data collection aboard submergible vessels that meets the requirements described in the description section. The company will demonstrate the feasibility of the concept in meeting Navy needs and will establish that the concept can be feasibly developed into a useful product for the Navy. Feasibility will be established by testing and/or analytical modeling. PHASE II: Based on the results of Phase I and the Phase II contract statement of work, the company will develop a prototype for evaluation. The prototype will be evaluated to determine its capability in meteorological data collection with similar accuracy for the parameters listed in the description. Performance will be demonstrated through prototype evaluation and modeling or analytical methods. The exact method of testing will vary depending on the design provided, but would include integration with land based submarine system test facilities if the design utilized these systems, testing with a land based three inch launcher (if appropriate) or localized in-water testing. Evaluation results will be used to refine the prototype into a design that will meet Navy requirements. The company will prepare a Phase III development plan to transition the technology to Navy use. PHASE III: The Company will be expected to support the Navy in transitioning the Submarine Meteorological Sensor technology for Navy use. The company will develop the sensor in accordance with the Phase III development plan for evaluation to determine its effectiveness in an operationally relevant environment. The company will support the Navy for test and validation to certify and qualify the system for Navy use. PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: Approaches to atmospheric data collection will be applicable to all seaborne vessels and remote or unmanned vessels operating in ocean environments.

OBJECTIVE: Develop a multiple-beam electron gun with permanent magnet focusing for a broadband, millimeter-wave amplifier with reduced size, weight, and power requirements. DESCRIPTION: The Navy requires high-power, low-volume, reduced-weight, efficient and affordable millimeter-wave amplifiers for Electronic Warfare (EW) systems. The requirement for high power in a small, lightweight package is acute in some cases. Vacuum electronic devices have demonstrated the ability to deliver single-device powers in excess of projected solid-state amplifier powers, particularly at millimeter-wave frequencies. Millimeter-Wave (MMW) amplifiers are the key component in future transmitters used for electronic attack, high-data-rate communications, and radar. New and next-generation MMW transmitters must operate at higher frequencies and generate significantly higher RF power per unit mass than has been achieved today. The Navy needs innovative devices to provide mission-critical capabilities such as improved self-protection against emerging anti-ship missile threats, increased operating range, high communications data rates, and all-weather operation for diverse platforms (including small autonomous platforms). The Navy seeks an enabling technology for a new class of affordable, miniature, high-power MMW amplifiers suitable for multi-platform applications. This technology will ultimately increase MMW amplifier specific power density (defined as RF output power per unit size or weight) by more than a factor of five over the current state-of-the-art. Vacuum electronic (VE) slow-wave amplifiers have a demonstrated ability to deliver single-device power well in excess of existing or projected solid-state amplifier power in the MMW range, with higher efficiency because of residual energy recovery by depressed electron beam collectors. High output power and low total power consumption make VE amplifiers very attractive for new systems. However, the most recent advances in the power and bandwidth of VE amplifiers have been for devices operating at moderate-to-high voltages (typically, above 15 kilovolts (kV)). These high operating voltages necessitate longer traveling-wave circuits and significantly increase the size and weight of the amplifier (particularly the permanent magnet focusing system) and the power supply. Lower operating voltages have obvious benefits in the size, weight, reliability, and cost of VE amplifiers. However, achieving high power at low voltage is quite difficult and generally requires a distributed electron beam (for example, multiple parallel beams) to achieve high current at low voltage. As an example of the impressive performance made possible by a low-voltage, multiple-beam approach, engineers at Istok Corporation, Russia, have reported 1-kiloWatt (kW) narrow-band amplifiers at frequencies of 15 -17 Gigahertz (GHz) (Ref.1). These amplifiers operate at voltages of a few kilovolts and have a specific power density of about 1 kiloWatt/kilogram (kW/kg) (including the magnet). Expansion of this low-voltage, multiple-beam technology to wide-band MMW slow-wave amplifiers has great potential for the development of lightweight, high-specific-power-density miniature traveling-wave tube (TWT) amplifiers suitable for applications on a wide variety of platforms. However, significant improvements in beam brightness are needed to transport the multiple beams through the smaller diameter beam tunnels required for higher frequency traveling-wave circuits. To enable the development of high-power, compact, low-voltage MMW amplifiers, the Navy is seeking innovative electron gun and permanent magnet beam transport approaches based on multiple-beam technology. Compact, multiple-beam devices represent an emerging technology made possible by recent advances in three-dimensional computational modeling (Refs. 2, 3) and the development of advanced high-current-density thermionic cathodes (Ref. 4). The focus of this effort is development of the multiple-beam gun and corresponding permanent magnet design for integration with a compatible Ka-band circuit. The specific power density is a key metric. A successful design will exceed 500 Watts/kilogram (W/kg), which includes the weight of the magnets. The new technology will be consistent with a compact transmitter footprint with minimized system cost, and minimal beam interception from the electron gun to the collector. An expected by-product of the research and development of the hardware is the establishment of a design methodology, scalable in power and frequency, which makes use of and expands upon the potential of modern 3-Dimensional (3D) design codes. PHASE I: The company will develop a concept for a multiple-beam electron gun and permanent magnet transport system that meets the requirements as stated in the description section. The company will demonstrate the feasibility of the concept in meeting Navy needs and will establish that the concept can be feasibly developed into a useful product for the Navy. Analytical methods or computational modeling will establish feasibility. PHASE II: Based on the results of Phase I and the Phase II contract statement of work, the company will develop a prototype multiple-beam electron gun and permanent magnet transport system for evaluation. The prototype will be evaluated to determine its capability in meeting Navy requirements for the multiple-beam electron gun and permanent magnet transport system. Evaluation results will be used to refine the prototype into a design that will meet Navy requirements. The company will prepare a Phase III development plan to transition the technology for Navy use. PHASE III: The company will be expected to support the Navy in transitioning the technology for Navy use. The company will develop the multiple-beam electron gun and permanent magnet transport system according to the Phase III development plan for evaluation to determine its effectiveness in an operationally relevant environment. The company will support the Navy for test and validation to certify and qualify the system for Navy use. PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: Commercial applications of multiple-beam amplifier technology include broadband high-power amplifiers for commercial satellite up-links and point-to-multipoint wireless broadband “last mile” applications, where the low operating voltage is attractive due to reduced costs and increased reliability.

OBJECTIVE: Develop an innovative automated detection capability for Navy submarine combat systems to detect possible contacts at long ranges at, or near, the horizon. DESCRIPTION: The Navy seeks an automated visual detection software capability to improve 360-degree situational awareness for its submarine fleet. Littoral operations frequently involve navigating around a large number of marine contacts, such as fishing fleets, which may be intermingled with potentially hostile targets. Manual visual detection of small contacts and long-range contacts on, or near, the horizon from low vantage points while sweeping the periscope through 360 degrees is difficult for periscope operators. Environmental conditions on the ocean can make the manual contact detection process even more difficult. Commercial radar used by ships for situational awareness cannot be applied to submarines at periscope depth. Digital imaging systems offer the potential for rapid and accurate contact detection at longer ranges than manual visual detection. Previous attempts at visual ship detection have been limited to larger contacts, high vantage points, and other imaging systems such as buoy cameras and stationary cameras in port (Ref 1-3). |
