| PHASE III: The company will support the Navy in transitioning the technology for Navy use. The company will develop a Band-pass Sampled, Digital Downconversion 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 and transition the downconversion system to its intended platform.
PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: Direct digital downconversion has application to the commercial radar market as well as additional military applications. The proliferation of small solid-state radars for remote sensing and navigation benefits from cost-saving digital technologies that drive affordability and consequently expand the market even further. The commercial market is typically quick to adopt technology that enhances performance while controlling cost. The technology developed under this effort will facilitate a shift from expensive RF analog receiver circuitry to receivers based on commercial microprocessor technology. Even complex commercial radars such as weather radar can benefit from this technology, as digital processing is inherently scalable, allowing radars of various size and complexity to achieve improved performance at reduced cost.

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 effective, flexible, and affordable submarine detection system consisting of acoustic sensing and a Magnetic Anomaly Detector (MAD) capability for a Vertical Take Off and Landing Tactical Unmanned Aerial Vehicle (VTUAV) to be used by any ship capable of launching and recovering a VTUAV (e.g., Fire Scout or equivalent capabilities). DESCRIPTION: The current approach to air platform submarine detection is deployment of dipping sonars from MH-60 helicopters, full size sonobuoys (ref 2, 3) deployed from MH-60 helicopters and land-based P-3 aircraft, and Magnetic Anomaly Detectors (MAD) (ref 1) on fixed wing aircraft and helicopters (ref 1). While effective, these approaches are labor intensive, consume large amounts of fuel, and are costly. In addition, platforms such as the Littoral Combat Ships (LCS) that carry only one ASW-equipped helicopter have a less than optimal ASW capability. The Navy has identified a need for an Ultra-lightweight Airborne Deployment/Retrieval Sensor acoustic sensor capability in a “podded” system. This system can then be installed and removed rapidly on an MQ-8C Fire Scout Vertical Takeoff Unmanned Air Vehicle (VTUAV) to provide an adjunct ASW capability for the MH-60R. The proposed system will provide a low cost, lightweight, unmanned capability to complement current helicopter ASW operations. This topic seeks a compact, affordable, energy efficient, acoustic sensing capability for a Fire Scout, or similar VTUAV. In addition, the VTUAV will use a Magnetic Anomaly Detector to complement the acoustic search for submarines. The desired system will increase the affordability of anti-submarine searches by lowering overall cost that currently requires a helicopter such as the MH-60. In addition, an Unmanned Aerial Vehicle (UAV) does not require an on-board crew. The proposed system should be usable by any ship capable of launching and recovering a VTUAV. The system would employ the VTUAV to perform acoustic sensing ahead of the host ship. The sensing could be “stand alone” or as part of a bi-static system, with the active source on the host ship or on a different platform. The system could employ a tethered approach for sensor deployment and retrieval or a traditional air launch deployment or combination. Littoral Combat Ships (LCS) have particular platforms of interest, though the VTUAV capability would not be restricted to a LCS. The technologies for ASW acoustic sensing and magnetic anomaly detection are mature. Offerors are encouraged to consider using or adapting existing sensing and deployment technologies as much as possible. The innovation described in this topic requires several considerations. One is the design, development, and integration into the VTUAV of a compact, reliable, affordable system. A second includes launch and/or retrieval of acoustic capability. A third is designing to the Size, Weight and Power (SWaP) limitations of a VTAUV (SWaP requirements will be provided in a SITIS document). A fourth is minimizing the effects of noise from the VTAUV. A fifth is the fusion of acoustic and magnetic field data. In addition, the fused data must interface with the VTAUV’s data communication and vehicle control system on the host ship. PHASE I: The Company will define and develop a concept for VTUAV mobile acoustic sensor(s) and MAD capability that meet the objectives as stated in the topic description. The company will demonstrate the feasibility of the concept in meeting Navy needs and will establish that the concept can be developed into a useful system for the Navy. Feasibility will be established by analytical modeling. PHASE II: Based on the results of Phase I, the small business will develop a prototype for evaluation. The prototype will be evaluated to determine its capability in meeting performance goals and Navy requirements. System performance will be demonstrated through prototype evaluation and modeling over the required range of parameters including numerous deployment cycles. Evaluation results will be used to refine the prototype into an initial design that will meet Navy requirements. The company will prepare a Phase III development plan to transition the technology to Navy use. PHASE III: Based on the results of Phase II, demonstration in a realistic environment is planned. The company will support the Navy in transitioning the technology for Navy use. The company will develop the submarine detection 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: This technology will be useful in commercial underwater applications, to include the fields of oceanography and undersea search and recovery.

OBJECTIVE: Develop a new Submarine Imaging Mast Direction Finding (DF) capability for the Next Generation Submarine Electronic Warfare (EW) System. DESCRIPTION: All Combatant Commands (COCOMs) have identified EW and Intelligence, Surveillance, and Reconnaissance (ISR) improvements, to support Force Application and Battlespace Awareness, as one of their highest priorities (ref 4,5). For submarines to meet the future COCOM ISR requirements they will need to improve the Direction Finding (DF) capability in the imaging mast. The proposed solutions to improve submarine DF must conform to open standards and approaches in the hardware and software design that shall readily support technological and functional advancement of the systems capabilities. DF is critical to improved situational awareness, ISR mission effectiveness, and overall ship safe operations particularly in the littoral operating regions. The Next Generation Submarine EW system requires a DF capability that will be included in all future systems. This DF system will need to use common RF components, data pathways, and common processing capabilities to be included in the next generation architecture. It will need to be modular, scalable and fit into the digital framework, and current and future submarine mast configurations. The current DF system for Virginia Class submarines has six spiral DF horns that feed into a task tuned filtered bank (500 MHz instantaneous bandwidth) that provides an Intermediate Frequency that is converted to video via a set of SDLVA’s. Each of these six video lines are available inboard for DF processing. Unfortunately, this current design severely limits the DF capability across the broad spectrum of radar emission operating today. Current Submarine DF capabilities are closely coupled with the radar wideband components in a stove-piped architecture. The current architecture does not allow for cost effective improvements in system performance and the introduction of new capabilities without significant impact to the existing system. Another limitation of the current configuration is that RF information (for the DF antennas) is turned to video in the mast and therefore only video (amplitude) processing can be performed with the below decks equipment (ref 1). The Next Generation Submarine EW system will need to provide Direction Finding applications and solutions using available data from the existing DF arrays. This data will be defined through the interface layer of the new architecture, allowing algorithms in the processing layer to be developed for increased accuracy and capability. The challenge is to improve direction finding in the constrained environment of submarine apertures and the RF environment. The use of digital data is preferred but the space constraint for turning the DF spiral RF into digital data is a confined space outboard of 3” x 3” x 10”. It is preferred that DF improvements are predominately software based solutions but hardware and software solutions will be entertained. The small business will have to work closely with the government to ensure that the proposed solutions are feasible in the current (and future) submarine mast constraints (extremely small volumes and very thick radomes) (ref 2,3). PHASE I: The company will define and develop concepts for a submarine imaging mast DF capability that meet the requirements as stated in the topic description. The company will demonstrate the feasibility of the concept in meeting Navy needs and will establish that the concept can be developed into a useful product for the Navy. Feasibility will be established by analytical modeling. PHASE II: Based on the results of Phase I, the company will develop a DF prototype for evaluation. The prototype will be evaluated to determine its capability in meeting performance goals and Navy requirements for a Next Generation EW Digital DF for submarines. System performance will be demonstrated through prototype evaluation and modeling or analytical methods over the required range of parameters including numerous deployment cycles. 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 that will provide requirements to transition the technology for Navy use. PHASE III: If Phase II is successful, the company will support the Navy in transitioning the technology for Navy use. The company will develop a Next Generation EW Digital DF for submarines 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: Government commercialization will be applicable across all submarine EW platforms. Modular DF techniques should be applicable to other Navy collection platforms (Triton, Firescout, EP-3, etc.). Commercial applicability could be utilized in other agencies and potentially in the TELCOM industry for finding and localizing offending RF emissions. REFERENCES: 1. Wiley, R.

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 a Reserve Power Solution for Navy Conventional Ammunition Fuzes that meets current and future Naval ammunition fuzing requirements. DESCRIPTION: The primary fuzes for the Navy’s 5” suite of ammunition, the MK 437 Multi-Option Fuze (MOFN) and the MK 419 MOD 1 Multi-Function Fuze (MFF), currently face obsolescence and sourcing issues with their reserve batteries. These reserve batteries are liquid based. The cathode material for the MOFN battery is obsolete and the MFF battery is sourced from overseas (Germany). The technological obsolescence and strategic sourcing issues of the fuzes’ batteries puts the Navy’s ability to arm its ships with modern, reliable, and precise Naval Gun Weapon Systems at risk. Given these shortcomings, this presents an opportunity to acquire an advanced reserve battery with the technology to support both current and future Naval ammunition fuzing requirements. Thermal batteries present an interesting solution given their inherent environmentally and electrically safe design, long shelf life, and zero maintenance. A new battery is required to sustain production of the Navy’s suite of 5" high explosive ammunition. Thermal batteries are a promising technology for potential fuze power. Thermal batteries have been extensively developed in the United States and represent a stronger industrial base than a liquid reserve battery alternative (ref 1). While the thermal battery technology presents many advantages as a reserve battery, there are technological challenges impeding their application in Navy 5” electrical fuzing applications. Reserve thermal batteries are a single use, high temperature, galvanic primary cell battery (ref 2). These batteries have been demonstrated to be environmentally safe and have a long shelf life which is ideal for military purposes (ref 1). Thermal battery composition allows it to withstand the severe environment of Navy gun ammunition, particularly acceleration, shock, vibration, and spin. They are reliable, safe, provide instantaneous activation, do not require maintenance, have chemicals which are inert until activated, and are designed to facilitate power or capacity improvements. The high conductivity of the electrolyte at high temperatures allows the battery to be discharged at high rates. Thermal battery applications and characteristics allow a design to meet specific electrical and environmental parameters (ref 3). Thermal batteries present a favorable solution given their inherent environmentally and electrically safe design, long shelf life, and zero maintenance. Thermal batteries have a rise time that is directly proportional to their size while their run time is dependent on maintaining elevated temperatures. For Navy fuzing applications, this presents conflicting requirements as the reserve battery is required to rise to operating voltage very quickly and precisely while providing power for the relatively long time of flight. As a result, a large battery that might provide for the flight time would fail the rise time and volume allocation requirement. However, a smaller battery might address the rise time and volume allocation requirement but fail the flight time requirement. Currently, thermal batteries with a volume of 15-20 cubic centimeters cannot be designed to provide electrical power longer than around 50 seconds. Naval 5" conventional ammunition fuze applications require batteries that can withstand setback launch forces and spin rates. Battery volume must also meet set requirements for fuze applications. The electrical requirements must meet current standards for nominal voltage, current draw, and run, and rise times. Specific innovations in both thermal battery heat management and scalable packaging efficiency to improve performance are required to meet these needs (ref 4). Based on current ammunition fuze electrical requirements, a nominal voltage of about 12V, current draw of up to 325 mA, runtime of 200 seconds, and a rise time of less than 10ms with a standard deviation of about 1ms is expected. This reserve power solution will include scalable thermal battery packaging meeting requirements of Navy 5" conventional fuzing. PHASE I: The company will identify and design a concept for a Reserve Power Solution for Navy Conventional Ammunition Fuzes that meet the requirements as stated in the topic description. The company will demonstrate the feasibility of the concept in meeting Navy needs and will establish that the concept can be 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, the company will develop a prototype for evaluation. The prototype will be evaluated to determine its capability in meeting the performance goals and Navy requirements for a Reserve Power Solution for Navy Conventional Ammunition Fuzes. System performance will be demonstrated through prototype evaluation and modeling or analytical methods over the required range of parameters including numerous deployment cycles. 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 support the Navy in transitioning the technology for Navy use. The company will develop a Reserve Power Solution for Navy Conventional Ammunition Fuzes 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: Thermal batteries present an attractive solution for both military and commercial needs due to their power output, zero maintenance requirements, and available small form factors. The Navy’s requirement for increased runtimes in an even smaller package increases the technology’s commercial attractiveness. For example, thermal batteries have found use in the Mars pathfinder exploration, used to propel the parachute motors, and other on-board rockets. This could be the beginning of a series of discoveries that could be applied to other fields. REFERENCES: 1. Davis, P. B. & Winchester, C. S.
