OUSD (R&E) MODERNIZATION PRIORITY: Autonomy, Hypersonics, Space TECHNOLOGY AREA(S): Weapons The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), 22 CFR Parts 120-130, which controls the export and import of defense-related material and services, including export of sensitive technical data, or the Export Administration Regulation (EAR), 15 CFR Parts 730-774, which controls dual use items. 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 the Announcement. 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: To develop sensing technologies that enable the receipt and transmission of high-precision, dynamic retargeting data for long-range munitions. Technologies to be developed would provide the means to remove humans as forward observers, especially for long range munitions, with low probably of detection. DESCRIPTION: This topic addresses enhanced capabilities for three different engagement scenarios. The first scenario involves target information that is to be modified based on reprioritization of targets. The second scenario addresses the delay of target information either because the precise target location is initially unavailable, because the target is moving, or because the munition's destination is to be concealed from enemy forces. The third scenario involves guiding the munition real time to the target through an operator or an autonomous system. The delivered technology will enable the munition to sense, geolocate, and relay target and munition data from multiple sources to fire control and battle management systems. The proposed technology should also provide the means to transmit actual position data that can be used by onboard navigational system to determine if the GPS signal is being spoofed and to take appropriate corrective action. PHASE I: Conduct a systematic feasibility study of the proposed methods using analytical and computer modeling and simulation and well as proof-of-concept prototyping of the basic components of the system and laboratory testing to determine if they have the potential of meeting the all the requirements for use in munitions, UAVs and UGVs that are to be provided to the Phase I awardees. Manufacturability of the proposed concepts and compatibility with mass production technologies used in similar commercial applications to achieve low cost and highly reliable systems must also be addressed. The Phase I effort must also address shelf life and safety issues and provide a detailed plan for the development of concepts, along with their prototyping and testing during the project Phase II period. PHASE II: Design and fabricate full-scale gun hardened energy system prototypes of the selected concepts for the selected munitions applications and test prototypes in the laboratory and in relevant environments, including in shock loading machines and in air guns. Demonstrate that such prototypes can survive in operational environments while performing the designed transfer of sensory information for moving targets and dynamic retargeting under various conditions. The Phase II period must also include the fabrication and delivery of final prototypes of the selected design for the selected munitions applications. PHASE III DUAL USE APPLICATIONS: The developed technology has a wide range of military applications for remote sensing and targeting, including in UAVs, UGVs and remotely operated robotic systems. Commercial uses for such technology also include remote sensing and dynamic tracking and delivery of payloads or services using UAVs, UGVs and remotely operated robotic systems, particularly to remote locations and in emergency conditions.
