Department of War Office of the Assistant Secretary of War OASW(EI&E) Resilient Infrastructure and Layered Passive Survivability

Solicitation # JP10212026

The Department of War, through the Office of the Assistant Secretary of War for Energy, Installations, and Environment, has issued Request for Information JP10212026 to gather concepts and technical insights for the development of the Base of the Future. This initiative focuses on transitioning installation frameworks to support an active operational posture by enhancing resilient infrastructure and layered passive survivability. The Department is seeking non-prescriptive solutions to move beyond traditional hardening methods, focusing instead on minimizing target signatures, dynamically absorbing kinetic energy, and maintaining mission-essential functions during active degradation. The scope of this market research is divided into four capability-based domains: advanced materials and physical hardening, subterranean and deep-earth engineering, signature management and deception, and spatial dispersal and system-level resilience. The government intends to use the gathered information to identify mature technologies for immediate integration into military construction standards and to guide future research and development funding. This RFI is issued solely for planning purposes and does not constitute a solicitation or a binding contract. Responses must be unclassified, delivered in a searchable PDF format, and limited to twenty pages, excluding technical drawings and capability statements. Submissions must include a cover sheet with the company name, point of contact, CAGE code, and corporate capability designation. The response deadline is November 6, 2026.

The Department of Defense is seeking vendors to enhance the Space Systems Command Ionospheric Ground Sensors network to provide a more comprehensive, real-time picture of the ionosphere. The primary goal is to transition from sensors that only observe directly overhead to an oblique-sensing capability. This initiative involves prototyping and validating an oblique NEXION sensor baseline, developing rapid integration methods for software and firmware, and upgrading ISTO receive antennas to increase overall data density and sensing capabilities. Key technical requirements include the implementation of a cyber-resilient patch deployment process and an integrated engineering approach to deliver data to the Unified Data Library. The project aims to establish a fieldable long-term engineering design that improves space weather forecasts and satellite anomaly assessments without reducing network availability. This solicitation allows for multiple awards, with companies eligible to propose solutions for one or more lines of effort.

Tactical Maritime Intelligence: Adaptive AI and Autonomy at the Tactical Edge

Solicitation # 19bc3e11-0a9e-4ea9-9945-16ee3f8952c2

The National Geospatial-Intelligence Agency, in coordination with the Office of Naval Intelligence and Army Contracting Command, is seeking to prototype an artificial intelligence-enabled computer vision capability designed for tactical maritime intelligence at the edge. The project aims to solve critical gaps in vessel detection, tracking, and re-identification within contested maritime environments where low connectivity and limited cloud access currently hinder performance. The goal is to provide warfighters with a tool that maintains continuous custody of vessels of interest without requiring extensive coding expertise or large amounts of labeled data for retraining. The resulting prototype must operate on size, weight, and power-constrained hardware and integrate with standard GEOINT data formats and tactical dissemination systems, including the TAK ecosystem and REST API architectures. Success will be measured by the model's ability to meet specific precision, recall, and F1 thresholds while functioning independently of cloud infrastructure. This effort will ultimately provide documented performance outcomes to guide future transition and development decisions essential for national security and tactical maritime operations.
