Nanotechnology Orchestrated Viral Annihilation (NOVA) – DTRA

Solicitation # 5fc9b9c3-3c66-4cf1-bd23-c37a93301889

The Department of Defense, through the Defense Threat Reduction Agency, is seeking prototypes for nanotechnology-based medical countermeasures to protect warfighters from multiple viral threats. Moving away from the traditional one-virus, one-countermeasure model, this initiative aims to develop broad-spectrum, biocompatible, and biodegradable solutions capable of functioning in both pre- and post-exposure scenarios. The goal is to create a versatile platform that can neutralize various viruses while simultaneously mitigating inflammatory fallout from preexisting infections. The project is divided into three lines of effort focusing on prototype demonstration, ruggedization, and scalability. The first phase requires a prototype that demonstrates activity against at least five viruses in vitro and one virus in vivo, utilizing cellular decoy and immunomodulatory mechanisms. The second phase focuses on creating heat-stable, ruggedized formulations suitable for multiple administration routes in austere environments. Finally, the effort requires the development of a scalable manufacturing process and a defined regulatory pathway toward FDA licensure to ensure the technology can transition from nonclinical demonstration to clinical use.

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.
