RFI for Modeling and Simulation Software

The Defense Threat Reduction Agency (DTRA) has issued a Request for Information (RFI) under solicitation number HDTRA1-26-MS-SW to explore the availability of modeling and simulation software capable of assessing physical security vulnerabilities across Department of Defense installations. The RFI seeks vendors with the ability to deliver a software platform that can build and render 2D and 3D facility models, simulate diverse threat scenarios—including insider threats, cyber attacks, and blast events—and perform probabilistic risk assessments using Monte Carlo methods to automatically identify attack pathways and quantify vulnerabilities. The software must support interactive visualization, generate statistical and physics-based analytical outputs, and include an integrated training environment for real-time force-on-force simulations. All solutions must have completed Validation, Verification, and Accreditation (VV&A) in accordance with DoD standards. The submission deadline is May 20, 2026, and responses are to be directed to DTRA at Fort Belvoir, Virginia, though no specific electronic submission method is required. Respondents must hold an active Top Secret security clearance, and no classified information is permitted in submissions; proprietary data must be clearly marked, while the government reserves unrestricted rights to use non-proprietary technical information. While this RFI is strictly for market research and does not obligate the government to issue a contract or award funds, future solicitation will likely evaluate technical capabilities such as adversary behavior modeling, integrated physical-cyber threat simulation, and automated vulnerability identification. No pricing, delivery timelines, or contract line items are included, and no formal evaluation factors, weights, or award basis have been defined, though a trade-off process is anticipated given the technical complexity. Offerors must provide their UEI or CAGE code, indicate their size status and socioeconomic designation, and demonstrate relevant experience. The place of performance is Fort Belvoir, VA, and while no delivery, packaging, or invoicing requirements are specified at this stage, the software will ultimately support the Nuclear Enterprise and Nuclear Surety Department within DTRA.
