The Department of Defense, specifically the Navy, is seeking proposals for the development of a Modeling and Simulation (M&S) tool focused on logistic modeling for hypersonic weapon systems. This tool aims to analyze various physical effects during the pre-launch, launch, and post-launch phases, ensuring the integrity and health of the weapon system while identifying potential points of failure. The M&S capability will be crucial for integration experts and logistics assessment professionals, aiding in mission planning and technology requirements for high-speed weapons and space systems. Interested parties should note that the solicitation is set to open on April 23, 2025, with proposals due by May 21, 2025, and further details can be found at the provided source link: https://www.dodsbirsttr.mil/topics-app/.

## Description

The M&amp;S tool will need to consider combinations of various physical effects during pre-launch, launch, and post-launch that affect the integrity and health of the weapon system and finds points of failure. For the pre-launch phase, the tool will need to predict the overall internal temperature of the system due to excess heat generated by onboard electronics, determine possible launch windows that fit within the constraints of onboard systems and/or external environmental conditions, and vibrations during deployment but prior to launch. For the launch phase, the tool will need to predict the overall impact of shocks, vibrations, and accelerations on components during launch. For the post-launch phase, the tool will need to track heating rates from external aerodynamics and internal electronics, Concepts of Operations (CONOPS)- driven vehicle reorientations, required operating windows for onboard systems, externally received signals, and computation time to react to new commands during flight. The tool will also need to calculate timing to inform logistics analysis, like mean time between failures (MTBF) for technologies affected by the conditions described for each phase. This tool will be used by integration experts, logistics assessment experts, and mission planning. This will aid in the confidence of the logistic assessment, storage, transportation, and technology requirements. This M&amp;S capability must be able to modularly accept reference information generated by high fidelity physical models, such as equations, look-up tables, or state information. This project will transition to defense contractors for high-speed weapons and space systems. To meet these needs, maturation and packaging of the technology to meet practical size, weight, and power constraints will be required. Extreme environments may require special considerations to conform to airframe shape and shielding from the aerothermal environment. Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. owned and operated with no foreign influence as defined by 32 U.S.C. &sect; 2004.20 et seq., National Industrial Security Program Executive Agent and Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence and Security Agency (DCSA) formerly Defense Security Service (DSS). The selected contractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances. This will allow contractor personnel to perform on advanced phases of this project as set forth by DCSA and SSP in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material during the advanced phases of this contract IAW the National Industrial Security Program Operating Manual (NISPOM), which can be found at Title 32, Part 2004.20 of the Code of Federal Regulations.

## Objective

Develop a Modeling and Simulation (M&amp;S) tool that is capable of capturing timing windows for different phases of the weapon system&rsquo;s operational lifecycle based on system, subsystem, and component requirements, weapon system Concept of Operations (CONOPS), and dependencies on external systems or institutions. This tool must be able to determine the minimum and maximum allowable times for certain events based on relevant factors including but not limited to heating rates and receipt of critical mission data during operational use.

## Phase I

Provide a concept for a logistics M&amp;S capability that can capture timing windows for different phases of a weapon system&rsquo;s operational lifecycle based on system. Ensure that the concept addresses the generation of timing predictions for the pre-launch and post-launch phases using approximations of relevant environmental information or operational constraints of systems. Include heating information that can be represented by polynomial functions over time, piecewise or not, or as tabular lookups. Develop heating models that consider sub 300 degrees Celsius (&deg;C) for the pre-launch phase and greater than 1,000&deg;C for the post-launch phase. Demonstrate models of various conditions that may be present pre-launch, during launch, and post-launch. Provide computational calculation times that can be represented by simple equations to determine how long different phases of calculation last, capturing time to receive and process a command, recalculate, and deploy the command with respect to the remaining time in the mission. If the Phase I Option is exercised, include the initial design specifications and capabilities description to build a prototype solution in Phase II. Prepare a Phase II plan.

## Phase II

The Phase II effort will require the ability to perform work in a classified environment. Concepts presented in Phase I will need to work with classified reference values. Develop a prototype M&amp;S tool that can generate parametrically based on mission parameters. Apply and further develop the prototype for specific cases prioritized by the Conventional Prompt Strike (CPS) program and begin using program data. It is probable that the work under this effort will be classified under Phase II (see Description section for details).

## Phase III: Dual Use Applications

If the demonstration in Phase II is deemed to be of high interest to the Government, support the Government in transitioning the technology for Government use to support current and future weapon and space systems, as well as a wide range of other air-, land-, and sea-based systems. Commercial applications should be considered for transition (i.e., 5G, navigation systems, and tracking systems).
