    As emerging technology spurs new requirements for the development and acquisition of increasingly advanced military platforms, the defense acquisition community needs a comprehensive decision-support framework to make informed investment decisions for software selection. Through a determination of key characteristics that form the basis of a decision process, this report outlines a framework for software selection that includes cost, schedule, and performance considerations. Furthermore, the resultant software selection criteria are subject to a practical demonstration to compare the following software packages that predict hydrodynamic loads: Standard Ship Motion Program (SMP), SUBMOT, Aegir, and Large Amplitude Motion Program (LAMP). The creation of a uniform set of simulation input data, for use with these four candidate software packages, details this selection process. We present a comparison of the software-generated data with experiment data gathered from tow tank trials as an analysis of tradeoffs between cost, schedule, performance, and simulation fidelity. The practical demonstration showed that Aegir and LAMP were more labor-intensive than the other software packages and that Aegir and LAMP simulation results were typically closer to the scale model experiment results. Resulting recommendations include decision-support framework application and fidelity analysis prior to software selection for most effective program support.

    The United States Marine Corps (USMC) is developing the Future Vertical Lift (FVL) system that will rely heavily on Marine-machine teaming, a complex process that requires further development. The development of a living lab (LL)—a multi-function network of simulators that will serve as the platform for testing, experimenting, and training new technologies and ideas for how the FVL will operate—will help mitigate Marine-machine collaboration and trust issues. This capstone studies the options and requirements for developing a LL through interviews, research that focuses on existing technologies and operational concepts, and Model-Based Systems Engineering tools using a systems engineering approach. The report includes a detailed needs and requirements analysis, stakeholder analysis, and functional design. The team presents a conceptual design, that includes the system architecture, comprising of system, function and physical views, system lifecycle, and the evaluation criteria for a LL. The final product is a set of use cases and concepts of operation. The USMC needs a new approach that supports rapid and relevant upgrades that optimizes the system lifecycle and keeps the Marine in mind. This team recommends the USMC consider these findings and continue researching and developing a LL.

    Methods of communication have increased greatly over the past 25 years. Faster, more targeted communication enables organizations to influence their audience with greater precision and achieve their effect with greater impact on those receiving the message. Communication has moved from the days of broadcasting (equivalent to the basic "dumb bomb") to targeted messaging aimed at specific groups or even individuals (equivalent to today's precision-guided munitions [PGM]). Targeted information is a "PGM" the Army can use to achieve a number of desired goals if that "weapon" is employed properly. Recruiting is a prime example of where precisely targeted communication can benefit the Army. The communications network, which includes messages, mediums, outlets, and audience, is a system that can be analyzed at its nodes and arc capacitance. Moreover, the operational effectiveness of the system is an area of analysis that will have an impact on the design and development of the network.

    Hypersonic glide body weapons represent a revolutionary change in offensive capabilities for militaries around the world. The U.S. Navy is developing a hypersonic glide body capability with the Conventional Prompt Strike Program, which has a scheduled initial operational capability of 2025. This capstone project has developed candidate systems that describe how the Army's Long Range Hypersonic Weapon (LRHW) system could be integrated onto various vessels to deliver a hypersonic glide body capability to the Navy before the Conventional Prompt Strike Program is operational. Research indicates that the LRHW is the most mature hypersonic glide body system developed by the United States, and integrating its use aboard Navy ships is the most likely path to success. This capstone describes the user concerns, system requirements, and concepts of operation through the development of systems engineering products that describe each of the candidate systems.

    This research effort examined the current advanced battery requirement (baseline) and projects anticipated battery requirements for the operating force in 2035 and 2045. The research is conducted using a mission engineering perspective to determine the battery requirements. The analysis includes battery chemistry, energy density, charge/discharge rate, safety concerns, and the like, of the battery. In this research the following questions are answered: What is the current advanced battery requirement (baseline)? What is the projection for batteries required by the operating force by 2035? What is the projection for batteries required by the operating force by 2045? Upon completion of the research, the team was able to definitively determine that there will be a role for Li-ion batteries within the fleet of Navy vessels. That role will, however, be limited to running specific subsystems or equipment and will not replace the ship generators. This will remain true until the energy density of battery technology even begins to approach that of petrochemicals, which we believe is many years away if possible.

    One of the global security challenges the United States faces is disaster coupled with political instability. The U.S. Military‘s ability to rapidly respond to disasters enhances regional and global security and stability. Foreign Humanitarian Assistance and Disaster Relief (FHA/DR), increasingly a mission that relies on a significant military component, focuses on the provision of goods and services such as health care, supplies necessary for survival, and infrastructure repair, with the goal of reducing the immediate human suffering. The disaster in this project‘s scenario is catastrophic flooding that occurs in one of Africa‘s most populated and wealthiest countries that threatens the stability and development of West Africa. This project, employing a systems engineering methodology, focuses on the 60 days after the disaster and the requirements to provide this assistance in the form of goods and services. Many system-of-systems architectures were developed to investigate the effectiveness of utilizing a Seabase for the primary delivery of aid. Two simulation tools, SimKit, and STELLA, were used to model and examine these architectures with the former addressing the delivery and throughput concerns while the latter focused on the satisfaction of the population and the limitation of criminal activity. Based on the results of modeling, the team provided recommendations relative to the most effective architectures in influencing the population of this coastal area as well as accomplishing the FHA/DR mission.

    Energy security is becoming increasingly important as the DOD relies on energy to build and project combat power from military installations. Installation energy managers currently ensure uninterrupted power to mission-critical facilities through emergency stand-alone diesel generators. Research has recently indicated that networks of smaller diesel generators offer greater energy security benefits than a network of a few large diesel generators. However, existing research has not compared or analyzed the cost and resilience between the two strategies. This capstone examines the cost and resilience of centralized and decentralized power architectures by developing a general methodology to capture comprehensive life-cycle costs and metrics. It examines resilience for various configurations of networked diesel generators. Installation power managers can apply this method to quantitatively compare life-cycle cost and resilience of emergency diesel generator solutions to improve energy security within the unique constraints of an installation. The capstone then applied this methodology to the aging diesel generator power plant at Naval Station, Rota, Spain, which demonstrated that decentralized architecture was the most cost-effective strategy for resilience. Finally, the capstone presents these findings and general methodology for future application.

    This capstone report examines the concept of combining mobile and stationary underwater sensors into a coherent, distributive network. This project presents a baseline architecture for a data fusion system that facilitates the near real-time exchange of information from disparate sources. This architecture, in turn, provides a basis for further system development, and guides future studies of relevant data/information fusion concepts and technologies for applications to anti-submarine warfare (ASW) and mine warfare. This study uses the unique approach of inverse systems engineering to design an architecture based on the ASW kill chain, and the probability of success in detecting, classifying and tracking underwater objects. The probability of success is then measured against the same probability of success of a human ASW operator to determine the adequacy of design. The team utilized ExtendSim software to model and simulate the architecture to validate functional capability and improved performance over the human ASW operator. The resulting architecture facilitates the successful integration of passive acoustic sensor information with intelligence products and timely distribution of fused data across manned and unmanned platforms. The architecture also allows for future growth into active acoustic sources, environmental data sources, non-traditional ASW sources such as radar, and ESM.

    The capstone assesses the makeup and capabilities of Multi-mission Reconnaissance Craft (MMRC) squadrons in view of how effectively they could accomplish a given mission. This effort consisted of the development of a MMRC squadron system architecture, which describes the functional and operational use of the MMRC squadron within the Littoral Operations Area (LOA). Within the defined architecture, various measures of effectiveness (MOE) were analyzed to determine which metrics were most relevant to evaluate the successful employment of the MMRC squadrons. Simulations were developed in Map Aware Non-Uniform Automata (MANA) for a subset of missions in both a competition scenario and a conflict scenario, and a design of experiments was developed for each scenario. Regression analysis was conducted on the resulting data for each of the three MOEs in each scenario. While significant factors varied per each MOE, radar classification range and aperture arc overall played a significant role, suggesting that MMRC design should focus on procuring the best possible radar. For conflict, radar factors also played a significant role, alongside the number of hits it took to "kill" the MMRC. This suggests that focusing on durable design is an important part of ensuring success on missions in active conflict.
