The distance learning team was tasked to produce an architecture that would best support future Operationally Responsive Space requirements in the 2025 timeframe. The 'bottom line up front' to this analysis showed that the current space architecture already provides some level of responsiveness. However, ORS will demand modifications of the current space architecture vice certain pre-conceived notions of quick launch or a separate ORS architecture altogether. The team developed a 'baseline' vision for deeper analysis focused on the Combatant Commander supported by analytical categories named 'Pillars' as follows: Improved Organizational Relationships, Asset Loss Mitigation, Availability, Flexibility, and Streamlined Acquisition Processes. These pillars allowed the solutions, material and non-material, to be organized for further analysis, relevancy, and value to the architecture. Constraints and alternative solutions were considered. Analysis was further supported by a performance versus cost process which provided a final test of solution feasibility. Relative cost was determined by comparison of existing program or like capabilities with future inflation. Differing combinations of solutions could provide ORS value by modification of the metrics. The final analysis showed an Operationally Responsive Space architecture that meets all metrics and that could support all COCOM requirements.
The Unites States' first space systems programs were initially developed to meet the requirements of strategic users. Since the 1991 Gulf War there has been a growing dependence on the capabilities and support delivered by these programs to meet the requirements of nonstrategic users. The current National Security Space (NSS) architecture makes it rather difficult for all but critical strategic users to fully capitalize on the available assets. Timelines that were once adequate to deliver strategic capabilities are now not sufficient to allow a broader range of users to realize the benefit from using the available space systems. In addition, nonstrategic users run into challenges when they attempt to change the tasking requirements that would enable them to receive associated products and services that are useful and timely. With the identified gaps in the current NSS environment, the Integrated Product Team (IPT), consisting of 10 active duty military students, sought solutions to make space more "Operationally Responsive" (ORS) to its customers by 2025. Due to limited time and assets, the IPT narrowed the focus of the project to the four Joint Publication (JP) 3-14 "Joint Doctrine for Space Operations" mission areas of Space Support, Space Control, Force Enhancement, and Force Application. During this project, the IPT defined ORS from its perspective, developed the requirements to meet the identified NSS gaps, selected the final alternatives to satisfy those requirements, and suggested an implementation plan. While in the architecture process, the IPT conducted an in-depth evaluation of the original alternatives based on Responsiveness, Risk, Capability, and Cost. After building a foundation for further analysis, a total of 16 alternatives were chosen for the final ORS architecture. The alternative that provided the most responsiveness was to create a Single Space Agency.
Tactical space support has earned a reputation as unresponsive and the Operationally Responsive Space Office was created in 2007 to address this for the military. The intent of this course project is to use an educational research approach to develop a future architecture that will make space responsive in 2025. This paper evaluates the shortcomings that hinder quick and effective space-based support to the U.S. Military and Intelligence Community. The current space community is fragmented, preventing quick, unified decisions, and does not have the executive clout necessary to lead effectively. Our group's solution creates a Department of Space at the cabinet level. The Department of Space will unify the space community, promoting quicker decisions with one common and consistent vision. This change would enable unified plans and policies as well as allow one organization to prioritize all of the space programs. The responsive culture would facilitate other needed changes to Space Operations, Launch, and Acquisition.
The capability to rapidly deploy tactical satellites to meet a Joint Force Commander's immediate battlespace requirements is a well-documented joint capability need. Key U.S. strategic documentation cites the need for the capability to maintain persistent surveillance or an "unblinking eye" over battlespace and to rapidly reconstitute critical space capabilities to preserve situational awareness. The warfighter requires a tactical space-based deployment capability which employs a request to launch and operational deployment window of 90 to 120 days. This master's thesis executed two (2) major areas of work: apply, and reinforce the Operationally Responsive Space (ORS) mission tasks using the Joint Capabilities Integration Development System (JCIDS) process; then based on capability gap data generated from the process, analyze and define the capability gap of an ORS Adaptive Integration, Test and Logistics (IT & L) process for payload to bus deployment to meet the identified time scales. This document recommends engineering solutions and processes for the ORS IT & L "to-be" state for this warfighter capability. The ORS adaptive IT & L CONOPS developed as part of this work focuses on the Tactical Satellite Rapid Deployment System (TSRDS), which is an adaptive integration, test and logistics capability that enables rapid and effective payload to bus integration to meet a 90- to 120-day warfighter window.
Designing complex space systems that will deliver value in the presence of an uncertain future is difficult. As space system lifetimes are now measured in decades, the systems face increased risk from uncertain future contexts. Tradespace exploration increases the designer's system knowledge during conceptual design and with dynamic analysis can predict the system's behavior in many possible future contexts. Designing flexible systems will allow mitigation of risk from uncertain future contexts and the opportunity to deliver more value than anticipated by the designers. Flexibility is a dynamic property of a system that allows it to take advantage of emergent opportunity and to mitigate risk by enabling the system to respond to changing contexts in order to retain or increase usefulness to system stakeholders over time. Identifying flexible designs has traditionally been accomplished through subjective or heuristic methods, leading to a qualitative assessment of system flexibility. Objective and quantitative measures of flexibility are required for analysis of flexibility in tradespace exploration, as the number of designs is often too large for traditional qualitative approaches. Value Weighted Filtered Outdegree is introduced as a metric for identifying valuably flexible systems in tradespace studies in order to improve decision making during the conceptual design phase. Dynamic Multi-Attribute Tradespace Exploration (Dynamic MATE) is used as the basic tradespace exploration method for Value Weighted Filtered Outdegree. Dynamic MATE applies decision theory to computer simulation of thousands of system designs, across hundreds of unique future contexts. Epoch-Era Analysis is used to parameterize future contexts for dynamic analysis of the designs' performance. Although dominated in static analysis, flexible designs are valuable in the presence of changing contexts. The usefulness of Value Weighted Filtered Outdegree is established through application to the design of a satellite radar system. The metric was able to identify designs that are valuably flexible, and exclude designs that carry change capability that does not add value to the design across selected epochs. Showing another application of Value Weighted Filtered Outdegree, a comparison of flexibility for an Operationally Responsive Space architecture is conducted which highlights the advantages of a modular architecture in the presence of changing user requirements.
A design methodology for a new breed of launch vehicle capable of lofting small satellites to orbit is discussed. The growing need for such a rocket is great: the United States has no capabilities in place to quickly launch and reconstitute satellite constellations. A loss of just one satellite, natural or induced, could significantly degrade or entirely eliminate critical space-based assets which would need to be quickly replaced. Furthermore a rocket capable of meeting the requirements for operationally responsive space missions would be an ideal launch platform for small commercial satellites. The proposed architecture to alleviate this lack of an affordable dedicated small-satellite launch vehicle relies upon a combination of expendable medium-range military surplus solid rocket motor assets. The dissertation discusses in detail the current operational capabilities of these military boosters and provides an outline for necessary refurbishments required to successfully place a small payload in orbit. A custom 3DOF trajectory script is used to evaluate the performance of these designs. Concurrently, a parametric cost-mass-performance response surface methodology is employed as an optimization tool to minimize life cycle costs of the proposed vehicles. This optimization scheme is centered on reducing life cycle costs per payload mass delivered rather than raw performance increases. Lastly, a novel upper-stage engine configuration using Hydroxlammonium Nitrate (HAN) is introduced and experimentally static test fired to illustrate the inherent simplicity and high performance of this high density, nontoxic propellant. The motor was operated in both pulse and small duration tests using a newly developed proprietary mixture that is hypergolic with HAN upon contact. This new propellant is demonstrated as a favorable replacement for current space vehicles relying on the heritage use of hydrazine. The end result is a preliminary design of a vehicle built from demilitarized booster assets that complements, rather than replaces, traditional space launch vehicles. This dissertation proves that such capabilities exist and more importantly that the resulting architecture can serve as a viable platform for immediate and affordable access to low Earth orbit.

Space has become a critical part of the United States' warfighting capability and requires that future space systems become more responsive than the current systems of reusable and expendable launch vehicles. The US military relies on space assets for communication, navigation, and intelligence, surveillance, and reconnaissance. Our adversaries also recognize our reliance on space technology and are moving forward to deny us the use of those systems. To reduce our vulnerability to those threats, the United States must have the ability to responsively replace, supplement, and service its space assets. Although the development and operational use of systems that will support the evolving mission areas of space control and force application will be subject to political and fiscal leadership decisions, they will also require responsive spacelift capabilities and it is prudent to include those considerations in spacelift planning.
China is modernizing her military very rapidly and as her economy strengthens, the pace of military modernization is going to touch higher trajectories. This modernization would impact and alter the existing strategic environment in the world. In the region the impact will be more profound and will force her neighbors to rework their own military modernization programs, war fighting doctrines and their present position on relations with China and other regional powers and the US. Today, in addition to issues relating to human resource development, the biggest impediment is the availability of technology to develop new modern weapon systems and equipment. Will the drivers and trends of Chinese military modernization continue to be same or will there be changes? How will the modernization impact the PLA behavior, especially in its neighborhood? How will the neighbors react to this stupendous pace of militarization in the East Asia? What will be the role of Japan, Vietnam, India, Russia and US? How will china's restive periphery and PLA respond to the spread of Islamic fundamentalism? To correctly appreciate these changes, an in-depth understanding of Chinese military modernization is essential. This book is an effort in this direction and attempts to find some answers to the questions posed. The trends of modernization of the four services of the PLA have been analyzed and a capability suggested that the PLA is likely to have by 2025.
