Presentation Outline
•Introduction
•Responsive Space, Historically Speaking
•“Spirally Develop” with A Focus
•Ground Rules for Study: Responsive Small Launch Vehicle
•Analysis Process
•Results – TSTO RSLV “Spiral 0-1”
•TSTO RSLV “Spiral 0-1” – Geometry Comparison
•“Spiral Development” from TSTO RSLV to HTO-RSLV
•Horizontal Take-Off (HTO) RSLV Concept Trades
•HTO RSLV Concept Comparison to Legacy Systems

Introduction
• AFSPC 001-01/02; Operationally Responsive Spacelift (ORS) and Prompt Global Strike
Mission Needs Statement Decomposition
• “.. capability to rapidly put spacecraft into orbit”
• “.. maneuver spacecraft to any point in earth-centered space”
• “.. logistically support them on orbit or return them to earth”
• “.. strike globally and rapidly high value difficult to defeat targets in a single or
multi-theater environment”
• Operationally Responsive Spacelift Needs Architectures that Support an Over-arching
Vision That Can Evolve
• “Spiral Development”, Merging of Technical Capability and Budget Realities
• A “Spiral Development” Approach for ORS Needs A Roadmap that Includes the
‘Present” and “the Possible..Technologies on the Shelf or at High Readiness”
• An Approach for Creating the “Roadmap” from an “Operationally Responsive”
Propulsion and Propellants Point of View
• Evolve to Higher Responsiveness By “Spiraling in” Upgrades to Propulsion,
Propellants, Propellant Management, and “Dispersed Launch” Capability
