  2. ICD for Small Unit Space Transport and Insertion (Sustain) • Defines Capacity for JFC to Rapidly Transport Strategic Capabilities to Any Point on Globe • Addresses Rapid Employment of Tailored Expeditionary Forces from CONUS Including Use of National Security Space (NSS) Material Approaches • Increased Forward Presence • Evolutionary Improvements to Conventional Assault Support • Revolutionary Improvements to Terrestrial Aviation Capabilities • Space Insertion-Terrestrial Extraction • Space Insertion and Extraction with Refueling • Space Insertion and Extraction without Refueling Marine BGen Richard C Zilmer, Commander 29 Palms Training Command: “We briefed the Pentagon, Congress, USSOCOM, and the NSC and were never thrown out. 25-30 years from now the idea is to move a squad-sized unit of Marines to any place on Earth in less than two hours.”

  3. HOT EAGLE Incrementally Addresses Multiple Capabilities • Affordable, Reliable Spacelift • Global or Theater ISR • Space to Space ISR • Space Interdiction and Control • Force Application to Space • Force Application to Globe • Space Insertion of Personnel • Global Insertion of Personnel

  4. Multiple Options Evaluated • Space Insertion – Terrestrial Extraction • Forward Deployment Space Insertion and Extraction • Limited Range Space Insertion and Extraction Without Refueling • Near Space Revolutionary Improvements to Terrestrial Aviation Capabilities • Revolutionary Improvements to Terrestrial Aviation Capabilities Limited Range and Space Insertion and Extraction • Space Insertion and Extraction With Refueling • Space Insertion and Extraction Without Refueling

Team Extraction Approaches • Self Extraction – Hike Out • Leave crew capsule behind • Aircraft/Helicopter/Ship • Osprey / C-17 / C-130 • Leave crew capsule behind • Crew Capsule Pick Up Via Aircraft/Helicopter • CAV crew capsule separates from aeroshell and life support • Crew compartment pick-up via balloon cable and C-17 • Pick up crew capsule via C-17

  7. Bimese RLV Marine Space Transportation OptionsForward Deployment Space Insertion & Extraction • Use Bimese VTVL RLV • Bimese both stages same size • Upper stage has 24,000 fps ΔV ideal • Forward Deploy Upper Stage Only • Bimese can launch from CONUS, recover upper stage globally • Refuel and Launch Upper Stage • Upper stage inserts team • Arrival not stealthy • Recover Upper Stage • Team performs mission, moves to pick-up location • Upper Stage Picks Up Team • Out of Box Team Extraction Idea • Upper stage rejoins with C-17 which tows stage home • Stage is released for independent landing Single Bimese Stage Range

  8. Bimese RLV Marine Space Transportation OptionsForward Deployment Space Insertion & Extraction (cont) • Both Bimese Stages Could Forward Deploy • With identical stages, 2 CONUS launches forward deploy • Alternatively ship or aircraft could transport one stage • Stages Mated and Fueled at Forward Location • Upper stage inserts team • Recovers in theater • Portable LOX generation, JP-8 fuel, portable mating gear, bare pad launch possible with VTVL stages • Range Increases 50-100% Using Two Stages Bimese RLV Range Bimese Technology Implications High Mass Fraction Stages Required High AoA Reentries Useful for Stealthy Ingress Operability Technologies for Forward deployment

  9. Heavy Lift RLV Marine SpaceTransportation OptionGlobal Insertion & Limited Range Extraction without Refueling • Heavy-Lift Vehicle – Many Options • Launches Full-Propellant RLV Upper Stage • CONUS to Global Locations • Traditional modular approaches • Or Revolutionary technologies (DE, CCE, etc.) • RLV Uses Only Landing Propellant during Insertion • Landing propellant only 10-12% of propellant load • Limited Stealth • Insertion sonic boom can be minimized via high alpha reentry • Rocket engine ignition 2-3 min prior to landing not stealthy (but throttle is low) • Most propellant reserved for extraction • Integral DE fire support possible • RLV extracts team • Recovers in-theater • 500-1000 nm range Technology Implications Very High Mass Fraction Upper Stage Needed Close to Desired Marine Capability No CONUS Direct Return Possible Initially Mass Fraction Improvements could Enable Longer Range Returns

  10. Heavy Lift RLV Marine SpaceTransportation OptionGlobal Insertion & Limited Range Extraction without Refueling • Supports SOCOM Space Enabling Concept Requirement, 18 Mar 04 • UNS Marine Requirement, 13 Jul 02 • Stealthy, Survivable• Transport of 13 Troops & Equipment• Launch on Demand• Unrefueled transport• No overflight restrictions• VTVL One CONOPS HTV-3 Technology Multiple Boost Options Multiple Stage Options High AOA High Altitude Reentry over Target Minimizes Overflight & Noise Booster RTLS VTVL Egress Option Suborbital Hop First Order Assessment Insertion Very Viable – Egress Requires Very High Mass Fraction

  12. Team Extraction ApproachesPowered Options • Self Extraction – Powered • Limited Range of 300-1000 nm Initially • Insertion Vehicle Pick Up Via Aircraft • Boost to aircraft rendezvous – snag and tow • Boost to parasail glide – snag and tow • Deploy balloon from ground – snag and tow

  13. Upper Stage Landing Vehicle Release Marine Space Transportation OptionLimited Range Space Insertion & Extraction • RLV Upper Stage Releases Aerodynamic Descent, Parafoil Final Descent, Landing Vehicle • Upper Stage Recovers to Forward Location for Refueling • Parafoil Makes Final Descent and Landing • Stealthy insertion • Expendable landing vehicle • Upper Stage Extracts Team • Recovers in-theater • High L/D upper stage for extra range • ~1000 nm radius Technology Implications Very High Mass Fraction Upper Stage Needed High L/D Upper Stage Needed Very Lightweight Landing Vehicle Needed Landing Vehicle Gives Flexibility Aerodynamic Cross-Range Useful Stealthy Arrival Good Radius of Action Do Not Have to Defend Landing Vehicle

  18. Stepping Stones to Marine Capability • CAV Being Developed by DARPA Falcon Program and AFSPC • HCV Being Developed by DARPA Falcon Program, AFRL, and NASA (X-43, etc.) • RLV First Stage Being Developed by AFSPC/SMC/AFRL Advanced Reusable Spacelift (ARES) Program • RLV Upper Stage Program Could be DARPA/AFRL Hot Eagle Program Recommendation • Corps Support for Falcon, ARES, and Hot Eagle as Initial Stepping Stones to Capability to Place a Marine Squad Anywhere on the Globe in Two Hours Stepping Stone Programs All Funded ExceptHot Eagle Reusable Upper Stage Program

  19. Hot Eagle Recommendation • Biggest Common Technology Need for Upper Stages is High Mass Fraction Airframe / Structure • High Mass Fraction Stages Enable Bimese, Heavy-Lift, Hybrid Airbreathing and Eventually SSTO Concepts • DARPA/AFRL Hot Eagle RLV Upper Stage Program Should Emphasize High Mass Fraction • High Mass Fraction Gives Higher Performance, Larger Payload, Longer Extraction Range for Marine Applications • High Mass Fraction Allows Smaller and Less Expensive Upper Stages to Provide Same Capabilities as Larger, More Expensive Lower Mass Fraction Stages High Mass Fraction Benefits All Space Concepts
