SMV and NASA Future-X
• NASA Research Announcement 8-22– ~$100M for Pathfinder and experiments– $20M congressional add for AF related activities
• AF Participated in Source Selection• Boeing Advanced Technology Vehicle (ATV) Chosen as X-37
– Very similar to AF Space Maneuver Vehicle (SMV)– Cooperative program between NASA and Boeing
• At 21 Dec 98 Flag Officer VTC, MGen Paul Promised AFRLwould Provide $16.1M S&T Funds to Make X-37 More Like SMV
– Solar array and power system for longer on-orbit time– Sensors and algorithms for rendezvous / proximity ops– Improved attitude / pointing system– Improved reentry maneuvering potential

Space Maneuver VehicleFamily Tree
X-40A• Dropped from Helicopter at Holloman AFB, NM 11 Aug 98• Based on Original 7000 lb Gross Weight Boeing ReflyTM Design• Will be Used During NASA/Boeing X-37 Program
– Dropped from B-52X-37
• NASA/Boeing Future-X Cooperative Program• Similar Outer Mold Line to 12000 lb SMV
– Modular for major component exchange– Over 35 experiments designed in
• AF Participating to Obtain Data for SMVX-40B
• AF “Second Tail Number”• Prototype SMV• More Capable than X-37
SMV• Operational Reusable Satellite and Upper Stage• Highly Operable 12000 lb Vehicle• Designed for Launch from ELV or SOV• Final Design not Determined

X-37 and X-40B Tentative Schedule
• CY 01 X-37 Roll-Out
• CY 02/3 X-37 Orbital Test Flight
• CY 02/3 X-40B Roll-Out
• CY 03/4 X-40B Orbital Test Flights
ReentryWorkshop_27Oct99_MS1-AMSP-SMV_KV p 11
X-37 Program Status
• Boeing Selection Announcement 8 Dec 98• Cooperative Agreement Negotiations Took Six Months
– Ownership /progress payments / indemnification– AF $16.1M– Test team / RTO / test sites
• Cooperative Agreement Finally Signed 14 Jul 99– Total value (Boeing + NASA + AF) $172.9M
• Kick-Off Meeting at Seal Beach, CA 4-5 Aug 99– Considerable technical work already accomplished– Schedule very compressed due to negotiation time lost– Target date for X-37 Shuttle mission late CY02
• Issues– No firm Shuttle mission yet– X-37 overweight (5800 lbs at landing incl 500 lb payload)– Weight gain has performance less than 6000 fps ∆∆∆∆V– ELV launch as fallback to Shuttle– No program funds allocated for actual ELV launch– Boeing told no Peacekeepers available (X-37 too heavy for Peacekeeper anyway)– Boeing will concentrate on Athena II and Delta II as ELV options
