Given your knowledge of currently funded NASA and Air Force programs, what would be your recommended technology roadmap? What changes and/or additional long-term technology investments should begin within the next seven years? 2. What RLV technologies does your company feel are state-of-the-art and ready for full-scale development today relative to your understanding of NASA and Air Force RLV requirements? 3.

What options would you recommend to support airplane like operations for the Military Space Plane? When would these operational capabilities be available to be part of a test/development program? 13. Can we develop the launch and early orbit checkout processes, techniques, and procedures to support first or second revolution use of sensors and payloads? Does this require increased technology efforts? 14. What is your assessment of whether sensors and payloads can be developed that can be jointly used by UAVs and space to support the Global Strike Task Force concept? Which areas are the best candidates? When might these be available? 21
