DURING THE PROPOSED PHASE II RESEARCH AND DEVELOPMENT EFFORT, THE PROJECT TEAM WILL COMPLETE THE INTEGRATION OF PREVIOUSLY DEMONSTRATED TECHNOLOGIES INTO AN UPPER STAGE PROPULSION SYSTEM FOR A SMALL LAUNCH VEHICLE (SLV). THE RESULTING STAGE WILL MEET LAUNCH VEHICLE REQUIREMENTS FOR MASS FRACTION AND SPECIFIC IMPULSE. THE PHASE II PROJECT WILL RESULT IN THE HOT-FIRE QUALIFICATION OF A FLIGHT-WEIGHT UPPER STAGE IN A STATIC TEST. THE PROPOSED PROJECT TEAM WILL DEVELOP A PLAN FOR A POTENTIAL FOLLOW-ON PHASE II FLIGHT DEMONSTRATION PROGRAM.
