Program Objectives
• Retire risks for a 2nd Generation Reusable Engine
• All technologies demonstrated in prototype
• Build to most challenging conditions
• Component operation (e.g combustion stability)
° Manufacturing capability (e.g. forgings)
• Enable commercial engine viability
• Work to requirements flowed to engine from program
• Loss of crew 1 in 10,000
• Loss of vehicle 1 in 1,000
• $1000/Ib to LEO
