Expendable Launch Vehicles (ELVs) are characterized by their design for single-mission use, with components typically discarded or destroyed post-flight.
Answer: False
Expendable Launch Vehicles (ELVs) are designed for single use. Their components are not recovered or refurbished for subsequent missions; rather, they are expended during or after the mission.
