This paper reviews the latest technological advancements and achievements in large ramair parachute development with a focus on the advantages provided by modular design and large ram-air parachute fault tolerance. The State of the art of autonomously guided large ram-air parafoil technology has been rapidly advanced. With these advancements it is now feasible to recover "high end" cargo such as rocket boosters by a single ram-air parachute rather than a cluster of conventional ballistic parachutes. A systems engineering approach, integrating robustly designed airborne guidance hardware, flight software, and ram air parachute technology combined with a robust flight test program has resulted in the development of a precision guided ram-air parachute delivery system that is capable of delivering large payloads precisely, softly and safely.
