direct fire and under armor plates" are not yet meeting performance threshold requirements and are overweight. Additional studies and testing will be required to mature these technologies in order to meet performance (threshold) requirements to reduce weight. Key design constraints have been initiated. They are limiting the availability of manufacturing sources and are delaying the collection of data required for prototype production. What manufacturing readiness level should you use to assess this scenario? a. MRL 2 b. MRL 3 c. MRL 5 d. MRL 8
