Lambda is the name of a family of Japanese carrier rockets. It consisted of the types Lambda 2, Lambda 3, Lambda 3H, Lambda 4S, Lambda 4SC, and Lambda 4T developed jointly by Institute of Industrial Science of the University of Tokyo, Institute of Space and Astronautical Science of the University of Tokyo, and Prince Motor Company, which merged with Nissan in 1966. Lambda series rockets did not have guidance systems, as they had the potential to be converted for offensive military use, thus interpreted as a violation of Article 9 of the Japanese Constitution. However, future Japanese launch vehicles, such as the H-II, were allowed to have guidance systems.
