A surface-to-air guided weapon system is the result of many years work by a large and diverse team and includes radars and fire control equipment as well as the actual missile. In the time available it is impossible to cover the whole weapon system and therefore no apology is made for concentrating on the development history of the missile itself. It must be remembered, however, that there are many parts of the Bloodhound weapon system, a major contribution to the whole, which will not be mentioned.
