I want to know the answer to the following question:
When were the surface-to-air missile systems introduced?
All the background I'm provided with is that "The development of surface-to-air missiles began in Nazi Germany during the late World War II with missiles such as the Wasserfall, though no working system was deployed before the war's end, and represented new attempts to increase effectiveness of the anti-aircraft systems faced with growing threat from [bomber]s.". Is that enough to answer the question?
Answer: no
