Saudi Arabia has one of the biggest military budgets in the world. State purchased huge amount of western weapon systems, including the most advanced of them - US Patriot systems. It is even integrated into some sort of centralized Air defence system, also based on the western weapon systems.
Nevertheless, despite the fact that the Houthis announced such strike in August, and this infrastructure really matters for the kingdom, missile strike reached its goal.
Now, the US and Saudis have claimed that Iran backed this attack.
But no matter who really launched strike - does such a strike undermine those SAM systems' efficiency?
Were there any cases in which Saudis SAMs worked efficiently?
It is not the first failure of those SAMs in the middle-east, as I've also found this article. This also motivated me to ask such a question. Because each and every such failure questions efficiency of a weapon system as a whole (facts of success usings are also known, but it is interesting, what's the picture at whole).
Let's not be the car seller, who (to your question, why the car engine is not starting most of the time, as it should) claims: "But it does sometimes! Continue trying!". I do not undermine western SAMs - it works (maybe not as well as advertising says, but it does). Question is about Saudis SAM system efficiency.
