The Patriot missile complexes are not located around the Saudi Aramco factories and fields.

Axar.az reports citing Russian military expert Igor Pankratenko`s interview why Saudi Arabia's Patriot anti-aircraft missile complexes could not protect oil factories.

According to the expert, no one could have imagined that any attack toward Saudi Arabia would be in this direction:

"Moreover, unmanned aerial vehicles have maneuvered against a number of air defense systems.

Currently, Saudi Arabia is working to rebuild the situation, covering the most important infrastructure facilities and providing the necessary equipment. So I think the next attacks will not be so successful.

Comparing the S-400 with the Patriot the expert said the air defense complex was incapable against this attack:

“It is important to understand that neither the Patriot nor the S-300 nor the S-400 is a reliable defense mechanism against unmanned aerial vehicles."

Suffice it to remind you that the Russian systems have not been able to repel numerous attacks on the Syrian airbase Hmeymim. Therefore, S-400 could not save Saudi in this case. All we need right now is to take a number of important steps that the official Riyadh has already begun to implement.

Reliability of Patriot systems has been raised after two refineries owned by Saudi Arabia`s Saudi Aramco was hit. Some experts have claimed that the S-400 could repel these attacks.
