The French frigate "Languedoc" shot down two incoming drones, which were obviosuly a threat.
They were coming from Yemen... so the Red Sea is unfortunately becoming more and more dangerous for merchant shipping, which is going to cause great concern for the world economies.
Anyway, as US NAVY does acknowledge : "...
the drone shootdowns are an expensive endeavor. The video, produced by the crew of the destroyer USS Carney, shows the ship launching multiple SM-2 or Evolved Sea Sparrow missiles from its VLS cell launchers. Depending on purchase batch and missile type, these rounds are priced at about $1.0-2.1 million, about 50-100 times the price of a Shahed-136.
Well done to the "Marine Nationale", in any case.
