but it rather depends on what they mean by "prolonged". I find the "just days" claim somewhat ott; weeks seems more likely.

The ship-borne anti-missile/drone munitions are relatively easier to restock compared to the huge Patriot/THAD things so while I hope it's true that they can deplete their number in order to decrease the defensive capabilities it feels like they have the logistics to resupply at sea, especially if they just put a big hole in the navy (10% of their ships depending, of course, on what [or if] they actually hit).
