“The US Navy Faces a Major Challenge in Sustaining Combat Operations off the Coast of Iran”

"If Iran decides to fire 300 drones in a swarm attack on the carrier strike force, and each destroyer fires at least two air defense missiles at those drones, that would require 600 air defense missiles. And there is the problem… If each destroyer is carrying a load of Tomahawks, then they are only carrying a maximum of 100 interceptors. Not only will the destroyers not have enough interceptors to fend-off the attacking Iranian drones, they will deplete their missile stock.

The only way to reload these cells is that each destroyer must sail to a port equipped with cranes that are capable of reloading the VLS cells.The closest port — I am assuming that the port in Bahrain is not available because Iran will have closed the Strait of Hormuz — is in Diego Garcia, which is 3 to 4 days away if each USN ship is traveling at 25 knots.”

“In short, if Iran fires hundreds of missiles and drones at the US carrier task force the the US will not be able to sustain combat operations for more than a couple of days.”

The US Navy is in no way equipped to fight a long war against even Iran, let alone China. Their weaponry was never designed to meet the sheer rate and scale of munitions usage of modern industrialized warfare. The ships would rapidly become defenceless even against drones and supersonic missiles, let alone hypersonic missiles.
