This is, I believe, a very informative video. In addition there are some things that are worth noting,

• Deployed forces: Typically the US Navy has about a third of its fleet deployed and about one quarter actually underway. If you look at the list of ships that appears at time 5:45 to 6:30 you will see 23 destroyers involved in this operation. None of these destroyers are in the Pacific. The US navy has about 82 destroyers and cruisers. A third of 82 is 27.3, so there cannot be a lot of surface combatants deployed in the Pacific. This only accounts for two of the eleven aircraft carriers, Ford in the Eastern Med and Lincoln in the Arabian Sea. The George Washington carrier strike group is in their homeport in Japan, but that is the only carrier strike group and essentially the only destroyers assigned to 7th Fleet. There is not a lot left if say China attacked Taiwan.
• Weapons effect: This video contains a couple of interesting reports of weapons effect. The rapid sinking of the Iranian corvette (time 17:45) with very heavy loss of life was not unexpected considering the target was small and was probably not at general quarters. The effects of the attack on an LNG carrier using an unmanned surface vessel (USV) time 22:00) were I believe surprising–surprising the crew escaped and only one tank was blown out.
• Merchant vessel losses in the Persian Gulf: There are lot of merchant vessels “trapped” in the Persian Gulf including ships that are tied up, but losses of these ships has been surprisingly light. A small number of ships have successfully transited the Hormuz Strait without being attacked. Maybe Iranian targeting is not so good, but maybe they will regroup and get better.
