No, I have not looked into details of what exactly will be carried. I am honestly not sure the Navy has completely worked that out themselves yet. The one article I read indicated they're aware of all these different abilities, and are looking into additional ones. Besides weapons, they want various electronics/sensor packages. As we are currently lacking in ASW, I've read mention of "the idea at least" of a containerized ASW system. The Navy specified that any of these USV plaforms should be configurable for ASW. Tells me either they already have some systems, or they they have enough of an idea of them that they can give the designers info on what the platform needs to be able to configure that way. (The open sterns are said to be suited to towed arrays and VDS. You'll note that feature on at least the Saronic vessel. I've not looked up the rest.)

As you show, this new idea is widespread across the world's navies, and looks to be "the trend" of the near future. I have read several articles on China's containerized weapons and electronics systems (what the West knows of them which it will release publicly, at least, which is very vague.)

While the basics of what gets developed will not be secret...any company making them will happily announce them in trade circles...the Navy is likely to be vague and tight lipped on what they did get, and will certainly not broadcast what's operationally on any USV. One of the points of a containerized system is keeping everyone guessing what's in those containers. As it's all still new, I anticipate having to really dive into any search on container details. More of a project than I am into at this point. Stuff will emerge with time, and I am just as happy to not know what-all exactly we've put in those containers. I expect to be pleasantly surprised when some operation hits the news, and the press reports the Navy had a container that held equipment that made the operation successful.
