Who needs sailors anyway?

The crewing does not change as much as you would like to think. What changes is where they are when doing operational stuff. Also consider any USV, even if large mostly expendable, as there will be minimal chance to do Damage Control.

How does the crewing not change much? From the article:

Additional attributes include USVs built to commercial construction standards , automatic RF control with respect to EMCON mission requirements, interior space for additional hardware and up to 8 personnel, autonomous operation and high speeds at Sea State 4-5, software that allows for multiple USVs controlled simultaneously, and compliance with International Traffic in Arms Regulations (ITAR) to enable foreign military sales.

It's important to keep in mind that these are not replacements for crewed warships. They are single task vessels meant to augment the crewed fleet in a conflict...either to provide additional missiles or to be an additional point in the sensor web. They are to be used in mass and are meant to be attritable...damage control is not a priority.

I think that is easy to say for a vessel that is 10m and under, acceptable losses up to 30m, after that, people will be in shock when they lose a bigger vessel to something that was otherwise salvageable.

They are looking at Offshore Supply Vessels with a crew of 8 that they can take the crew off and have the vessel continue mission.

The vessel is a civilian vessel. Typically those particular boats would be used very hard in the civilian world. I doubt that civilian operators would operate much of a Fleet Maintenance Facility. If it got beaten up too much it would replaced.

And the Modules are 40 and 20 ft ISO Sea Cans with their own very separate maintenance needs.

They are available for something like 10 to 30 million and are available used for as little 1 or 2 million after a few years of service.

You have top tier civy companies, they operate the vessels to a certain standard and get rid of them when they reach a certain age, then they get picked up by a 2nd tier company that keeps all the necessary stuff working in good order and occasional deals with the other stuff, then it's sold again to the bottom feeders, who only fix something because the Inspector has detained the vessel.

It's really the sticker price that is important; you can need a fair bit of shockingly expensive stuff to properly fire something on target, and really doesn't take very long before someone stops looking at an uncrewed vessel as not a writeoff.

Also, as soon as it has weapons, and associated comms and crypto onboard with some kind of sensor package, physical security is a very real consideration. Last time I was supporting discussion of a uncrewed ship with weapons it very quickly went from uncrewed, to uncrewed with security, to uncrewed with security, with DC and support for the security... to fully crewed.

I think the key to successfully using Medium/Large USV's is to approach them as a single-purpose adjunct to crewed vessels not as unmanned warships in their own right. I don't think the technology is there yet. A "loyal wingman" at most but likely much more like a trailer towed (wirelessly) behind a crewed warship and acting simply as an extended magazine for the parent vessel. Weapon direction would come from the parent vessel.

You'd only be deploying these when there is a real expectation that conflict is imminent rather than having these deploying autonomously during peacetime so security would be the Task Group that the USV is deployed with.

Small USV's would either be treated more like a munition (like the Ukrainians have been using against the Russians in the Black Sea) or acting as additional sensor nodes. For uncrewed sensor nodes though I think my preference would be for UUV's over USV's because they are more difficult to detect/intercept making security less of an issue.

I agree, and think for a number of reasons, small, less capable drones with a crewed mothership is a lot more practical then 'optionally crewed' warships. Instead of relying on one or two big hits for a mission kill, which there are existing countermeasures for, a big swarm of smaller munitions, which would overwhelm existing defences may do the same thing. No one is going to get too spun up about something like a hammerhead with explosives the Ukranians are using (or a half dozen of them) running up against a target, but putting a warship close enough to use anti ship missiles is a big difference.

And for a lot of it, you don't even necessarily need to do much to restrict access to that area for things like supply tankers, or get people to respond by using a lot more assets for the same job (tying them up) to protect high value assets. Mining an area can have a similar area denial, but impacts all sides, so having some kind of more mobile, temporary option may be a lot more feasible.

I'd be quite happy if I never heard the term "optionally crewed warship" again. It makes the good idea fairies of the world want to take what could be a technically feasible and cost-effective technology (relatively simple USV as an emergency "magazine extension" or attritable sensor node) and turn it into an unaffordable, technically fragile uncrewed multi-mission corvette-type monstrosity.

It's such a stupid idea; the only things that maybe makes sense if having a bridge available for people to bring it in and out of harbour. I think that's what they are doing for some of the electric cargo ships, that run designated routes with remote monitoring/control (in coastal areas where they can have comms to talk to ships in the vicinity).

If you don't have people on board for extended periods, a lot of things that take up space and need maintenance go right out the window, and you only need enough HVAC capacity to keep equipment from overheating/freezing. on a DC side you can do things like run spaces in a hypoxic atmosphere so even if your electrical shorts and blows out or similar nothing will burn (unless you get a hole punched in the side). Means you would need some kind of procedure to ventilate things prior to doing work as they are a confined space, but if you know that and plan around it it's not a big deal.
