Realised that most modern submarines (and some aircraft carriers) use nuclear power, but destroyers and frigates don’t. I don’t imagine it’s a size thing, so I’m not sure what else it could be.

That’s a good question that doesn’t have an obvious answer.
The largest container ships cost hundreds of millions to produce (plural) and operating costs exceed $100k per day. They also burn bunker fuel which is dirtier than diesel. All told, emissions from the global fleet of more than 5,000 container shipping rival that of the estimated 1.5 billion gasoline cars in operation on earth, combined.
A zero-carbon future would almost certainly have to include most of the larger commercial shipping vessels transitioning to nuclear power.
