They’re using diesels to charge. These are straight-up diesel-electric boats with a new battery technology, by my reading of this.
“They’re using diesels to charge.”
You know, I thought that can’t be right because they are usually at the top of the technology game. I can see having a diesel as a backup. (It’s a rare article where the reporter gets it mostly right.)
On the other hand, having been in the military industrial complex for thirty years, I have seen a lot of resistance to even proven newer technology.
