Form follows functions: the US doesn’t need these (much smaller) ships.
As I quoted earlier, Singapore took Swedish assistance on this and Sweden has been building and exporting similar small ships suited for the congested and contested waters of the Baltic. There are a lot of countries that have a niche in smaller vessels like these (Germany/Sweden/France/Italy etc.), who don’t mind providing technical assistance to others. The US is not a big player in that segment.
Thank you for your response. I appreciate your thoughts on it.
