Yeah makes sense, if you already have metal ships carrying goods there is no need to make additional ships just for protection. I suppose there could be an economic advantage if the pykrete ships can be made significantly cheaper and faster than the cargo ships.

It makes me wonder why Ukraine is so successful in the black sea with their sea drones vs. the Russian navy? Why wouldn't Russia have ships or something else blocking their battleships at port? It seems Ukraine is able to sink everything with ease at the moment.
