Moscow seems to like the idea:
A Russian firm is marketing a version of the Klub cruise missile that can be carried in a 40 foot shipping container. The launcher and the missile have to slide out of the container before firing, thus limiting where it can be placed on a ship, particularly your typical container ship. But you could get two or three of these shipping container Klubs on most cargo ships, turning the vessel into warship.
Not a great warship, of course. But not every mission needs to be carried out by the best ships we can send.
