Ridder Class Coastal Defence Ship

The Ridder Class Coastal Defence Ships were a class of six vessels designed and built beginning in 1929, intended to supplement the Ringerike Class vessels, further freeing up larger, more capable vessels for overseas duties, like their predecessors they were heavily armed for their size, featuring battleship grade weaponry. The class was ill-suited to use in the open seas due to their designs, this however was mitigated by their role only requiring them to operate in fairly shallow coastal waters as well as in and around the Fjords of Ringerike, two ships were also stationed with the Ingonian Fleet out of Sorland. Their construction was seen as an instrumental step towards the design and building of Ringerike's first true battleships.
