History

The K-gun Mark 9 was a prototype method for a depth charge launcher that was based on testing that began in World War I. The K-gun was an improved version of the Y-gun tested during World War I and adopted after the war ended. The K-gun Mark 6 had already replaced the Y-gun as the principal depth charge launcher in 1942. The Mark 6 used a design with an arbor fitted inside the projector to hold the depth charge in place and detached after both were launched as a unit overboard. In 1944, the United States Navy tested a slight upgrade to the K-gun the Mark 9. The most significant change was the inclusion of a built-in arbor and cradle. The cradle and arbor helped reduce weight. Tested on the USS Asheville, the program was canceled on the grounds that the weight reduction was marginal and not enough to justify replacing the existing K-gun Mark 6s.
