Longmore's Disc was a disc that could be added to a British Torpedo Director to permit the crossing angle between the enemy and the torpedo bar to be read off directly.[Citation needed]

It was not a bad idea, but not the best idea. It was fitted on Torpedo Director Pattern 2380, but upon the creation of Robinson's Disc in 1914-15, it was to be replaced on these directors with that disc (which measured the angle between enemy heading and line of sight... the Inclination).[1]
