The Torpedo Director Pattern 2380 was a British torpedo director similar to the Pattern 2390a, but larger and of improved construction.[2] It was a 60 degree sector model designed especially for light cruisers.[3]
By 1916 (at least), it had a Possible Shot Scale and inclination disc.[4]
The enemy bar pivot was much stronger than on the 2390a. A lettered disc provided on the 2380 to set enemy heading in relation to the torpedo bar was obsolete by or before 1916.
The 2380a differed by having the lettered disc removed in favor of an inclination disc and a Radiomir fore sight.[5]
By mid 1917, these were being altered to the deflection model. [6] [TO BE CONTINUED - TONE] todo: explain plate
