The '''Torpedo Director Pattern 1193''' was a British torpedo director used in early torpedo craft featuring a 60 degree arc.<br />
<br />
It was created sufficiently early that it was no longer used in any modern ships as of 1912.<ref>''Torpedo Drill Book, 1912'', p. 494.</ref><br />
<br />
If a Pattern 1193a existed, it was similar, but made stronger in its pivots and sighting bar.<ref>''Torpedo Drill Book, 1914'', p. 564.</ref> <br />
<br />
In 1903, they were enhanced by addition of a graduated sight bar which could help a user determine whether he was within range of his torpedo, but which required mathematical computation to determine the extreme firing range.<ref>''Annual Report of the Torpedo School, 1903'', Plate 5.</ref> <br />
<br />
It was sometimes called the "Right Ahead" director.<ref>''Handbook of Torpedo Control, 1916'', p. 16.</ref><br />
