Hi,

Torpedo depth could be set manually by the torpedo tubes operators, when torpedo loaded into the tube.

See this report:

paragraph:

16. The following external adjustment gears are provided:
Gyro angling in 1° steps.
Speed - High, medium and low.
Depth - 0-12 metres in 0.5 m. steps.
17. The gyro angling gear can be set by hand either at the gear box in rear of the tubes, or at angling gear on each tube, or by electric power from the director angle calculator.
