Can anyone tell me what a bow plane on a submarine is and what it does?

Question

in the book "run silent run deep"

Answer 1

Fins on either side of the bow of submarines which, when their attitude to the water was altered, would cause the sub to dive or climb or assist surfacing whilst underway.

Answer 2

bow planes look like the small wings on the back of an airplane. They can tilt up and down and are used to change the angle of the sub in the water to surface or dive.

Answer 3

It's just like a canard on an airplane. And modern submarines use them again, after decades of using sail-planes instead.

Answer 4

If you like "Run Silent, Run Deep" also read "Dust on the Sea" which is also by Edward Beach. Ned Beach was a submariner in WWII, and was on about 9 patrols in subs, and worked his way up to the command of a sub, but before he could sink a ship as the captain of his own sub, the war ended while he was en route to his patrol area.

In WWII subs, the bow planes were fins up near the bow of a sub, and they were used to determine the angle the sub kept. The stern planes determined the depth the sub kept. They were hydraulically operated, but could be manually operated with a lot of muscle.
