Stern Planes on a submarine are similar to tail wings on a plane; they serve as trim control for the boat, i.e., allow for more precise depth control.
Fairwater or Bow planes are used primarily to get the boat to an ordered depth'; once there, both planesman (Helmsman and Planesman) use both sets of planes to maintain depth control.
For example, the diving planes might be used to get a boat to 150'; once there, if more precise control is requireed (say moving to 140' or 155') the stern planes would be used.
Stern planes can also be used to help a boat change depth while remaining level; the dive planes change depth, while the stern planes maintain the trim, or level, of the boat as it moves through the different depth changes.

What was the rudder's use or what was it used for?
A rudder is mounted on the stern of a boat and is used to steer. It can also be found on ships, planes, aircraft, and submarines.
Where there Tanks planes and submarines in world war 1?
No there were no tanks planes OR submarines in ww1. My friend Dennis ate them all.
How does a submarine adjust its depth?
This answer addresses the modern military submarines. There is a bit of variation on the theme, and a bit more when considering other types of boats. When submarines are submerged and underway, they are neutrally buoyant. The boat is set up this way so that minimal effort is required to control depth. (If the boat isn't sinking or trying to float to the surface, the operators can tend to other things.) With a boat submerged and properly trimmed, the planes are added to the rudder as the hydrodynamic surfaces. There are a couple of set-ups for planes. Boats have stern planes back aft. From there, some have bow planes up front, and some have planes on the superstructure, or sail (conning tower). A boat will have stern planes and bow planes, or it will have stern planes and sail planes. And the planes are used to control the depth. When the boat needs to surface or dive steeply, the bow and stern planes are used to "point" the boat in the desired direction. The angle that the vessel is moving through the water, the "bubble" of the boat, is changed. By tipping the bow planes up and the stern planes down, the boat can be pointed to the surface. Tipped oppositely, the boat heads down. For small changes in depth, both planes are eased in the same direction. Tip both up a bit, and the boat is pulled up through the water. And the boat's bubble isn't changed. Tip both planes down a bit, and the opposite effect results. The boat remains level while slowly changing depth. On the boats with the stern planes and the sail (or fairwater) planes, the depth is changed to dive or surface by using the stern planes in the same manner as in the boats that have both bow planes and stern planes. The fairwater or sail planes are not used. But for small changes of depth, the fairwater planes can be used by themselves. The fairwater planes are approximately amidships, and by tipping them up, the "down" force they impart "pushes the boat down" without changing the bubble of the boat. Make sense? The sail planes take advantage of the boat's neutral buoyancy. The force generated by the planes when they are used will act in a way that causes the boat to sink a bit more or rise a bit more without changing the bubble of the boat. It remains level while slowly changing depth. Use the links to look at pictures of boats and check out their plane configurations.
What did the Japanese travel in to bomb pearl harbor?
The Japanese bombed Pearl Harbor in bomber planes, fighter planes, submarines, and torpedo bombers. They also planned to use midget submarines but most didn't make it.
What weapons did Japan bring to Pearl Harbor?
Kate Torpedo Airplanes, Val Dive Bombers, Zero Fighter Planes, Mini-Submarines launched from Mother Submarines.
Why are the fins on the submarines are used?
They are actually called "planes" on a submarine and allow it to maneuver underwater. Horizontal "planes" allow the submarine to go up/down, vertical "planes" allow the submarine to go left/right.
What restrictions did the Treaty of Versailles set against Germany?
Germany were limited to the ammount of weapons (tanks, planes and submarines) they were allowed to have
What do militia means?
it encompasses all the manpower, the trucks,tanks,planes,ships,and submarines , ie anything to do with military power.
On planes in the back the things that help it steer what are they called?
thhe vertical plate at the stern of an aeroplane by which it is steered is a Rudder
How can a submarine stay submerged at certain depth underwater?
The military submarines maintain depth by use of the planes. As they move through the water, a little up or down "tilt" on the planes will keep the boat at the correct depth.
Describe Dwight Eisenhower's response to communism?
Eisenhower believed in stockpiling nuclear weapons and building the planes, missiles, and submarines needed to deliver them.
Why are planes better than cars?
Planes are not necessarily better than cars - they provide a totally different function.
