The fins help steer the submarine; making it be able to turn left or right.

It doesn't need fins to move forwards, but fins are used to control rolling from side to side
Stabilising fins prevent a side to side rolling motion.
what does the term stabilizing fin mean
If a submarine lacked fins, it would struggle with stability and maneuverability underwater. Fins, such as the stern and control surfaces, are crucial for controlling pitch, yaw, and roll, allowing the submarine to navigate effectively. Without them, the submarine would be more susceptible to unwanted movements and could find it difficult to maintain a steady course or ascend and descend properly. Overall, the absence of fins would significantly impair its operational capabilities.
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.
A submarine can submerge by filling ballast and trimmer tanks with sea water. The additional weight will take the submarine down. To resurface, the submarine will blow the sea water out of the tanks using compressed air. The air in the tanks make the submarine buoyant, so it rises and floats on the surface. Though a stationary submarine can submerge in this way, it usually submerges going forward and using diving plane (fins) to steepen the dive, so getting under the surface faster.
Well, darling, submarines need fins to help with stability and control underwater. Those fins act like the submarine's rudder, helping it steer smoothly through the depths. So, next time you see a submarine cruising along, just remember it's those fins keeping it on course.
There are a wide range of different fins available for scuba diving. Other than dive fins, these include fins such as snorkel fins, paddle fins and split fins.
Yes, the halibut does have fins. It has multiple fins.

Large fins are fins that are large, in size. They are the opposite of small fins, and they are somewhat larger than medium fins. They are just a bit smaller than XL fins.
