What just like gases water can also exert pressure. if there's a structural problem on a submarine the submarine is likely to be crushed as it descends?

Just like gases, water exerts pressure due to its weight, and this pressure increases with depth. As a submarine descends, the water pressure surrounding it intensifies, which can be fatal if there are structural weaknesses in the hull. If these weaknesses are not addressed, the immense pressure can cause the submarine to be crushed, compromising its integrity and safety. This is why submarines are designed to withstand significant underwater pressure.
