Modern nuclear submarines make their own oxygen as needed by electrolyzing sea water. The amount of oxygen carried by conventional submarines depends on the design and size of the particular submarine.
Yes, submarines can operate on the surface of the water. While they are primarily designed for underwater navigation, they can surface to recharge batteries, conduct operations, or allow crew members to breathe fresh air. When on the surface, submarines resemble conventional ships but retain the capability to dive and operate underwater as needed.
Eisenhower believed in stockpiling nuclear weapons and building the planes, missiles, and submarines needed to deliver them.

Eisenhower feared the the communists were an international conspiracy and sought world domination. He could see communist governments popping up all over and believed they must be contained. He believed in stockpiling nuclear weapons and building the planes,carriers, missiles, and submarines needed to deliver them.

Yes, North Korea has submarines
Submarines - poem - was created in 1917.
One of our Submarines was created in 1982.
Dallas Submarines was created in 1920.
Submarines control buoyancy primarily through the use of ballast tanks. By filling these tanks with water, the submarine increases its weight and sinks; conversely, by expelling water and replacing it with air, it decreases its weight and rises. This process allows submarines to adjust their depth and maintain neutral buoyancy as needed while underwater. Additionally, trim tanks can be used to fine-tune balance and stability.
Argentina had diesel-electric submarines while the British had nuclear-powered submarines.
