Factors influencing this timeline include design specifications, technological advancements, and the availability of materials and skilled labor. Additionally, military submarines often undergo extensive testing and trials, which can extend the overall timeframe.

Missiles are fired from submarines using a system called Vertical Launch System (VLS) or torpedo tubes. In VLS, missiles are housed in vertical silos and ejected using gas generated from a small charge, allowing for rapid launch. In the case of torpedo tubes, missiles are loaded into cylindrical tubes that are flooded with water to create pressure, forcing the missile out of the tube. Submarine crews carefully control the launch process to ensure accuracy and safety.

A submarine floats and sinks by adjusting its buoyancy through the use of ballast tanks. When the submarine wants to sink, it fills these tanks with water, increasing its weight and causing it to descend. To float, the submarine expels the water from the ballast tanks, replacing it with air, which decreases its weight and allows it to rise. This ability to control buoyancy enables submarines to navigate at various depths in the water.

The temperature in submarines is typically maintained between 20°C to 25°C (68°F to 77°F) for the comfort of the crew. However, temperatures can vary based on operational conditions, equipment heat generation, and the submarine's depth. Effective climate control systems help to regulate the temperature and ensure a safe and comfortable environment for personnel during missions.

Exploring the deep ocean posed significant challenges due to extreme pressure, darkness, and temperature variations, making traditional exploration methods inadequate.
