Submarines

When a submarine goes farther down in the water, the water pressure becomes greater. If the submarine goes to far, pipes can explode and let in water, or it can implode the submarine

Naval destroyers were a menace to submarines during WW 2 and difficult ships to sink. The speed of a destroyer and its ability to maneuver quickly in open water made them difficult targets for submarines. And their primary weapon of depth charges had the ability to sink any submarine. The use of sonar by destroyers also allowed them to track enemy submarines.

It depends entirely on the size of the boat, but 5 or 6 Main Ballast Tanks (port and starboard) and 4 or 5 Trim Tanks are the average.

As long as several years if an emergency (food supplies would be a problem then), but typically they are partially refueled every time they return to base. This may be every 2-6 months, depending on mission.

Personal submarines like the Triton are arguably the best for one or two passengers, but it depends on your lifestyle as to whether or not you consider it cheap or not - $2-$3 million.

Britain, USA, Germany and Italy used submarines during WW1

i think that its test and crush depths are still classified, but it is a safe bet that they can dive ~1000 ft. they normally operate way above that though.

The chain of command on a submarine typically starts with the commanding officer (CO), who holds the highest authority and is responsible for all operations and crew safety. Directly beneath the CO is the executive officer (XO), who assists with management and oversees day-to-day operations. Following the XO, department heads manage specific areas such as engineering, operations, and weapons, while crew members report to their respective supervisors within each department. This structured hierarchy ensures clear communication and efficient decision-making onboard.

Fairwater planes, also known as sail planes, are horizontal stabilizers located on the sail or conning tower of a submarine. They help control the submarine's depth and pitch during both submerged and surface operations. By adjusting the angle of these planes, submarines can efficiently ascend or descend in the water column, allowing for precise maneuvering. Their placement above the hull reduces drag and enhances hydrodynamic performance, making them effective for maintaining stability and control.

In the later years of the Cold War, under President Ronald Reagan, the U.S. Navy commissioned and built the Los Angeles-class submarines and designed and manufactured the Tomahawk cruise missile. Reagan's administration emphasized military buildup and modernization as part of its overall defense strategy. The Los Angeles-class submarines were pivotal for stealth and deterrence, while the Tomahawk missile enhanced the Navy's strike capabilities.

The Confederate submarine that was the first to sink an enemy ship was called the H.L. Hunley. It achieved this historic feat on February 17, 1864, by attacking the USS Housatonic off the coast of Charleston, South Carolina. The Hunley was a pioneering vessel in submarine warfare, although it ultimately sank shortly after its successful mission.

The main reason for the development of the submarine was to create a stealthy and effective platform for naval warfare, allowing forces to engage in surprise attacks and gather intelligence while remaining hidden beneath the surface. Submarines provide strategic advantages in both offensive and defensive operations, enabling nations to protect their maritime interests and enhance their military capabilities in contested areas. Additionally, advancements in technology have expanded their roles, including deterrence, surveillance, and special operations.

The captain of a submarine looks through a periscope, which allows them to see above the water while remaining submerged. This instrument consists of a series of mirrors and lenses that provide a view of the surface and the surrounding environment. By using the periscope, the captain can observe other ships, land features, and potential threats without exposing the submarine. Additionally, modern periscopes often incorporate advanced technology, including cameras and sensors, to enhance visibility and situational awareness.

Yes, a submarine can detect a black box underwater if it is within range and the conditions are favorable. Black boxes, or flight data recorders, emit signals that can be picked up by sonar systems used by submarines. However, the effectiveness of detection depends on various factors, including water depth, environmental conditions, and the submarine's sonar capabilities.

After someone dies in a submarine, the crew must follow specific protocols to manage the situation. The body is typically secured in a designated area to prevent contamination and maintain hygiene. Depending on the submarine's circumstances, such as depth and operational status, the crew may also need to consider how to notify command and possibly prepare for a recovery operation. Emotional support for the crew is also crucial, as the death of a shipmate can have a significant psychological impact.

The main parts of a submarine include the hull, which provides structural integrity and buoyancy; the sail, which houses navigation and sensor equipment; and the propulsion system, typically consisting of a nuclear reactor or diesel-electric systems. Additionally, submarines have ballast tanks for diving and surfacing, as well as control surfaces like rudders and fins for maneuverability. Inside, they are equipped with living quarters, a command center, and various systems for weapons and communication.

Submarines are designed to withstand the immense pressure of deep water through their strong, streamlined hulls made from high-strength materials like steel or titanium. Their shape allows them to distribute pressure evenly across the surface, preventing weak points. Additionally, submarines are engineered with internal structures that provide further support and integrity, ensuring they can operate safely at various depths without being crushed.
