During World War II, a stoker in submarines was responsible for maintaining and operating the vessel's engines and boiler systems. They ensured that the submarine had enough steam power for propulsion and operations, managing fuel supplies and monitoring machinery for efficiency and safety. Additionally, stokers often worked in challenging and cramped conditions, contributing to the overall functioning of the submarine during missions. Their role was crucial for the submarine's performance and operational readiness.
Germany announced an unrestricted submarine warfare campaign during World War I in early 1917. This strategy aimed to cut off supplies to the Allies by targeting military and civilian ships without warning. The decision contributed to the United States entering the war, as American vessels were also affected by these attacks.
The Sussex Pledge was rescinded by Germany in early 1917 primarily due to the military pressure of World War I and the need for unrestricted submarine warfare to counteract the Allied blockade. Germany believed that resuming unrestricted submarine warfare would help them gain a decisive advantage by cutting off supplies to the Allies. This decision ultimately contributed to the United States entering the war, as unrestricted submarine attacks on American ships escalated tensions between the U.S. and Germany.
During world war 2, the immediate course of action for preventing Japan from getting supplies was to carry out submarine tours near the south. Ships that were believed to be carrying items meant to supply Japanese soldiers were often torpedoed down.
In return for ending unrestricted submarine warfare, Germany sought to have the United States agree to respect its interests in Europe and potentially negotiate a peace settlement that would favor Germany's territorial ambitions. Additionally, Germany hoped to limit American support for the Allies, particularly in terms of military supplies and financial aid. This was part of a broader strategy to shift the balance of power in Europe in favor of the Central Powers.
A nuclear powered submarine can remain submerged for as long as it has fuel rods and supplies for the crew.

The Philippines becomes a colony of the US.1899-1902 - The Philippines declares independence and starts the Philippine - American war (US wins).1907 - As a step toward independence, an elected Philippine assembly is convened.1916 - The US promises eventual independence.1935 - The Philippine Commonwealth is created.1942-1945 - Japanese occupation of the Philippines (after defeat, the US still supplied Philippine Guerrillas with supplies and support).1944-1945 - Allied forces finally liberate the Philippines.1946 - The Philippines is granted independence in the Treaty of Manila.America has helped us to not be overwhelmed by other countries and preserve our own homes where we grew in the Philippines.
Without breathing, the world record is 22min With air bottles (scuba diver) or in a submarine you can of course stay longer. In a submarine when you have enough supplies, you can stay virtually forever under water.
Submarines can pump sea water into or out of ballast tanks, if they wish to change their weight (of course, anything that enters or leaves a submarine will also change its weight - people, supplies, weapons, etc. - but if you just want to change the weight, the easiest way is to pump water into the submarine).
To cut Britain, Europe and Russia off from deliveries of badly needed supplies.

Sonar and depth charges, fuel for anti submarine frigates and destroyers.
The Electrical Officer reports to the Chief Engineer. They are responsible for the electrical systems of the submarine. That will include the power supplies, batteries, and internal communications.
A German submarine attacked and sank a cruise ship because it believed that it was carrying weapons to Britain. 128 Americans were killed on it. This was an immediate cause for America to stop sending supplies to Germany.

They expected the British would stop their attempts to free continental Europe from German control if it was difficult to receive supplies from abroad, particularly from the US.
