The T2 tanker, or T2, was a class of oil tanker constructed and produced in large numbers in the United States during World War II. Only the T3 tankers were larger "navy oilers" of the period. Some 533 T2s were built between 1940 and the end of 1945. They were used to transport fuel oil, diesel fuel, gasoline and sometimes black oil-crude oil. Post war many T2s remained in use; like other hastily built World War II ships pressed into peacetime service, there were safety concerns. As was found during the war, the United States Coast Guard Marine Board of Investigation in 1952 stated that in cold weather the ships were prone to metal fatigue cracking, so were "belted" with steel straps. This occurred after two T2s, Pendleton and Fort Mercer, split in two off Cape Cod within hours of each other. Pendleton's sinking is memorialized in the 2016 film The Finest Hours. Engineering inquiries into the problem suggested the cause was poor welding techniques. It was found the steel was not well suited for the new wartime welding construction. The high sulfur content made the steel brittle and prone to metal fatigue at lower temperatures.
I-21 was a Japanese Type B1 submarine which saw service during World War II in the Imperial Japanese Navy. She displaced 1,950 tons and had a speed of 24 knots (44 km/h).

It sailed for a number of companies, and survived service in the First World War, only to be torpedoed and sunk by a German U-boat during the Second World War while sailing under the Mexican flag off the coast of Florida.

The Battle of the Caribbean refers to a naval campaign waged during World War II that was part of the Battle of the Atlantic, from 1941 to 1945. German U-boats and Italian submarines attempted to disrupt the Allied supply of oil and other material. They sank shipping in the Caribbean Sea and the Gulf of Mexico and attacked coastal targets in the Antilles. Improved Allied anti-submarine warfare eventually drove the Axis submarines out of the Caribbean region.
