United States
Although the United States of America contains a vast area of land, almost all of its allies and trading partners are overseas, and those interests require a powerful navy to support them.
The US Navy possessed some of the largest and most modern battleships in the world at the outbreak of World War Two, and despite losses during the Japanese attack on Pearl Harbor, was able to maintain a powerful presence in the Pacific. However, in the vast reaches of that ocean the battleship was no longer the king of battle. It was fortunate for the Americans that the handful of aircraft carriers then in service with the US Navy escaped destruction; given later events it is doubtful that a pure battleship force could have defeated the Imperial Japanese Navy.
The aircraft carrier became the main US naval asset during the war in the Pacific, which was very much a conflict between the air assets of opposing fleets. US carrier forces were hard-pressed early on but as the industrial might of the US was brought to bear, new carriers and air groups for them were deployed in such numbers that the enemy simply could not match their strength.
US naval forces were primarily engaged in the Pacific, but some capital ships and larger numbers of destroyers were deployed to the Atlantic theatre where their primary opponents were German U-boats.
Submarines:
The Gato-class of submarine was the first mass production US submarine class of the Second World War, forming the majority of the United States Navy's submarine fleet of the war. It was the Gato-class, and the successors of her design that were largely responsible for the disruption of the Japanese merchant fleet. Individual Gato-class vessels were given names of marine creatures, with the lead of her class named for a type of small catshark.
MTBs:
The Elco mounted four torpedo tubes which, combined with its speed, made it a serious threat to larger ships. The largest PT boat used by the US Navy, the Elco is also notable for future President Kennedy commanding one. Crews of these boats relied on their smaller size, speed and manoeuvrability - and darkness - to survive.
