Above and Below the Sea
December 7, 1941 was a pivotal point, not only because it brought the United States into World War II, but also because it signalled the end of the era of the battleship, and the new importance of aircraft and their transportation, the aircraft carrier. During the Pacific War, battleships and cruisers spent most of their time bombarding land positions, while the carriers were the stars of the key Battle of the Coral Sea, Battle of Midway, Battle of the Philippine Sea, and the climactic Battle of Leyte Gulf, largest naval battle in history.
Air power remained key to navies throughout the 20th century, moving to jets launched from ever-larger carriers, and augmented by cruisers armed with guided missiles and cruise missiles.
Just as important was the development of submarines to travel underneath the sea, at first for short dives, then later to be able to spend weeks or months underwater powered by a nuclear reactor. In both World Wars, submarines (U-boats in Germany) primarily exerted their power by sinking merchant ships using torpedoes, as well as other warships. In the 1950s the Cold War inspired the development of ballistic missile submarines, each one loaded with dozens of nuclear-armed missiles and with orders to launch them from sea should the other nation attack.
Three major naval conflicts took place in the second half of the 20th Century, of which two pitted fleet against fleet. One was the well known Falklands War, pitting Argentina against the United Kingdom. The other took place 11 years earlier in 1971. It was the third and last of the Indo-Pakistani Wars, in which Bangladesh gained independence from Pakistan with Indian assistance. The Falklands in particular showed the horrible vulnerability of modern ships to sea-skimming missiles like the Exocet. One hit from an Exocet sank HMS Sheffield, a modern anti-air warfare destroyer. Important lessons about ship design, damage control and ship construction materials were learnt from the conflict. The third major naval war took place between Iran and Iraq from 1980 to 1988. It did not feature any large fleet battles, but it featured attacks on merchant ships as routine for the first time since 1945. It also featured the largest surface action since WWII, when United States Navy ships went after Iranian oil rigs to punish the Iranians for their actions in the war. Iranian naval vessels intervened, and Operation Praying Mantis resulted. At the present time, large naval wars seem to be very rare affairs, with the main function of the modern navy being to exploit its control of the seaways to project power ashore. Power projection has been the primary naval feature of conflicts like the Korean War, Suez Crisis, Source | Copyright
