Carrier: A Guided Tour of an Aircraft Carrier

^BAKER

In February of 1944, now composed of four task groups with twelve fast carriers, Task Force 58, under Vice Admiral Marc Mitscher, raided the Japanese fleet anchorage at Truk, wrecking the base and driving the Imperial Fleet out of the Central Pacific. Mitscher, a crusty pioneer naval aviator, aided by his legendary chief of staff Captain Arleigh Burke, ran Task Force 58 like a well-oiled machine. By the end of May, preparations had been completed for an invasion of the Marianas Island group, just 1,500 nm/2,800 km from Tokyo (thus within range of the new B-29 heavy bombers). Since these islands were essential to the defense of the home islands, the Japanese had to fight for them. The largest carrier-versus-carrier fight of the war resulted.

As soon as the invasion forces of Admiral Spruance's 5th Fleet hit the beaches of Saipan in early June, the entire Japanese battle fleet sortied from their base in northern Borneo to counterattack. When they arrived on June 19th, the nine carriers of the revitalized Japanese carrier force (three large, three medium, and three light fleet carriers) got in the first strike, launching their planes against Task Force 58 (now with seven large and eight light fleet carriers). That was their final hurrah; for the Japanese strike simply fell apart against the radar-directed fighters and antiaircraft fire of the American task groups. Of the 326 Japanese planes launched against the American fleet, 220 were shot down. Not a single U.S. ship was sunk or seriously damaged.

The next day, the U.S. fleet found the Japanese carrier force and launched a counterstrike. Blasting through the surviving Japanese planes, they sank the carrier Hiyo and several vital fleet oilers, and damaged numerous other ships before returning to Task Force 58.[12] The next day, the decisively beaten Japanese force withdrew to Japan. So great were the losses to Japanese air crews that their carriers would never again sortie as a credible force. When the U.S. 3rd Fleet invaded the Philippines in October of 1944, the four Japanese carriers that took part in the Battle of Leyte Gulf were used purely as decoys, and sunk by air attacks from Task Force 34.

The Revolt of the Admirals, the USS United States (CV-58), and the Korean War

When Japan surrendered in September of 1945, the United States had over a hundred carriers in commission or being built. Within months, the Navy had been slashed to a fraction of its wartime peak. Only the newest and most capable carriers and other warships were retained in the tiny Navy that remained. Part of this massive force reduction was a consequence of the simple fact that the war had ended and the naval threat from the Axis nations had been eliminated. But that was not the only rationale for cutting the fleet and other conventional forces.

The major reason for the cut was the development of the atomic bomb. Specifically, the leadership of the new United States Air Force (USAF) had convinced the Truman Administration that their force of heavy bombers armed with the new nuclear weapons could enforce the peace, protect the interests of the United States, and do it without large conventional ground and naval forces. This was a debatable point, which events were soon to prove hugely wrong. But the immediate result was a mass of hostility that broke out between the Navy and USAF in the last years of the 1940's.

The hostility did not start then, however. It had its roots in the 1920's in the battles over airpower between the Navy and Brigadier General Billy Mitchell. Mitchell, an airpower zealot and visionary, was not an easy man to like. He had already fought a losing battle to convince Army leaders of the virtues of airpower. Meanwhile, the small corps of Army aviators saw the developing strength of Naval aviation, which some of them saw as taking funds and support that should have been theirs. To set right this (perceived) imbalance, Mitchell and his fliers (against orders) sank the captured German battleship Ostfriesland, an act that did not sit well with the Navy. In 1925, fed up with Mitchell's stings and barbs, his superiors brought him up before a court-martial, where Mitchell, ever unrepentant, stated that airpower made the navies of the world both obsolete and unnecessary. Not surprisingly, the Navy (and others) publicly defended themselves against these charges, and they did it so effectively that Mitchell's professional career was finished. Mitchell's supporters never forgot or forgave that. The result was a multi-decade blood feud.

The Navy/Air Force war reached its peak during the 1949 fight for new weapons appropriations. Then as now, new weapons systems were expensive. Then, as now, the Navy and the Air Force saw it as a zero-sum game: You win/I lose (or vice versa). Practically speaking, the fight was over whether the nation's defense would be built around the new B-36 long-range bomber (armed with the H-bomb), or a new fleet of large aircraft carriers (called supercarriers) armed with a new series of naval aircraft that could carry atomic weapons. There was only enough money in the defense budget for one of these systems, and the Navy lost. The first supercarrier, the USS United States (CV-58), was canceled by Secretary of Defense Louis Johnson just days after her keel had been laid at Newport News, Virginia.

Outraged, the Navy's leadership made their case for Naval aviation in a series of heated (some would say fiery) congressional hearings that called into question the capabilities of the B-36 and the handling of the matter by Secretary Johnson and the Air Force. Johnson did not accept this 'Revolt of the Admirals' patiently; the Navy's leadership suffered for their rebellion against him. Many top admirals were forcibly retired, and the Navy paid a high price in personnel and appropriations.[13] However, it did manage to win some fiscal support for modernization of older fleet carriers and development of new jet aircraft.

This turned out to be a godsend, for the fiscal frugality of the Truman Administration came to a crashing halt with the outbreak of the Korean War in 1950, which caught the U.S. and the world with their military pants down. Except for some Air Force units in Japan and a few of the surviving aircraft carriers and their escorts, there was little to stop the North Korean forces from overwhelming the South. Built around the USS Valley Forge (CV-45) and the British light carrier Triumph, Task Force 77 was sent by the United Nations to interdict the flow of North Korean supplies and men. Eventually, Task Force 77 grew to four Essex-class carriers, and would become a permanent fixture not only during the Korean Conflict, but also throughout the Cold War.

For the next three years, carrier-based fighter-bombers rained destruction on the forces of North Korea and (after they entered the conflict) the People's Republic of China. Korea was not a glamorous war. For the pilots and crews of the carriers and their escorts, it was a long, cold, drudgery-laden, never-ending fight in which victory always seemed distant. What glory there was went to the 'jet-jocks' flying their USAF F-86 Saber jets up into 'MiG Alley' to duel with the Korean, Chinese, and Russian pilots in their MiG- 15's. But for the Navy and Marine pilots on the carriers, Korea meant blasting the same bridges and railroads they had hit last week, and would hit again next week. Still, Korea answered any question of America's need for Naval aviation to protect its far-flung interests during the Cold War.

With the end of the Korean Conflict, and the inauguration of a new President, the answer took physical shape in the completion of the aircraft carrier development cycle. Within just a few years, the first of four new Forrestal-class (CV-59) supercarriers would be built, setting a model for every new American carrier built ever since. Despite improvements in every system imaginable (from nuclear power plants to radar-guided SAM systems), the Forrestals have defined the shape of U.S. carriers for almost forty years. Meanwhile, the development of aircraft like the F-4 Phantom II, E-1 Tracer, S-2 Tracker, and others, led to the present-day structure of American carrier air wings. And at the same time, the roles and missions of carriers and their battle groups-their moves as pieces on the Cold War chessboard-were fixed in the minds of the politicians that would use them. The model set by the Forrestal and her jet-powered air wing was an almost perfect mix for the Cold War. With some improvements in Naval architecture and aircraft design, it has stayed on and done a great job.

Critical Technologies: Getting On and Off the Boat

What things make carrier-based Naval aviation possible? Actually, a surprisingly few critical technologies set carrier and carrier-capable aircraft design apart from conventional ship and land-based aircraft designs. Most have to do with getting on and off of the ship, and being tough enough to do it over a period of decades.
