CHAPTER ONE
Before the Beginning
IN 1921 ITALIAN aviation visionary Giulio Douhet proclaimed, âAeronautics opened up to men a new field of action, the field of the air. In so doing it of necessity created a new battlefield; for wherever two men meet, conflict is inevitable.â
In that opening passage of Command of the Air, Douhet established the twin towers of his professional philosophy: evangelical aviation mated with bone-deep cynicism about human nature.
Douhet wasâand remainsâan intriguing character. Born in 1869, he became an artillery officer but early on grasped the violent promise of military aviation. As a technocratâhe studied science and engineeringâhe perceived the potential for aerial warfare almost as soon as there were Zeppelins, let alone airplanes. In 1912, a year after Italy committed aircraft against the Turks in Libya, he wrote Rules for the Use of Airplanes in War. It was among the first efforts to establish a doctrine for military aviation.
When the Great War in Europe erupted in August 1914, Douhet was a vigorous forty-five-year-old infantry colonel. Eagerly following aviation developments, he was primed and ready when Italy entered the fray against Austria-Hungary and Germany eight months later. Though not a pilot, he advocated building an aerial armada of 500 bombers capable of carpeting the enemy with explosives, presumably forcing capitulation without prolonged ground combat.
But Douhet was bitterly disappointed as a succession of Italian defeats and command incompetence spurred his sharpened pen and acerbic tongue. Certain that aviation technology could offset his nationâs embarrassing unpreparedness, he vented his spleen in all directions, haranguing anyone who would listen, and many who would not. Inevitably such sentiments breached the tolerance of officialdom, and in 1916 Douhet was imprisoned for, among other things, âissuing false news . . . and disturbing the public tranquility.â
Undeterred in his evangelism, Douhet wrote from his cell, while army commanders and government ministers remained targets for his acid ink as the war news deteriorated. Finally, in late 1917, Italyâs fortunes bottomed out with the disastrous Battle of Caporetto, which produced 300,000 Italian casualties. At that dismal point Douhet was released from prison and named director of the General Air Commissariat, responsible for coordinating Italyâs aviation plans and policies. However, it was too little too late. He found an ingrained bureaucracy unwilling to enact his plans, and he left in disgust in June 1918.
Following the war, the verdict of Douhetâs court-martial was reversed and, remarkably, he was promoted to general. However, by then he had lost faith in Italyâs government and military, and declined to return to duty.
After 1918, Douhet believed the material means of achieving his vision of airpower finally existed. His colleague Gianni Caproni had produced hundreds of large, capable bombers, some flown by Americans against targets in Austria-Hungary. Other nations also had made remarkable progress, including the firms of Vickers and Handley Page in Britain; Sikorsky in Russia; and Gotha and Friedrichshafen in Germany. Douhet was concerned that, having built an air weapon, after âthe war to end all warsâ Italy would neither maintain nor employ the machines as he envisioned. Consequently, he focused more on his writing, leading to publication of Command of the Air in 1921. Essentially, it advocated unrelenting bombing of enemy population and production centersâa two-prong attack on a nationâs moral and material means of resistance. Properly conducted, Douhet asserted, such a policy could win a quick decision and save millions of lives in the long run.
High on Douhetâs list of requirements was an independent air force, by 1919 a reality only in Britain. There, Douhetâs opposite number was a prewar pilot, Major General Sir Hugh Trenchard, who in 1918 had belatedly espoused strategic bombardment and established a highly capable force that raided far into Germany. Unlike Douhet, Trenchard had staying power, remaining as chief of the air staff for a decade after the war.
Trenchard had already seen the reality of heavy bombers in the Great War. Though Germanyâs Zeppelin raids on London and environs gained most of the attentionâthe long, sleek dirigibles made great news copyâthey proved too vulnerable to improved defenses. Instead, the kaiser had turned to an armada of Gothas and Riesen (giant) biplanes beginning in the spring of 1917. However, from 1915 to 1918 only some 300 tons of Teutonic ordnance fell on Britain, causing 1,400 deaths and nearly 5,000 other casualties. It represented barely two daysâ sanguinary bill at the front, but the psychological impact was enormous. The appearance of German bombers in English skies led to nearly doubling the size of the Royal Flying Corps, literally overnight. It became the Royal Air Force in April 1918.
Meanwhile, in the nexus of wartime alliances, a third airpower champion appeared. He was a French-born American, Lieutenant Colonel William L. Mitchell, known to friends and to history as Billy.
As one of the senior U.S. airmen in France in 1917, Mitchell met Trenchard and established a warm personal and professional relationship. Six years junior to the Briton, Mitchell had won his wings in 1916 and was avid in his support of aviation. Rising rapidly, he rocketed to brigadier general and directed the Allied air effort supporting the huge Saint-Mihiel offensive in September 1918. Deploying nearly 1,500 planes, Mitchell crafted a remarkably effective air-ground plan in an era when aircraft voice radio was nearly nonexistent.
In his eighteen months in Europe, Mitchell made a name for himself, and enemies as well. His fiery advocacy of aviation alienated many ground officers, and his perceived flamboyance riled some of his fellow airmen. Because America lacked a strategic bombing force, his early focus was necessarily limited to tactical airpower, but after returning to America he soon raised his sights and became a disciple of Giulio Douhet.
All three menâthe Italian, the Briton, and the Americanâfaced similar postwar problems. The greatest was public and even military indifference. Conventional wisdom held that there would be no more Great Wars, especially with the emergence of the League of Nations. Consequently, vastly reduced defense funding became the fiscal bone that army and navy dogs scrapped over. With military and naval hierarchies firmly established, the upstart airmen began at a decided disadvantage, even with Britainâs Royal Air Force and then Italyâs Regia Aeronautica becoming independent services in 1923.
Mitchell faced a greater challenge than Douhet and Trenchard, as America enjoyed a 3,000-mile separation from Europe, courtesy of the Atlantic Ocean. No nation in the Western Hemisphere posed a remotely serious threat to the United States, leaving congressmen and senators to ask (not unwisely) why they should appropriate scarce funds for more flying machines.
Mitchell turned the financial argument on its head, insisting that long-range bombers could defend Americaâs shores more efficiently than a two-ocean navy. In attempting to prove his point, he finagled a series of tests pitting bombers against obsolete U.S. and captured German warships off the Virginia coast in 1921. The Navy agreed, mainly out of curiosity as to how modern naval vessels would withstand aerial bombardment. Ironically (in light of later developments) Mitchell sought participation of Navy aircraft as well.
Billy Mitchell may have been an irritating gadfly, but he meant business. He readily agreed to conduct the tests under âwartime conditions,â though the target vessels were immobile. Having accepted the rules, he cheated like hell. Mitchell obtained one-ton bombs that could not easily be carried aloft, and restricted the range of any aircraft that bore them. Nevertheless, in their most spectacular test his airmen scored a major triumph by using their unconventional weapons against the âunsinkableâ battleship Ostfriesland. The 24,000-ton veteran of the Battle of Jutland survived the first dayâs tests with minor damage, but the next day Mitchell launched his heavyweights, British Handley Page 0/400s. They scored two hits and four near misses that ripped Ostfrieslandâs hull, sending her down in twenty-one minutes. The Navy was astonishedâand the Army leadership embarrassed. But Mitchellâs giant bombs sank other aged battleships in additional tests, even using huge 4,300-pound weapons.
The next year Mitchell met Douhet in Europe and was captured by the Italianâs fervor and the depth of Command of the Air. Mitchell had excerpts sent to colleagues, and got banished for his trouble. Dispatched to Hawaii and then to Asia, he literally took a page from Douhetâs book and spent his exile producing a tome of his own. The result was a 324-page treatise predicting war with Japan. Published in 1925, Winged Defense insisted that the mere threat of sustained aerial bombardment would cause a collapse of enemy willpower, and that battleships were becoming obsolete as aviation technology advanced. The fact that Mitchell reverted to colonel that year probably was no coincidence.
That was bad enough. But in September, one of Mitchellâs naval counterparts died unnecessarily, following orders from nonaviators. Sent into treacherous weather over Ohio, Commander Zachary Lansdowne perished with thirteen other crew members of the dirigible Shenandoah. Fliers were outraged that âpaddlefeetâ controlled airmenâs destinies. Many grumbled; Mitchell exploded. Calling a press conference, he publicly accused the leaders of the U.S. Army and Navy of professional incompetence and indicted the âalmost treasonable administration of the national defense.â The gauntlet had been dropped, and no one doubted that it would be retrieved and flung in the accuserâs face.
In a sensational six-week trial, Mitchell exploited his court-martial to gain a public forum for his views. He received sympathetic coverage in many newspapers but the outcome was a foregone conclusion. Undeniably guilty of insubordination, in December 1925 he was suspended from active duty for five years. Rather than live with the penalty, he resigned from the Army to continue his crusade as a civilian. He died in 1936, still insisting that Americaâs military future would be found in the sky.
Eventually Mitchell was proven wrong on many details but the concept of strategic bombardment outlived him. Almost before he was buried, the Army gave significant contracts to two leading aircraft manufacturers: Boeing in Seattle, Washington, and Douglas in El Segundo, California. Their commission was to build single examples of large, ocean-spanning bombers that could be flown and evaluated as prototypes of follow-on designs. In the words of a later generation, they were technology demonstrators.
First up was Boeingâs experimental XB-15. Successfully flown by test pilot Edmund T. Allen in 1937, it featured a 149-foot wingspan and 32.5-ton empty weight. Its four 850-horsepower radial engines were reliable but insufficient to achieve tactical speeds. Nevertheless, the giantâs purpose was to prove that a bomber could fly 5,000 miles, whatever the speed. Assuming a mission radius of 2,500 miles, the XB-15âs 152 mph cruising speed equaled 33.5 hours airborneâthe duration of Charles Lindberghâs solo flight from New York to Paris in 1927. Consequently, the ten-man crew required an automatic pilot, bunks, galley, and lavatory. With a 12,000-pound bomb load, the B-15âs maximum takeoff weight was 5,000 pounds greater than that of the B-17G in World War II.
The Douglas entry, the XB-19, suffered a lengthy gestation. It represented half a generation of advancement over the XB-15, with greater size and weight, and a nose wheel configuration. With costs soaring, in 1938 the company sought to cancel the contract but the Army believed the giant (212-foot wingspan) was worth procuring. When first flown in June 1941, it had already been overtaken by advancing technology. Douglas envisioned a full crew of sixteen, including nine gunners for eleven machine guns and two 37mm cannon. There were also provisions for a six-man relief crew, acknowledging the problem of crew fatigue on prolonged missions.
Douglas lost money hand over fist on the XB-19. Paid $1.4 million, the company eventually spent nearly three times as much to complete the contract. Nevertheless, the XB-19 proved the potential for huge piston-driven aircraft, as its wingspan was seventy feet more and its seventy-ton empty weight nearly twice that of the B-29 Superfortress. However, an omen of things to come involved the troublesome Wright R-3350 engines, which proved unworkable and were replaced by 2,600-horsepower Allisons. The lone B-19 was scrapped in 1949.
Meanwhile, the Army had proceeded with a truly practical design, Boeingâs classic B-17. Smaller and shorter-ranged than the XB-15 and -19, it nonetheless represented the world standard in heavy bombers when it lifted off Boeingâs Seattle runway in July 1935. Later christened the Flying Fortress, it was produced in large numbers (more than 12,700 through 1945) and, perhaps more than any other aircraft, came to embody American aviation in World War II.
Other designs also were aborning, notably Consolidatedâs B-24 Liberator, first flown in December 1939. Even more widely built than the B-17, the Liberator is destined to hold the all-time U.S. production record with some 18,400 for the Army, Navy, and Allied nations. Between them, the Fortress and Liberator accounted for more than 60 percent of the worldâs heavy bombers manufactured for World War II.
Producing some 31,000 multi-engine bombers was one thing; supporting and operating them was quite another. The man responsible for making it happen was a Mitchell disciple, General Henry H. Arnold, chief of the Armyâs aviation branch.
Unquestionably dedicated to bombardment aviation, âHapâ Arnold was yin to Mitchellâs yang. One of the Armyâs first two pilots in 1911, Arnold was a company manâa West Pointer in contrast to Mitchellâs rise from the ranks. But Arnold possessed vision, ability, and political skills. After overcoming the early taint of Mitchellâs approval, he rose to command the Air Corps in 1938, with few policy makers doubting the need for a strong, capable air force.
There had already been some progress. In 1925 Congress established the Morrow Board (under Dwight W. Morrow, later Charles Lindberghâs father-in-law) to study military aviation. Based on that survey, barely six months after Mitchellâs trial, the Air Corps Act of 1926 granted quasi-independent status to Army aviation, with representation on the general staff, and expanded the air branch.
Despite such institutional success, airpowerâs early high priests fared poorlyâGiulio Douhet having been imprisoned and Billy Mitchell being court-martialed. Of the big three, only Britainâs Trenchard survived professionally.
In Search of Doctrine
Meanwhile, the great debate about aerial bombardment continued in Europe. Trenchard in particular believed that aircraft were inherently offensive so they must be used in a policy of what he called ârelentless and incessant offensiveness.â But unlike Douhet, who advocated bombing enemy populations, the Briton wanted to target heavy industry because he believed that destroying the enemyâs war-making potential would erode civilian morale.
Meanwhile, the U.S. Army conducted a long search for a practical doctrine of strategic bombardment. Most of the work was conducted at the Air Corps Tactical School (ACTS) at Maxwell Field, Alabama. Between the world wars, ACTS was the closest thing to a U.S. air academy. It provided courses in leadership, command, and air doctrine and strategy, though some instructors and students recognized that until proven in combat, theory necessarily remained theoretical.
When the doctrinal search began in 1920, airmen acknowledged that aviation technology would not match airpower theory for many years. In truth, two decades passed before Douhetâs vision of long-range bombers delivering heavy loads became a reality. Consequently, in the first six years of discussion, ACTSâs focus narrowed on the primacy of bombardment over the other aviation branches, notably reconnaissance and observation, ground attack, and fighter. Experience in the Great War had conclusively proven the worth of aircraft in reconnaissance and directing artillery fire, the great killer of the Western Front. Only the Germans deployed dedicated ground attack units, but most combatant air arms used aircraft to support the infantry.
With the primacy of bombardment aviation accepted by 1926, the Maxwell theorists next evolved the concept of the self-defending bomber, which would not require fighter escort. ACTSâs second study period lasted until 1934, the dawning of the B-17 era. Though the early technological deficit was declining as more capable aircraft emerged, some important wrinkles remained to be ironed out. It is remarkable that so many knowledgeable practitioners (nearly all captains and majors) denigrated the fighter. With some exceptions, they convinced themselves that unescorted heavy bombers could not only survive but thrive in a modern air defense network. The school solution held that bombers would op...
