RAF Born: Royal Flying Corps Merges With Naval Air Service

Britain built something no nation had attempted before: an independent air force answering to neither army nor navy. The Royal Air Force came into existence on April 1, 1918, merging the Royal Flying Corps and the Royal Naval Air Service into a single branch with its own command structure, doctrine, and identity. Less than 15 years after the Wright brothers' first flight, air power had its own seat at the military table. The merger was born from crisis, not vision. German Gotha bombers had struck London in broad daylight during 1917, killing 162 people in a single June raid and triggering public panic. The existing arrangement, with army and navy each running separate air arms, had produced turf wars over aircraft production and competing strategies that left British skies poorly defended. Prime Minister David Lloyd George commissioned South African statesman Jan Smuts to study the problem. Smuts concluded that air power would eventually become the dominant form of warfare and recommended a unified force. The new RAF inherited roughly 150 squadrons and over 20,000 aircraft, making it the world's largest air force at its creation. Air Marshal Hugh Trenchard, appointed chief of air staff, fought through the interwar years to keep the RAF independent as the Army and Navy repeatedly tried to reclaim their air arms. Trenchard's doctrine of strategic bombing shaped RAF thinking for decades. The gamble paid its greatest dividends in 1940, when the RAF's Fighter Command won the Battle of Britain as a unified force with centralized radar-directed control. Had British air defense still been split between two services, coordinating the response to the Luftwaffe's assault would have been far more difficult. Winston Churchill's tribute to "the Few" was ultimately a vindication of the institutional choice made 22 years earlier. Every major military power eventually followed Britain's model, creating independent air forces of their own.
