The bomber will always get through was a phrase used by Stanley Baldwin in 1932, in the speech "A Fear for the Future" to the British Parliament.[1] The argument was that, regardless of air defences, sufficient bomber aircraft will survive to destroy cities.[2]:18–9
This was not hyperbole; at the time bombers had a slight performance advantage over fighters due to having multiple engines, so a successful interception would require careful planning in order to get fighters into a suitable defensive position location in front of the bombers. Before World War II and the invention of radar, detection systems were visual or auditory, which gave only a few minutes' warning, not nearly enough to arrange such a mission. This balance of force meant that bombs would be falling and there was little that could be done about it. For Britain, the answer was to concentrate on bomber production, primarily as a deterrent force.
Many theorists, especially in Britain, imagined that a future war would be won entirely by the destruction of the enemy's military and industrial capability from the air. The Italian general Giulio Douhet, author of The Command of the Air, was a seminal theorist of this school of thought.[3] H.G.Wells' pre-World War I novel The War in the Air concluded that aerial warfare could never be 'won' in such a manner as bombing, but in the 1930s, few disagreed with Baldwin's view. The most influential among those who disagreed was Hugh Dowding, who led RAF Fighter Command during the Battle of Britain.[2]:18 Others included Americans Major Claire Chennault, who argued against the so-called Bomber Mafia at the Air Corps Tactical School,[4][5] and Lieutenant Benjamin S. Kelsey, Fighter Projects Officer for the United States Army Air Corps.[6][7]
In recent years, the phrase has been resurrected to refer to suicide bombers and the inability of legislation or security to stop someone intent on blowing something up.[8][9][10]
