British air doctrine had long repeated that the bomber would get through, placing heavy weight on offensive air power. Late-1930s radar development made interception more practical and exposed the need for a defensive fighter system as well. The rapid sequence from the Gloster Gauntlet and Gladiator to the Hawker Hurricane and Supermarine Spitfire shows an accelerating institutional shift. Officials were adapting according to the priorities, training, and experience available to them rather than acting from malice or simple incompetence.
