As the fighters held the upper hand, raids were almost always carried out at night. In the inter-war era, this led to the creation of dedicated night bomber designs that concentrated on solving the problem of long-range navigation at night. Lacking any way of tracking such aircraft over any distance, it was clear that "the bomber will always get through". These missions would also lack any ability to target point objects on the ground, and thus their goal would be to "kill more women and children more quickly than the enemy".
