- Armstrong Whitworth F.K.6, Sopwith L.R.T.Tr. and Vickers F.B.11 - all three put gunners into nacelles to provide wide fields of fire. The development of effective synchronisation gear which meant smaller fighters could be equally effective led to the end of development of the designs. As the fighters held the upper hand, raids were almost always carried out at night. During 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. During 1932, in the face of increasingly capable bomber aircraft, the British Prime Minister Stanley Baldwin surmised that interception efforts would inevitably not always succeed and that "the bomber will always get through". Furthermore, due to a lack of precision aiming capabilities, bombers were viewed as likely to attack urban environments in general; Baldwin noted that their primary purpose would be to "kill the enemy's women and children more rapidly than they killed yours". This state of affairs was considered distasteful and there was some consideration given to methods to allow bombing during the day. Two ideas became popular. The schnellbomber was a very fast aircraft that would simply fly right past the slower fighters due to the extra power of their twin-engine designs. This was demonstrated with great effect at multiple air races during the early 1930s, where light twins easily outperformed fighters. However, this situation only existed for a short period until more powerful aircraft engines emerged in the mid-1930s and once again a single-engine fighter could catch a twin-engine bomber. The other idea was the escort fighter that would attempt to break up attacks by the defense before they could reach the bombers. To have the desired range, the aircraft had to carry a large fuel load, and at the time this demanded a twin-engine aircraft. Such a design would not be able to maneuver with the single-engine day fighters, so attention was given to outright performance. World War II In Luftwaffe service Luftwaffe strategy was based mostly on daytime tactical bombing and put significant effort into the escort fighter concept before the outbreak of World War II. One of the principle outcomes of this attention was the Messerschmitt Bf 110 heavy fighter, which was widely produced. At the time of its introduction, the Bf 110 had been among the fastest production aircraft ever built, but as had occurred with the schnellbomber
