At the start of the

, most combatants had little capability of flying at night, and little need to do so. The only targets that could be attacked with any possibility of being hit in limited visibility would be cities, an unthinkable target at the time. The general assumption of a quick war meant no need existed for strategic attacks. Things changed on 22 September and 8 October 1914, when the Royal Naval Air Service bombed the production line and hangars of the

After lack of success while using darts and small incendiary bombs to attack Zeppelins from above, ultimately a Lewis gun loaded with novel incendiary ammunition, was mounted at an angle of 45° to fire upwards, to attack the enemy from below. This technique proved to be very effective. After over a year of night Zeppelin raids, on the night of 2–3 September 1916, a BE2c flown by

Second World War

The war opened on 1 September 1939, and by this time, the RAF were well advanced with plans to build a radar – then called 'RDF' in Britain – equipped night-fighter fleet. The Airborne Interception Mk. II radar (AI Mk. II) was being fit experimentally to a small number of

opened in August 1940, the night fighter fleet was still in its infancy. Through this period, the RAF experimented with many other aircraft and interception methods in an effort to get a working night fighter force. One attempt to make up for the small number of working radars was to fit an AI to a Douglas Havoc bomber which also carried a searchlight in its nose. These Turbinlite aircraft were intended to find the targets and illuminate them with the searchlight, allowing

adapted for night flying to shoot them down visually. This proved almost impossible to arrange in practice, and the Cat Eye fighters had little luck during the closing months of 1940. The Turbinlite squadrons were disbanded in early 1943. By early 1941, the first examples of a production-quality radar, AI Mk. IV, were beginning to arrive. This coincided with the arrival of the Beaufighter, which offered significantly higher performance than the pre-war Blenheims; it was the highest performance aircraft capable of carrying the bulky early airborne interception radars used for night fighter operations, and quickly became invaluable as a night fighter.Moyes 1966, p. 5.Hastings 1979, p. 240. Over the next few months, more and more Beaufighters arrived and the success of the night fighters roughly doubled every month until May, when the ''Luftwaffe'' ended their bombing efforts. Although night bombing never ended, its intensity was greatly decreased, giving the RAF time to introduce the

Unlike in Britain, where the major targets lay only a few minutes' flight time from the coast, Germany was protected by large tracts of neutral territory that gave them long times to deal with intruding bombers. Instead of airborne radar, they relied on ground-based systems; the targets would first be picked up by radar assigned to a "cell", the radar would then direct a

s from below, where they were outside the bomber crew's field of view. Few bombers of that era carried defensive guns in the ventral position. An attack by a ''Schräge Musik''-equipped fighter was typically a complete surprise to the bomber crew, who would only realise that a fighter was close by when they came under fire. Particularly in the initial stage of operational use until early 1944, the sudden fire from below was often attributed to ground fire rather than a fighter. Rather than nighttime raids, the
