A
night bomber
is a
bomber
aircraft
intended specifically for carrying out bombing missions at night. The term is now mostly of historical significance. Night bombing began in
World War I
and was widespread during
World War II
. A number of modern aircraft types are designed primarily for nighttime bombing, but
air forces
no longer refer to them as night bombers. More common terms today include
interdictor
and
strike fighter
, and such aircraft tend to have all-weather, day-or-night capabilities.
World War I

Strategic bombing
and night bombing were new in World War I, and there was much experimentation at night with aircraft such as the
Gotha G.IV
,
Gotha G.V
,
Handley Page Type O
, and various giant airplanes such as the
Riesenflugzeuge
and the
Sikorsky Ilya Muromets
. Navigation was difficult and precision was almost nonexistent but the psychological effect was strong. Night bombing worked as a terror weapon.
Prior to the introduction of
radar
, aircraft flying at night were nearly impossible to locate accurately enough for attack.
Acoustic location
was used to obtain preliminary rough coordinates.
Searchlights
scanning the sky could illuminate aircraft by chance and might track them long enough for
anti-aircraft artillery
to fire a few shots. Alternatively,
night fighters
were used for interception; they either cooperated with searchlights or tried to spot the bombers in the moonlight. The success rate of such defences were so low that it was widely believed that "
The bomber will always get through
", in the words of British Prime Minister
Stanley Baldwin
. Since World War I, the bomber had been seen as a terror weapon, and was later seen as a primary
strategic weapon
of
total war
. As Baldwin later said, their primary purpose was to "kill the enemy's women and children more rapidly than they killed yours".

As aircraft capabilities grew, so did their defensive firepower. By the mid-1930s, opinions were changing and the idea of daylight raids of aircraft providing their own self-defense came to the fore. In practice these aircraft proved entirely vulnerable to modern
fighter aircraft
and were rapidly returned to the night bombing role. However, these aircraft had not been designed for night navigation, and were generally lacking any effectiveness in these missions:
I don't think we realized at the time that our equipment wasn't really up to it. They'd forgotten to design or produce any navigation equipment, so the Wellington bomber, which was intended to be a day bomber, had to operate at night because it was so vulnerable during the day. It had virtually the same equipment that the Tiger Moth had, with one exception?the Wellington had a loop aerial. Here we were flying 500 or 600 miles over enemy territory, trying to locate a target in total blackout, often with cloud below us and a lot of industrial haze. It's not surprising that our bombers were 5, 10 miles away. There was no bomber stream. We were largely on our own, perhaps 10 or 14 aircraft at intervals.

The
USAAF
was the only force to press ahead with daylight strategic bombing raids during
World War II
. This proved as disastrous as the earlier
Royal Air Force
and
Luftwaffe
attempts, and had to be called off in late 1943. The arrival of the
P-51 Mustang
fighter in the "
bomber escort
" role allowed these missions to start again in 1944, and the fighter was so successful that the Luftwaffe fighter force was almost wiped out by the end of spring. Later on, the RAF also began to take part in daylight bombing raids aswell, cementing the defeat.
The USAAF also applied the same concept with the
bombing raids against Japan
in June 1944-early 1945 with daylight
precision bombing
against Japanese industrial facilities using
Boeing B-29 Superfortress
heavy bombers
. However, the results weren't successful because of the frequent
jetstream
blowing the
high explosives
off target, navigation problems,
anti-aircraft fire
, and
searchlights
, resulting in high losses among the B-29 crewmen. As a result, in February 1945, the USAAF switched to low-level
incendiary raids
against Japanese cities, most of them took place at night. The most devastating air raid in the war was the
firebombing of Tokyo
on the night of March 9?10, 1945, which destroyed 16 square miles, killed 100,000 Japanese, and made a million people homeless.
