With over 18,000 aircraft built the Consolidated B-24 Liberator was produced
in even greater numbers than the other famous Second World War US bomber, the B-17 Flying Fortress.
The Liberator gained a distinguished war record with its operations in the
European, Pacific, African and Middle Eastern theaters. One of its main virtues
was a long operating range, which led to it being used also for other duties
including maritime patrol, antisubmarine work, reconnaissance, tanker, cargo and
personnel transport. Winston Churchill used one as his own transport aircraft.
The aircraft was originally designed to a United States Army Air Corps
requirement, and the prototype first flew on December 29,1939. Meanwhile, orders
for production aircraft had also been received from Great Britain and France,
who had tried desperately to build up and modernize their air forces for the war
which had been inevitable. However, the Liberator was not available to France by
the time of its capitulation, and French-ordered aircraft were diverted to
Britain.
Among the first Liberators to go into British service were six
used as transatlantic airliners with BOAC, while others went to Coastal Command
as patrol aircraft. As production in the States continued to expand, taking in
other manufacturers to help build the type, versions appeared with varying
armament and other differences. Liberators also found their way into the United
States Navy, the Royal Canadian Air Force and the armed forces of other
countries. In Europe, Bomber Command of the Royal Air Force concentrated mainly
on night bombing, while the United States Army Air Force operated mainly as a
day bombing force. On December 4,1942 US Liberators of the 9th Air Force
attacked Naples, recording their first raid on Italy, followed on July 19,1943
by the first raid on Rome by 270 Liberators and B-17 Flying Fortresses
of the USAAF casualties among the US day bombing forces were high, until the
perfection of formation flying and the support of long-range escort fighters.
This was well illustrated on August 17,1943 when 59 bombers were shot down while
attacking German ball-bearing factories, followed by 60 losses in a similar raid
in October. In March 1944 a large force of US Liberators and B-17 Flying Fortresses
attacked Berlin in daylight, the first of several such raids.
Incredibly, Liberators are recorded as having dropped over 630,000 tons
of bombs, while several thousand enemy aircraft fell to their guns. Some were
converted to carry the first US air-to-surface, radar-guided missile, the
Bat, and in April 1945 a Bat sank a Japanese naval destroyer.
After the war the Liberator continued to serve with the United States forces,
notably as an air rescue and weather reconnaissance aircraft with the Coast
Guard in the 1950s.
The first major external change of the B-24 lines
appeared on the twenty-sixth B-24G, when a new nose was designed to include a
power turret containing two .50-cal. guns for frontal protection. This most
effective forward arrangement increased the length to 67 feet 2 inches. The
Sperry ball turret became standard equipment on this and following models.

The B-24J Liberator was the variation produced in the largest quantity; a
total of 6,678 being constructed. It was so similar to the G and H models that
the latter were modified to become B-24Js by changing the autopilot and
bombsight. Armed with twin .50-cal. Brownings in the nose, upper, lower ball,
waist, and tail turrets, a total of 5,200 rounds of ammunition were carried. The
top speed of 290 mph was provided by four Pratt & Whitney
supercharged R-1830-65's with 1,200 hp each. Cruise was 215 mph and landing
speed was 95 mph with its Fowler flaps. Rate of climb was 1,025 feet per minute,
and service ceiling was 28,000 feet. Empty, the B-24J weighed 36,500 pounds and
grossed out at 56,000 pounds. Maximum range extended 3,700 miles. The Wing span
was 110 feet; wing area, 1,048 square feet; length, 67 feet 2 inches; height, 18
feet. Fuel capacity was 3,614 gallons.
The 1,667 B-24Ls and 2,593 B-24M
models varied only slightly in armament fixtures from their predecessors.
Several B-24s were used as transports under the Air Force designation of C-87
Liberator Express and a few became C-109 fuel tankers.

During 1943 the Allies increased their air attacks on key points in Hitler's Fortress Europe. In July British bombers turned Hamburg into an inferno. Dropping strips of tin foil to confuse the German radar system, the RAF dumped tons of incendiary and high-explosive bombs on the city. When the ten days of sustained raids were over, 70,000 people were dead, and Hamburg as a city had almost ceased to exist.

The Luftwaffe, however, was still able to inflict punishing losses on bombers that attacked strategic targets farther inland, beyond the range of escorting fighters. Almost one-third of the B-24s that made a low level raid on the oil refineries of Ploesti, Rumania in August were shot down. Sixty planes and their crews were lost on August 17 in raids against Schweinfurt and Regensburg, and in October, 148 bombers were lost in six days. The Combined Bomber Offensive was damaging Germany, but the cost was high.
