Thewas a heavy bomber of from American production. The four-engined high-wing monoplane with twin vertical tail was next to the B-17 strategic bombers of the most important USAAF in the European theater of war. Manufacturer was the Consolidated Aircraft Corporation (1943: Consolidated Vultee Aircraft Co. andConvair).
Actually wanted the U.S. Army, that also produced the Consolidated B-17. However, Consolidated offered a machine with better services, to which the U.S. Marineordered a prototype in March 1939 with the condition that it should fly by the end of 1939. According to the tender of the United States Army Air , which called for an aircraft with even better performance than the B-17 Liberator which actually had a flying fortress to the greater range and payload, the service ceiling she could not reach, however. Thanks to this they had the Davis wing (wing by engineer David Davis with a large extension, less depth and high curvature). However, this airfoil also ensured that the slow flight characteristics and control left something to be desired. The B-24 was thus more difficult in the key for mutual fire protection close formation to fly than the B-17. The prototype XB-24 was based on the Consolidated B-32 and launched just in time for the scheduled appointment on 29 December 1939 on the Lindbergh Field with test pilot William Whetley first flight. Even before this ordered France in April 1939 175 machines that were delivered partly to Britain after the fall of France in June 1940. On 26 July 1940 called the Air Corps that the machine should be equipped with a turbocharger n and self-sealing tanks. The modified prototype and pre-series of seven YB-24 (the rest went directly to the United Kingdom) were used for further testing. This was followed by 36 B-24A-series pattern. The first application was made at the beginning of the Pacific against Japan in January 1942 in the attack on Sulawesi, the first major missions with B-24D in February 1943 in New Guinea.
The B-17 had a reputation battle damage far better to cope with than the B-24, and the fighter pilots of thekept the B-24 to shoot for relatively easy, particularly so since the B-24 tended easier to fire to fall as the B-17. The crews of the B-17 said with a touch of black humor, “they did not need an escort, as long as the B-24 are nearby – all hunters then pounced on the easier prey.”
An analysis of the loss suffered by the 8th Air Force in Europe bomber losses, however, shows that the loss rates of the B-24 was even slightly lower than that of the B-17. However, this result must be viewed in terms of the different operating conditions. Since the B-17 was used since August 1942 Europe and the beginning of time, no long-range escort fighter was available already many B-17 had up to that time at which the B-24 were used in combat, been shot down. In the later phase of the war, as the B-17 and B-24 were used at the same time and also long-range escort fighters were available, then more B-24 were shot down as a B-17. However, the “loss lead” the B-17 could not make up for the B-24.
In contrast to the B-17, the B-24 was significantly greater success in naval warfare used for antisubmarine warfare. This was mainly due to the higher compared to the B-17 range, which allowed it to operate over the mid-Atlantic and the Pacific. The Liberator was so instrumental in that as of May 1943, the “air hole” over the Atlantic, where the German U-boats were attacked most of carrier aircraft, could be completely closed and the Germanfleet suffered heavy losses (see U -Boat : January to May 1943). The B-24 was used in 1942 by the Coastal Command of the Royal Air Force and increasingly modernized technology over time, with radar devices were the aircraft over long distances locate submarines at night with the Leigh Light illuminate mentioned headlamp system and with water bombs, weapons and at the end of the war, even acoustically guided torpedo’s fight. Addition, there was also that the disadvantages compared to other bombers not as serious impact on the open sea, there was no danger of enemy fighters.
The B-24 was in large numbers (18,482) built than any other U.S. aircraft in. It was used both in the West and in the Pacific as a heavy bomber, a tank and maritime surveillance aircraft, as well as with the U.S. Navy under the designation PB4Y as submarine combat and reconnaissance aircraft. Particularly well known, the attack of 177 Liberators on the oil fields of Ploesti was the first August 1943, although 57 bombers were shot down and another damaged. Under the name Consolidated C-87, the pattern also found as a passenger and cargo aircraft use.
Under the designation F-7 is a reconnaissance version was delivered to the USAAF.
An improved version of the B-24 was the U.S. Navy as PB4Y-2 Privateer.
Assessment by crews
Captain Thomas Downey (448thGroup):
The B-24 was a little more difficult than to fly the B-17. The B-17 trimmed from you and they almost flew alone. Even when moving around a crew member of the B-24, had to retrim the aircraft continued. In the B-17 could actually perform a close formation flight, while one had to toil hard in the B-24 get added to it.
