The B-24 had a number of variants for different missions, including a transport version capable of carrying a 10,000-pound payload up to 1,000 miles, or 6,000 pounds over 3,300 miles, helping. Several storage tanks were added, allowing a C-109 to carry 2,900gal (11,000L) of fuel weighing over 22,000 pounds (10,000kg). Hendrix did not permit smoking on his B-24, even though he was a smoker. The RAF found, as did the US, that global war increased the need for air transports and early-type bombers and seaplanes were converted or completed as cargo carriers and transports. The attack became disorganized after a navigational error which alerted the defenders and protracted the bomb run from the initial point. Mosquito Vs B17 #13342705. Long-range anti-submarine Liberators played an instrumental role in closing the Mid-Atlantic gap in the Battle of the Atlantic. It could manage an altitude of no more than 25,000ft (7600m), three or four thousand feet less than a B-17, but it flew 10-15mph (16-24 km/h) faster. A fully navalized design was seen as advantageous, and Consolidated Aircraft developed a purpose-built long-range patrol bomber in 1943, designated PB4Y-2. Compared to the B-17, it had a 6 feet (1.8m) larger wingspan but a lower wing area. (Later versions were fitted with a powered twin-.50 caliber (12.7mm) M2 Browning machine gun nose turret.) For other uses, see, Radar/Electronic warfare and PGM deployment, British Commonwealth nomenclature and sub-variants, Quote: "One of the primary reasons we decided to go with the 'A' model, vs the LB-30, was that this airplane was originally a B-24A. [22], Later in 1941, the first Liberators entered RAF service. It used differential braking and differential thrust for ground steering, which made taxiing difficult.[16]. In late June 1943, the three B-24 Liberator groups of the 8th Air Force were sent to North Africa on temporary duty with the 9th Air Force:[13] the 44th Bomb Group joined the 93rd and the 389th Bomb Groups. [19] When France fell in 1940, their aircraft were re-directed to the RAF. As early as 1938, the US Army Air Corps realized that if it went to war with another world power, the B-17 was be too small for long range bombing missions. Learn how we are strengthening the economies, industries and communities of our global partner nations. https://www.britannica.com/technology/B-17, GlobalSecurity.org - B-17 Flying Fortress. [40], Two squadrons of the South African Air Force (SAAF) also flew B-24s: 31 and 34 Squadrons under No 2 Wing SAAF based at Foggia, Italy. The Mark II was the first Liberator to be equipped with powered turrets, one plane having them installed before leaving San Diego, the remainder having them installed in the field: four Browning Boulton Paul A-type Mk IV with 600 rounds of .303 in the dorsal position; and a Boulton Paul E-type Mk II with 2200 rounds in the tail (later increased to 2500 rounds), supplemented by pairs of guns at the waist position, a single gun in the nose and another in the belly, for a total of fourteen guns. 120 Squadron RAF of Coastal Command with its handful of worn and modified early model Liberators supplied the only air cover for convoys in the Atlantic Gap, the Liberator being the only airplane with sufficient range. Though produced in smaller numbers than its partner the B-24 Liberator, the B-17, with superior high-altitude performance and greater resistance to battle damage, was the mainstay of the strategic bombing campaign. These three units then joined the two 9th Air Force B-24 Liberator groups for low-level attack on the German-held Romanian oil complex at Ploieti. Among the specialized squadrons were the 20th RS (RCM), 36th BS (RCM), 406th NLS, 63rd BS (SB) SeaHawks, 373rdBS (LAB) and 868th BS (SB) Snoopers. The B17 was a sedate aircraft and placed fewer demands on the flight deck crew. ", Winchester, Jim. On this Wikipedia the language links are at the top of the page across from the article title. No other American combat aircraft in history was produced on a larger scale. Liberators assigned to the RAF's Coastal Command in 1941, offensively to patrol against submarines in the eastern Atlantic Ocean, produced immediate results. Liberators were equipped with ASV Mk. Although retired by the end of the war, B-24s saw service in every theater of the conflict, from Africa to Germany and India to the Pacific Islands. Range: 1,850 miles Service Ceiling: 35,000 ft. B 24 - L IBERATOR The tail gunner's powered twin-gun turret was located at the end of the tail, behind the tailplane. The wing carried four supercharged Pratt & Whitney R-1830-35 Twin Wasp engines mounted in cowlings borrowed from the PBY Catalina (similar except for being oval in cross-section allowing for oil coolers mounted on each side of the engine) that turned 3-bladed variable-pitch propellers. [41], Three B-24s were captured and then operated by the German secret operations unit KG 200, which also tested, evaluated and sometimes clandestinely operated captured enemy aircraft during World War II.[42]. 4 x Wright Cyclone R-1820-97 radial piston engines developing 1,200 horsepower each driving three-bladed propeller units. At Willow Run, Ford produced half of 18,000 total B-24s alone. [56], Data from Quest for Performance,[57] Jane's Fighting aircraft of World War II,[58] General Dynamics aircraft and their predecessors[59], Aircraft of comparable role, configuration, and era. MEMORANDUM REPORT ON Boeing B-17E Airplane, A.C. No. The turret proved unsatisfactory and was soon replaced by a tunnel gun, which was itself omitted. Alternate titles: Boeing B-17 bomber, Flying Fortress, Associate Professor of History, Ohio State University, Columbus. Early versions proved to be more vulnerable to fighter attack than anticipated, but, by the time the B-17E version began to go into service shortly before the United States entered the war in 1941, the plane was equipped with turrets in the upper fuselage, belly, and tail. [citation needed]. A heavily loaded B-24 was difficult to fly at speeds of less than 160mph (260 km/h). In the China Burma India Theater (CBI), the C-87 was used to airlift cargo and fuel over the Hump (the Himalayas) from India to China. All armament and armor were removed and in some cases the tail turret. OPTIONAL: Maximum internal bombload of 7,983 kg (17,600 lb). Accuracy was to be achieved with the Norden bombsight, developed and fielded in great secrecy during the 1930s. Thornton's Statistical Control group demonstrated that Eighth Air force B-24s were taking lower casualties than B-17s because they were being given shorter, safer missions. ", https://web.archive.org/web/20090304014706/http://home.att.net/~jbaugher2/b24_27.html, "Indian Ocean New Guinea Kangaroo Service 19501946. Whole bomb formations had to drop their loads on the lead bombardiers command, and the inevitable small differences in timing and heading led to dispersed bomb patterns. BOAC also flew trans-Atlantic services and other various long-range air transportation routes. B-17, also called Flying Fortress, U.S. heavy bomber used during World War II. B-17G (In Addition to Above): 2 x 0.50 caliber Browning heavy machine guns in powered Bendix chin turret. Approximately 18,500 B-24s were produced across a number of versions, including over 4,600 manufactured by Ford. It edged out the B-17 on most performance criteria (speed, range, bombload). In comparison with its contemporaries, the B-24 was relatively difficult to fly and had poor low-speed performance; it also had a lower ceiling and was less robust than the Boeing B-17 Flying Fortress. LB-30As were assigned to transatlantic flights by RAF Ferry Command, between Canada and Prestwick, Scotland. Maximum payload is the difference between maximum zero-fuel Weight and operational empty weight . The Liberator originated from a United States Army Air Corps (USAAC) request in 1938 for Consolidated to produce the B-17 under license. Compared to the B-17, the proposed Model 32 had a shorter fuselage and 25% less wing area, but had a 6ft (1.8m) greater wingspan and a substantially larger carrying capacity, as well as a distinctive twin tail. Then came a firestorm of antiaircraft cannon shells, rockets and air-burst bombs, turning the skies into a hellish expanse of bullets, smoke, and flak. Helicopter widths include main rotor diameter. Subject: Acceptance Performance Tests Section: Flying Branch . For its actions on the Ploieti mission, the 44th was awarded its second Distinguished Unit Citation. It had turbocharged engines and increased fuel capacity. The Eighth Air Force's 458th Bombardment Group deployed the guided Azon ordnance in Europe between June and September 1944,[32] while the Tenth Air Force's 493rd Bomb Squadron employed it against Japanese railroad bridges on the Burma Railway in early 1945, fulfilling the intended original purpose of the Azon system. The success of the Mosquito as a pathfinder or tactical bomber is without challenge. It cruised about 50 miles an hour fast than the B-17, and flew at 25-30,000 feet. While RAF Bomber Command did not use B-24s as strategic bombers over mainland North West Europe, No. The top horizontal line represents the maximum payload. 540 ft/min [Diff.-49,460 feet] Boeing (McDonnell Douglas) F-15 Eagle Boeing B-17 Flying Fortress RoC (ft) 50,000 540 540. Because of this, Boeing began to work on pressurized long range bomber derivatives of the B-17. Fifteen of the 15th AF's 21 bombardment groups flew B-24s. The Liberators were later replaced by Avro Lancastrians. In total, a stunning 18,482 B-24s were produced to wage war against the Axis powers. Also like the B-17, it carried the Norden bombsight. Such were the production numbers it has been said that more aluminum, aircrew, and effort went into the B-24 than any other aircraft in history.[45]. In a joint venture between the Army Air Forces and the Office of Strategic Services (OSS) code-named Operation Carpetbagger, pilots and crews flew specially modified B-24Ds painted with a glossy black anti-searchlight paint to supply friendly underground forces throughout German-occupied Europe. It was known within the company as the Model 32, and some initial production aircraft were laid down as export models designated as various LB-30s, in the Land Bomber design category. In 1943, the model of Liberator considered by many the "definitive" version was introduced. Consequently, it was relatively easy for a poorly trained ground crew to load a C-87 with its center of gravity too far forward or aft, rendering the aircraft difficult to control due to inadequate or excessive longitudinal stability. Continued development work by Consolidated produced a handful of transitional B-24Cs with turbocharged instead of supercharged engines. The maximum take-off weight was slightly raised to 64,250 pounds, the maximum altitude lifted from 21,200 to 24,000 feet but the maximum speed was reduced to 263mph, largely as a result of increased drag.[9]. The book. This unit then was formalized as the 376th Bombardment Group, Heavy, and along with the 98th BG formed the nucleus of the IX Bomber Command of the Ninth Air Force, operating from Africa until absorbed into the Twelfth Air Force briefly, and then the Fifteenth Air Force, operating from Italy. The new Model 32 combined designer David R. Davis's wing, a high-efficiency airfoil design created by unorthodox means,[6] with the twin tail design from the Consolidated Model 31 flying boat, together on a new fuselage. From August 1943 until the end of the war in Europe, specially modified B-24Ds were used in classified missions. The planes service ceiling of 25,000 to 35,000 feet (7,500 to 10,500 metres), depending on the bomb load, put it above the worst of the German antiaircraft artillery, but, firepower notwithstanding, formations of B-17s proved unable to fight their way unescorted to targets deep inside Germany in the face of determined fighter opposition without incurring excessive losses. Liberators remained in service until 1948, when they were replaced by Avro Lincolns. As these aircraft normally returned to base once a formation had been established, a skeleton crew of two pilots, navigator, radio operator and one or two flare discharge operators were carried. Carpetbagger aircraft flew spies called "Joes" and commando groups prior to the Allied invasion of Europe on D-Day and afterward, and retrieved over 5,000 officers and enlisted men who had escaped capture after being shot down. Updates? Post was the only reporter assigned to a B-24-equipped group, the 44th Bomb Group. Other C-87 designations were the U.S. Navy designation RY and Lend Lease Liberator Cargo VII. As a result, the mechanically supercharged Pratt & Whitney R-1830-33s were replaced with the turbo-supercharged R-1830s. The RAF and later American patrols ranged from the east, based in Northern Ireland, Scotland, Iceland and beginning in mid-1943 from the Azores. This gave the B-24 a 35-percent higher wing loading. The Consolidated B-24 Liberator was an American heavy bomber that entered service in 1941. 3. Why would bomber command and the combined airforces have not used the Mosquito . This new fuselage was intentionally designed around twin bomb bays, each one being the same size and capacity of the B-17 bomb bays. The B-24 had a shoulder-mounted high aspect ratio Davis wing. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. An American B-24 Liberator in flight. Changes included the removal of all armament, provision for passenger seating, a revised cabin oxygen and heating system. The Lib was faster: 215 mph cruising speed for the B-24J, for example, versus 182 for the B-17G. Failing to do this meant that the B-24 flew slightly nose high, and it used more fuel. This meant climbing to about 500ft (150m) above cruise altitude, levelling off, achieving a cruise speed of 165-170mph (265-275 km/h), then descending to assigned altitude. The name "Liberator" was originally given to it by the RAF, and subsequently adopted by the USAAF as the official name for the Model 24. The first USAAF Liberators to carry out combat missions were 12 repossessed LB-30s deployed to Java with the 11th Bombardment Squadron (7th Bombardment Group) that flew their first combat mission in mid-January. II radar, which together with the Leigh light, gave them the ability to hunt U-boats by day and by night. This role was dangerous, especially after many U-boats were armed with extra anti-aircraft guns, some adopting the policy of staying on the surface to fight, rather than submerging and risking being sunk by aerial weapons such as rockets, gunfire, torpedoes and depth charges from the bombers. The XB-24 was then re-designated XB-24Bthese changes became standard on all B-24s built starting with the B-24C model.
