Following incidents when flare guns were accidentally discharged inside the rear fuselage, some assembly (formation) ships had pyrotechnic guns fixed through the fuselage sides. The maximum takeoff weight was one of the highest of the period. Willow Run had the largest assembly line in the world (3,500,000sqft; 330,000m2). Additionally, the Liberator equipped a number of independent squadrons in a variety of special combat roles. 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. Several storage tanks were added, allowing a C-109 to carry 2,900gal (11,000L) of fuel weighing over 22,000 pounds (10,000kg). Lloyd H. Hughes, Maj. John L. Jerstad and Col. Addison E. Bakerwere killed in action. Naval B-24s were redesignated PB4Y-1, meaning the fourth patrol bomber design built by Consolidated Aircraft. Earlier in the war, both the Luftwaffe and the Royal Air Force had abandoned daylight bombing raids because neither could sustain the losses suffered. The B-24 advanced the use of electronic warfare and equipped Search Bomber (SB), Low Altitude (LAB) and Radar Counter Measure (RCM) squadrons in addition to high-altitude bombing. The tail gunner's powered twin-gun turret was located at the end of the tail, behind the tailplane. This model introduced self-sealing fuel tanks, a 2ft 7in (79cm) plug in the forward fuselage to create more space for crew members and, more vitally, ever more equipment such as ASV Mark II radar (anticipated early in the Liberator's development when Reuben Fleet told the engineering team he had a gut feeling the nose was too short). That would make the total payload capability 134,000 lbs.! 'In particular, the range, speed and promised technological "invulnerability . Due to its range, it proved useful in bombing operations in the Pacific, including the bombing of Japan. [15] The occasional need during a mission for crewmen to move from fore to aft within the B-24's fuselage over the narrow catwalk was a drawback shared with other bomber designs. The Norden consisted of a gyroscopically stabilized telescopic sight coupled to an electromechanical computer into which the bombardier fed inputs for altitude, atmospheric conditions, air speed, ground speed, and drift. 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. Initially, these aircraft were to be given USAAC serials 39681 to 39-687. The 44th destroyed both of its assigned targets, but lost 11 of its 37 bombers and their crews. The B-24D was the first mass-produced series. The Liberator originated from a United States Army Air Corps (USAAC) request in 1938 for Consolidated to produce the B-17 under license. Production of B-24s increased at an astonishing rate throughout 1942 and 1943. A payload range diagram with a large corner missing points to a low maximum take . After the Fall of France the French orders were in most cases transferred to the United Kingdom. 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. RAF Liberators were also operated as bombers from India by SEAC and would have been a part of Tiger Force if the war had continued. Also, most naval aircraft had an Erco ball turret installed in the nose position, replacing the glass nose and other styles of turret. Just fewer of them. A B-24 could reach 290 miles per hour and carry a 5,000-pound bomb load for 1,700 miles, giving it a longer range, greater speed, and a bigger payload than its B-17 cousin." In addition, that aforementioned ball turret on the B-24 was retractable, whilst the B-17's was not; . The B-24 variants made by each company differed slightly, so repair depots had to stock many different parts to support various models. The design was simple in concept but, nevertheless, advanced for its time. US-based Liberators entered combat service in 1942 when on 6 June, four LB-30s from Hawaii staging through Midway Island attempted an attack on Wake Island, but were unable to find it. This was the B-24's most costly mission. Let us know if you have suggestions to improve this article (requires login). Because of their special skills, they were called upon to fly fuel to General George Patton's army during the summer and early autumn of 1944 when it outran its fuel supply. Whereas the B-17 used 9-cylinder Wright R-1820 Cyclone engines, the Consolidated design used twin-row, 14-cylinder Pratt & Whitney R-1830 "Twin Wasp" radials of 1,000hp (750kW). All but the last turret were power-operated, and each mounted a pair of 0.50-calibre (12.7-mm) machine guns. Cruising speed: 170 mph. The B-17 had excellent flight characteristics and, unlike the B-24, was almost universally well regarded by those who flew it. Therefore, the B-24 is superior to the B-17. In addition, 73 Liberators of various models that had force-landed on European airfields were recovered and 30 of them were repaired and used by the 45th Bomber Aviation Division. [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 PLAAF had two B-24Ms captured from the Chinese Nationalists during the Chinese Civil War and operated until 1952. 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. Although only 287 C-87 and eight U.S. Navy RY variants were produced, they were still important in the Army Air Forces' airlift operations early in the war when aircraft with high-altitude, long-range heavy hauling abilities were in short supply. Additionally, the tail span was widened by 2ft (0.61m) and the pitot-static probes were relocated from the wings to the fuselage. 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]. A B-24 could reach 290 miles per hour and carry a 5,000-pound bomb load for 1,700 miles, giving it a longer range, greater speed and a bigger payload than its B-17 cousin. They write new content and verify and edit content received from contributors. B-17, also called Flying Fortress, U.S. heavy bomber used during World War II. 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. Subject: Acceptance Performance Tests Section: Flying Branch . This increased firepower made the B-17 a formidable opponent for enemy fighters, particularly when flying in tightly stacked defensive formations for mutual protection. It edged out the B-17 on most performance criteria (speed, range, bombload). The wing gave the Liberator a high cruise speed, long range and the ability to carry a heavy bomb load. The B17 was a sedate aircraft and placed fewer demands on the flight deck crew. The sole B-24 in Hawaii was destroyed by the Japanese attack on Pearl Harbor on 7 December 1941. MEMORANDUM REPORT ON Boeing B-17E Airplane, A.C. No. Consolidated incorporated innovative features such as a tricycle landing gear and Davis wing. Compared to the B-17, it had a 6 feet (1.8 m) larger wingspan but a lower wing area. The turbocharged engines were the reason for the flattened oval shape of the nacelles that distinguished all subsequent Liberator models. B-17s couldn't carry as heavy a payload as the B-24, nor fly as far or as fast. Also like the B-17, it carried the Norden bombsight. In time the B-24 would boast a long, tapered wing atop its fuselage, which allowed impressive long-range cruising capabilities. In addition, the small number of Liberators operated by No. In the event, the need to keep such tight defensive formations over Europe compromised the accuracy of the Norden bombsight, since individual bomb runs were not possible without breaking the formation. Please refer to the appropriate style manual or other sources if you have any questions. The pilot and co-pilot sat alongside each other in a well-glazed cockpit. The Liberators range proved invaluable in scouting and destroying German U-boats, creating safe passage for Allied transports and destroyers across Europe. 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. The first Liberators in British service were ex-USAAF YB-24s converted to Liberator GR Is (USAAF designation: LB-30A). . It carried a larger bomb load than the B-17, and. 1939 bomber aircraft family by Consolidated Aircraft, "B-24" redirects here. This wing was highly efficient allowing a relatively high airspeed and long range. Each of the B-24 factories was identified with a production code suffix: Consolidated/San Diego, CO; Consolidated/Fort Worth, CF; Ford/Willow Run, FO; North American, NT; and Douglas/Tulsa, DT. The Liberators were later replaced by Avro Lancastrians. II radar, which together with the Leigh light, gave them the ability to hunt U-boats by day and by night. The U.S. Army Air Corps awarded a contract for the prototype XB-24 in March 1939, with the requirement that one example should be ready before the end of the year. The Secret War, by Brian Johnson, Pen And Sword Military Classics, 1978. pp. The C-87A was a dedicated VIP series built in small quantity. (1978). ", "Michigan History: Willow Run and the Arsenal of Democracy. The conversion had a hinged cargo door at the nose eliminating transparent nose and large cargo doors installed in the waist area. The success of the Mosquito as a pathfinder or tactical bomber is without challenge. 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. Armed with no less than 13 0.50-calibre machine guns, including two in a new chin turret for defense against head-on attack, the B-17G fairly bristled with machine guns. 200 Flight played an important role in supporting covert operations conducted by the Allied Intelligence Bureau; and other Liberators were converted to VIP transports. Please direct all other inquiries to militaryfactory AT gmail.com. The attack became disorganized after a navigational error which alerted the defenders and protracted the bomb run from the initial point. Engines: Four Wright "Cyclone" R-1820s of 1,200 hp. The Liberators flew a shorter 3,077mi (4,952km) over-water route from Learmonth to an airfield northeast of Colombo, but they could make the flight in 17 hours with a 5,500 pounds (2,500kg) payload, whereas the Catalinas required 27 hours and had to carry so much auxiliary fuel that their payload was limited to only 1,000 pounds (450kg). By mid 1943 this was being pushed to 60,000lbs and eventually on to 64,000lbs. Mission. [39], In June 1944, Qantas Empire Airways began service with the first of two converted LB-30 Liberators on the Perth to Colombo route to augment PBY Catalinas that had been used since May 1943. 51820. Reply. The "Military Factory" name and MilitaryFactory.com logo are registered U.S. trademarks protected by all applicable domestic and international intellectual property laws. The bombsight was located below the turret. Your selected aircraft are compared in side-by-side arrangement below. The United States Army Air Forces (USAAF) took delivery of its first B-24As in mid-1941. [8], The B-24 had a shoulder-mounted high aspect ratio Davis wing. ea. The 859 BS was converted from day bombardment to these operations and then transferred to the 15th Air Force. The Liberators made a significant contribution to Allied victory in the Battle of the Atlantic against German U-boats. Books repeated highlight the fact that the Mosquito bomb load over long distance was equal to a B17 (approx 4,000lbs). Leutnant Heinz Knoke (who finished the war with 31 kills) shot down the Liberator. Other C-87 designations were the U.S. Navy designation RY and Lend Lease Liberator Cargo VII. It had been sent to the Central Pacific for a very long-range reconnaissance mission that was preempted by the Japanese attack. The bomber was intended from the outset to attack strategic targets by precision daylight bombing, penetrating deep into enemy territory by flying above the effective range of antiaircraft artillery. The waist gun hatches were provided with doors. The payloads for the B-52H and B-2 are usually given as about 70,000 lbs. [13] For some time, newspapers had been requesting permission for a reporter to go on one of the missions.

Liberators remained in service until 1948, when they were replaced by Avro Lincolns. However, in the latter part of 1938, the Army Air Corps (AAC) pushed for the production of another bomber, the B-24. Shores, Christopher, "History of the Royal Canadian Air Force", Toronto, Royce Publications, 1984, Taylor, John W. R. "Consolidated B-24/PB4 Y Liberator. 3. After initial testing, the XB-24 was found to be deficient in several areas. The C-87 was not always popular with the aircrews assigned to fly it. The B-24's controls were heavy, especially if the control rigging was not properly tensioned. The VLR Liberators sacrificed some armor and often gun turrets to save weight, while carrying extra aviation gasoline in their bomb-bay tanks. Crews flew with the bomb bay doors slightly open to dissipate potentially explosive fumes. Consolidated finished the prototype and had it ready for its first flight two days before the end of 1939. During the bomb run, the sight was slaved to the automatic pilot to guide the aircraft to the precise release point. Later D models were fitted with the retractable Sperry ball turret. In some groups an observer officer flew in the tail position to monitor the formation.
