It was known within the company as the Model 32, and a small number of early models were sold under the name LB-30, for Land Bomber. The B-24 was used in World War II by several Allied air forces and navies, and by every branch of the American armed forces during the war, attaining a distinguished war record with its operations in the Western European, Pacific, Mediterranean, and China-Burma-India Theaters.<br \/>\nOften compared with the better-known Boeing B-17 Flying Fortress, the B-24 was a more modern design with a higher top speed, greater range, and a heavier bomb load; however, it was also more difficult to fly, with heavy control forces and poor formation-flying characteristics. Popular opinion among aircrews and general staffs tended to favor the B-17&#8217;s rugged qualities above all other considerations in the European Theater.[3] The placement of the B-24&#8217;s fuel tanks throughout the upper fuselage and its lightweight construction, designed to increase range and optimize assembly line production, made the aircraft vulnerable to battle damage.[4] The B-24 was notorious among American aircrews for its tendency to catch fire. Moreover, its high fuselage-mounted &#8222;Davis wing&#8221; also meant it was dangerous to ditch or belly land, since the fuselage tended to break apart.[5] Nevertheless, the B-24 provided excellent service in a variety of roles thanks to its large payload and long range.<br \/>\nThe B-24&#8217;s most infamous mission was the low-level strike against the Ploie\u0219ti oil fields, in Romania on 1\u00a0August\u00a01943, which turned into a disaster because the enemy was underestimated, fully alerted and attackers disorganized.[5]<br \/>\nThe B-24 ended World War II as the most produced Allied heavy bomber in history, and the most produced American military aircraft at over 18,400 units, due largely to Henry Ford and the harnessing of American industry.[6] It still holds the distinction as the most-produced American military aircraft.<\/p>\n<h3>Development<\/h3>\n<p>The Liberator originated from a United States Army Air Corps (USAAC) request in 1938 for Consolidated to produce the B-17 under license. After company executives including President Reuben Fleet visited the Boeing factory in Seattle, Washington, Consolidated decided instead to submit a more modern design of its own.[7]<\/p>\n<h3>Design<\/h3>\n<p>The B-24&#8217;s spacious, slab-sided fuselage (which earned the aircraft the nickname &#8222;Flying Boxcar&#8221;)[15] was built around a central bomb bay with two compartments that could accommodate up to 8,000\u00a0lb (3,629\u00a0kg) of ordnance each. The bomb bay was divided into front and rear compartments and had a central catwalk just nine inches wide,[16] which was also the fuselage keel beam. A universal complaint arose over the extremely narrow catwalk. The aircraft was sometimes disparaged as &#8222;The Flying Coffin&#8221; because the only entry and exit from the bomber was in the rear and it was almost impossible for the flight crew and nose gunner to get from the flight deck to the rear when wearing parachutes. An unusual set of &#8222;roller-type&#8221; bomb bay doors, which operated very much like the movable enclosure of a rolltop desk, retracted into the fuselage, creating a minimum of aerodynamic drag to keep speed high over the target area.[17]<br \/>\nLike the B-17, the B-24 had an array of .50 caliber (12.7\u00a0mm) M2 Browning machine guns in the tail, belly, top, sides and nose to defend it from attacking enemy fighters. However, unlike the B-17, the ball turret could be retracted into the fuselage when not in use, a necessity given the low ground clearance of the fuselage. The ball turret first appeared on B-24Ds sometime in early 1943 but not before the early Ds had used tunnel guns and the Bendix remote controlled ventral turret, also used (unsuccessfully) on the initial B-17E examples and on some early B-25 Mitchell medium bombers. General use of the ball turrets by the U.S. would last until late July 1944 when performance gains outweighed the need for 360 degree belly defense. Bomber command Liberators generally dispensed with the belly turrets as unnecessary in areas where no enemy fighter presence would be found.<\/p>\n<h3>Prototypes<\/h3>\n<p>Consolidated finished the prototype, by then known as the XB-24, and had it ready for its first flight two days before the end of 1939. After initial testing, the XB-24 was found to be deficient in several areas. One major failure of the prototype was that it failed to meet the top speed requirements specified in the contract. As built, the XB-24 top speed was only 273\u00a0mph instead of the specified 311\u00a0mph. As a result, the mechanically supercharged Pratt &#038; Whitney R-1830-33s were replaced with the turbo-supercharged R-1830s. Additionally, the tail span was widened by 2 feet (0.61\u00a0m) and the pitot-static probes were relocated from the wings to the fuselage. The XB-24 was then redesigned XB-24B\u2014these changes became standard on all B-24&#8217;s built starting with the B-24C model.<br \/>\nThe USAAC initially ordered seven YB-24s under CAC contract # 12464 in April 1939, but like the prototype these aircraft were being built by hand and were not considered combat ready. The first six YB-24 were released for direct purchase under CAC contract # F-677 on 9 November 1940. These aircraft were redesignated LB-30A. The seventh aircraft was used by Consolidated and the USAAC to test armor installations as well as self-sealing fuel tanks. Initially, these aircraft were to be given USAAC serials 39-618 to 39-687. Due to delays with the actual purchase, however, the serial numbers were changed to 40-696 to 40-702. When the RAF purchased the first 6 YB-24 aircraft, the serial numbers were reassigned to a later block of B-24Ds.<br \/>\nThe RAF, like the USAAC, found the LB-30As unsuitable for combat and had them assigned to the transatlantic Ferry Service between Canada and Prestwick, Scotland. The aircraft were all modified in Montreal for non-combat use. Changes included the removal of all armaments, provision for passenger seating, and a revised cabin oxygen &#038; heating system.<\/p>\n<p><span style=\"font-size: 13px; line-height: 19px;\">\u00a0<\/span>\n<\/div>\n<p>[\/tab]<\/p>\n<p>[tab title=&#8221;Gallery&#8221;]<\/p>\n<div class=\"topPerson\"><a title=\"\" rel=\"prettyPhoto-img\"><img decoding=\"async\" class=\"alignleft size-thumbnail wp-image-373\" title=\"\" src=\"http:\/\/aviatie-mircea-cantacuzino.ro\/wp-content\/gallery\/b-24-libertador\/800px-b-24_liberators_in_formation_1980.jpg\" alt=\"\" width=\"200\" height=\"150\" \/><\/a><\/p>\n<p><strong>Consolidated B-24 Liberator<\/strong><br \/>\n<br \/>\nThe Consolidated B-24 Liberator was an American heavy bomber, designed by Consolidated Aircraft of San Diego, California\n<\/div>\n<p><span style=\"color: #ff0000;\">[nggallery id=7]<\/span>[\/tab]<\/p>\n<p>[tab title=&#8221;Pilots&#8221;]<\/p>\n<div class=\"topPerson\"><a title=\"\" rel=\"prettyPhoto-img\"><img decoding=\"async\" class=\"alignleft size-thumbnail wp-image-373\" title=\"\" src=\"http:\/\/aviatie-mircea-cantacuzino.ro\/wp-content\/gallery\/b-24-libertador\/800px-b-24_liberators_in_formation_1980.jpg\" alt=\"\" width=\"200\" height=\"150\" \/><\/a><\/p>\n<p><strong>Consolidated B-24 Liberator<\/strong><br \/>\n<br \/>\nThe Consolidated B-24 Liberator was an American heavy bomber, designed by Consolidated Aircraft of San Diego, California\n<\/div>\n<p>[recent_posts count=&#8221;100&#8243; cat=&#8221;32&#8243;][\/tab]<\/p>\n<p>[\/tabs]<\/p>","protected":false},"excerpt":{"rendered":"<p>[tabs] [tab title=&#8221;Brief&#8221;] Consolidated B-24 Liberator The Consolidated B-24 Liberator was an American heavy bomber, designed by Consolidated Aircraft of San Diego, California About Consolidated B-24 Liberator &#8211;\u00a0Source Wikipedia Role:\u00a0Heavy bomber Manufacturer: Consolidated Aircraft First flight:\u00a029 December 1939 Introduction:\u00a01941 Status: Retired\u00a01968, Indian Air Force Primary users: United States Army Air Forces, United States Navy, Royal [&hellip;]<\/p>","protected":false},"author":2,"featured_media":1755,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-6243","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/posts\/6243","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/comments?post=6243"}],"version-history":[{"count":0,"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/posts\/6243\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/media\/1755"}],"wp:attachment":[{"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/media?parent=6243"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/categories?post=6243"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aviatie-mircea-cantacuzino.ro\/en\/wp-json\/wp\/v2\/tags?post=6243"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
