[1][unreliable source?] Info. In 1942, German air force chief Hermann Goering sketched out the requirement for the Amerika bomber—a strategic bomber capable of making 7,200-mile round-trip across the Atlantic. The combination of speed and reduced radar detection range would have made the Horten Amerika bomber very difficult to intercept. The Hortens were told to make a presentation for their Amerika Bomber design on Febuary 25, 1945 in Berlin. The Ho XVIII A was to be built mainly of wood and held together with a special carbon based glue. In fact, we know the flying jet bomber concept was viable because two years later, U.S. company Northrop test flew several prototype YB-49 flying wings with a range of nine thousand miles. Perhaps the Nazis mistakenly counted on a political effect. The diversion of valuable production resources to so many experimental technologies reflected an almost megalomaniacal tendency to believe science could compensate for Nazi Germany’s materially untenable position combatting the combined might of the Soviet Union, the United State and the United Kingdom. Thus it’s no surprise that the megalomaniacal villain of the film Captain America flies an apparent look-alike of the Horten jet bomber—on a mission to bomb New York City, of course. The Horten H.XVIII existed as a proposed jet-powered bomber for the German Luftwaffe during World War 2. Germany - Horten Aircraft Horten Ho XVIII B2 The B model of the H.XVIIIB was generally the same as the A model, except the four (down from six) engines and four-wheel retractable landing gear were now housed in underwing pods, and the three-man crew housed under a bubble canopy. Nonetheless, Horten proposed installing two belly-mounted thirty-millimeter autocannons for self-defense. EMW A6. H.XVIII's design is the source for the design of HYDRA's futuristic bomber aircraft in the movie Captain America: The First Avenger.[3]. However, given the abilities of the allies to decode Enigma machine messages, it is questionable whether such a mission could be planned or launched without their knowledge. But this not only incorrectly assessed American determination, but failed to appreciate the vast surplus capacity the United States had to build up its home defenses as well as wages war overseas. The Horten H.XVIII is a jet long-range bomber proposed design from Reimar Horten, based on the Horten Ho 229 Jet Fighter/Bomber, the H.XVIII used many of the same techniques. The Horten HoXVIII was a proposed German World War II intercontinental bomber that would have been based upon the Horten Ho 229 design. The Horten H.XVIII existed as a proposed jet-powered bomber for the German Luftwaffe during World War 2. It is uncertain if this overall design was directly dev… The fact that Berlin was making new plans to manufacture sophisticated intercontinental jet bombers even while columns of Allied tanks were advancing deep into Germany highlights how Nazism was not only an abhorrent ideology, but instilled a remarkable capacity for self-delusion. The proposed Ho XVIII B had a three man crew which sat upright in a bubble-type canopy near the apex of the wing. Though aerodynamically unstable due to their lack of tail stabilizers, flying wings produce very little drag, thus allowing for higher speeds. Horten Ho XVIII “Amerika Bomber.” Unique German aircraft that used the flying-wing concept. Soviet R-12b-Horten XVIIIa Fernbomber-A model of Exeption ! The aircraft was first proposed for the Amerika Bomber project and was personally reviewed by Hermann Göring, after review, the Horten brothers (with deep dissatisfaction) were forced to share design and construction of the aircraft with Junkers and Messerschmitt engineers, who wanted to add a single rudder fin as well as suggesting underwing pods to house the engines and landing gear. Originally to have had a span of 80m, it was to have been powered by six 448kW BMW pusher engines; range was estimated to be 6000km at a cruising speed of between 300 and 350km/h. German manufacturers built three different prototype heavy bombers to perform the task: the Junkers Ju-390, the Messerschmitt Me-264 and the Heinkel He-277. All you need to know about Horten Ho XVIII from a scale modeler perspective. Like the Ho 229, it would have possessed similar stealth characteristics, as well as a large fuel capacity for transatlantic missions. Expelled from the venture, the Horten Brothers were working with the Horten H.XVIII, which was also known as the Amerika Bomber. The Ho VIII was by far the largest of the Horten flying wings, and was designed as a commercial aircraft with accommodation for about 60 passengers. After other German firms failed to offer viable design concepts, in December 1944 the Horten brothers proposed their own novel idea: a flying wing powered by six Jumo 004B turbojets embedded on the back of its fuselage pod. There were two fixed main landing gear assemblies with two He S 011 turbojets mounted to each side. Resembling the Horten The B model of the H.XVIIIB was generally the same as the A model, except the four (down from six) engines and four-wheel retractable landing gear were now housed in underwing pods, and the three-man crew housed under a bubble … Though aerodynamically unstable due to … Soviet R-7 Sputnik, 1/72. The A model of the H.XVIII was a long, smooth blended wing. Horten Ho XVIII A. The Horten H.XIII was an experimental flying wing aircraft designed by the Horten brothers during World War II. Two large non-retractable underwing landing gear fixtures each slung two HeS 011 turbojets. The C model of the H.XVIII was based on the airframe of the H.XVIIIA with a huge tail. The Horten XVIIIA was in effect a spinoff of the Horten brother’s wooden Ho.229 flying-wing jet fighter. [attachment=99704:Horten H.XVIII.jpeg] In 1944 the RLM issued a requirement for an aircraft with a range of 11000 km (6835 miles) and a bomb load of 4000 kg (8818 lbs). The Horten H.XVIII was a proposed German World War II intercontinental bomber that would have been based upon the Horten Ho 229 design. There’s only one, chilling scenario in which the Amerika bomber would have had an impact: if Nazi Germany had completed development of its own nuclear weapons. The Horten H.XVIII was just an effort to satisfy the Germans wishes to manufacture an aircraft that could reach the United States. Nazi scientists also began developing intercontinental ballistic missiles, a manned suborbital rocketship called the Silbervogel, and piggy-back aircraft to execute inter-continental strikes without much to show for it. It was eventually rejected by the Horten brothers, as it was not a major improvement over the Ho XVIIIA. The Ho XVIII A was to be built mainly of wood and held together with a special carbon based glue. Expelled from the venture, the Horten Brothers were working with the Horten H.XVIII, which was also known as the Amerika Bomber. It had an MG 151 turret set in the middle rear of the wing and with six BMW 003turbojets slung under the wings; this was designed by Messerschmitt and Junkers engineers. However, even if the Nazis had somehow managed to build the Ho XVIII, their plan had a huge problem: there’s hardly any reason to believe a few raids on American cities would have had any useful military impact. The Horten H.XVIII was just an effort to satisfy the Germans wishes to manufacture an aircraft that could reach the United States. But its bigger sister – Horten XVIII (essentially, a scaled-up version of Ho 229) – could. Articles lacking reliable references from March 2014, Articles incorporating text from Wikipedia, Abandoned military aircraft projects of Germany, "Trivia: Captain America: The First Avenger (2011).". The Horten H.XVIII was a proposed German World War II intercontinental bomber that would have been based upon the Horten Ho 229 design. While prototypes of the Me 264 and Ju-390 were flown, none entered large-scale production. Based on data from the 229 design, experts at Northrop Grumman who built a replica 229 from the original plans in order to test its stealth capability have estimated the H.XVIII would have been able to (in ideal conditions) evade radar detection until it was within eight minutes of the east coast of the United States, making allied interception prior to payload delivery highly unlikely. Would anyone else like to see this as a German bomber? Like the Ho 229, it would have possessed similar stealth characteristics, as well as a large fuel capacity for transatlantic missions. Fernbomber Horten XVIIIa "Amerikabomber" Sharkit 1:72 7271 . It is uncertain if this overall design was directly developed by the Horten brothers or their manufacturer, as there is little surviving evidence of this proposed version. While there’s no written evidence showing the Nazis realized the Ho.229’s stealth potential during the war, testing has shown that Horten designs did have a modestly reduced radar cross section which would have decreased radar detection range. This, combined with successful Allied sabotage of heavy water facilities in Norway, led the Nazis to largely abandon their nuclear weapons ambitions as too expensive in 1942. Ho XVIII was a true intercontinental bomber to be powered by six Jumo 109-004 jet engines and could carry 4,000 kg of bombs at a cruise speed of 750 km/h (maximum speed was 820 km/h) at 15,000 m and hit targets located 11,000 km away on a one-way, practically suicidal mission. So how could a handful of raids by Nazi bombers meaningfully damage the huge U.S. war economy? To be fair, the materially ineffectual one-shot Doolittle raid of 1942 had caused Japan to redirect substantial resources from its offensive operations to home defense. The YB-49 spanned fifty-two meters wide and were powered by six turbojet engines embedded in the rear wings. Even as American troops poured over the Ludendorff Bridge at Remagen into Nazi Germany, Goering still wanted his Amerika bomber and approved the design in February 1945—but he wanted the brothers to build the jet by committee with engineers from Junkers and Messerschmitt. The A model of the H.XVIII was a long, smooth blended wing body. The Horten H.XVIII was a proposed German World War II intercontinental bomber that would have been based upon the Horten Ho 229 design. Its theoretical maximum speed of 528 miles per hour and service ceiling of 52,000 feet would have allowed it to fly higher and faster than the fastest piston-engine U.S. fighters of the time. Armament was considered unnecessary due to the expected high performance.[1]. The aircraft was to be built in huge concrete hangars and operate off long runways with construction due to start in autumn 1945, but the end of the war came with no progress made. This bomber was to … Lippish LP-12 Entwurf IV. The C model of the H.XVIII was based on the airframe of the H.XVIIIA with a huge tail. Its six turbojet engines were buried deep in the wing and the exhausts centered on the trailing end. The Horten H.XVIII was a proposed German World War II intercontinental bomber, designed by the Horten brothers. The Horten X was based upon the ongoing development of the Ho 229 flying wing and borrowed many of her inherent concepts including the lack of vertical tail surfaces, use of a pressurized cockpit and a jet-powered propulsion system. RuhrstahlKramer X4. HORTEN IIIf. Then many designs followed, based on Horten Brother’s ideas. I would be extremely happy to possess such a bomber, which would at last stuff the mouth of arrogance across the sea.”. Horten Ho XVIII. The Horten XVIIIA was in effect a spinoff of the Horten brother’s wooden Ho.229 flying-wing jet fighter. Its six jet engines were buried deep in the wing and the exhausts centered on the trailing end. [1], The B model of the H.XVIIIB was generally the same as the A model, except the four (down from six) engines and four-wheel retractable landing gear were now housed in underwing pods, and the three-man crew housed under a bubble canopy. Even then, however, such strategic attacks would not have halted the huge Allied armies already steamrolling the Wehrmacht in Europe, and would surely have precipitated nuclear retaliation by the United States. Just like Horten Ho-229 was in real life. EMW A9 and EMW A10. In the third book of British novel series Tunnels, by Roderick Gordon and Brian Williams, the H.XVIII as seen by part of New Germany Air Forces. Supposedly this new beast stored enough fuel in its wings for twenty-seven-hour round-trip treks to attack New York. After being dissatisfied with the committee designed Ho XVIII A, Reimar Horten redesigned the flying wing Amerika Bomber. Fortunately for the world, Nazi nuclear weapon research proved as unfocused as other Wunderwaffe projects, and Germany suffered a severe shortage of qualified physicists due to its racist policies and politicization of academia. The decentralized nature of German military research led to money being funneled into numerous competing projects instead of being efficiently prioritized for faster and more concrete results. Horten proposed six jet-engines Ho.XVIII flying-wing bomber that was the scaled-up Ho.IX design. The unbuilt H.XVIII represented, in many respects, a scaled-up version of the Horten … The Horten H.XVIII was a proposed German World War II intercontinental bomber, designed by the Horten brothers with pioneering features such as a flying wing configuration, turbojet engines and stealth characteristics. Horten H.XVIII - Wikipedia. Though the YB-49 didn’t enter service, it may have informed Northrop’s later development of the B-2 Spirit stealth bomber serving the U.S. Air Force today. It started with Ho-229 and its scaled-up proposal for Amerika Bomber – Horten H.XVIII.
