Developed into Messerschmitt P.1107

The Messerschmitt Me 264 was a long-range strategic bomber developed during World War II for the German Luftwaffe as its main strategic bomber. The design was later selected as Messerschmitt's competitor in the Reichsluftfahrtministerium 's (the German Air Ministry) Amerikabomber (America Bomber) programme, for a strategic bomber capable of attacking New York City from bases in France or the Azores.

Contents

Three prototypes were built but production was abandoned to allow Messerschmitt to concentrate on fighter production and the Junkers Ju 390 was selected in its place. Development continued as a maritime reconnaissance aircraft instead.

Development

The origin of the Me 264 design came from Messerschmitt's long-range reconnaissance aircraft project, the P.1061, of the late 1930s. A variant on the P.1061 was the P.1062 of which three prototypes were built, with only two "engines" to the P.1061's four, but they were the more powerful Daimler-Benz DB 606 "power systems", each comprising a pair of DB 601 inverted V-12 engines. These were also used in the long-range Messerschmitt Me 261, itself originating as the Messerschmitt P.1064 design of 1937. The DB 606's later use in the Heinkel He 177A's airframe design resulted in derision by Reichsmarschall Hermann Göring as "welded-together engines" in August 1942, due to badly designed engine installations. In early 1941, six P.1061 prototypes were ordered from Messerschmitt, under the designation Me 264. This was later reduced to three prototypes.

The progress of these projects was slow but after Germany had declared war on the United States four days after the Pearl Harbor attack by Imperial Japan, the Reichsluftfahrtministerium (RLM) started the more serious Amerikabomber programme in the spring of 1942 for a very long range bomber, with the result that a larger, six-engine aircraft with a greater bomb load was called for. Proposals were put forward for the Junkers Ju 390, the Focke-Wulf Ta 400, a redesign of the Heinkel He 277 design (itself only receiving its RLM airframe number by February 1943 to give Heinkel an entry in the Amerikabomber program later in 1943), and a design study for an extended-wingspan six-engine Messerschmitt Me 264B. The need for six engines was prompted by the inability of Germany's aero-engine designers to create reliable powerplants of 2,000 PS (1,470 kW) and greater, thwarting efforts to do the same with four engines instead. As the similarly six-engined Junkers Ju 390 could use components already in use for the Ju 290 this design was chosen. The Me 264 was not abandoned as the Kriegsmarine (German navy) separately demanded a long-range maritime patrol and attack aircraft to replace the converted Fw 200 Condor in this role. [1] This was reinforced by an opinion given by then-Generalmajor Eccard Freiherr von Gablenz of the Wehrmacht Heer (German Army) in May 1942, who had been recruited by Generalfeldmarschall Erhard Milch to give his opinion on the suitability of the Me 264 for the Amerikabomber mission; Gablenz echoed the Kriegsmarine's later opinion. [2] The two pending prototypes were ordered to be completed as development prototypes for the Me 264A ultra long-range reconnaissance aircraft. [3]

Design

The Me 264 was an all-metal, high-wing, four-engine heavy bomber of classic construction. The fuselage was round in cross-section and had a cabin in a glazed nose, comprising a "stepless cockpit" with no separate windscreen section for the pilots, which was common for most later German bomber designs. A strikingly similar design was used for the B-29, of slightly earlier origin. The wing had a slightly swept leading edge and a straight trailing edge. The empennage had double tail fins. The undercarriage was a retractable tricycle gear with large-diameter wheels on the wing-mounted main gear.

The planned armament consisted of guns in remotely operated turrets and in positions on the sides of the fuselage. It carried very little armour and few guns as a means of increasing fuel capacity and range. The Me 264's first prototype was originally fitted with four Junkers Jumo 211 inverted V12 engines using the new Kraftei (or "power-egg") engine installation as standardized for the earlier Ju 88A Schnellbomber , but inadequate power from the Jumo 211 engines led to their replacement on the Me 264 V1 first prototype with four 1,700 PS (1,250 kW) BMW 801G engines. To provide comfort on the proposed long-range missions, the Me 264 featured bunk beds and a small galley complete with hot plates.

The first prototype, Me 264 V1, bearing a Stammkennzeichen (factory code) of RE+EN, was flown on 23 December 1942. It was powered at first by four Jumo 211J inline engines of 1,340 PS (986 kW) each. In late 1943, these were changed to the BMW 801G radials which delivered 1,750 PS (1,287 kW). Trials showed numerous minor faults and handling was found to be difficult. One of the drawbacks was the very high wing loading of the Me 264 in fully loaded conditions at some 356 kg/m2 (73 lb/sq ft). (Comparable contemporary aircraft had lower wing loadings: the B-29 had 337 kg/m2 (69 lb/sq ft), the redesigned He 277 334.6 kg/m2 (68.5 lb/sq ft) and the Ju 390 a much lower 209 kg/m2 (43 lb/sq ft).) The relatively high wing loading caused poor climb performance, loss of manoeuvrability, stability and high take-off and landing speeds. In addition, the first prototype was not fitted with weapons or armour, the weight of which would have caused worse performance.

The second prototype, Me 264 V2, was completed with armour around the engines, crew and gun positions, but defensive weapons and other vital operational equipment were never fitted. The never-completed Me 264 V3 was to have been fully armed and armoured.

In 1943, the Kriegsmarine withdrew their interest in the Me 264, in favour of the Ju 290 and the planned Ju 390. The Luftwaffe indicated a preference for the unbuilt Ta 400 and the Heinkel He 277 as Amerikabomber candidates in May 1943, based on their performance estimates. [4] In October 1943, Milch officially cancelled development work on the Me 264, so that Messerschmitt could concentrate on other projects, including development and production of the Me 262 jet fighter-bomber. No further payments for development work on the Me 264 were made to Messerschmitt AG.

Late in 1943, the second prototype, Me 264 V2, was destroyed in a bombing attack. [3] [5] On 18 July 1944, the first prototype, which had entered service with Transportstaffel 5, was damaged during an Allied bombing raid and was not repaired. The third prototype, which was unfinished, was destroyed during the same raid.

In April 1944, the competing Junkers project was cancelled. Consequently, on 23 September 1944, work on the Me 264 project was officially cancelled. Messerschmitt proposed a six-engine version, known as the Me 264/6m or Me 364, which also remained unbuilt.

The Junkers Ju 87, popularly known as the "Stuka", is a German dive bomber and ground-attack aircraft. Designed by Hermann Pohlmann, it first flew in 1935. The Ju 87 made its combat debut in 1937 with the Luftwaffe's Condor Legion during the Spanish Civil War of 1936–1939 and served the Axis in World War II from beginning to end (1939–1945).

The Heinkel He 111 is a German airliner and bomber designed by Siegfried and Walter Günter at Heinkel Flugzeugwerke in 1934. Through development, it was described as a "wolf in sheep's clothing". Due to restrictions placed on Germany after the First World War prohibiting bombers, it was presented solely as a civil airliner, although from conception the design was intended to provide the nascent Luftwaffe with a heavy bomber.

The Heinkel He 219 Uhu ("Eagle-Owl") is a night fighter that served with the German Luftwaffe in the later stages of World War II. A relatively sophisticated design, the He 219 possessed a variety of innovations, including Lichtenstein SN-2 advanced VHF-band intercept radar, also used on the Ju 88G and Bf 110G night fighters. It was also the first operational military aircraft to be equipped with ejection seats and the first operational German World War II-era aircraft with tricycle landing gear. Had the Uhu been available in quantity, it might have had a significant effect on the strategic night bombing offensive of the Royal Air Force; however, only 294 of all models were built by the end of the war and these saw only limited service. Ernst-Wilhelm Modrow was the leading night fighter ace on the He 219. Modrow was credited with 33 of his 34 night air victories on the type.

<i>Amerikabomber</i> Nazi German projects for long-range bomber aircraft

The Amerikabomber project was an initiative of the German Ministry of Aviation (Reichsluftfahrtministerium) to obtain a long-range strategic bomber for the Luftwaffe that would be capable of striking the United States from Germany, a round-trip distance of about 11,600 km (7,200 mi). The concept was raised as early as 1938, but advanced plans for such a long-range strategic bomber design did not begin to appear before Reichsmarschall Hermann Göring until early 1942. Various proposals were put forward, but these plans were all eventually abandoned as they were too expensive, too reliant on rapidly diminishing materiel and production capacity, and/or technically infeasible.

The Heinkel He 177 Greif (Griffin) was a long-range heavy bomber flown by the Luftwaffe during World War II. The introduction of the He 177 to combat operations was significantly delayed, by both problems with the development of its engines and frequent changes to its intended role. Nevertheless, it was the only long-range, heavy bomber to become operational with the Luftwaffe during the war. The He 177 had a payload/range capability similar to that of four-engined heavy bombers used by the Allies in the European theatre.

<span class="mw-page-title-main">Heinkel He 274</span> Prototype bomber aircraft by Heinkel

The Heinkel He 274 was a German heavy bomber design developed during World War II, purpose-designed for high-altitude bombing with pressurized crew accommodation. Due to the Allied advance through Northwest Europe, the prototypes were abandoned at the French factory where they were being built. They were completed after the war by the French and used for high-altitude research.

The Heinkel He 277 was a four-engine, long-range heavy bomber design, originating as a derivative of the He 177, intended for production and use by the German Luftwaffe during World War II. The main difference was in its engines. While the He 177 used four engines in two coupled pairs which proved troublesome, the He 277 was intended to use four unitized BMW 801E 14-cylinder radial engines, in single nacelle installations.

<span class="mw-page-title-main">Bomber B</span> Failed 1939-1943 Luftwaffe medium bomber program

Bomber B was a German military aircraft design competition organised just before the start of World War II intended to develop a second-generation high-speed bomber for the Luftwaffe. The new designs would be a direct successor to the Schnellbomber philosophy of the Dornier Do 17 and Junkers Ju 88, relying on high speed as its primary defence. Bomber B would be a much larger and more capable aircraft, with range and payload far greater than the Schnellbomber, surpassing the largest conventional designs then under consideration. The winning design was intended to form the backbone of the Luftwaffe's bomber force, replacing the wide collection of semi-specialized designs then in service. The Reich Air Ministry was so optimistic that more modest projects were generally cancelled; when the project failed the Luftwaffe was left with hopelessly outdated aircraft.

The Arado E.555 was a long range strategic bomber proposed by the German Arado company during World War II in response to the RLM's Amerikabomber project. The E.555 designation was applied to a series of long range jet bomber designs of various sizes, powerplant, crew and weapon load configurations. As design studies only, no aircraft were developed or constructed and the entire E.555 project was cancelled at the end of 1944.

The Focke-Wulf Ta 400 was a large six-engined heavy bomber design developed in Nazi Germany in 1943 by Focke-Wulf as a serious contender for the Amerikabomber project. One of the first aircraft to be developed from components from multiple countries, it was also one of the most advanced Focke-Wulf designs of World War II, though it never progressed beyond a wind tunnel model.

The Messerschmitt P.1107 was a jet-powered bomber project developed in the final years of the Second World War.

The Dornier Do 417 was a twin-engine multirole combat aircraft. Developed in 1942, it resulted from the Luftwaffe's request for a medium bomber, a contest in which Dornier, Junkers, Heinkel, and Blohm & Voss competed. In the end, the Junkers Ju 188 was chosen by the Luftwaffe, and the Do 417 never entered production.
