Intended to reach the continental United States, the bombers of the Amerika Bomber project, were designed to carry 3 to 6.5 ton payloads from the Azore Islands to targets like New York City.
The program encompassed multiple airplane proposals and was mainly concerned with developing any kind of aircraft that could make the flight from Germany to the U.S. while also carrying enough explosives to do serious damage.Most of the targets the project had in mind were aluminum and aeronautical companies in the United States. Hitler’s forces hoped that carrying out aerial attacks from a land base against the United States, would force the U.S. to build up a large antiaircraft defense. This would also require the country use more of its antiaircraft capabilities for its own defense rather than for that of Great Britain.
Wasserfall Remote-Controlled A-A Rocket
The Wasserfall was a surface to air missile designed in 1943. It was similar to the V-2 rocket, a surface-to-surface ballistic missile, but unlike the V-2, the Wasserfall was designed to stand ready for periods of up to a month, waiting to be fired on command.In order to operate Wasserfall at night, a special system known as Rheinland was being developed. Rheinland used radar to track the target and a transponder in the missile for locating it in flight. An analog computer guided the missile into the tracking radar beam as soon as possible after launch, using the transponder to locate it. This would enable the operator to see both the target and the missile on a single display, and guide the missile onto the target as easily as it would in delight.
Panzer VIII Maus
Panzerkampfwagen VIII Maus was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Only two hulls and one turret were completed before the testing grounds were captured by the advancing Soviet forces.
These two prototypes (one with, one without turret) underwent trials in late 1944. The complete vehicle was 10.2 metres (33 ft 6 in) long, 3.71 metres (12 ft 2 in) wide and 3.63 metres (11.9 ft) tall. Weighing 200 metric tons, the Maus's main armament was a 128 mm KwK 44 gun (55 calibers long barrel), based on the 12.8 cm Pak 44 anti-tank artillery piece already in use in the casemate-style Jagdtiger tank destroyer, with a coaxial 75 mm gun. The 128 mm gun was powerful enough to destroy all enemy armored fighting vehicles at close or medium ranges, and even some at ranges exceeding 3500 meters.
The principal problem in development of the Maus was finding a powerful enough engine for its weight that could be carried in the tank. Though the design called for a maximum speed of 20 kilometres per hour (12 mph), no engine was found that could power the prototype to more than 13 kilometres per hour (8.1 mph) under ideal conditions. The weight also made it impossible to cross most bridges; it was intended to ford or submerge and use a snorkel to cross rivers.
Flettner Fl 282
Like the Vortex Gun, the Wind Cannon was also developed by a factory in Stuttgart during the war. It was a type of gun that would eject a jet of compressed air against enemy aircraft. It was a strange device consisted of a large angled barrel like a bent arm resting in an immense cradle like some enormous broken pea-shooter lying askew. The cannon worked by the ignition of critical mixtures of hydrogen and oxygen in molecular proportions as near as possible. The powerful explosion triggered off a rapidly-ejected projectile of compressed air and water vapor, which, like a solid "shot" of air, was as effective as a small shell. Experimental trials of the cannon at Hillersleben demonstrated that a 25mm-thick wooden board could be broken at a distance of 200m. Nitrogen peroxide was deployed in some of the experiments so that the brown color would allow the path and destination of the otherwise transparent projectile to be observed and photographed. The tests proved that a powerful region of compressed and high-velocity air could be deployed with sufficient force to inflict some damage. However, the aerodynamics of a flying aircraft would almost surely neutralized the effectiveness of this cannon. In addition the effects of the cannon on a fast-flying aircraft was quite different from that on a fixed ground target. Still, the cannon was installed on a bridge over the Elbe, but with no significant results -- either because there were no aircrafft or simply no successes (as one might suspect). The wind cannon was an interesting experiment but a practical failure.
