This meant the two main rotors angled away from each other, but the arc of the blades crossed. The second gun tube was operational by January 11, 1945 and till February 22, 1945, it fired some 183 rounds, 44 of which hitting the urban targets. Floatplanes had the advantage of being more flexible in water operations, but they were often small and struggled with maneuverability due to the large float on the bottom of the plane. Inspired by the Japanese Fu-Go, American E77 Balloon Bombs were developed in 1950 and tested with biological munitions by US Army’s Chemical Corps. 27. The World War II German air force — the Luftwaffe — was a force to be reckoned with. Compared to Germany and the United Kingdom, the United States ended up behind the curve when it came to building and adopting effective jet aircraft. When a pilot’s prop engine failed in 1945, he was forced to land on the USS Wake Island under jet power. British Prototype aircraft [ Page 1] British Prototypes in 1/72 scale The British aircraft industry produced many unique aircraft, often flown only as prototypes. Luftwaffe commanders also investigated the possibility of using the giant flying boat as a long-range patrol bomber. During most operations (specifically landing and takeoff), the Fireball used its propeller engine, but when they needed extra thrust, the pilots activated the jet engine. However, by the time production was ready in 1944, the Luftwaffe was already fighting on the defensive, and the fleet of Flettner helicopters never materialized. This configuration would give it more versatility in combat, and it would also increase the wing incidence to give it a shorter takeoff run. Some wartime reports show that the bomber was also test flown over the Atlantic Ocean, entering United States airspace before turning back. One of the most futuristic-looking airplanes of the era was the Japanese-designed J7W Shinden, an airplane with a canard design. The first manned test flight was a disaster. However, by that time, the Luftwaffe was on the defensive, and any offensive bomber projects were given low priority. Most of the work in this interceptor aircraft was done by autopilot. When the third prototype disintegrated midair during a level flight, the engineers realized that there was another problem. 1. Of course, it should come as no surprise that making a fighter plane by combining parts from preexisting airplanes does not work. However, during a test flight, the B-20 fell apart and crashed, killing some of the crew. The war ended before the Navy could perform other tests on the airplane. The 39M Csaba was an armoured scout car produced for the Royal Hungarian Army during World War II. They were found guilty and were sentenced between two years to twenty five years in a Siberian labor camp. Junkers, a German company, developed the new bomber from their existing Ju 290 heavy transport. Then the pilot and the fuselage containing the motor of the rockets would land using two different parachutes. There is a common saying that necessity is the mother of all invention. Quite simply, the BI-1 was too fast for its own good. Most of these planes, like the P-51 and P-47, were still under development and hadn’t reached their peak performance. But ice proved unsuitable as natural icebergs have very small surface above water for aircrafts to land, are prone to roll over and splits easily. Due to functional failures, tractor gear problems, public ridicule and impracticality, the Bob Semple Tanks were rejected to be included into New Zealand Army and was restored back to tractors. Image used: Illustrated image of a WWII Bergship under Project Habakkuk. Half of the B-20’s fuselage was a retractable float. albeit accidentally. When the war began, the United Kingdom did not have adequate information about the Luftwaffe, including what types of airplanes it flew. Entries are listed below in alphanumeric order (1-to-Z). Image used: A captured Ba 349 on display at Freeman Field in Indiana, United States in September 1945. Even though the He 100 never reached frontline service, it played a fascinating role in early propaganda efforts. The project ended in the late 1940s. A 130m (430 ft) long V-3 Cannon with 165km range was almost fully constructed at bunkers at Pas-de-Calais region in Northern France. But it wasn’t just size that made these ships so formidable. After all, he set the record for “biggest Axis airplane ever destroyed by an Allied pilot.”. However, two more V-3 Cannons with shorter barrels of 50m (160ft) were constructed at Trier city in Germany in late 1944. During the ’30s and ’40s, famous aircraft designer Jack Northrop worked tirelessly on his idea for flying wing airplanes. The intermeshing rotors gave the helicopter the advantage of not needing a tail rotor to offset the torque from the main rotors. Taking advantage of the situation, Joseph Goebbels announced that the Luftwaffe was fielding a new He 113 fighter, but in reality, it was just a repainted He 100 prototype. Rocket motor tests commenced in 1942, but powered flights quickly revealed that the BI-1 only had 15 minutes of flight time from the moment the pilot ignited the rocket on the ground. The shells inside the cannon had the ability to achieve a muzzle velocity of 1,500m/s (4,900 ft/s) and fire 300 shells per hour. A subreddit spawned from /r/weirdwheels with the same intent, only with planes! These were used against Luxemburg which was 43km (27mi) away from the V-3 cannons and had been liberated in September 1944. These were comparatively cheaper weapons which were designed to use the Tropospheric jet stream over the Pacific Ocean and hit targets in United States. This sub is for documenting all those strange planes out there from prototype to production. Allison and the Fisher Body Division of the General Motors Corporation worked together to make a new airplane around the engine. With the war turning in the Allies’ favor, Blohm & Voss discontinued work on the airplane. There were no blueprints of interior of this tank; assumptions were made based on similar German battleships.

It melted slower than ice, had the strength and toughness as good as that of concrete. During the last months of WWII, Japan had a schedule on September 22, 1945, to use plague bombs against San Diego, California. It did not have conventional armor plating rather corrugated manganese plating hardly good enough to deflect bullets. Check out his blog at zacherybrasier.com. With that limitation, testing ground to a halt, and the war turned in favor of the Soviets, ensuring that there was no further development of defensive rocket planes. All aircraft are allowed, including helicopters (despite the sub name). Though there were high hopes of their Japanese designers, only 300 of these were observed or found reaching the United States causing only a small amount of damage to US facilities and 6 deaths. However, when the German invasion began, Stalin told engineers Alexander Bereznyak and Aleksei Isayev to get the airplane ready as soon as possible. Even during testing, the J7W barely got any flight time, only clocking a combined 45 minutes in the air over three test flights. This proves that the Bat Bombs worked. It could carry 8 combatants, had an armor of just 20mm and a speed of 24 kmph. It was 60 feet (18 m) by 30 feet (9m), weighing 1,000 tons and a one-horsepower motor was used to keep it frozen. The Japanese Unit 731 was a covert Chemical and Biological warfare research & development unit that operated between 1935 and 1945 participating in the Second Sino Japanese War (1937-1945) and WWII. But Hirohito was forced to surrender five weeks earlier. So the Blackburn Aircraft Company decided to design an airplane that joined the best elements of floatplanes and flying boats, ending up with the oddball B-20 (somewhat similar to the one depicted above). It was their first jet airplane. Pyke then proposed a frozen composite called Pykrete, made of 14% sawdust or wood pulp and 86% water. British unorthodox inventor Geoffrey Pyke is known for coining an idea of a material called pykrete and proposing to construct the ship Habakkuk from it during the WWII.
