While he was in the U.S., the Communist revolution made it exceptionally dangerous to return home. In early 1918 Seversky was appointed by the Czarist Government to study aircraft design and manufacturing in the United States. Ultimately, Seversky was credited with no less than shooting down thirteen German aircraft before the Czarist government reached an armistice with the Kaiser Wilhelm in 1917. Unfazed, he managed to convince his commanders to allow him to fly again using an artificial leg. Seversky flew with the Czarist Naval Air Service and suffered the loss of a leg as a result of being shot down in 1915. Seversky, a Russian national, was a veteran of World War One. de Seversky and his highly innovative aircraft of the early 1930s. The development of the Thunderbolt was a classic instance of design evolution tracing its origin back to Alexander P. made Fighter, the story of how it came to exist is at least as interesting as its many accomplishments. Produced in greater numbers than any other U.S. Despite its size, the P-47 proved to be one of the best performing fighters to see combat. Parked alongside any of its wartime contemporaries, the Thunderbolt dwarfs them with its remarkable bulk. The Republic P-47 Thunderbolt had the distinction of being the heaviest single-engine fighter to see service in World War Two. US called 'Liz'.Aviation Darwinism -В The Republic P-47 Thunderbolt Six prewar prototypes were build and four used as long-range Navy freighters under the designation Nakajima G5N2 Shinzan-Kai. Once theД®xperienced pilots were gone, there were few well trained replacements.ДЇour engine bomber developed from Douglas DC4E was unsuccessful for intended 3000 nmile torpedo bomber. Japanese pilots were willing to die and, early in the war, didn't even wear parachutes. The J2M 'Jack' (370 mph), also land based, entered service in 1944, but only 475 aircraft could be built.ДЄmerican aircraft carried self-sealing gas tanks, whereas Japanese planes readily flamed.

Japan manufacture depended on many small machine shops and could not get new designs into production once they were geared to produce Zeros, thus they could not efficiently improve that plane or introduce improved designs.Д¬hanges throughout the war slowly did occur : increase engine from 925 hp to 1,130, shorten wing, improved 20mm guns, change. The US introduced massive training programs and had high tech industrial capacity. There were limited replacement for either. Japan started with war experienced pilots and a buildup of excellent aircraft. Japanese aircraft were designed from experiences of the war in China for attack against a weak foe. U-boat menace, and kept Japan's submarines suppressed, for example, 6 subs were sunk in 12 days by ONE US destroyer escort, England (DE-635). USN payed much attention to anti-submarine defense, initiated from the Atlantic Japan started the war using their submarines successfully for anti-shipping and anti-fleet activities, but soon feltД¬ompelled to disarm much of their submarine fleet for use in supply of remote island. Meanwhile, USN submarines sank the carriers and merchant fleets that were the life of Japan. Japan never considered anti-submarine activities for carriers. The US launched 12 CV, 9 CVL, and 50 CVE. In this period Japan launched 1 CV, 5 CVL, and 2 CVE. Shipbuilding resources were spent on the supercarrier Shinano and on conversion of ocean liners to escort carriers. Have built Shokaku class carriers, the equivalent of the Essex class, yet only one was build, Taiho. The Japanese always suffered from gasolineДЇires when hit, whereas the American carriers learned to first empty gas lines, then to flush them with CO 2 to prevent secondary explosions.Дuring the lull in the naval air war, late'42 to mid'44, Japan should Some carriers converted from other designs were slow and had to use more flight deck for takeoff thereby interfering Continually upgraded, but the design was dated by 1944.Д¬arriers did not have catapults, therefore flight operations depended on speed into Japanese Naval AirCraft of WW II Japanese Naval Aircraft of WW2ДЇixed landing gear, open cockpit 1,100 builtД«est performing fighter of any country in early WW2, but vulnerable.
