In the late thirties and early forties, the Soviet aviation industry had developed and tested a variety of aircraft design concepts, some quite peculiar. While generally unknown around the world, a number of these strange aircraft would represent a serious departure from anything resembling their contemporaries. Such is the case with Victor Nikolayevich Belyayev’s DB-LK experimental long-range bomber.
The Linke-Hofmann R.I was an experimental heavy bomber developed by the German Empire in 1917. The R.I would be unique, as one of the first prototypes to be constructed mostly out of a translucent material known as cellon, with the idea that it aircraft would be harder to spot. Unfortunately for the designers, cellon is highly reflective and ended up making the craft a much more noticeable target. After the failure with cellon, more work continued on the prototypes, now of normal fabric skinned construction. Due to poor performance caused by several design choices, the type was not mass produced and was subsequently cancelled.
Throughout 1945, it was becoming clear to Japanese Army Officials that an Allied invasion of the Japanese mainland was growing ever more likely. Seeing as their navy and airforce had been mostly destroyed, they needed new weapons to fight off a probable Allied attack on Japan. Among these new weapons were Kamikaze aircraft, with many older designs having already been used in this role. However, some Kamikaze aircraft were to be specially designed for such a role, being cheap and able to be built quickly and in great numbers. One such aircraft was the Ki-115 Tsurugi (Sabre) which was built in small numbers, and never used operationally.
Following the failure of the Yak-2, Yakovlev attempted to salvage the project. One of the attempts that saw limited production was the Yak-4. While it would be powered by a somewhat stronger engine, it too would prove to be a failure and only some 100 aircraft would be built by 1941.
The Avia S-199 was a post Second World War fighter produced in Czechoslovakia. A total of 532 airplanes of different versions were built and used by the Czechoslovenské letectvo (Czechoslovak Air Force) from 1947 to 1955, and 25 planes were used by the Israeli Air Force (IAF) of the newly formed State of Israel between 1948 and 1949.
Following a request from the German Ministry of Aviation (Reichsluftfahrtministerium – RLM), in 1940, German aircraft manufacturer Arado began working on a new multi-purpose jet powered plane. Arado’s work would lead to the development of the advanced and sophisticated Ar 234 aircraft. During 1943, a small series of eight prototypes would be built and used mainly for testing, but some saw operational service.
The Northrop P-61 was a night fighter designed to fulfill a largely overlooked gap in America’s air defenses in the years prior to its entry into the Second World War. Ambitious and groundbreaking, the P-61 would be the first fighter aircraft designed to carry a radar and was to be equipped with a state of the art remotely operated turret. However, the aircraft suffered numerous technical problems which led to many delays in its development, and several faults made their way into operational aircraft. Despite its quirks, the plane proved to be popular with its pilots, effective in service, and far more capable in its mission than preceding American night fighters, while also proving itself effective in roles not envisioned at the time of its design.
The Sombold So 344 was a highly specialized interceptor designed by Heinz G. Sombold to attack Allied bomber formations over Germany in 1944. The way the aircraft would attack, however, would be extremely unconventional. Being deployed from a bomber mothership, the So 344 would fly towards an approaching bomber formation and launch its entire nose cone, which was a 400 kg (882 Ib) rocket, at the enemy bombers in an attempt to destroy as many as possible. From there, the So 344 could either attack the remaining bombers or return to base and land on a skid. Work went as far as wind tunnel models for the aircraft but none would be built.
During the war, German scientists and engineers managed to develop and build a number of jet powered aircraft, several of which went on to see combat. What is generally less known are the large number of experimental jets that were proposed and prototyped. These designs utilized a great variety of engines, airframes, and weapons. One of these unfinished projects was the Messerschmitt P.1101 jet fighter.
The Macchi M.C. 200 ‘Saetta’ (Lightning) was a fighter aircraft developed by Aeronautica Macchi (AerMacchi) of Italy around the mid-1930s, resulting in one of the most produced and used aircraft of the Regia Aeronautica (Italian Royal Air Force) during the Second World War. It yielded good results on all fronts where the Italian forces operated, from the hot and dusty desert of North Africa, to the cold and snowy Russian steppes.
