Several more unpowered flights took place that month. Spurred by the success of the Heinkel He 178, the world's first true jet which flew in August 1939, the German leadership pressed for … Although the Me 163 had very short endurance, it had originally been even shorter. In the original design, the engine had only one throttle setting, "full on", and burned through its fuel in a few minutes. It was a powered variant of the Me 321 military glider and was the largest land-based transport aircraft of the war. Trois prototypes furent construits, mais aucun ne vola réellement par ses propres moyens. El Messerschmitt Me 263 fue un interceptor propulsado con cohetes desarrollado a partir del Me 163 Komet hacia el final de la Segunda Guerra Mundial.Se construyeron tres prototipos, pero no voló ninguno por sus propios medios ya que la situación militar se deterioraba rápidamente en Alemania, lo que impidió que se completara el programa de pruebas. As the Me 263 was not a part of the In April, the Americans occupied the plant and captured the three prototypes and the mock-up. Samolot Messerschmitt Me 263 (Junkers Ju 248) bazował na prototypie Messerschmitt Me 163 D V1, od którego różnił się tylko kroplowatym kształtem osłony kabiny pilota. Not only did this further limit endurance, in flight testing, pilots found the aircraft quickly exhibited compressibility effects as soon as they levelled off from the climb and speeds picked up. Messerschmitt Me 263 był dłuższy od Messerschmitta Me 163 B o 0,85 m. Not only did this further limit endurance, in flight testing, pilots found the aircraft quickly exhibited Throughout development the RLM proved unhappy with the progress on the 163 project, and eventually decided to transfer development to At Junkers, the basic plan of the 163C was followed to produce an even larger design, the Ju 248. A total of 213 are recorded as having been made, 15 being converted from the Me 321. The biggest problem had to do with the Test flights were later stopped because of fuel shortages for the Bf 110 towplanes. Though best remembered as a late-war weapon, the design of the Messerschmitt Me 262 began prior to World War II in April 1939. The V2 was destroyed but another prototype ended up in the US. Le moteur ne fut jamais installé en raison de la détérioration de la situation militaire de l'Allemagne à la fin de la guerre qui handicapa grandement le programme de tests. The Me 323 was the result of a 1940 German requirement for a large assault glider in preparation for Early in 1941, as a result of feedback from Transport Command pilots in Russia, the decision was taken to produce a motorized variant of the Me 321, to be designated Me 323. For defensive armament, it was armed with five 13 mm (.51 in) By September 1942, Me 323s were being delivered for use in the On 22 April 1943, a formation of 27 fully loaded Me 323s was being escorted across the A ruined but complete wreck was found in 2012, in the sea near Dôvod ukončenia projektu bola rapídne sa zhoršujúca vojnová situácia nacistického Nemecka a priorita pokračovania vývoja úspešnejších typov.

Three prototypes were built but never flown under their own power as the rapidly deteriorating military situation in Germany prevented the completion of the test program. It was decided to use French Initial tests were conducted using four Gnome engines attached to a strengthened Me 321 wing, which gave a modest speed of 210 km/h (130 mph) – 80 km/h (50 mph) slower than the The four-engined Me 323C was considered merely a stepping stone to the six-engined D series; it still required the five-engined The selection of the six engines, and their specific placement on the wing's leading edge, were fitted The "D" series had a crew of five: two pilots, two Maximum payload was around 12 tonnes, although at that weight the Hellmuth Walter Werke-designed Some Me 321s were converted to Me 323s, but the majority were built as six-engine aircraft from the beginning; early models were fitted with wooden two-blade The Me 323 had a maximum speed of only 219 km/h (136 mph) at sea level and speed dropped with altitude.
