The Horten Ho 229, one of many Luftwaffe's mythical mystery tasks or so-called 'wonder weapons', was once essentially the most enigmatic airplane designs to emerge from international battle II. In many ways a precursor to the 'stealth' thought, it was once in actual fact prior to its time compared to its contemporaries. The Ho 229 was once deliberate because the first of the following new release of German jet opponents to stick to on from the Messerschmitt Me262, for you to create a high-speed cannon-equipped fighter-bomber and reconnaissance airplane.

The design called for a six foot long vehicle with an 85 gram fully-loaded weight. Its top speed design goal was about 30 knots, with an endurance of about 20 minutes and an altitude ceiling of 300 feet. The craft would use an electric engine, which would make the vehicle extremely difficult to detect beyond an altitude of 100-200 feet. The individual cost of each UAV was projected to be in the $3,000-5,000 range. One worry during the design phase was the effect of operating in high winds, with restriction of such vehicles being unable to operate with wind speeds above 30 knots.
Some technical problems, though, could challenge the development of such a system. It was explained that being able to communicate the wide-band communications you need for video imagery at 50 kilometers is difficult and would have to be addressed for success with this concept. Several other launching devices were also considered, including the Crusader self-propelled howitzer, along with the possibility of mortar or rocket launch systems. S. Army was the prime investigator in this effort, with the Missile Research and Development Center at Redstone Arsenal, Alabama, and the Army Research Laboratory at Aberdeen Proving Ground, Maryland.
The "wings" touch the fuselage at both the front and rear of the fuselage. There are also a pair of canted rear fuselage fins, something akin to those used on the F/A-18 fighter. As of press time, there was no firm hardware contract, just a study examining the possible mission capabilities of such a system. Along with other air vehicles, this system could J INHABITED COMBAT AIR VEHICLE (UCAY) This interesting contractor UAV design shows a delta wing configuration with bird-like wings. S.
