Does anyone know of any projects using very simple stealth solutions like a light composite (or even wood, nature's composite) airframe, no engine and almost no metal?
For example, assuming that high explosive itself is not visible to radar, I could see such a solution being attractive for a long-range glide bomb as a cheaper and stealthier alternative to a cruise missile. A sailplane-like glide bomb with a 20:1 glide ratio could glide 75 miles from 20,000 feet. Even without exotic materials and techniquies, if the only metal were a few actuators, sensors, etc. there wouldn't be much for radar to see.
It would also work for one-way special forces delivery, but there there doesn't seem to be much interest in assault gliders these days.
Thoughts?
