As the name suggests, this is my idea for a very-high-altitude (70,000 ft +), stealthy UCAV. It's primary duties include recon and target designation:  for example, it might track a moving convoy from overhead while illuminating it with a targeting laser:  a standoff missile already in flight could then hit the convoy precisely and accurately. Endurance is on the order of one week.



The design consists of a high-aspect-ratio wing set at an asymmetrical diagonal and punctuated by several jet engine / sensor / fuel pods.
