South Africa's Kentron is developing Seraph, a stealthy recon drone that would be 18 feet long, have a 9-foot wingspan, and fly at Mach-0.86. The aircraft would be designed for the low-cost market (for countries that cannot afford superior but more expensive US-built drones). The company (now part of British Aerospace) says it is now trying to develop inexpensive stealth materials that could bring Seraph to market.--Stephen V Cole
