The Reaper is larger than the well-known Predator, with a 66-foot wingspan and the ability to carry a payload of electronics and weapons of 3,800 pounds. It can cruise at 230 mph with a range of about 1,150 miles and a ceiling of 50,000 feet. Semmel said the cost of a Reaper is $4 million to $5 million. The federal government has pegged the cost of a four-plane Reaper package at about $57 million, including the necessary ground station and satellite uplink.
