The US Department of Defense is considering using the Teledyne Ryan Aeronautical Global Hawk long-endurance unmanned air vehicle to shoot down theatre ballistic missiles in their boost phases.
The Global Hawk, being prepared for its first flight, is among several options under study. A modified Global Hawk mounting an infra-red search-and-track sensor and missiles in place of its reconnaissance sensors is one proposal. Fuel and endurance would be traded to carry the weaponry, but significant on-station endurance is still achievable, says the Pentagon.
It says, however, that technical challenges need resolving, including continued target tracking and interceptor guidance during engagement. The cost of a fleet is projected at $1-2 billion for 24-74 vehicles, plus ground stations.
