The U.S. Air Force plans to deliver its newest and deadliest unmanned aircraft, the Reaper, to the theater of operations in Afghanistan. "The Reaper is an attack aircraft loaded to the hilt with weapons," Gen. T. Michael Moseley, a member of the Joint Chiefs of Staff, told ABC News exclusively. Four MQ-9 Reapers, defined by the Air Force as "hunter-killers," are expected to arrive within several months, according to Gen. Moseley. While previous unmanned aerial vehicles (UAVs) have largely served surveillance and reconnaissance functions, the Reaper is geared more toward weapon and attack purposes.

Named for its lethal nature, the Reaper can carry as many as 14 air-to-ground Hellfire missiles, while its precursor, the Predator, only has the capacity for two. If necessary, the new aircraft can substitute 10 Hellfires with two 500-pound bombs. The Reaper can also remain airborne up to 14 hours fully loaded, with a maximum speed of 300 mph versus the Predator’s 135. "It flies higher and carries more than our older systems, giving our skilled and experienced operators additional capability to find, fix, track and engage a target," said Gen. Moseley about the Reaper’s capabilities. "Not only do we give theater military commanders the capacity to surveil the battlespace and keep a vigilant eye on targets and insurgent activities," said Gen. Moseley, "we are also capable of striking those targets." The Pentagon budgeted $349 million for Reaper- and Predator-related spending for the fiscal year 2007, according to the Air Force budget report.
