The USAF BIG SAFARI program office managed the Predator program and was given direction on 21 June 2000 to explore options to arm the aircraft. This led to it being fitted with reinforced wings and stores pylons to carry munitions, as well as a laser designator. The RQ-1 conducted its first firing of a Hellfire anti-tank missile on 16 February 2001; over a bombing range near Indian Springs Air Force Station north of Las Vegas, Nevada, an inert AGM-114C successfully hit a tank target. This led to a series of tests on 21 February 2001 in which the Predator fired three Hellfire missiles, scoring hits on a stationary tank with all three missiles. Following the February tests, the decision was made to move immediately to increment two of the testing phase, which involved more complex tests to hunt for simulated moving targets from greater altitudes with the more advanced AGM-114K version. The scheme was put into service, with the armed Predators given the new designation of MQ-1A. The Predator gives little warning of attack; it is relatively quiet and the Hellfire is supersonic, so it strikes before it is heard by the target.
