How the AH-64 Apache Became the Ultimate Attack HelicopterEarly in the morning of January 17, 1991, eight sleek helicopters bristling with missiles swooped low over the sands of the An Nafud desert in as they soared towards the border separating Saudi Arabia from Iraq.At 2:30 a.m., the choppers fanned out and set to work in teams of two. Rocket motors flashed as Hellfire missiles streaked towards two Iraqi radars powerful enough to potentially pick up the faint signature of a stealth plane.Minutes after the radars had been reduced to rubble, Nighthawk stealth jets soared through the twenty-mile-wide radar gap, headed for Baghdad.
