According to the U.S. “Aerospace Daily” reported on September 18, 2003, on September 10, the U.S. Air Force's B-2A bomber hit a precision strike bomb test conducted at the Utah Test Range to deliver 80 pieces of GBU- 38 JDAM precision-guided bomber attacked a small simulated airport of 1609 meters in length. Each bomb was programmed individually and each attacked a different intended target with an average circular probability deviation of less than 3.05 meters. Many bombs hit directly The goal.
