The B-1, which had its combat debut in Operation Desert Fox in 1998, went to drop thousands of JDAMs during the multi-year wars in Iraq and Afghanistan. The B-1 can hit speeds of MACH 1.25 at 40,000 feet and operates at a ceiling of 60,000 feet. It fires a wide-range of bombs, to include several JDAMS: GBU-31, GBU-38 and GBU-54.
