Наиболее успешным признано применение с B-1B управляемых авиабомб (УАБ) семейства JDAM: GBU-31 и GBU-32. Особо эффективным признан тактический прием, когда 24 УАБ калибра 2000 фунтов (900 кг) за один заход точно "укладываются" по 24 целям в оборонительной полосе противника, создавая в ней брешь. Для описания такой тактики генерал-майор Дэниел Лист, шеф офиса эксплуатационных требований к воздушным и космическим системам в Пентагоне, придумал новый термин: "массированная точность".

Up to 30 GPS satellites fly, mostly in highly inclined (polar) orbits, at altitudes around 20,000 km. This means that there will be between four and eight of them resonably high in the sky above any site on the Earth at any time.

...Guidance is accomplished via the tight coupling of an accurate Global Positioning System (GPS) with a 3-axis Inertial Navigation System (INS). The Guidance Control Unit (GCU) provides accurate guidance in both GPS-aided INS modes of operation (13 meter (m) Circular Error Probable (CEP)) and INS-only modes of operation (30 m CEP). INS only is defined as GPS quality hand-off from the aircraft with GPS unavailable to the weapon (e.g. GPS jammed). In the event JDAM is unable to receive GPS signals after launch for any reason, jamming or otherwise, the INS will provide rate and acceleration measurements which the weapon software will develop into a navigation solution. The Guidance Control Unit provides accurate guidance in both GPS-aided INS modes of operation and INS-only modes of operation. This inherent JDAM capability will counter the threat from near-term technological advances in GPS jamming.
