The weapon is a guidance kit based on the existing Enhanced Paveway II Enhanced Computer Control Group (ECCG) added to a modified Mk 82 general-purpose bomb with increased penetration performance. The new ECCG contains a Height of Burst (HOB) sensor enabling air burst fusing options, and a SAASM (Selective Availability Anti Spoofing Module) compliant GPS receiver. It can be launched either IMU (Inertial Measurement Unit) only, given sufficiently good Transfer Alignment, or using GPS guidance. Terminal laser guidance is available in either navigation mode.
The Paveway IV entered service with the British Royal Air Force in 2008.  It has yet to be accepted into service with the United States military whom have been pursuing the development the Laser-JDAM and a dual mode small-diameter bomb.
