The Guided Bomb Unit -15 (GBU-15) modular weapon system is combat proven, precision guided and capable of destroying a variety of heavily defended targets. The GBU-15 can deliver either an MK 84 2,000-pound general-purpose bomb or a BLU-109B 2,000-pound penetrating bomb with pinpoint accuracy via data link control, from low to high altitude, at a significant standoff distance. It is equipped with either a television or an imaging infrared seeker. It was developed by North American Rockwell's Autonetics division and first flown in 1975.
The seeker provides the launch aircraft with visual presentation of the target and surroundings as seen from the weapon. During free flight, this presentation is transmitted by a two-way data link system to the aircraft cockpit television monitor.
The seeker can be either locked onto the target before of after launch for automatic weapon guidance or it can be manually steered by the weapon systems operator.
Carrying forward the modular concept of the GBU-15 guided weapon system, the AGM-130A employs a rocket motor for extended range and an altimeter for altitude control. This powered version of the GBU-15 provides a significantly increased standoff range.
