The Texas Instruments BOLT-117 (BOmb, Laser Terminal-117), retrospectively redesignated as the GBU-1/B (Guided Bomb Unit) [1] [3] was the world's first laser-guided bomb (LGB). It consisted of a standard M117 750-pound (340 kg) bomb case with a KMU-342 laser guidance and control kit.
The M117 can be configured with a conical low-drag tail for medium and high altitude deliveries or a high-drag tail fin for low-altitude drops, delaying the bombs hitting their targets ensuring bombers are out of the blast zone before detonation. [6] The M117 was the basis for the BOLT-117, the world's first laser-guided bomb. [7]
In 1962, the US Army began research into laser guidance systems and by 1967 the USAF had conducted a competitive evaluation leading to full development of the world's first laser-guided bomb, the BOLT-117, in 1968. All such bombs work in much the same way, relying on the target being illuminated, or "painted," by a laser target designator on ...
A laser-guided bomb (LGB) is a guided bomb that uses semi-active laser guidance to strike a designated target with greater accuracy than an unguided bomb. First developed by the United States during the Vietnam War , laser-guided bombs quickly proved their value in precision strikes of difficult point targets.
The 21,600-pound (9,797-kg) GBU-43 (Guided Bomb Unit), one of only 15 ever built, was developed after the U.S. military found itself without the ordnance needed to deal with al Qaeda tunnel ...

The VKS also fields several purpose-designed glide bombs, including the massive 3,306-lb satellite-guided KAB-1500S-E glide bomb with an effective range of 31 miles, and the smaller UPAB-500B ...
The bomb is the FAB-1500, essentially a 1.5-tonne weapon of which nearly half comprises high explosives. It is delivered from above by fighter jets from a distance of some 60-70 kilometers, out of ...
