All GBU are composed of what?

• A. All GBU are combinations of dumb bombs with guidance packages
• B. GBU are independent from dumb bombs
• C. GBU are inert warheads
• D. GBU require a separate carrier module, not a bomb body

Answer: (A)

GBU are built by combining a conventional unguided bomb body with a guidance package, turning a standard dumb bomb into a precision-guided munition. The bomb body provides the warhead and airframe, while the guidance kit adds sensors, control fins, and electronics to steer the weapon to its target. That combination is what defines a GBU, so the correct idea is that all GBU are combinations of dumb bombs with guidance packages. They aren’t independent from a bomb body, nor inert warheads, and they don’t require a separate carrier module—the guidance kit is attached to the bomb body and delivered as one unit.
