The GBU-54 is best described as which combination?

• A. 500 pound, GPS guided, laser updated
• B. 1000 pound, GPS guided
• C. 500 pound, laser guided
• D. 500 pound, GPS guided

Answer: (A)

The GBU-54 is a 500-pound precision-guided bomb that blends GPS guidance with laser terminal updates. It uses GPS/INS to bring it close to the target area, then a semi-active laser seeker in the tail aligns the bomb with the laser designated spot to refine the hit in the final phase. That combination means the guidance is not just a pure GPS path or a pure laser lock; the laser data updates the terminal guidance while the GPS keeps the overall trajectory on target. The 500-pound class matches the GBU-54’s size, and the presence of laser updating differentiates it from a purely GPS-guided bomb or a purely laser-guided one. The other options assign the wrong weight or omit the laser updating aspect, so they don’t describe this weapon as accurately.
