Which of the following GBU types includes a laser for targeting?

The GBU-54 is known for incorporating a laser guidance system, which enhances its targeting capability. This weapon combines GPS guidance with laser guidance, allowing it to engage moving targets effectively as well as stationary ones. The integration of both systems means it can take advantage of GPS for wide-area targeting and then rely on laser designation for precision strikes. This dual functionality makes the GBU-54 particularly versatile in modern combat scenarios where accuracy can be critical.

In contrast, the other options are primarily guided by different means. The GBU-32 and GBU-38 rely on GPS for guidance without the additional use of laser targeting. The GBU-20, while also a precision weapon, does not have the same dual-mode guidance characteristics as the GBU-54, focusing instead on traditional guided munitions strategies. Thus, the GBU-54’s unique laser targeting feature distinguishes it from the other choices.
