Which GBU adds an optional precision laser guidance set in addition to its GPS/INS guidance system?

The GBU-54 is designed to incorporate an optional precision laser guidance set alongside its GPS/INS (Global Positioning System/Inertial Navigation System) guidance. This dual guidance capability enhances its effectiveness in diverse combat scenarios, allowing it to engage targets with high precision in different environments, including those where GPS signals may be degraded or unavailable. The laser guidance allows for adjustments in targeting based on real-time inputs, providing a flexible solution for accuracy against time-sensitive or moving targets.

This combination makes the GBU-54 particularly versatile, as it can operate effectively under various conditions by leveraging both satellite navigation and laser guidance, thereby increasing the likelihood of mission success and minimizing collateral damage.
