GBU-31 (JDAM) is a 2000-pound bomb guided by which navigation system?

• A. 2000 pound, GPS guided
• B. 1000 pound, GPS guided
• C. 500 pound, GPS guided
• D. 2000 pound, laser guided

Answer: (A)

The key idea is that this JDAM weapon uses GPS-based navigation to reach its target. The GBU-31 is a 2,000-pound bomb equipped with a GPS-guided guidance kit (with an inertial navigation system as backup). GPS provides precise position information to steer the bomb along the programmed coordinates, enabling accurate strikes in all weather and lighting conditions. The inertial guidance helps maintain guidance if GPS signals are blocked or degraded. Laser guidance, by contrast, requires a laser designator and is used with different bomb families, not JDAM. The 2,000-pound size also matches this particular bomb class.
