Which guided-bomb unit (GBU) is known for using a 2,000 pound bomb body?

The guided-bomb unit (GBU) that utilizes a 2,000 pound bomb body is the GBU-10. This model is designed to accommodate a larger payload, which enhances its effectiveness against fortified or high-value targets by providing a greater explosive impact. The GBU-10 is primarily based on the Mark 84 bomb, one of the largest conventional bombs used in air-to-ground applications.

In contrast, the other guided-bomb units listed have different bomb body weights: the GBU-12 typically uses a 500-pound bomb body, while the GBU-24 is aligned with the 2,000-pound class but primarily features the Mark 84 or the BLU-109 depending on the configuration and target engagement criteria. The GBU-49 works with a 500-pound class bomb as well. This distinction in the bomb body weights helps categorize these systems based on their intended roles and target engagements in warfare.
