Which Boeing aircraft has the largest cargo capacity?

The Boeing 747-8 Freighter holds the title for the largest cargo capacity among Boeing aircraft. Its advanced design accommodates a maximum payload capacity of approximately 140 metric tonnes (approximately 307,000 pounds) and features an impressive volume of cargo space due to its unique nose that can be raised for loading oversized cargo. This capability, combined with a significant dimension of the main deck, allows the aircraft to transport large, heavy items efficiently.

In comparison, while the 747-400 Freighter is a competent cargo aircraft, its capacity falls short of that of the 747-8 Freighter. The Boeing 777 Freighter, while notable for its efficiency and range, is designed for a lower maximum payload. Similarly, the Boeing 767 Freighter, although capable, does not match the capacity or versatility of the 747-8 Freighter, which is specifically optimized for heavy and voluminous loads. The design and advancements in technology of the 747-8 contribute to its status as the leading large cargo aircraft in the Boeing fleet.
