A large transport's maximum takeoff weight includes fuel as well as cargo. Increasing the cargo carried by the C-5 Galaxy reduces the fuel and range available within that limit. Maximum payload therefore needs to be considered alongside the distance an aircraft must fly. Transport lifting capacity also does not establish the routine bomb load or operating capability of a bomber.

The C-5 comparison: payload, fuel, and range
Large transport payloads carry fuel and range penalties and do not establish what a bomber can routinely deliver.
