The Sherpa is an all-freight version of the Shorts 330 regional airliner with a 5 ft-6 inch square cabin section over an unimpeded hold length of 29 ft. Through-loading is provided via a large forward freight door, and via a full width, hydraullically operated rear ramp door with removable roller conveyors. The C-23 Sherpa is the Army National Guard’s answer to missions requiring an aircraft that is capable of faster, higher-altitude and longer-distance coverage than helicopters. The Sherpa comes with a low operating cost due to its simple, robust construction, compared to that of other cargo aircraft.
There is another one
