How large a transport could routinely use a Ford-class carrier

What is the largest aircraft that could be designed for routine Ford-class carrier operation?

Probably a STOL transport around C-295 or Short Sherpa size, with wingspan and deck handling limiting further growth.

The best starting point is an aircraft already designed for short takeoff and landing, because its operating stresses are closer to carrier requirements. The C-295 approaches the useful size limit but brings a wide wingspan that complicates deck handling and stowage. The smaller Short Sherpa offers a more manageable adaptation and already reflects austere-field design priorities. Routine operation from a Ford-class carrier therefore depends as much on wing geometry and low-speed handling as on raw payload.
