At least one of the prototypes of the Orlyonok was fitted with a split fuselage freight door.
There have been plans to modify one of the surviving Orlyonoks as a transport, carrying up to 150
passengers in a single deck layout or up to 350 passengers in a twin deck layout,
but regarding their current status this may never happen. A cargo version of the Orlyonok
would be able to carry a 30 ton payload over a 1000 km range with 15t of fuel.
