We will see how fast it is after landing on gravel and dirt like the C-130 does.
Its still on the drawing board. The one thing going for it is the STOL capability.
A C-130 landed and took off from a carrier in some special tests. Without assist. USS Forestall...
“Altogether, the crew successfully negotiated 29 touch-and-go landings, 21 unarrested full-stop landings, and 21 unassisted takeoffs at gross weights of 85,000 pounds up to 121,000 pounds. At 85,000 pounds, the KC-130F came to a complete stop within 267 feet, about twice the aircraft’s wing span! The Navy was delighted to discover that even with a maximum payload, the plane used only 745 feet for takeoff and 460 feet for landing roll. The short landing roll resulted from close coordination between Flatley and Jerry Daugherty, the carrier’s landing signal officer. Daugherty, later to become a captain and assigned to the Naval Air Systems Command, gave Flatley an engine “chop” while still three or four feet off the deck.”
