When Lt. James H. Flatley III was told about his new assignment, he thought somebody was pulling his leg. “Operate a C-130 off an aircraft carrier? Somebody’s got to be kidding,” he said. But they weren’t kidding. In fact, the Chief of Naval Operations himself had ordered a feasibility study on operating the big propjet aboard the Norfolk-based USS Forrestal (CVA-59). The Navy was trying to find out whether they could use the Hercules as a “Super COD” – a “Carrier Onboard Delivery” aircraft. The airplane then used for such tasks was the Grumman C-1 Trader, a twin piston-engine bird with a limited payload capacity and 300-mile range. If an aircraft carrier is operating in mid-ocean, it has no “onboard delivery” system to fall back on and must come nearer land before taking aboard even urgently needed items. The Hercules was stable and reliable, with a long cruising range and capable of carrying large payloads.
The aircraft, a KC-130F refueler transport (BuNo 149798), on loan from the U.S. Marines, was delivered on Oct. 8. Lockheed’s only modifications to the original plane included installing a smaller nose-landing gear orifice, an improved anti-skid braking system, and removal of the underwing refueling pods. “The big worry was whether we could meet the maximum sink rate of nine feet per second,” Flatley said. As it turned out, the Navy was amazed to find they were able to better this mark by a substantial margin.
In addition to Flatley, the crew consisted of Lt.Cmdr. W.W. Stovall, copilot; ADR-1 E.F. Brennan, flight engineer; and Lockheed engineering flight test pilot Ted H. Limmer, Jr. The initial sea-born landings on Oct. 30, 1963 were made into a 40-knot wind. 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.
Lockheed’s Ted Limmer, who checked out fighter pilot Flatley in the C-130, stayed on for some of the initial touch-and-go and full-stop landings. “The last landing I participated in, we touched down about 150 feet from the end, stopped in 270 feet more and launched from that position, using what was left of the deck. We still had a couple hundred feet left when we lifted off. Admiral Brown was flabbergasted.”
The plane’s wingspan cleared the Forrestal’s flight deck “island” control tower by just under 15 feet as the plane roared down the deck on a specially painted line. Lockheed’s chief engineer, Art E. Flock was aboard to observe the testing. “The sea was pretty big that day. I was up on the captain’s bridge. I watched a man on the ship’s bow as that bow must have gone up and down 30 feet.” The speed of the ship was increased 10 knots to reduce yaw motion and to reduce wind direction. Thus, when the plane landed, it had a 40 to 50 knot wind on the nose. “That airplane stopped right opposite the captain’s bridge,” recalled Flock. “There was cheering and laughing. There on the side of the fuselage, a big sign had been painted on that said, “LOOK MA, NO HOOK.”
From the accumulated test data, the Navy concluded that with the C-130 Hercules, it would be possible to lift 25,000 pounds of cargo 2,500 miles and land it on a carrier. Even so, the idea was considered a bit too risky for the C-130 and the Navy elected to use a smaller COD aircraft. For his effort, the Navy awarded Flatley the Distinguished Flying Cross.
