HOMERUN was a secret US aerial reconnaissance operation against the USSR in 1956.

Project HOMERUN was conducted between March and May 1956. During that time RB-47E and RB-47H reconnaissance aircraft flew almost daily flights over the North Pole to photograph and gather electronic intelligence over the entire northern section of the Soviet Union.^[1]

Project Homerun used 16 RB-47Es from the 10th SRS and five RB-47Hs from the 343rd SRS. 156 sorties were performed.

On a typical RB-47H reconnaissance mission covering 5,984 mi (9,360 km), the aircraft would fly from Thule, Greenland to the Kara Sea to Murmansk and then return only to find Thule weathered-in, forcing the flight from the air-refueling/decision point near the northeast shore of Greenland to one of three equidistant alternates: Goose Bay, Labrador, London, or Fairbanks, Alaska. Five KC-97s at Thule were required to support this scenario. Two ground spares and one air spare ensured two 20,000 lb (9,090 kg) fuel transfers at a distance of over 600 mi (965 km) from Thule. Tankers returned to Thule to refuel and again repeat the flight to intercept the returning RB-47H six hours later for another air refueling.

When the Soviet government filed an angry complaint with the US government, the US government attributed the overflights to "navigational difficulties".
