Project COLDFEET was a 1962 Central Intelligence Agency (CIA) operation to extract intelligence from an abandoned Soviet Arctic drifting ice station. Due to the nature of its abandonment as the result of unstable ice, the retrieval of the operatives used the Fulton surface-to-air recovery system.
What became known as Operation Coldfeet began in May 1961, when a naval aircraft flying an aeromagnetic survey over the Arctic Ocean reported sighting an abandoned Soviet drift station. A few days later, the Soviets announced that they had been forced to leave Station NP 9 (a different station, NP 8 ended up being the target) when the ice runway used to supply it had been destroyed by a pressure ridge, and it was assumed that it would be crushed in the Arctic Ocean.
The prospect of examining an abandoned Soviet ice station attracted the interest of the U.S. Navy's Office of Naval Research. The previous year, ONR had set an acoustical surveillance network on a U.S. drift station used to monitor Soviet submarines. ONR assumed that the Soviets would have a similar system to keep track of American submarines as they transited the polar ice pack, but there was no direct evidence to support this. Also, ONR wanted to compare Soviet efforts on drift stations with U.S. operations. The problem was how to get to NP 9. It was far too deep into the ice pack to be reached by an icebreaker, and it was out of helicopter range.
To Captain John Cadwalader, who would command Operation Coldfeet, it looked like "a wonderful opportunity" to make use of the Fulton surface-to-air recovery system. Following a recommendation by Dr. Max Britton, head of the Arctic program in the Geography Branch of ONR, Rear Admiral L. D. Coates, Chief of Naval Research, authorized preliminary planning for the mission while he sought final approval from the Chief of Naval Operations. The mission was scheduled for September 1961, a time of good weather and ample daylight. NP 9 would be within 600 miles (970 km) of the U.S. Air Force base at Thule, Greenland, the planned launching point for the operation.
