Operation Sandy was the codename for the post-World War II launch of a captured V-2 rocket from the deck of the United States Navy aircraft carrier USS Midway on September 6, 1947. It marked the first launch of a large rocket, and the only time for a V-2, from a ship at sea. Operation Pushover was a follow-up test in late 1949 to assess the danger to a carrier from a V-2 explosion.
