The 702nd Strategic Missile Wing was established in July 1958 at Presque Isle Air Force Base, Maine as the only SM-62 Snark missile wing in the USAF. In April, the wing was assigned the 556th Strategic Missile Squadron, which performed intercontinental missile test operations from Patrick Air Force Base, Florida, through June 1959. In July, the 556th moved to Presque Isle, where it was inactivated. Test operations from the Atlantic Missile Range at Cape Canaveral Air Force Station, Florida, were resumed by a wing detachment c. December 1959, continuing until the wing was inactivated. On 27 May 1959, the wing received its first operational missile at Presque Isle. Ten months later, on 18 March 1960, the first Snark missile went on alert status. Thirty are known to have been deployed.
