To replace the B-47s, the Wing was assigned the Boeing B-52G Stratofortress bomber and received its first aircraft christened "Champlain Lady" on 19 June 1966. After the arrival of the new type, another new unit was assigned to the Wing on 25 January 1967, the 310th Air Refueling Squadron. On 21 January 1968, tragedy struck the wing again when B-52G 58-188, crashed near Thule Air Base in Greenland while on a Chrome Dome mission. The aircraft was flown by a crew from the 528th Squadron and was carrying four hydrogen bombs when it crashed into an ice covered bay at the western tip of Greenland. The crew of seven was composed of Capt. John Baug (commander), Capt. Leonard Svitenko (co-pilot), Maj. Frank Hopkins (radar navigator), Capt. Curtis Criss (navigator), Capt. Richard Marx (electronic warfare), SSgt. Calvin Snapp (gunner) and Maj. Alfred J. D'amario (safety officer from Wing HQ). Sadly, Capt. Svitenko was killed during the crash.
