The 134th was equipped with F-47D Thunderbolts and was assigned to the Maine ANG 101st Fighter Group. On 1 December 1948, under the command of First Air Force and Air Defense Command of the U.S. Army Air Force, the entire 101st was transferred to the Continental Air Command (CONAC) shortly after the U.S. Air Force was established on 18 September 1947 as a separate branch of the Armed Forces. Air Defense Command The mission of the 133rd Fighter Squadron was the air defense of New Hampshire. With the surprise invasion of South Korea on 25 June 1950, and the regular military's complete lack of readiness, most of the Air National Guard was federalized placed on active duty. The 133rd was federalized on 10 February 1951 and assigned to the federalized Maine ANG 101st Fighter-Interceptor Wing, although it initially remained stationed at Grenier AFB, mostly flying gunnery practice missions. Its mission was expanded to include the air defense of New England, although a majority of officers and a substantial number of airmen saw duty overseas in different theaters of operations including Korean combat missions. The squadron was then attached to the Air Defense Command 23rd Fighter-Interceptor Wing at Presque Isle AFB, Maine, on 1 April 1951 with no change of mission. It was reassigned to the 4711th Defense Wing on 6 February 1952 at Presque Isle AFB. It was released from active duty and returned to the control of the State of New Hampshire on 1 November 1952. With the end of the Korean War, the squadron's aircraft were first upgraded to F-51H Mustangs then to the F-94 Starfire on 16 June 1954. With the 101st FIG consisting of Maine, New Hampshire, and Vermont Air Guard units, the group began holding summer camp at Otis Air Force Base after they began flying F-94s. New Hampshire's planes flew much more than those of Maine and Vermont. They logged 675 hours and a total of 752 pilot hours, which is approximately 250 more than the other two states. The mission of the 133rd was to provide front line defense for the United States and to intercept aircraft not readily identifiable by radar or pre-filed flight plan. The radar detection station at North Truro Air Force Station, Massachusetts, was ready to make detection and calls for a scramble. Within three minutes the 133rd could be airborne and heading for a prospective rendezvous point. After
