In 1960, the mission of the NH Air National Guard changed to air transport in time for their participation in the Berlin Crisis of 1961. This is also when they received their present 157th designation. In the mid-1960s, the 157th moved to Pease Air Force Base, from which they also began flying logistical support to U.S. troops in Vietnam. In 1974, the NH Air National Guard received its current mission as in-flight refuelers.
