From 1958, the Boeing B-47 Stratojet wings of Strategic Air Command (SAC) began to assume an alert posture at their home bases, reducing the amount of time spent on alert at overseas bases.
 The SAC alert cycle divided itself into four parts: planning, flying, alert and rest to meet General Thomas S. Power's initial goal of maintaining one third of SAC’s planes on fifteen minute ground alert, fully fueled and ready for combat to reduce vulnerability to a Soviet missile strike.
To implement this new system B-47 wings reorganized from three to four squadrons.
The 415th was activated at Lincoln Air Force Base as the fourth squadron of the 98th Bombardment Wing.
The alert commitment was increased to half the wing's aircraft in 1962 and the four squadron pattern no longer met the alert cycle commitment, so the squadron was inactivated on 1 January 1962.
