The ground echelon moved to Camp Kilmer, then sailed on the RMS Queen Elizabeth to Scotland, arriving in May.

[4] The squadron was diverted to bombing priority tactical targets during the preparation for and execution of Operation Overlord, the invasion of Normandy in June 1944, attacking communications and coastal defenses.

The 336th attacked enemy troop concentrations during the Battle of the Bulge from December 1944 to January 1945 and bombed airfields to support Operation Varsity, the airborne assault across the Rhine in March.

From V-E Day until departing the theater in June, it transported liberated prisoners of war and displaced persons.

The squadron deployed with the entire 95th Bombardment Wing to Andersen Air Force Base, Guam from July to November 1955.

In the late 1950s, SAC established strategic wings to disperse its B-52s over a larger number of bases, thus making it more difficult for the Soviet Union to knock out the entire fleet with a surprise first strike.

[17] As part of this program, the squadron moved to Turner Air Force Base, Georgia in July 1959, where it was assigned to the 4138th Strategic Wing.

[1] Starting in 1960, one third of the squadron's aircraft were maintained on fifteen-minute alert, fully fueled, armed and ready for combat to reduce vulnerability to a Soviet missile strike.
