Stambaugh's home state of Pennsylvania was notoriously named the "Arsenal of America" due to its extensive industrial capabilities and weapon manufacturing. The city of Pittsburgh's booming steel industry significantly helped the war effort with steel being used in weapon and vehicle production. Pennsylvania accounted for 31% of the US steel production, and 20% of worldwide production at the time. The dairy and agriculture industry in Pennsylvania were also thriving which only added to the state's significant contribution towards the war. Pennsylvania also benefited from a convenient geographical location to the East Coast for easy export to the fight in Europe. Pennsylvania was home to over forty military bases, the larger ones being the Philadelphia Navy Yard and the Carlisle Barracks.
