In which conflict did the U.S. military first utilize aircraft for reconnaissance purposes?

The U.S. military first utilized aircraft for reconnaissance purposes during World War I. This conflict marked a significant shift in military strategy, as aircraft were adapted not only for combat but also for gathering intelligence. Reconnaissance missions allowed military leaders to gain critical information about enemy positions and movements, which was vital for planning operations and coordinating troop movements.

Before World War I, aircraft were primarily viewed as a novelty rather than a serious component of military operations. However, the war demonstrated the advantages that aerial surveillance could provide. Observers in aircraft could cover vast areas quickly and could relay information back to commanders, influencing the outcome of battles.

The use of reconnaissance aircraft laid the groundwork for future advancements in military aviation, including more specialized roles and technologies in subsequent conflicts, but it was during World War I that these concepts were first put into effective practice.
