On the fourth day of the war, the presence of American fuel tankers over Israel has been significant, emphasizing their role in modern warfare beyond just the number of combat aircraft. The logistical support provided by fuel tankers is crucial for maintaining air operations as each long-range strike requires a complex support network to extend the aircraft's operational capacity. Al Jazeera’s open source unit has been tracking the movements of these tankers, which show intensified activity over Israel and its coasts, coinciding with the joint American-Israeli bombing operations targeting Iran.

Recent navigational data indicates that nine American fuel tankers departed from Tel Aviv airport heading eastward, alongside the arrival of eight others from various bases. Additionally, several tankers maintained circular flying patterns in the area, which illustrates a high turnover rate necessary for prolonged military operations rather than isolated strikes. This pattern of repeated flights signifies support for multiple wave operations, showcasing the ongoing military strategy rather than a singular event.

The article points out that each fuel tanker can keep several fighter jets or bombers airborne for hours, thereby facilitating sustained airstrikes rather than intermittent bombings. This aerial refueling capability allows for a continued aerial presence which is essential when engaging in multiple strikes against a target like Iran, indicating that the current military engagements involve an extensive and complex logistical operation.
