The US-led coalition fighting ISIS in Iraq and Afghanistan dropped 5,075 bombs during close-air-support, escort, or interdiction operations in August, according to US Air Forces Central Command data, the Business Insider reported.
The August total was the highest of any month during the three-year campaign against the terrorist group.
The previous monthly high was 4,848 in June. Each of first eight months of 2017 has exceeded the amount of bombs dropped in any other month of the campaign.
The number of weapons released through the first eight months of 2017 is 32,801, surpassing the 30,743 dropped all last year, which was the previous annual high for the campaign.
The 13,109 sorties so far this year is on pace to fall short of the total in 2016 and 2015 — both of which exceeded 21,100. The 8,249 sorties with at least one weapon deployed so far this year are set to top last year's 11,825, however.
Both Iraq and Syria have seen intense urban fighting this year, which often requires more active air support.
The battle to retake Mosul in Iraq began in October 2016 and formally ended in July, while the final stage of fighting for Raqqa, ISIS' self-declared capital in Syria, began in June and is ongoing.
Not all aircraft active over Iraq and Syria are under Air Forces Central Command's control, so the figures likely understate the total number of weapons deployed.
