How many bombs did the U.S. drop each year from 2009–2020 according to Department of Defense and independent trackers?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
The publicly available tallies of U.S. munitions dropped from 2009–2020 show large year-to-year swings driven by operations in Afghanistan, Iraq and Syria, with independent trackers and some Pentagon releases reporting different scopes and — after early 2020 — gaps in official data; a complete, single DoD-authored year-by-year table for 2009–2020 is not provided in the sources supplied here [1] [2]. Where reporters and trackers have compiled figures, 2009 is reported at roughly 4,200–4,300 bombs, mid‑decade figures decline, and 2019 spikes to record levels in Afghanistan (around 7,400) before official U.S. publication tapered off in 2020 [3] [4] [5].
1. What the Pentagon published and what independent trackers count
The Department of Defense historically published Airpower Summary tallies that documented weapons released in U.S.-led air campaigns, and independent researchers and NGOs have compiled overlapping datasets from those releases and regional commands; reporting notes that monthly DoD-style reports ran through February 2020 but the Trump administration halted routine public releases afterward, creating a transparency gap for 2020 onward [1] [2]. Independent trackers such as New America, the Bureau of Investigative Journalism and media outlets have therefore filled in years and theatres from public CJTF/USCENTCOM releases and other sources, producing year-by-year estimates that are frequently cited in summaries like the 24/7 Wall St. compilation used here [6] [3].
2. Year-by-year snapshots the reporting provides (high-confidence examples)
A readily available compilation cited by mainstream outlets lists 2009 at about 4,289 weapons released and shows substantial variation across the decade — for example, mid‑decade declines associated with tighter rules of engagement in 2015 and dramatic increases by 2019 — but the provided material does not supply a single DoD table of every year from 2009–2020 in one place [3] [4]. Several reports cite 2019 as especially notable: U.S. and coalition warplanes expended roughly 7,423–7,500 bombs and munitions in Afghanistan alone in 2019, the highest annual total since Pentagon tracking began [4] [7].
3. Discrepancies and what they mean
Different sources count different scopes — global U.S. weapons releases versus weapons in specific theatres (e.g., Afghanistan only) — and use varying inputs (regional command tallies, press releases, NGO reconstructions), which produces divergent year totals; for example, 2009 Afghanistan-only reports sometimes list 4,147 while broader compilations list the total weapons released that year at roughly 4,289 [5] [3]. Analysts warn that changes in rules of engagement (notably under Secretary Mattis) and operational tempo explain much of the 2015–2019 swing, while the cessation of routine public DoD monthly reporting in 2020 means independent trackers must rely on partial releases and nonstandard sources thereafter [8] [1].
4. The 2020 problem: missing official granularity
Multiple commentators and advocacy groups note that after February 2020 the administration stopped publishing the same monthly Airpower Summary figures, leaving 2020 data incomplete in official public form and forcing researchers to reconstruct that year’s numbers from ad hoc releases and regional command reports; Progressive and Stop the War summarize this break in transparency and the consequences for tallying bombs by year [1] [2]. Where the new Biden-era Airpower Summary later provided some figures for 2020–21, the patchwork nature of releases means a fully consistent DoD-driven annual series from 2009–2020 is not present in the supplied sources [1].
5. Bottom line and limits of available reporting
The sources supplied allow confident citation of specific headline figures — e.g., roughly 4,200–4,300 weapons in 2009 and a 2019 Afghanistan high of about 7,400 weapons — and point to comprehensive compilations such as the 24/7 Wall St. summary for more year-by-year entries [3] [4]. However, because no single, unbroken DoD-authored table covering each calendar year 2009–2020 was included among the documents provided, a definitive DoD-only annual list for every year in that span cannot be fully reproduced here without consulting additional Pentagon archives or the trackers’ full datasets [1] [6].
