There is no single, official count that breaks “military aircraft crashes and mishaps during the Biden administration” into one neat number, but available Pentagon data and news reports show a clear pattern: fatal and very costly military aviation mishaps rose sharply during Biden’s term, peaking in fiscal year 2024 (which ended in September 2024, still under Biden).

What the numbers actually say

The key data point comes from a Pentagon dataset shared with Senator Elizabeth Warren and analyzed by Defense One and Military Times:

  • Between full budget years 2020 through 2023 and part of 2024 (a period that largely overlaps with the Biden administration), the U.S. military recorded 4,280 total mishaps across all classes.
  • These mishaps resulted in:
    • 90 deaths
    • Nearly 90 aircraft destroyed
    • Over $9 billion in damages.

This 4-year window includes:

  • Most of the Trump administration (FY 2020),
  • Almost all of the Biden administration (FY 2021, FY 2022, FY 2023, and most of FY 2024).

So while the 4,280 mishaps and 90 deaths are not exclusively Biden-era, the majority of them occurred during his presidency.

Class A (deadliest/costliest) mishaps

Class A mishaps are the most serious category: they involve fatalities, permanent disablement, or damage over $2.5 million.

  • The Class A mishap rate per 100,000 flight hours rose from:
    • 1.3 in FY 2020 to
    • 2.02 in FY 2024 – a 55% increase over four years.
  • In the Army alone , FY 2024 saw:
    • 17 Class A mishaps (15 during flight, 2 ground),
    • A rate of 1.9 per 100,000 flight hours , the highest since 2007.
  • The article notes that FY 2024 was the year before the January 2025 DC Black Hawk–airliner collision , which killed 67 people, and that the Army’s mishap rate had already spiked during Biden’s term.

Across services:

  • Marines : rate nearly doubled (1.33 → 3.91).
  • Army : 0.76 → 2.02.
  • Air Force : 1.72 → 1.9.
  • Navy : 1.12 → 1.76 (after peaking at 1.98 in 2022).

All of these increases occurred mostly during 2021–2024 , i.e., under Biden.

Why there isn’t a single “Biden-only” count

Several factors make a clean “Biden administration only” number unavailable in public sources:

  1. Mishap data is reported by fiscal year (FY), not by presidential term.
    • FY 2020 overlaps Trump’s last year.
    • FY 2024 ended in September 2024, still under Biden.
    • Few public reports break mishaps down by exact months or by which president was in office.
  2. Most summaries give 4-year totals (2020–2024) rather than 2021–2024.
    • The widely cited 4,280 mishaps and 90 deaths cover FY 2020–2024, not just Biden’s time.
  1. Mishaps include many non-crash incidents.
    • The term “mishap” covers ground accidents, minor injuries, and damage events that don’t involve crashes.
    • Few sources separate “crashes” from “all mishaps” in a way that isolates the Biden years.

What we can reasonably infer

From the available data:

  • The trend is clear: military aviation mishaps, especially Class A, increased significantly during the Biden administration , with the highest rates in FY 2024.
  • The bulk of the 4,280 mishaps and 90 deaths occurred in FY 2021–2024 , which is almost entirely within Biden’s term.
  • There is no published, precise count that says “X crashes and Y mishaps happened only during the Biden administration.”

If you need a ballpark:

  • You can say that several hundred Class A and Class B mishaps , and tens of fatal crashes , occurred during Biden’s presidency, based on the 2020–2024 dataset, with the majority falling in 2021–2024.

Context: why mishaps rose

Experts and reports point to several contributing factors during this period:

  • Stagnating or inflation-eroded budgets while operational tempo remained high.
  • Aging aircraft fleets and maintenance challenges, including parts cannibalization to keep planes flying.
  • Increased operations and training demands , putting more stress on maintenance and pilot experience levels.
  • In the Army, a safety “stand-up” after a spike in mishaps in early FY 2024 later reduced the Class A rate from 1.9 to 0.86 per 100,000 flight hours for the remainder of the year.

Bottom line:
There is no single official figure that isolates “military aircraft crashes and mishaps during the Biden administration” alone. However, Pentagon data covering FY 2020–2024 shows 4,280 total mishaps, 90 deaths, nearly 90 aircraft destroyed, and over $9 billion in damages , with the worst rates occurring in FY 2021–2024 —the core of Biden’s term.
