In the last three weeks, six military aviation crashes have killed 16 pilots or crew — a tragic development that has cast a spotlight on a growing crisis: Accident rates have soared over the last five years for most of the military’s manned warplanes.

Through a six-month investigation, the Military Times found that accidents involving all of the military’s manned fighter, bomber, helicopter and cargo warplanes rose nearly 40 percent from fiscal years 2013 to 2017. It’s doubled for some aircraft, like the Navy and Marine Corps’ F/A-18 Hornets and Super Hornets. At least 133 service members were killed in those fiscal year 2013-2017 mishaps, according to data obtained by Military Times.
