A standard A-10 gun run lasts two to three seconds. Finger on the trigger, a controlled burst of 30mm depleted uranium rounds, then pull off target. That's what pilots train for. That's what the manual says. So when video surfaced from Iraq showing Warthogs holding the trigger for six seconds — and in one case, a full nine — experienced A-10 pilots did a double take.

"That definitely isn't normal or really trained for," one veteran Warthog pilot said after watching the footage. Dale Stark, a former A-10 pilot, confirmed that standard gun passes "usually run two to three seconds." What's happening over Iraq right now is something else entirely.

The videos went viral across aviation and military communities. The unmistakable sound of the GAU-8 Avenger — a deep, ripping growl that sounds less like a gun and more like a zipper tearing across the sky — lasted far longer than anyone expected. The implications are both fascinating and unsettling.

585 Rounds in Nine Seconds

The GAU-8 Avenger fires at approximately 3,900 rounds per minute — roughly 65 rounds per second. A standard two-second burst sends about 130 rounds downrange. A nine-second run dumps 585. The A-10 carries 1,174 rounds total. Do the math: a single extended pass eats through half the magazine.

Each round is 30mm across and weighs nearly a pound. The armor-piercing variant, the PGU-14/B, carries a depleted uranium penetrator that punches through tank armor. The standard combat mix loads five armor-piercing rounds for every one high-explosive incendiary. At 4,000 feet of slant range, 80 percent of those rounds land inside a 40-foot circle.

That is an extraordinary amount of firepower to pour into a single pass. And it raises an immediate question: why?

Strafe Targets vs. Point Targets

The answer likely comes down to target geometry. A-10 pilots distinguish between point targets — a single vehicle, a bunker, a gun position — and strafe targets: linear or distributed threat areas where the danger is spread out. Militia positions along a road, a column of vehicles, a defensive line.

Against a strafe target, the pilot walks the cannon fire across the entire length of the threat area. That takes longer. The run stretches from the standard two-second snap to something more deliberate. But even accounting for this, nine seconds is extreme. Multiple pilots consulted on the footage confirmed it sits well outside normal tactical employment.

One former Warthog pilot suggested the extended runs might serve a psychological purpose as much as a tactical one. "The sound of that gun carries for miles," said retired Lt. Col. David Gruber, a former A-10 instructor pilot. "There's a reason they call it the sound of freedom. Holding the trigger longer sends a message."

The Risk Calculus

Every second on a gun run is a second the aircraft is predictable. Flying straight. Wings level. Nose pointed at the target. It's the most vulnerable an A-10 gets. The primary air defense threat in the Iraq theater right now is MANPADS — shoulder-fired missiles that can be launched from a rooftop or a pickup truck with zero warning.

A three-second pass limits exposure. A nine-second pass triples it. That's a conscious decision by pilots who know exactly what they're risking. Whatever they're shooting at, they've decided the firepower is worth the danger.

Extended runs also generate enormous barrel heat. The GAU-8's seven rotating barrels distribute thermal stress, but nine continuous seconds pushes the system hard. Accuracy degrades as metal expands. The last rounds in a long burst don't land as precisely as the first.

Something about the targets in Iraq — their size, their distribution, or the urgency of the threat — is pushing Warthog pilots beyond the textbook. In a war full of surprises, the A-10 is writing new chapters in real time.
