A badass airplane with a big gun on it.”

That’s how Republican Congresswoman Martha McSally described the A-10 Warthog to President Donald Trump, as she told the Center for Strategic and International Studies on Tuesday.

McSally, the first female fighter pilot and a veteran of Iraq and Afghanistan, told the crowd at the CSIS event about her experiences as an A-10 pilot laying down close air support for US troops during the 2000s.

“It’s an amazing airplane to fly, but it’s really cool to shoot the gun,” said McSally. “The folklore as A-10 pilots that we pass around is that we built the gun, and told the engineers ‘figure out how to fly this gun.’”

“The gun, 30 millimeters is just amazing.” said McSally. “When you shoot the gun, the whole airplane shakes. The first time you shoot the gun, you think the airplane’s breaking up.”

Perhaps better known is the iconic “BRRRT” sound of the A-10’s 30 mm, 1,174 round gun as heard from the ground, a sound that US infantrymen have come to equate with salvation and safety.

In practice, the A-10’s gun is actually more precise than even the newest, most accurate GPS or laser-guided bombs, which can often cost up to a million dollars each.

“In Afghanistan … we used mostly the gun,” said McSally, “It’s a very precise ωεɑρσռ and it allows for minimizing collateral damage and fratricide because the ωεɑρσռ’s footprint is so tight. We can roll in and precisely go after the target while it keeps Americans safe.”
