The A-10 Thunderbolt II first entered service in March 1976, and is the predecessor to the P-47 Thunderbolt — but it didn't see action until the Gulf War.
The A-10 was also developed by Fairchild Republic Co., which is now owned by Northrop Grumman, one of the largest defense contractors and political donors in the US.

The original design revolved around the GAU-8 Avenger 30mm gatling gun, which fires 3,900 armor-piercing depleted uranium and high explosive incendiary rounds per minute.

The Warthog is powered by two General Electric TF34-GE-100 turbofans, each giving the A-10 about 9,065 pounds of thrust.

The grunt has a top speed of about 450 mph, can hit altitudes of 45,000 feet, and has a range of 2,580 miles.
The A-10 was also the first Air Force aircraft to be powered by biofuels, and is the American counterpart to the Russian Su-25.

In addition to the gatling gun, which sticks out of the teeth often painted on the nose cone and emits smoke like a cigarette when firing, the A-10 carries a payload of up to 16,000 pounds.

And even 2.75-inch rockets, AIM-9 Sidewinder missiles, AGM-65 Maverick missiles, and laser-guided/electro-optically guided bombs.
It also carries infrared countermeasure flares, electronic countermeasure chaffs, jammer pods, and illumination flares.
The Warthog's first air-to-air victory came in 1991 when Capt. Robert Swain shot down an Iraqi helicopter with the gatling gun.
The Warthog's iconic nose art, usually showing terrifying barred teeth, is part of a war paint tradition dating back to World War II.
It has saved US ground troops in Iraq, Afghanistan, and Syria multiple times, making it a favorite among American service members who see the A-10 as a guardian angel.

Speculation has abounded for years about the fate of the A-10 until 2017, when Congress allocated over $100 million to upgrade it.

US Air Force Secretary Heather Wilson even told the Senate Armed Services Committee in December that "I happen to be a fan of the A-10."
