The Fairchild Republic A-10 Thunderbolt II is a U.S. Air Force attack aircraft built for close air support. It is widely known as the “Warthog” for its rugged look and distinctive cannon sound.

What it is

The A-10 is a single-seat, twin-engine jet designed around the 30 mm GAU-8/A Avenger rotary cannon. Its official name, Thunderbolt II, honours the World War II P-47. The aircraft entered service in 1976 and remains focused on supporting ground troops.

Why it matters

The A-10 was the first Air Force plane built solely for close air support. Its heavy armour, low-speed agility, and powerful cannon make it effective against tanks and fortified positions. It also performs forward air control, combat search and rescue, and maritime patrol.

Key details

The airframe is rugged and survivable, with twin General Electric TF34 turbofans. The GAU-8/A cannon fires depleted uranium rounds and is considered the aircraft’s signature weapon. The A-10 can carry a wide range of bombs, rockets, and missiles for ground attack.
