The A-10 Warthog, officially known as the Thunderbolt II, is a single-seat, twin-engine jet aircraft designed for close air support (CAS) missions. One of its most distinctive features is the 30mm GAU-8/A Avenger cannon, which is capable of firing a variety of ammunition types, including the PGU-14/B Armor Piercing (AP) round and the PGU-13/B High Explosive Incendiary (HEI) round. However, when discussing a "10 Warthog Bullet," it's likely referring to the PGU-14/B, a 30mm bullet specifically designed for the A-10's cannon.
Characteristics of the PGU-14/B Bullet

The PGU-14/B is an armor-piercing round, designed to penetrate armored vehicles and fortifications. It is made of depleted uranium (DU), which provides a high density and hardness, allowing it to maintain its shape and penetrate deep into armored targets. The bullet has a length of approximately 11.8 inches (300 mm) and weighs around 1.5 pounds (680 grams). The PGU-14/B has a muzzle velocity of about 2,500 feet per second (762 meters per second) when fired from the A-10’s GAU-8/A cannon.
Performance of the PGU-14/B in Combat Scenarios
In combat, the PGU-14/B has proven to be highly effective against a variety of targets, including tanks, armored personnel carriers, and bunkers. The depleted uranium core allows the bullet to penetrate even the thickest armor, causing significant damage and often resulting in a “kinetic kill,” where the target is destroyed or disabled due to the force of the impact. The PGU-14/B’s performance has been consistently demonstrated in various conflicts, including the Gulf War and the Iraq War, where A-10s played a crucial role in providing close air support to ground troops.
