It is a semi-armor-piercing high-explosive incendiary (SAPHEI) round, providing improvements in range, accuracy, and power over the preceding M56A3 HEI round. [18] The PGU-28/B is a "low-drag" round designed to reduce in-flight drag and deceleration, and has a slightly increased muzzle velocity of 1,050 metres per second (3,450 ft/s). [19]
The resulting weapon used a smaller version of the GAU-8/A, designated the GAU-13/A, with only four barrels.

The pod is completely self-contained with a rate of fire of 3,000 rpm. [19]
